The town of Gilbert, Arizona (or Town), has adopted a comprehensive code governing the manner in which people may display outdoor signs. Gilbert, Ariz., Land Development Code (Sign Code or Code), ch. 1, § 4.402 (2005). 1 The Sign Code identifies various categories of signs based on the type of information they convey, then subjects each category to different restrictions. One of the categories is "Temporary Directional Signs Relating to a Qualifying Event," loosely defined as signs directing the public to a meeting of a nonprofit group. § 4.402(P). The Code imposes more stringent restrictions on these signs than it does on signs conveying other messages. We hold that these provisions are content-based regulations of speech that cannot survive strict scrutiny.

A

The Sign Code prohibits the display of outdoor signs anywhere within the Town without a permit, but it then exempts 23 categories of signs from that requirement. These exemptions include everything from bazaar signs to flying banners. Three categories of exempt signs are particularly relevant here.

The first is "Ideological Sign[s]." This category includes any "sign communicating a message or ideas for noncommercial purposes that is not a Construction Sign, Directional Sign, Temporary Directional Sign Relating to a Qualifying Event, Political Sign, Garage Sale Sign, or a sign owned or required by a governmental agency." Sign Code, Glossary of General Terms (Glossary), p. 23 (emphasis deleted). Of the three categories discussed here, the Code treats ideological signs most favorably, allowing them to be up to 20 square feet in area and to be placed in all "zoning districts" without time limits. § 4.402(J).

The second category is "Political Sign[s]." This includes any "temporary sign designed to influence the outcome of an election called by a public body." Glossary 23. 2 The Code treats these signs less favorably than ideological signs. The Code allows the placement of political signs up to 16 square feet on residential property and up to 32 square feet on nonresidential property, undeveloped municipal property, and "rights-of-way."

*2225 § 4.402(I). 3 These signs may be displayed up to 60 days before a primary election and up to 15 days following a general election. Ibid.

The third category is "Temporary Directional Signs Relating to a Qualifying Event." This includes any "Temporary Sign intended to direct pedestrians, motorists, and other passersby to a 'qualifying event.' " Glossary 25 (emphasis deleted). A "qualifying event" is defined as any "assembly, gathering, activity, or meeting sponsored, arranged, or promoted by a religious, charitable, community service, educational, or other similar non-profit organization." Ibid. The Code treats temporary directional signs even less favorably than political signs. 4 Temporary directional signs may be no larger than six square feet. § 4.402(P). They may be placed on private property or on a public right-of-way, but no more than four signs may be placed on a single property at any time. Ibid . And, they may be displayed no more than 12 hours before the "qualifying event" and no more than 1 hour afterward. Ibid.

Petitioners Good News Community Church (Church) and its pastor, Clyde Reed, wish to advertise the time and location of their Sunday church services. The Church is a small, cash-strapped entity that owns no building, so it holds its services at elementary schools or other locations in or near the Town. In order to inform the public about its services, which are held in a variety of different locations, the Church began placing 15 to 20 temporary signs around the Town, frequently in the public right-of-way abutting the street. The signs typically displayed the Church's name, along with the time and location of the upcoming service. Church members would post the signs early in the day on Saturday and then remove them around midday on Sunday. The display of these signs requires little money and manpower, and thus has proved to be an economical and effective way for the Church to let the community know where its services are being held each week.

This practice caught the attention of the Town's Sign Code compliance manager, who twice cited the Church for violating the Code. The first citation noted that the Church exceeded the time limits for displaying its temporary directional signs. The second citation referred to the same problem, along with the Church's failure to include the date of the event on the signs. Town officials even confiscated one of the Church's signs, which Reed had to retrieve from the municipal offices.

Reed contacted the Sign Code Compliance Department in an attempt to reach an accommodation. His efforts proved unsuccessful. The Town's Code compliance manager informed the Church that there *2226 would be "no leniency under the Code" and promised to punish any future violations.

Shortly thereafter, petitioners filed a complaint in the United States District Court for the District of Arizona, arguing that the Sign Code abridged their freedom of speech in violation of the First and Fourteenth Amendments. The District Court denied the petitioners' motion for a preliminary injunction. The Court of Appeals for the Ninth Circuit affirmed, holding that the Sign Code's provision regulating temporary directional signs did not regulate speech on the basis of content. 587 F.3d 966 , 979 (2009). It reasoned that, even though an enforcement officer would have to read the sign to determine what provisions of the Sign Code applied to it, the " 'kind of cursory examination' " that would be necessary for an officer to classify it as a temporary directional sign was "not akin to an officer synthesizing the expressive content of the sign." Id., at 978. It then remanded for the District Court to determine in the first instance whether the Sign Code's distinctions among temporary directional signs, political signs, and ideological signs nevertheless constituted a content-based regulation of speech.

On remand, the District Court granted summary judgment in favor of the Town. The Court of Appeals again affirmed, holding that the Code's sign categories were content neutral. The court concluded that "the distinctions between Temporary Directional Signs, Ideological Signs, and Political Signs ... are based on objective factors relevant to Gilbert's creation of the specific exemption from the permit requirement and do not otherwise consider the substance of the sign." 707 F.3d 1057 , 1069 (C.A.9 2013). Relying on this Court's decision in Hill v. Colorado, 530 U.S. 703 , 120 S.Ct. 2480 , 147 L.Ed.2d 597 (2000), the Court of Appeals concluded that the Sign Code is content neutral. 707 F.3d, at 1071-1072 . As the court explained, "Gilbert did not adopt its regulation of speech because it disagreed with the message conveyed" and its "interests in regulat[ing] temporary signs are unrelated to the content of the sign." Ibid. Accordingly, the court believed that the Code was "content-neutral as that term [has been] defined by the Supreme Court." Id., at 1071. In light of that determination, it applied a lower level of scrutiny to the Sign Code and concluded that the law did not violate the First Amendment. Id., at 1073-1076.

We granted certiorari, 573 U.S. ----, 134 S.Ct. 2900 , 189 L.Ed.2d 854 (2014), and now reverse.

A

The First Amendment, applicable to the States through the Fourteenth Amendment, prohibits the enactment of laws "abridging the freedom of speech." U.S. Const., Amdt. 1. Under that Clause, a government, including a municipal government vested with state authority, "has no power to restrict expression because of its message, its ideas, its subject matter, or its content." Police Dept. of Chicago v. Mosley, 408 U.S. 92 , 95, 92 S.Ct. 2286 , 33 L.Ed.2d 212 (1972). Content-based laws-those that target speech based on its communicative content-are presumptively unconstitutional and may be justified only if the government proves that they are narrowly tailored to serve compelling state interests. R.A.V. v. St. Paul, 505 U.S. 377 , 395, 112 S.Ct. 2538 , 120 L.Ed.2d 305 (1992); Simon & Schuster, Inc. v. Members of N.Y. State Crime Victims Bd., 502 U.S. 105 , 115, 118, 112 S.Ct. 501 , 116 L.Ed.2d 476 (1991).

*2227 Government regulation of speech is content based if a law applies to particular speech because of the topic discussed or the idea or message expressed. E.g., Sorrell v. IMS Health, Inc., 564 U.S. ----, ---- - ----, 131 S.Ct. 2653 , 2663-2664, 180 L.Ed.2d 544 (2011); Carey v. Brown, 447 U.S. 455 , 462, 100 S.Ct. 2286 , 65 L.Ed.2d 263 (1980); Mosley, supra, at 95, 92 S.Ct. 2286 . This commonsense meaning of the phrase "content based" requires a court to consider whether a regulation of speech "on its face" draws distinctions based on the message a speaker conveys. Sorrell, supra, at ----, 131 S.Ct., at 2664 . Some facial distinctions based on a message are obvious, defining regulated speech by particular subject matter, and others are more subtle, defining regulated speech by its function or purpose. Both are distinctions drawn based on the message a speaker conveys, and, therefore, are subject to strict scrutiny.

Our precedents have also recognized a separate and additional category of laws that, though facially content neutral, will be considered content-based regulations of speech: laws that cannot be " 'justified without reference to the content of the regulated speech,' " or that were adopted by the government "because of disagreement with the message [the speech] conveys," Ward v. Rock Against Racism, 491 U.S. 781 , 791, 109 S.Ct. 2746 , 105 L.Ed.2d 661 (1989) . Those laws, like those that are content based on their face, must also satisfy strict scrutiny.

B

The Town's Sign Code is content based on its face. It defines "Temporary Directional Signs" on the basis of whether a sign conveys the message of directing the public to church or some other "qualifying event." Glossary 25. It defines "Political Signs" on the basis of whether a sign's message is "designed to influence the outcome of an election." Id., at 24. And it defines "Ideological Signs" on the basis of whether a sign "communicat [es] a message or ideas" that do not fit within the Code's other categories. Id., at 23. It then subjects each of these categories to different restrictions.

The restrictions in the Sign Code that apply to any given sign thus depend entirely on the communicative content of the sign. If a sign informs its reader of the time and place a book club will discuss John Locke's Two Treatises of Government, that sign will be treated differently from a sign expressing the view that one should vote for one of Locke's followers in an upcoming election, and both signs will be treated differently from a sign expressing an ideological view rooted in Locke's theory of government. More to the point, the Church's signs inviting people to attend its worship services are treated differently from signs conveying other types of ideas. On its face, the Sign Code is a content-based regulation of speech. We thus have no need to consider the government's justifications or purposes for enacting the Code to determine whether it is subject to strict scrutiny.

C

In reaching the contrary conclusion, the Court of Appeals offered several theories to explain why the Town's Sign Code should be deemed content neutral. None is persuasive.

1

The Court of Appeals first determined that the Sign Code was content neutral because the Town "did not adopt its regulation of speech [based on] disagree [ment] with the message conveyed," and its justifications for regulating temporary directional signs were "unrelated to the content of the sign." 707 F.3d, at 1071-1072 .

*2228 In its brief to this Court, the United States similarly contends that a sign regulation is content neutral-even if it expressly draws distinctions based on the sign's communicative content-if those distinctions can be " 'justified without reference to the content of the regulated speech.' " Brief for United States as Amicus Curiae 20, 24 (quoting Ward, supra, at 791, 109 S.Ct. 2746 ; emphasis deleted).

But this analysis skips the crucial first step in the content-neutrality analysis: determining whether the law is content neutral on its face. A law that is content based on its face is subject to strict scrutiny regardless of the government's benign motive, content-neutral justification, or lack of "animus toward the ideas contained" in the regulated speech. Cincinnati v. Discovery Network, Inc., 507 U.S. 410 , 429, 113 S.Ct. 1505 , 123 L.Ed.2d 99 (1993). We have thus made clear that " '[i]llicit legislative intent is not the sine qua non of a violation of the First Amendment,' " and a party opposing the government "need adduce 'no evidence of an improper censorial motive.' " Simon & Schuster, supra, at 117, 112 S.Ct. 501 . Although "a content-based purpose may be sufficient in certain circumstances to show that a regulation is content based, it is not necessary." Turner Broadcasting System, Inc. v. FCC, 512 U.S. 622 , 642, 114 S.Ct. 2445 , 129 L.Ed.2d 497 (1994). In other words, an innocuous justification cannot transform a facially content-based law into one that is content neutral.

That is why we have repeatedly considered whether a law is content neutral on its face before turning to the law's justification or purpose. See, e.g., Sorrell, supra, at ---- - ----, 131 S.Ct., at 2663-2664 (statute was content based "on its face," and there was also evidence of an impermissible legislative motive); United States v. Eichman, 496 U.S. 310 , 315, 110 S.Ct. 2404 , 110 L.Ed.2d 287 (1990)("Although the [statute] contains no explicit content-based limitation on the scope of prohibited conduct, it is nevertheless clear that the Government's asserted interest is related to the suppression of free expression" (internal quotation marks omitted)); Members of City Council of Los Angeles v. Taxpayers for Vincent, 466 U.S. 789 , 804, 104 S.Ct. 2118 , 80 L.Ed.2d 772 (1984)("The text of the ordinance is neutral," and "there is not even a hint of bias or censorship in the City's enactment or enforcement of this ordinance"); Clark v. Community for Creative Non-Violence, 468 U.S. 288 , 293, 104 S.Ct. 3065 , 82 L.Ed.2d 221 (1984)(requiring that a facially content-neutral ban on camping must be "justified without reference to the content of the regulated speech"); United States v. O'Brien, 391 U.S. 367 , 375, 377, 88 S.Ct. 1673 , 20 L.Ed.2d 672 (1968)(noting that the statute "on its face deals with conduct having no connection with speech," but examining whether the "the governmental interest is unrelated to the suppression of free expression"). Because strict scrutiny applies either when a law is content based on its face or when the purpose and justification for the law are content based, a court must evaluate each question before it concludes that the law is content neutral and thus subject to a lower level of scrutiny.

The Court of Appeals and the United States misunderstand our decision in Ward as suggesting that a government's purpose is relevant even when a law is content based on its face. That is incorrect. Ward had nothing to say about facially content-based restrictions because it involved a facially content- neutral ban on the use, in a city-owned music venue, of sound amplification systems not provided by the city. 491 U.S., at 787 , and n. 2, 109 S.Ct. 2746 . In that context, we looked to *2229 governmental motive, including whether the government had regulated speech "because of disagreement" with its message, and whether the regulation was " 'justified without reference to the content of the speech.' " Id., at 791, 109 S.Ct. 2746 . But Ward 's framework "applies only if a statute is content neutral." Hill, 530 U.S., at 766 , 120 S.Ct. 2480 (KENNEDY, J., dissenting). Its rules thus operate "to protect speech," not "to restrict it." Id., at 765, 120 S.Ct. 2480 .

The First Amendment requires no less. Innocent motives do not eliminate the danger of censorship presented by a facially content-based statute, as future government officials may one day wield such statutes to suppress disfavored speech. That is why the First Amendment expressly targets the operation of the laws- i.e., the "abridg[ement] of speech"-rather than merely the motives of those who enacted them. U.S. Const., Amdt. 1. " 'The vice of content-based legislation ... is not that it is always used for invidious, thought-control purposes, but that it lends itself to use for those purposes.' " Hill, supra, at 743, 120 S.Ct. 2480 (SCALIA, J., dissenting).

For instance, in NAACP v. Button, 371 U.S. 415 , 83 S.Ct. 328 , 9 L.Ed.2d 405 (1963), the Court encountered a State's attempt to use a statute prohibiting " 'improper solicitation' " by attorneys to outlaw litigation-related speech of the National Association for the Advancement of Colored People. Id., at 438, 83 S.Ct. 328 . Although Button predated our more recent formulations of strict scrutiny, the Court rightly rejected the State's claim that its interest in the "regulation of professional conduct" rendered the statute consistent with the First Amendment, observing that "it is no answer ... to say ... that the purpose of these regulations was merely to insure high professional standards and not to curtail free expression." Id., at 438-439, 83 S.Ct. 328 . Likewise, one could easily imagine a Sign Code compliance manager who disliked the Church's substantive teachings deploying the Sign Code to make it more difficult for the Church to inform the public of the location of its services. Accordingly, we have repeatedly "rejected the argument that 'discriminatory ... treatment is suspect under the First Amendment only when the legislature intends to suppress certain ideas.' " Discovery Network, 507 U.S., at 429 , 113 S.Ct. 1505 . We do so again today.

2

The Court of Appeals next reasoned that the Sign Code was content neutral because it "does not mention any idea or viewpoint, let alone single one out for differential treatment." 587 F.3d, at 977 . It reasoned that, for the purpose of the Code provisions, "[i]t makes no difference which candidate is supported, who sponsors the event, or what ideological perspective is asserted." 707 F.3d, at 1069 .

The Town seizes on this reasoning, insisting that "content based" is a term of art that "should be applied flexibly" with the goal of protecting "viewpoints and ideas from government censorship or favoritism." Brief for Respondents 22. In the Town's view, a sign regulation that "does not censor or favor particular viewpoints or ideas" cannot be content based. Ibid . The Sign Code allegedly passes this test because its treatment of temporary directional signs does not raise any concerns that the government is "endorsing or suppressing 'ideas or viewpoints,' " id., at 27, and the provisions for political signs and ideological signs "are neutral as to particular ideas or viewpoints" within those categories. Id., at 37.

This analysis conflates two distinct but related limitations that the First *2230 Amendment places on government regulation of speech. Government discrimination among viewpoints-or the regulation of speech based on "the specific motivating ideology or the opinion or perspective of the speaker"-is a "more blatant" and "egregious form of content discrimination." Rosenberger v. Rector and Visitors of Univ. of Va., 515 U.S. 819 , 829, 115 S.Ct. 2510 , 132 L.Ed.2d 700 (1995). But it is well established that "[t]he First Amendment's hostility to content-based regulation extends not only to restrictions on particular viewpoints, but also to prohibition of public discussion of an entire topic." Consolidated Edison Co. of N.Y. v. Public Serv. Comm'n of N. Y., 447 U.S. 530 , 537, 100 S.Ct. 2326 , 65 L.Ed.2d 319 (1980).

Thus, a speech regulation targeted at specific subject matter is content based even if it does not discriminate among viewpoints within that subject matter. Ibid. For example, a law banning the use of sound trucks for political speech-and only political speech-would be a content-based regulation, even if it imposed no limits on the political viewpoints that could be expressed. See Discovery Network, supra, at 428, 113 S.Ct. 1505 . The Town's Sign Code likewise singles out specific subject matter for differential treatment, even if it does not target viewpoints within that subject matter. Ideological messages are given more favorable treatment than messages concerning a political candidate, which are themselves given more favorable treatment than messages announcing an assembly of like-minded individuals. That is a paradigmatic example of content-based discrimination.

3

Finally, the Court of Appeals characterized the Sign Code's distinctions as turning on " 'the content-neutral elements of who is speaking through the sign and whether and when an event is occurring.' " 707 F.3d, at 1069 . That analysis is mistaken on both factual and legal grounds.

To start, the Sign Code's distinctions are not speaker based. The restrictions for political, ideological, and temporary event signs apply equally no matter who sponsors them. If a local business, for example, sought to put up signs advertising the Church's meetings, those signs would be subject to the same limitations as such signs placed by the Church. And if Reed had decided to display signs in support of a particular candidate, he could have made those signs far larger-and kept them up for far longer-than signs inviting people to attend his church services. If the Code's distinctions were truly speaker based, both types of signs would receive the same treatment.

In any case, the fact that a distinction is speaker based does not, as the Court of Appeals seemed to believe, automatically render the distinction content neutral. Because "[s]peech restrictions based on the identity of the speaker are all too often simply a means to control content," Citizens United v. Federal Election Comm'n, 558 U.S. 310 , 340, 130 S.Ct. 876 , 175 L.Ed.2d 753 (2010), we have insisted that "laws favoring some speakers over others demand strict scrutiny when the legislature's speaker preference reflects a content preference," Turner, 512 U.S., at 658 , 114 S.Ct. 2445 . Thus, a law limiting the content of newspapers, but only newspapers, could not evade strict scrutiny simply because it could be characterized as speaker based. Likewise, a content-based law that restricted the political speech of all corporations would not become content neutral just because it singled out corporations as a class of speakers. See Citizens United, supra, at 340-341, 130 S.Ct. 876 . Characterizing a distinction *2231 as speaker based is only the beginning-not the end-of the inquiry.

Nor do the Sign Code's distinctions hinge on "whether and when an event is occurring." The Code does not permit citizens to post signs on any topic whatsoever within a set period leading up to an election, for example. Instead, come election time, it requires Town officials to determine whether a sign is "designed to influence the outcome of an election" (and thus "political") or merely "communicating a message or ideas for noncommercial purposes" (and thus "ideological"). Glossary 24. That obvious content-based inquiry does not evade strict scrutiny review simply because an event ( i.e., an election) is involved.

And, just as with speaker-based laws, the fact that a distinction is event based does not render it content neutral. The Court of Appeals cited no precedent from this Court supporting its novel theory of an exception from the content-neutrality requirement for event-based laws. As we have explained, a speech regulation is content based if the law applies to particular speech because of the topic discussed or the idea or message expressed. Supra, at 2226 - 2227. A regulation that targets a sign because it conveys an idea about a specific event is no less content based than a regulation that targets a sign because it conveys some other idea. Here, the Code singles out signs bearing a particular message: the time and location of a specific event. This type of ordinance may seem like a perfectly rational way to regulate signs, but a clear and firm rule governing content neutrality is an essential means of protecting the freedom of speech, even if laws that might seem "entirely reasonable" will sometimes be "struck down because of their content-based nature." City of Ladue v. Gilleo, 512 U.S. 43 , 60, 114 S.Ct. 2038 , 129 L.Ed.2d 36 (1994)(O'Connor, J., concurring).

III

Because the Town's Sign Code imposes content-based restrictions on speech, those provisions can stand only if they survive strict scrutiny, " 'which requires the Government to prove that the restriction furthers a compelling interest and is narrowly tailored to achieve that interest,' " Arizona Free Enterprise Club's Freedom Club PAC v. Bennett, 564 U.S. ----, ----, 131 S.Ct. 2806 , 2817, 180 L.Ed.2d 664 (2011)(quoting Citizens United, 558 U.S., at 340 , 130 S.Ct. 876 ). Thus, it is the Town's burden to demonstrate that the Code's differentiation between temporary directional signs and other types of signs, such as political signs and ideological signs, furthers a compelling governmental interest and is narrowly tailored to that end. See ibid .

The Town cannot do so. It has offered only two governmental interests in support of the distinctions the Sign Code draws: preserving the Town's aesthetic appeal and traffic safety. Assuming for the sake of argument that those are compelling governmental interests, the Code's distinctions fail as hopelessly underinclusive.

Starting with the preservation of aesthetics, temporary directional signs are "no greater an eyesore," Discovery Network, 507 U.S., at 425 , 113 S.Ct. 1505 , than ideological or political ones. Yet the Code allows unlimited proliferation of larger ideological signs while strictly limiting the number, size, and duration of smaller directional ones. The Town cannot claim that placing strict limits on temporary directional signs is necessary to beautify the Town while at the same time allowing unlimited numbers of other types of signs that create the same problem.

*2232 The Town similarly has not shown that limiting temporary directional signs is necessary to eliminate threats to traffic safety, but that limiting other types of signs is not. The Town has offered no reason to believe that directional signs pose a greater threat to safety than do ideological or political signs. If anything, a sharply worded ideological sign seems more likely to distract a driver than a sign directing the public to a nearby church meeting.

In light of this underinclusiveness, the Town has not met its burden to prove that its Sign Code is narrowly tailored to further a compelling government interest. Because a " 'law cannot be regarded as protecting an interest of the highest order, and thus as justifying a restriction on truthful speech, when it leaves appreciable damage to that supposedly vital interest unprohibited,' " Republican Party of Minn. v. White, 536 U.S. 765 , 780, 122 S.Ct. 2528 , 153 L.Ed.2d 694 (2002), the Sign Code fails strict scrutiny.

IV

Our decision today will not prevent governments from enacting effective sign laws. The Town asserts that an " 'absolutist' " content-neutrality rule would render "virtually all distinctions in sign laws ... subject to strict scrutiny," Brief for Respondents 34-35, but that is not the case. Not "all distinctions" are subject to strict scrutiny, only content-based ones are. Laws that are content neutral are instead subject to lesser scrutiny. See Clark, 468 U.S., at 295 , 104 S.Ct. 3065 .

The Town has ample content-neutral options available to resolve problems with safety and aesthetics. For example, its current Code regulates many aspects of signs that have nothing to do with a sign's message: size, building materials, lighting, moving parts, and portability. See, e.g., § 4.402(R). And on public property, the Town may go a long way toward entirely forbidding the posting of signs, so long as it does so in an evenhanded, content-neutral manner. See Taxpayers for Vincent, 466 U.S., at 817 , 104 S.Ct. 2118 (upholding content-neutral ban against posting signs on public property). Indeed, some lower courts have long held that similar content-based sign laws receive strict scrutiny, but there is no evidence that towns in those jurisdictions have suffered catastrophic effects. See, e.g., Solantic, LLC v. Neptune Beach, 410 F.3d 1250 , 1264-1269 (C.A.11 2005)(sign categories similar to the town of Gilbert's were content based and subject to strict scrutiny); Matthews v. Needham, 764 F.2d 58 , 59-60 (C.A.1 1985)(law banning political signs but not commercial signs was content based and subject to strict scrutiny).

We acknowledge that a city might reasonably view the general regulation of signs as necessary because signs "take up space and may obstruct views, distract motorists, displace alternative uses for land, and pose other problems that legitimately call for regulation." City of Ladue, 512 U.S., at 48 , 114 S.Ct. 2038 . At the same time, the presence of certain signs may be essential, both for vehicles and pedestrians, to guide traffic or to identify hazards and ensure safety. A sign ordinance narrowly tailored to the challenges of protecting the safety of pedestrians, drivers, and passengers-such as warning signs marking hazards on private property, signs directing traffic, or street numbers associated with private houses-well might survive strict scrutiny. The signs at issue in this case, including political and ideological signs and signs for events, are far removed from those purposes. As discussed above, they are facially content based and are neither justified by traditional safety concerns nor narrowly tailored.

* * *

*2233 We reverse the judgment of the Court of Appeals and remand the case for proceedings consistent with this opinion.

It is so ordered.

Justice ALITO, with whom Justice KENNEDYand Justice SOTOMAYORjoin, concurring.

I join the opinion of the Court but add a few words of further explanation.

As the Court holds, what we have termed "content-based" laws must satisfy strict scrutiny. Content-based laws merit this protection because they present, albeit sometimes in a subtler form, the same dangers as laws that regulate speech based on viewpoint. Limiting speech based on its "topic" or "subject" favors those who do not want to disturb the status quo. Such regulations may interfere with democratic self-government and the search for truth. See Consolidated Edison Co. of N.Y. v. Public Serv. Comm'n of N. Y., 447 U.S. 530 , 537, 100 S.Ct. 2326 , 65 L.Ed.2d 319 (1980).

As the Court shows, the regulations at issue in this case are replete with content-based distinctions, and as a result they must satisfy strict scrutiny. This does not mean, however, that municipalities are powerless to enact and enforce reasonable sign regulations. I will not attempt to provide anything like a comprehensive list, but here are some rules that would not be content based:

Rules regulating the size of signs. These rules may distinguish among signs based on any content-neutral criteria, including any relevant criteria listed below.

Rules regulating the locations in which signs may be placed. These rules may distinguish between free-standing signs and those attached to buildings.

Rules distinguishing between lighted and unlighted signs.

Rules distinguishing between signs with fixed messages and electronic signs with messages that change.

Rules that distinguish between the placement of signs on private and public property.

Rules distinguishing between the placement of signs on commercial and residential property.

Rules distinguishing between on-premises and off-premises signs.

Rules restricting the total number of signs allowed per mile of roadway.

Rules imposing time restrictions on signs advertising a one-time event. Rules of this nature do not discriminate based on topic or subject and are akin to rules restricting the times within which oral speech or music is allowed. *

In addition to regulating signs put up by private actors, government entities may also erect their own signs consistent with the principles that allow governmental speech. See Pleasant Grove City v. Summum, 555 U.S. 460 , 467-469, 129 S.Ct. 1125 , 172 L.Ed.2d 853 (2009). They may put up all manner of signs to promote safety, as well as directional signs and signs pointing out historic sites and scenic spots.

Properly understood, today's decision will not prevent cities from regulating signs in a way that fully protects public *2234 safety and serves legitimate esthetic objectives.

Justice BREYER, concurring in the judgment.

I join Justice KAGAN's separate opinion. Like Justice KAGAN I believe that categories alone cannot satisfactorily resolve the legal problem before us. The First Amendment requires greater judicial sensitivity both to the Amendment's expressive objectives and to the public's legitimate need for regulation than a simple recitation of categories, such as "content discrimination" and "strict scrutiny," would permit. In my view, the category "content discrimination" is better considered in many contexts, including here, as a rule of thumb, rather than as an automatic "strict scrutiny" trigger, leading to almost certain legal condemnation.

To use content discrimination to trigger strict scrutiny sometimes makes perfect sense. There are cases in which the Court has found content discrimination an unconstitutional method for suppressing a viewpoint. E.g., Rosenberger v. Rector and Visitors of Univ. of Va., 515 U.S. 819 , 828-829, 115 S.Ct. 2510 , 132 L.Ed.2d 700 (1995); see also Boos v. Barry, 485 U.S. 312 , 318-319, 108 S.Ct. 1157 , 99 L.Ed.2d 333 (1988)(plurality opinion) (applying strict scrutiny where the line between subject matter and viewpoint was not obvious). And there are cases where the Court has found content discrimination to reveal that rules governing a traditional public forum are, in fact, not a neutral way of fairly managing the forum in the interest of all speakers. Police Dept. of Chicago v. Mosley, 408 U.S. 92 , 96, 92 S.Ct. 2286 , 33 L.Ed.2d 212 (1972)("Once a forum is opened up to assembly or speaking by some groups, government may not prohibit others from assembling or speaking on the basis of what they intend to say"). In these types of cases, strict scrutiny is often appropriate, and content discrimination has thus served a useful purpose.

But content discrimination, while helping courts to identify unconstitutional suppression of expression, cannot and should not always trigger strict scrutiny. To say that it is not an automatic "strict scrutiny" trigger is not to argue against that concept's use. I readily concede, for example, that content discrimination, as a conceptual tool, can sometimes reveal weaknesses in the government's rationale for a rule that limits speech. If, for example, a city looks to litter prevention as the rationale for a prohibition against placing newsracks dispensing free advertisements on public property, why does it exempt other newsracks causing similar litter? Cf. Cincinnati v. Discovery Network, Inc., 507 U.S. 410 , 113 S.Ct. 1505 , 123 L.Ed.2d 99 (1993). I also concede that, whenever government disfavors one kind of speech, it places that speech at a disadvantage, potentially interfering with the free marketplace of ideas and with an individual's ability to express thoughts and ideas that can help that individual determine the kind of society in which he wishes to live, help shape that society, and help define his place within it.

Nonetheless, in these latter instances to use the presence of content discrimination automatically to trigger strict scrutiny and thereby call into play a strong presumption against constitutionality goes too far. That is because virtually all government activities involve speech, many of which involve the regulation of speech. Regulatory programs almost always require content discrimination. And to hold that such content discrimination triggers strict scrutiny is to write a recipe for judicial management of ordinary government regulatory activity.

Consider a few examples of speech regulated by government that inevitably involve *2235 content discrimination, but where a strong presumption against constitutionality has no place. Consider governmental regulation of securities, e.g., 15 U.S.C. § 78 l (requirements for content that must be included in a registration statement); of energy conservation labeling-practices, e.g., 42 U.S.C. § 6294 (requirements for content that must be included on labels of certain consumer electronics); of prescription drugs, e.g., 21 U.S.C. § 353 (b)(4)(A)(requiring a prescription drug label to bear the symbol "Rx only"); of doctor-patient confidentiality, e.g., 38 U.S.C. § 7332 (requiring confidentiality of certain medical records, but allowing a physician to disclose that the patient has HIV to the patient's spouse or sexual partner); of income tax statements, e.g., 26 U.S.C. § 6039F(requiring taxpayers to furnish information about foreign gifts received if the aggregate amount exceeds $10,000); of commercial airplane briefings, e.g., 14 CFR § 136.7 (2015)(requiring pilots to ensure that each passenger has been briefed on flight procedures, such as seatbelt fastening); of signs at petting zoos, e.g., N.Y. Gen. Bus. Law Ann. § 399 -ff(3) (West Cum. Supp. 2015) (requiring petting zoos to post a sign at every exit " 'strongly recommend[ing] that persons wash their hands upon exiting the petting zoo area' "); and so on.

Nor can the majority avoid the application of strict scrutiny to all sorts of justifiable governmental regulations by relying on this Court's many subcategories and exceptions to the rule. The Court has said, for example, that we should apply less strict standards to "commercial speech." Central Hudson Gas & Elec. Corp. v. Public Service Comm'n of N. Y., 447 U.S. 557 , 562-563, 100 S.Ct. 2343 , 65 L.Ed.2d 341 (1980). But I have great concern that many justifiable instances of "content-based" regulation are noncommercial. And, worse than that, the Court has applied the heightened "strict scrutiny" standard even in cases where the less stringent "commercial speech" standard was appropriate. See Sorrell v. IMS Health Inc., 564 U.S. ----, ----, 131 S.Ct. 2653 , 2664, 180 L.Ed.2d 544 (2011)(BREYER, J., dissenting). The Court has also said that "government speech" escapes First Amendment strictures. See Rust v. Sullivan, 500 U.S. 173 , 193-194, 111 S.Ct. 1759 , 114 L.Ed.2d 233 (1991). But regulated speech is typically private speech, not government speech. Further, the Court has said that, "[w]hen the basis for the content discrimination consists entirely of the very reason the entire class of speech at issue is proscribable, no significant danger of idea or viewpoint discrimination exists." R.A.V. v. St. Paul, 505 U.S. 377 , 388, 112 S.Ct. 2538 , 120 L.Ed.2d 305 (1992). But this exception accounts for only a few of the instances in which content discrimination is readily justifiable.

I recognize that the Court could escape the problem by watering down the force of the presumption against constitutionality that "strict scrutiny" normally carries with it. But, in my view, doing so will weaken the First Amendment's protection in instances where "strict scrutiny" should apply in full force.

The better approach is to generally treat content discrimination as a strong reason weighing against the constitutionality of a rule where a traditional public forum, or where viewpoint discrimination, is threatened, but elsewhere treat it as a rule of thumb, finding it a helpful, but not determinative legal tool, in an appropriate case, to determine the strength of a justification. I would use content discrimination as a supplement to a more basic analysis, which, tracking most of our First Amendment cases, asks whether the regulation at issue works harm to First Amendment interests that is disproportionate in light of *2236 the relevant regulatory objectives. Answering this question requires examining the seriousness of the harm to speech, the importance of the countervailing objectives, the extent to which the law will achieve those objectives, and whether there are other, less restrictive ways of doing so. See, e.g., United States v. Alvarez, 567 U.S. ----, ---- - ----, 132 S.Ct. 2537 , 2551-2553, 183 L.Ed.2d 574 (2012)(BREYER, J., concurring in judgment); Nixon v. Shrink Missouri Government PAC, 528 U.S. 377 , 400-403, 120 S.Ct. 897 , 145 L.Ed.2d 886 (2000)(BREYER, J., concurring). Admittedly, this approach does not have the simplicity of a mechanical use of categories. But it does permit the government to regulate speech in numerous instances where the voters have authorized the government to regulate and where courts should hesitate to substitute judicial judgment for that of administrators.

Here, regulation of signage along the roadside, for purposes of safety and beautification is at issue. There is no traditional public forum nor do I find any general effort to censor a particular viewpoint. Consequently, the specific regulation at issue does not warrant "strict scrutiny." Nonetheless, for the reasons that Justice KAGAN sets forth, I believe that the Town of Gilbert's regulatory rules violate the First Amendment. I consequently concur in the Court's judgment only.

Justice KAGAN, with whom Justice GINSBURGand Justice BREYERjoin, concurring in the judgment.

Countless cities and towns across America have adopted ordinances regulating the posting of signs, while exempting certain categories of signs based on their subject matter. For example, some municipalities generally prohibit illuminated signs in residential neighborhoods, but lift that ban for signs that identify the address of a home or the name of its owner or occupant. See, e.g., City of Truth or Consequences, N. M., Code of Ordinances, ch. 16, Art. XIII, §§ 11-13-2.3, 11-13-2.9(H)(4) (2014). In other municipalities, safety signs such as "Blind Pedestrian Crossing" and "Hidden Driveway" can be posted without a permit, even as other permanent signs require one. See, e.g., Code of Athens-Clarke County, Ga., Pt. III, § 7-4-7(1) (1993). Elsewhere, historic site markers-for example, "George Washington Slept Here"-are also exempt from general regulations. See, e.g., Dover, Del., Code of Ordinances, Pt. II, App. B, Art. 5, § 4.5(F) (2012). And similarly, the federal Highway Beautification Act limits signs along interstate highways unless, for instance, they direct travelers to "scenic and historical attractions" or advertise free coffee. See 23 U.S.C. §§ 131 (b), (c)(1), (c)(5).

Given the Court's analysis, many sign ordinances of that kind are now in jeopardy. See ante, at 2231 (acknowledging that "entirely reasonable" sign laws "will sometimes be struck down" under its approach (internal quotation marks omitted)). Says the majority: When laws "single[ ] out specific subject matter," they are "facially content based"; and when they are facially content based, they are automatically subject to strict scrutiny. Ante, at 2230, 2232 - 2233. And although the majority holds out hope that some sign laws with subject-matter exemptions "might survive" that stringent review, ante, at 2232 - 2233, the likelihood is that most will be struck down. After all, it is the "rare case[ ] in which a speech restriction withstands strict scrutiny." Williams-Yulee v. Florida Bar, 575 U.S. ----, ----, 135 S.Ct. 1656 , 1666, ---L.Ed.2d ---- (2015). To clear that high bar, the government must show that a content-based distinction "is necessary to serve a compelling state interest and is narrowly drawn to achieve that end." Arkansas Writers' Project, Inc.

*2237 v. Ragland, 481 U.S. 221 , 231, 107 S.Ct. 1722 , 95 L.Ed.2d 209 (1987). So on the majority's view, courts would have to determine that a town has a compelling interest in informing passersby where George Washington slept. And likewise, courts would have to find that a town has no other way to prevent hidden-driveway mishaps than by specially treating hidden-driveway signs. (Well-placed speed bumps? Lower speed limits? Or how about just a ban on hidden driveways?) The consequence-unless courts water down strict scrutiny to something unrecognizable-is that our communities will find themselves in an unenviable bind: They will have to either repeal the exemptions that allow for helpful signs on streets and sidewalks, or else lift their sign restrictions altogether and resign themselves to the resulting clutter. *

Although the majority insists that applying strict scrutiny to all such ordinances is "essential" to protecting First Amendment freedoms, ante, at 2231, I find it challenging to understand why that is so. This Court's decisions articulate two important and related reasons for subjecting content-based speech regulations to the most exacting standard of review. The first is "to preserve an uninhibited marketplace of ideas in which truth will ultimately prevail." McCullen v. Coakley, 573 U.S. ----, ---- - ----, 134 S.Ct. 2518 , 2529, 189 L.Ed.2d 502 (2014)(internal quotation marks omitted). The second is to ensure that the government has not regulated speech "based on hostility-or favoritism-towards the underlying message expressed." R.A.V. v. St. Paul, 505 U.S. 377 , 386, 112 S.Ct. 2538 , 120 L.Ed.2d 305 (1992). Yet the subject-matter exemptions included in many sign ordinances do not implicate those concerns. Allowing residents, say, to install a light bulb over "name and address" signs but no others does not distort the marketplace of ideas. Nor does that different treatment give rise to an inference of impermissible government motive.

We apply strict scrutiny to facially content-based regulations of speech, in keeping with the rationales just described, when there is any "realistic possibility that official suppression of ideas is afoot." Davenport v. Washington Ed. Assn., 551 U.S. 177 , 189, 127 S.Ct. 2372 , 168 L.Ed.2d 71 (2007)(quoting R. A.V., 505 U.S., at 390 , 112 S.Ct. 2538 ). That is always the case when the regulation facially differentiates on the basis of viewpoint. See Rosenberger v. Rector and Visitors of Univ. of Va., 515 U.S. 819 , 829, 115 S.Ct. 2510 , 132 L.Ed.2d 700 (1995). It is also the case (except in non-public or limited public forums) when a law restricts "discussion of an entire topic" in public debate. Consolidated Edison Co. of N.Y. v. Public Serv. Comm'n of N. Y., 447 U.S. 530 , 537, 539-540, 100 S.Ct. 2326 , 65 L.Ed.2d 319 (1980)(invalidating a limitation on speech about nuclear power). We have stated that "[i]f the marketplace of ideas is to remain free and open, governments must not be allowed to choose 'which issues are worth discussing or debating.' " Id., at 537-538, 100 S.Ct. 2326 (quoting Police Dept. of *2238 Chicago v. Mosley, 408 U.S. 92 , 96, 92 S.Ct. 2286 , 33 L.Ed.2d 212 (1972)). And we have recognized that such subject-matter restrictions, even though viewpoint-neutral on their face, may "suggest[ ] an attempt to give one side of a debatable public question an advantage in expressing its views to the people." First Nat. Bank of Boston v. Bellotti, 435 U.S. 765 , 785, 98 S.Ct. 1407 , 55 L.Ed.2d 707 (1978); accord, ante, at 2233 (ALITO, J., concurring) (limiting all speech on one topic "favors those who do not want to disturb the status quo"). Subject-matter regulation, in other words, may have the intent or effect of favoring some ideas over others. When that is realistically possible-when the restriction "raises the specter that the Government may effectively drive certain ideas or viewpoints from the marketplace"-we insist that the law pass the most demanding constitutional test. R.A.V., 505 U.S., at 387 , 112 S.Ct. 2538 (quoting Simon & Schuster, Inc. v. Members of N.Y. State Crime Victims Bd., 502 U.S. 105 , 116, 112 S.Ct. 501 , 116 L.Ed.2d 476 (1991)).

But when that is not realistically possible, we may do well to relax our guard so that "entirely reasonable" laws imperiled by strict scrutiny can survive. Ante, at 2231. This point is by no means new. Our concern with content-based regulation arises from the fear that the government will skew the public's debate of ideas-so when "that risk is inconsequential, ... strict scrutiny is unwarranted." Davenport, 551 U.S., at 188 , 127 S.Ct. 2372 ; see R.A.V., 505 U.S., at 388 , 112 S.Ct. 2538 (approving certain content-based distinctions when there is "no significant danger of idea or viewpoint discrimination"). To do its intended work, of course, the category of content-based regulation triggering strict scrutiny must sweep more broadly than the actual harm; that category exists to create a buffer zone guaranteeing that the government cannot favor or disfavor certain viewpoints. But that buffer zone need not extend forever. We can administer our content-regulation doctrine with a dose of common sense, so as to leave standing laws that in no way implicate its intended function.

And indeed we have done just that: Our cases have been far less rigid than the majority admits in applying strict scrutiny to facially content-based laws-including in cases just like this one. See Davenport, 551 U.S., at 188 , 127 S.Ct. 2372 (noting that "we have identified numerous situations in which [the] risk" attached to content-based laws is "attenuated"). In Members of City Council of Los Angeles v. Taxpayers for Vincent, 466 U.S. 789 , 104 S.Ct. 2118 , 80 L.Ed.2d 772 (1984), the Court declined to apply strict scrutiny to a municipal ordinance that exempted address numbers and markers commemorating "historical, cultural, or artistic event[s]" from a generally applicable limit on sidewalk signs. Id., at 792, n. 1, 104 S.Ct. 2118 (listing exemptions); see id., at 804-810, 104 S.Ct. 2118 (upholding ordinance under intermediate scrutiny). After all, we explained, the law's enactment and enforcement revealed "not even a hint of bias or censorship." Id., at 804, 104 S.Ct. 2118 ; see also Renton v. Playtime Theatres, Inc., 475 U.S. 41 , 48, 106 S.Ct. 925 , 89 L.Ed.2d 29 (1986)(applying intermediate scrutiny to a zoning law that facially distinguished among movie theaters based on content because it was "designed to prevent crime, protect the city's retail trade, [and] maintain property values ..., not to suppress the expression of unpopular views"). And another decision involving a similar law provides an alternative model. In City of Ladue v. Gilleo, 512 U.S. 43 , 114 S.Ct. 2038 , 129 L.Ed.2d 36 (1994), the Court assumed arguendo that a sign ordinance's exceptions for address *2239 signs, safety signs, and for-sale signs in residential areas did not trigger strict scrutiny. See id., at 46-47, and n. 6, 114 S.Ct. 2038 (listing exemptions); id., at 53, 114 S.Ct. 2038 (noting this assumption). We did not need to, and so did not, decide the level-of-scrutiny question because the law's breadth made it unconstitutional under any standard.

The majority could easily have taken Ladue 's tack here. The Town of Gilbert's defense of its sign ordinance-most notably, the law's distinctions between directional signs and others-does not pass strict scrutiny, or intermediate scrutiny, or even the laugh test. See ante, at 2231 - 2232 (discussing those distinctions). The Town, for example, provides no reason at all for prohibiting more than four directional signs on a property while placing no limits on the number of other types of signs. See Gilbert, Ariz., Land Development Code, ch. I, §§ 4.402(J), (P)(2) (2014). Similarly, the Town offers no coherent justification for restricting the size of directional signs to 6 square feet while allowing other signs to reach 20 square feet. See §§ 4.402(J), (P)(1). The best the Town could come up with at oral argument was that directional signs "need to be smaller because they need to guide travelers along a route." Tr. of Oral Arg. 40. Why exactly a smaller sign better helps travelers get to where they are going is left a mystery. The absence of any sensible basis for these and other distinctions dooms the Town's ordinance under even the intermediate scrutiny that the Court typically applies to "time, place, or manner" speech regulations. Accordingly, there is no need to decide in this case whether strict scrutiny applies to every sign ordinance in every town across this country containing a subject-matter exemption.

I suspect this Court and others will regret the majority's insistence today on answering that question in the affirmative. As the years go by, courts will discover that thousands of towns have such ordinances, many of them "entirely reasonable." Ante, at 2231. And as the challenges to them mount, courts will have to invalidate one after the other. (This Court may soon find itself a veritable Supreme Board of Sign Review.) And courts will strike down those democratically enacted local laws even though no one-certainly not the majority-has ever explained why the vindication of First Amendment values requires that result. Because I see no reason why such an easy case calls for us to cast a constitutional pall on reasonable regulations quite unlike the law before us, I concur only in the judgment.
