Affirmed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

Stanley Arnold Greene appeals his conviction following a conditional guilty plea to possession of a firearm by a convicted felon, in violation of 18 U.S.C. § 922(g)(1) (2006). On appeal, Greene contends that the district court erred in denying his motion to suppress the gun officers found in the trunk of his vehicle. Finding no error, we affirm.

*304 In reviewing the district court’s denial of a motion to suppress, “[w]e review the district court’s legal determinations de novo and its factual determinations for clear error.” United States v. Kelly, 592 F.3d 586, 589 (4th Cir. 2010). When the district court has denied a suppression motion, “we construe the evidence in the light most favorable to the government.” Id.

Greene first contends that the vehicle search was invalid because it was not incident to a lawful arrest. While Greene’s factual premise is accurate, his conclusion is not. 1 There is a well-established exception to the warrant requirement for automobile searches. Under this exception, “[i]f a car is readily mobile and probable cause exists to believe it contains contraband, the Fourth Amendment thus permits police to search the vehicle without more.” Pennsylvania v. Labron, 518 U.S. 938, 940, 116 S.Ct. 2485, 135 L.Ed.2d 1031 (1996) (citation omitted). Further, “it is well settled that a ‘positive alert’ from a drug detection dog, in and of itself, provides probable cause to search a vehicle.” United States v. Branch, 537 F.3d 328, 340 n. 2 (4th Cir. 2008).

Greene’s second argument&emdash;that the search of the trunk was outside the scope of a warrantless search&emdash;is likewise merit-less. See Kelly, 592 F.3d at 589-90 (“The scope of a search pursuant to [the automobile] exception is as broad as a magistrate could authorize. Thus, once police have probable cause, they may search ‘every part of the vehicle and its contents that may conceal the object of the search.’ ”) (quoting United States v. Ross, 456 U.S. 798, 825, 102 S.Ct. 2157, 72 L.Ed.2d 572 (1982) (citation omitted)).

Accordingly, we affirm the district court’s judgment. 2 We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

AFFIRMED.
