On January 20, 1978, Eugene Robinson drove his pickup truck to Tom Marks’s Garage, a repair garage owned by Tom Marks. Robinson went there to pick up a hydraulic jack. As Robinson and Marks were loading the jack into the truck, Robinson slipped on some grease on the garage floor. He fell and suffered a back injury.

Eugene and Edith Robinson sued Tom Marks for negligence. Mr. Marks’s insurer, Ohio Casualty Insurance Group, brought this action for declaratory relief to establish that Mr. Marks is also an insured under Mr. Robinson’s automobile policy with Riverside Insurance Company, a member of the Transamerica Group.1 Under Ohio Casualty’s theory, if Mr. Marks were an insured under the Transamerica policy, then Ohio Casualty would not be solely liable for Mr. Robinson’s injuries. The Monroe County Circuit Court granted summary judgment for Ohio Casualty on January 6, 1982. Transamerica appeals.

In this case we are faced with the confusing task of determining whether the noninjured party (Mr. Marks) to the accident would be covered by the injured party’s insurance policy (Mr. Robinson’s policy with Transamerica). Transamerica raises four issues in this regard, which we now consider.

*141I

Transamerica first argues that Marks was not "using” the truck and therefore is not a defined insured under the Transamerica policy. In Section I of the policy Transamerica agrees to pay for injuries "arising out of the ownership, maintenance, or use of the insured automobile, including the loading and unloading thereof’. It is nowhere required in the policy that the "user” also be the driver, and case law does not impose such a construction. See, e.g., BASF Wyandotte Corp v Transport Ins Co, 523 F Supp 515 (ED Mich, 1981). The clear wording of the Transamerica policy designates Mr. Marks as an "insured” while he is loading or unloading the insured vehicle. We therefore find no error in the trial court’s conclusion that Mr. Marks was "using” the vehicle when Mr. Robinson was injured.

II

Transamerica next argues that Mr. Marks was specifically excluded from coverage because he is a "person operating a repair shop”. Section III of the policy provides that:

"The insurance with respect to any person or organization other than the Named Insured or spouse does not apply:

"(1) to any person or organization or to any agent or employee thereof, operating an automobile sales agency, repair shop, service station, storage garage or public parking place, with respect to any occurrence arising out of the operation thereof * * *.”

Ohio Casualty argues that Mr. Marks did not operate "an automobile sales agency [or] repair shop” under the policy because he repaired trucks *142and trailers, not automobiles. Assuming for the sake of argument that only "automobile” repair shops are excluded from coverage, we believe Mr. Marks’s business fits within the exclusionary language of Transamerica’s policy.2 We conclude this because of the policy’s definition of "automobile” in Section IV:

"Except where specifically stated to the contrary, the word 'automobile’ wherever used shall include its equipment and other equipment permanently attached thereto and shall mean the described automobile, a land motor vehicle, trailer, semi-trailer or house-trailer, not operated on rails or crawler-treads, but, except with respect to Section (2) Coverage C Medical Payments, none of the foregoing shall include a motorcycle unless specifically described in the Policy, and except while actually upon public roads, does not mean a farm type tractor or equipment * *

A truck is a "land motor vehicle”, MCL 475.1; MSA 22.531, and is nowhere excluded by the policy from the "automobile” definition. In fact, the insured "automobile” in this case is a truck. The trial court found, though, that Mr. Marks was not excluded under Section III. This finding is clearly erroneous and merits reversal.

Ill

Transamerica raises as its third issue the argument that Mr. Marks was not a named insured *143under the "use of other automobiles” section of the Transamerica policy. We are unable to consider this issue because it was not addressed by the trial court.

IV

In its final issue, Transamerica argues that, if Tom Marks is an insured under the Transamerica policy, Ohio Casualty would still be obligated to pay as the primary insurer of the Marks premises under Ohio Casualty’s policy. That policy states:

"The insurance afforded by this policy is primary insurance, except when stated to apply in excess of or contingent upon the absence of other insurance. When this insurance is primary and the insured has other insurance which is stated to be applicable to the loss on an excess or contingent basis, the amount of the company’s liability under this policy shall not be reduced by the existence of such other insurance.

"When both this insurance and other insurance apply to the loss on the same basis, whether primary, excess or contingent, the company shall not be liable under this policy for a greater proportion of the loss than that stated in the applicable contribution provision below * # * »

Transamerica argues that the Ohio Casualty policy establishes primary liability by Ohio Casualty to the policy limit of $100,000. Ohio Casualty argues that the Transamerica policy applies "on the same basis”, and therefore Transamerica has pro-rata liability. As discussed in the second issue, the Transamerica policy excludes Mr. Marks as the operator of a repair shop. The Transamerica policy therefore does not apply "on the same basis” as the Ohio Casualty policy, and Transamerica has no pro-rata liability.

*144V

As mentioned earlier, this case involves a determination of whether the noninjured party to the accident would be covered by the injured party’s insurance policy. Throughout these proceedings the parties seem to have assumed that the Robin-sons have a cause of action against the garage owner’s insurer, Ohio Casualty.3 It has become apparent in our treatment of the issues, though, that Mr. Robinson’s injury arose out of the use of his vehicle as that term is used in the no-fault act. MCL 50).3105(1); MSA 24.13105(1). See MCL 500.3106(c); MSA 24.13106(c); Nickerson v Citizens Mutual Ins Co, 393 Mich 324, 331; 224 NW2d 896 (1975). It would be contrary to the strong public policy behind the no-fault act if Transamerica were completely absolved of liability for injuries arising out of the use of an automobile it insures.

The trial court and Ohio Casualty in its brief cite 16 Couch, Insurance, 2d, § 62:1 as supporting pro rata liability among insurers. The two Michigan cases cited in Couch, however, do not support pro rata liability. In Werner v Travelers Indemnity Co, 55 Mich App 390; 222 NW2d 254 (1974), the plaintiffs decedent was killed in an accident involving an uninsured motorist. The plaintiffs decedent and the owner-driver of the car she was riding in were insured by different companies. Despite a "pro rata” clause in the driver’s policy, the Court held that his policy was the primary policy for the passenger’s representative to look to for recovery. The passenger’s policy was secondary *145and would pay only for the excess over the primary policy’s limit. In Hartman v Ins Co of North America, 106 Mich App 731; 308 NW2d 625 (1981), lv den 414 Mich 890 (1982), a no-fault case, the Court established a "priority” of claims for injuries to a bicyclist in a bicycle-automobile accident. The bicyclist’s no-fault carrier, if any, would be primarily liable, followed by the insurer of a "relative domiciled in the same household” and, finally, the insurer holding the policy on the automobile involved in the accident. See also Underhill v Safeco Ins Co, 407 Mich 175, 182; 284 NW2d 463 (1979) (motorcyclist). Neither case stands for pro rata liability — in fact, in stark contrast, they stand for a system of priorities involving primary and secondary liability.

The difficulty which now arises involves the conflict between Mr. Robinson’s no-fault policy on his automobile and Mr. Marks’s garage policy. The no-fault act was intended to abolish, in part, tort determinations of fault. Shavers v Attorney General, 402 Mich 554, 579; 267 NW2d 72 (1978). By way of analogy only, two panels of this Court have held that the no-fault act’s abolition of tort liability is strong enough to overcome the public policy behind the garage keeper’s liability act’s rebuttable presumption of negligence when a vehicle is returned damaged. Buckeye Union Ins Co v Johnson, 108 Mich App 46; 310 NW2d 268 (1981), lv den 414 Mich 873 (1982); Liberty Mutual Ins Co v Ins Co of North America, 117 Mich App 197; 323 NW2d 650 (1982). See MCL 256.541; MSA 9.1721.4 *146On remand the trial court should give appropriate consideration to this issue and determine whether Mr. Robinson’s primary source of recovery is his own no-fault carrier.

Based on the second issue, we reverse summary judgment and remand for further proceedings.

(concurring in part and dissenting in part). I agree with the majority that Marks, as a person operating a repair shop, was excluded from coverage under Robinson’s policy with Transamerica. I respectfully dissent from the majority’s directions for remand.

The majority has ordered that, on remand, the circuit court shall determine whether Robinson’s primary source of recovery is his own no-fault automobile insurance carrier. I have four objections to this result.

(1) No such issue was raised by the parties.

(2) In a separate action, Robinson is suing Marks for negligence. In this action, the Ohio Casualty Insurance Company, Marks’s garage keeper’s premises liability insurance carrier, sought a declaratory judgment that Marks was an "insured” under Robinson’s no-fault automobile insurance policy and that Transamerica, the no-fault carrier, had a duty to defend Marks and aiford him coverage in the action between Robinson and Marks. The issue raised by the majority is outside the *147scope of this action and belongs in the action between Robinson and Marks.

(3) Robinson’s no-fault automobile insurance carrier is not his primary source of recovery if Robinson’s action against Marks falls within one of the exceptions to the abolition of tort liability stated in MCL 500.3135(2); MSA 24.13135(2).

(4) In Citizens Ins Co of America v Tuttle, 411 Mich 536; 309 NW2d 174 (1981), the Court held that the no-fault act did not abolish the tort liability of a defendant whose wrongful act did not involve his ownership, maintenance, or use of a motor vehicle, even though the action may have also arisen out of the plaintiffs ownership, maintenance, or use of a motor vehicle. Here, Robinson has represented to both this Court and the circuit court that his complaint against Marks alleges that the accident was caused by Robinson’s slipping on grease on the floor of Marks’s garage. If this is, in fact, the causal mechanism on which Robinson relies in his action against Marks, then Robinson’s action against Marks falls within the rule stated in Tuttle, and Marks’s loading of Robinson’s motor vehicle at the time of the accident is merely a fortuitous coincidence of no relevance. Robinson’s no-fault automobile insurance carrier is not his primary source of recovery if Tuttle allows him to recover damages in a negligence action against Marks.

Because this case was before the circuit court on cross motions for summary judgment, I would reverse and remand the case for entry of an order of summary judgment for Transamerica.
