In this declaratory action for determination of insurance coverage, defendant Zurich-American Insurance Group appeals as of right the trial court’s March 31, 1994, grant of summary disposition against it and in favor of plaintiff. Plaintiff cross appeals the court’s entry of summary disposition in favor of defendant Liberty Mutual Insurance Company. We affirm.
Plaintiff is a truck driver who owned a 1987 International Cab tractor (hereinafter “truck”) that was leased to B & W Cartage Company, a carrier operating under a permit issued by the Interstate Commerce Commission. The lease provided that plaintiff rented the truck “complete with drivers, to B & W for use in loading and transporting such property as B & W may require.”
On May 26, 1992, plaintiff used the truck to make deliveries that were assigned to him by B & W. His *484last delivery was to Guardian Glass. According to his deposition, after dropping off a trailer there, he considered the day’s work over. Because the delivery to Guardian Glass was a one-way haul, plaintiff explained, he “never got paid a dime for going no place after [he] left Guardian.” He drove the truck to a restaurant for dinner, ate there, and left. While plaintiff was en route to B & W, at approximately 6:30 P.M., the truck collided with a vehicle driven by defendant Beverly McConnell.
After the accident, plaintiff went to B & W’s yard, parked the truck, checked for messages, and went home in his pickup truck. Plaintiff had no obligation to return to B & W after the delivery. He knew that the dispatcher’s office would be closed. (The normal hours of operation were 6:00 a.m. to 6:30 P.M.) Although plaintiff routinely parked the truck at the B & W lot because he had no other place to park it, he was not required to do so.
In accordance with the terms of the lease between plaintiff and B & W, both plaintiff and B & W insured the truck. Plaintiff had a “bobtail” insurance policy with Zurich, and B & W insured the truck through Liberty. After McConnell sued plaintiff for personal injuries sustained in the accident, plaintiff brought this action against Zurich and Liberty for a declaration of his rights under the two insurance policies.
Following cross-motions for summary disposition, the trial court ruled that the policy from Zurich, but not Liberty, provided coverage.
The Zurich policy contained a provision that excluded coverage “[w]hile the automobile is being used in the business of any person or organization to whom the automobile is rented.” The issue in this *485case is whether this exclusion applies, specifically, whether the truck was being used “in the business” of B & W at the time of the accident.1
Zurich argues that coverage was excluded because at the time of the accident plaintiff was furthering the commercial interests of B & W:
Although parking his truck at the yard was coincidentally a matter of convenience for Engle, it also benefited B & W because it permitted the truck to be ready for use at any time. The fact that Engle stopped at the yard every night also allowed for the two way exchange of information between trucker and carrier, a fact which also indicates a business purpose.
Zurich primarily relies on St Paul Fire & Marine Ins Co v Frankart, 69 Ill 2d 209; 13 Ill Dec 31; 370 NE2d 1058 (1977). In that case, Frankart leased his truck and trailer to Wilson Freight Company. He was involved in an accident after he completed a delivery for Wilson and was heading in the direction of his home with an empty trailer. The court concluded that a clause identical to the provision at issue in this case excluded coverage.
Wilson’s failure to have another assignment for Frankart at its Illinois terminal did not terminate its “exclusive possession, control, responsibility and use” of Frankart’s tractor-trailer provided under the lease. It is the nature of Wilson’s business that its owner-drivers will be relieved of a *486load at a point of delivery, and that, unless another load can be picked up on the return trip, the owner-drivers must make their return trip pulling an empty trailer. As Wilson’s vice president conceded, the original assignment does not terminate at the point of delivery. We find that it continues at least until the owner-driver returns to the point where the haul originated ..., to the terminal from which the haul was assigned ... , or to the owner-driver’s home terminal from which he customarily obtained his next assignment. [Id. At 218.]
In this case, the trial court rejected Zurich’s arguments and determined that the exclusion did not apply. The court noted that plaintiff was not returning to the terminal to drop off property belonging to B & W, that he was not being paid, that he had made his final delivery, and that he was not under any directive to return to the terminal. As for the significance of the plaintiff’s returning to the terminal to park the truck and get his pickup truck, the court stated:
[T]he purpose of his return to the terminal, to park his truck, was entirely a personal matter. B and W did not exercise any control over where trucks were parked when not in use for B and W. Nor was B and W obligated to secure for its truckers a place to park. Rather B and W permitted Plaintiff as well as other truckers to park their rigs at its terminal as a convenience to them.
The courts of this state have not issued any published decisions discussing whether an exclusionary clause similar to the one at issue applies when the truck is being used after the driver has completed assigned deliveries.2 Courts of foreign jurisdictions *487confronted with similar facts and exclusions have reached different conclusions. See Frankart, supra; McLean Trucking Co v Occidental Fire & Casualty Co, 72 NC App 285; 324 SE2d 633 (1985); Liberty Mutual Ins Co v Connecticut Indemnity Co, 55 F3d 1333 (CA 7, 1995); Acceptance Ins Co v Canter, 927 F2d 1026 (CA 8, 1991), and cases cited therein.
We conclude that the exclusion is subject to more than one reasonable interpretation and construe it against Zurich. A provision is said to be ambiguous when its words may reasonably be understood in different ways. Clevenger v Allstate Ins Co, 443 Mich 646, 654; 505 NW2d 553 (1993), quoting Raska v Farm Bureau Mutual Ins Co of Michigan, 412 Mich 355, 362; 314 NW2d 440 (1982). The view of the court in Frankart, essentially, that a vehicle is being used in the business of the carrier during the return trip, is a reasonable inteipretation of the exclusionary provision. However, the view of the trial court is also a reasonable inteipretation. Therefore, the provision is ambiguous, and must be construed against the insurer and in favor of coverage. Although Zurich may decide to include the Frankart definition of “in the business” in the policy, we do not believe it is appropriate for this Court to impose the definition by way of judicial interpretation.
*488On cross appeal, plaintiff contends that if this Court reverses the trial court’s grant of summary disposition against Zurich, that it must also reverse the denial of summary disposition against Liberty. We recognize that the extent of the insurers’ obligations is governed by the terms of their respective policies. Zurich-American Ins Co v Amerisure Ins Co, 215 Mich App 526; 547 NW2d 52 (1996). However, because plaintiff requests review of this aspect of the court’s decision only if we reverse summary disposition against Zurich, we need not address the issues presented in the cross appeal.
Affirmed.
Zurich’s sole issue on appeal according to its statement of questions presented is:
Whether the trial court properly granted summary disposition on THE ISSUE OF WHETHER PLAINTIFF WAS “IN THE BUSINESS” OF ITS LESSEE AT THE TIME OF THE ACCIDENT, AND THEREFORE WITHIN THE EXCLUSION OF THE NONTRUCKING POLICY?
We note that in Zurich Ins Co v Rombough, 384 Mich 228; 180 NW2d 775 (1970), the Court held that a policy containing a similar clause, “in any business,” was ambiguous. However, the Court stated that it was the *487relationship between the exclusion and the clause relating to the insurer’s duty to defend that created the ambiguity. Id. at 232. The Court did not indicate whether the exclusionary clause by itself was ambiguous. In Zurich-American Ins Co v Amerisure Ins Co, 215 Mich App 526; 547 NW2d 52 (1996), this Court determined that the exclusion did not apply when the accident occurred when the truck was being driven to a facility for repair. The opinion does not provide guidance in this case in which the accident occurred following completion of assigned deliveries.
