Before: HOEKSTRA, P.J. and JANSEN and KIRSTEN FRANK KELLY, JJ.
PER CURIAM.
In this automobile negligence action, defendant Mecosta County Road Commission appeals as of right the trial court's ruling that a Gradall hydraulic excavator is a motor vehicle for the purposes of the motor vehicle exception to governmental immunity found in MCL 691.1405. Plaintiffs Daniel J. and Beverly Wesche cross-appeal the trial court's dismissal of Beverly Wesche's loss-of-consortium claim. We affirm.

I. Basic Facts
It is undisputed that one afternoon in March 2000, Daniel Wesche stopped for a red traffic light at the intersection of State Street and Woodward Avenue in the city of Big Rapids. While he was stopped, the rear of his vehicle was struck by a Gradall XL 4100 driven by defendant's employee. According to plaintiffs' complaint, the impact caused serious injury to Daniel Wesche's cervical spine. Plaintiffs filed a complaint against defendant alleging that Daniel Wesche suffered physical, mental, and emotional injury and economic damages. Beverly Wesche alleged that she suffered loss of consortium caused by her husband's injuries.

II. The Gradall is a Motor Vehicle Under MCL 691.1405
Defendant argues that the trial court erred in ruling that the Gradall was a motor vehicle for the purposes of the motor vehicle exception to governmental immunity found in MCL 691.1405. We disagree. This Court reviews de novo decisions on summary disposition motions. Stanton v. Battle Creek, 466 Mich. 611, 614, 647 N.W.2d 508 (2002). This issue does not present an issue of statutory interpretation, but one of statutory application.
The governmental tort liability act, MCL 691.1401 et. seq., provides that a governmental agency is immune from tort liability while engaging in a governmental function unless a specific exception applies. Governmental immunity is broad, and the five exceptions are narrowly drawn. Stanton, supra at 615, 647 N.W.2d 508. The motor vehicle exception to governmental immunity, MCL 691.1405, provides:

*138 Governmental agencies shall be liable for bodily injury and property damage resulting from the negligent operation by any officer, agent, or employee of the governmental agency, of a motor vehicle of which the governmental agency is owner, as defined in Act No. 300 of the Public Acts of 1949, as amended, being sections 257.1 to 257.923 of the Compiled Laws of 1948.
In Stanton, supra at 616, 647 N.W.2d 508, the Court determined that "[t]he motor vehicle exception does not define `motor vehicle.'" The Court rejected the contention, also suggested by defendant in this case, that the reference in MCL 691.1405 to the Michigan Vehicle Code, MCL 257.1 et. seq., provided the definition of "motor vehicle" for the purposes of MCL 691.1405. Stanton, supra at 616, 647 N.W.2d 508. After determining that the term "motor vehicle" was not otherwise defined in the governmental tort liability act, the Court adopted a dictionary definition of the term "motor vehicle," that being: "`an automobile, truck, bus, or similar motor-driven conveyance.'" Id. at 618, 647 N.W.2d 508 (citation omitted). Applying this definition, the Court concluded that the forklift in that case was not a motor vehicle for the purposes of MCL 691.1405. The Court held: "A forklift  which is a piece of industrial construction equipment  is not similar to an automobile, truck, or bus." Stanton, supra at 618, 647 N.W.2d 508 (emphasis in original).
Later, in Chandler v. Muskegon Co., 467 Mich. 315, 322, 652 N.W.2d 224 (2002), the Supreme Court held that the motor vehicle exception to governmental immunity did not apply when the plaintiff was injured by a bus parked in a maintenance facility. The Court held that the motor vehicle exception did not apply because the vehicle was not being "operated" when the injury occurred. Id.
In Regan v. Washtenaw Co. Bd. of Co. Rd. Comm'rs. (On Remand), 257 Mich.App. 39, 47-51, 667 N.W.2d 57 (2003), this Court held that a broom tractor and a tractor mower were motor vehicles for the purposes of MCL 691.1405. This Court reasoned that "both vehicles are motor driven conveyances," and rejected the suggestion that a motor vehicle must have transportation as a primary function in order to qualify as a motor vehicle under MCL 691.1405. Regan, supra at 47-48, 667 N.W.2d 57. This Court explained that a broom tractor and a tractor mower "are comparable to an automobile, bus, or truck," and, like those vehicles, are "invariably connected to the roadways...." Id. at 48, 667 N.W.2d 57.
Applying these decisions to the case at hand, we conclude that the Gradall is a motor vehicle for the purposes of MCL 691.1405. The Gradall, a wheeled, motorized vehicle operated by a driver, generally resembles a truck and moves like a truck. The significant difference between it and a truck is that mounted on the back of the vehicle is a unit that operates a hydraulic excavation tool. Although defendant argues that the Gradall is not used primarily for transportation, none of the cases cited above requires the motor vehicle to be used primarily for transportation for MCL 691.1405 to apply. Moreover, when the Gradall is not being used for excavation, it can be driven along the roadways just like a truck and transports both its attached excavation unit and the driver. At the time of the accident in this case, the driver was returning the Gradall to defendant's garage from the project site. The Gradall was being driven on a public roadway when it struck the rear of Daniel Wesche's vehicle. Under these circumstances, we conclude that the trial court did not err in ruling that the Gradall is a motor vehicle for the purposes of MCL 691.1405.


*139 III. MCL 691.1405 Does Not Provide an Exception to Governmental Immunity for Loss-of-Consortium Claims
On cross-appeal, plaintiffs argue that the trial court erred in ruling that Beverly Wesche's loss-of-consortium claim is barred by governmental immunity. We disagree and hold that loss-of-consortium claims are not included in the motor vehicle exception to governmental immunity found in MCL 691.1405. We review de novo issues of statutory interpretation. Stanton, supra at 614, 647 N.W.2d 508. The primary rule of statutory interpretation is that we are to effect the intent of the Legislature. To achieve this task, we must first examine the statute's language. If the language is clear and unambiguous, we assume the Legislature intended its plain meaning, and the statute is enforced as written. Id. at 615, 647 N.W.2d 508.
Pursuant to MCL 691.1405, "Governmental agencies shall be liable for bodily injury and property damage resulting from the negligent operation by any officer, agent, or employee of the governmental agency, of a motor vehicle. . . ." In this case, plaintiffs alleged:
As a result of the injuries and damages to Daniel John Wesche, his spouse, Beverly Wesche, has further been damaged by being denied the normal marital companionship and services from the date of Daniel's physical injuries up to the present, with their being a reasonable likelihood/probability that some element of same will be permanent.
Loss of consortium is a separate cause of action; this has been the law in Michigan since at least 1960. Wessels v. Garden Way, Inc., 263 Mich.App. 642, 648, 689 N.W.2d 526 (2004). However, "`[a] claim of loss of consortium is derivative and recovery is contingent upon the injured spouse's recovery of damages for the injury.'" Id., quoting Berryman v. K Mart Corp., 193 Mich.App. 88, 94, 483 N.W.2d 642 (1992). Thus, loss-of-consortium claims do not encompass bodily injury or property damage, but other damages deriving from the spouse's injury. None of the damages alleged by Beverly Wesche is bodily injury or property damage. Therefore, because the governmental immunity exception provided in MCL 691.1405 does not apply to Beverly Wesche's loss-of-consortium claim, the trial court did not err in dismissing this claim.
Affirmed.
