¶ 1. Karl A. Burg, by his legal guardian, Gladys M. Weichert, appeals from the judgment, following a jury trial, dismissing his action against Robert W. Zimmerman and Zimmerman's insurer, Cincinnati Casualty Insurance Co.1 Burg argues that the trial court erred in concluding that Zimmerman's conduct in the operation of a snowmobile was not negligent per se, and that the jury's damages verdict was perverse. Burg is correct and, therefore, we reverse.
I. BACKGROUND
¶ 2. The facts relevant to resolution of the issues on appeal are not in dispute. According to the trial testimony, at approximately 5:30 EM. on November 29, 1995, about one hour after sunset, Burg and a friend were snowmobiling on two snow-covered gravel lanes, *148parallel to Highway 36 in Racine County. The two lanes, under construction and not yet open to automobile traffic, were to become additional lanes of the highway. Zimmerman and a friend, Dean Leighton, were also snowmobiling on the same lanes when they stopped, turned off their motors, and were talking; their snowmobiles, snowmobile suits, and helmets were black. The head lamps and tail lamps of Zimmerman's and Leighton's snowmobiles automatically went out when Zimmerman and Leighton turned off their motors.
¶ 3. Burg and his friend, approaching the location where Zimmerman and Leighton had stopped, did not see them until it was too late. Burg swerved, apparently to avoid Zimmerman's snowmobile, and struck Leighton's snowmobile.2 Burg was thrown approximately forty feet and sustained brain injury, resulting in a coma and the need for prolonged hospitalization and rehabilitation. He has permanent residual physical and cognitive impairments.
¶ 4. Burg sued Zimmerman and his insurer, alleging negligence. In pretrial proceedings, Burg moved for an order declaring that Zimmerman was negligent per se under Wis. Stat. § 350.09(1), which, in relevant part, provides: "Any snowmobile operated during the hours of darkness .. . shall display a lighted head lamp and tail lamp."3 Denying Burg's motion, the trial court ruled, as a matter of law, that Zimmerman had not been "operating" his snowmobile at the time of the accident.
*149¶ 5. During the course of the trial, Burg's attorney suggested that "maybe the Court has made an incorrect ruling up to this point, and maybe the Court can correct its ruling." The trial court, having concluded that because the motor was not on, Zimmerman was not "operating" his snowmobile at the time of the accident, responded that "it's been pretty much a consistent ruling when [snowmobiles are] parked, they're not *150being operated based upon the definition of the word 'operate' in the statutes of this state."4 The trial court, however, commented:
I think the law is stupid, but I'm stuck with what the law is.
You know, I think when two people park their snowmobile[s] out there and are sitting around talking about what route they're going to take, it's hard for me to comprehend how the law can say that's not operating, but it does.
¶ 6. After the jury retired for deliberation, Burg, relying on Wis. Stat. §§ 350.09(1)-(3) and 346.51,5 renewed his motion that the court find Zimmerman *151negligent per se. The trial court replied: "I think the record's clear on that. The motion is denied."6
¶ 7. The jury found neither Zimmerman nor Leighton negligent "with respect to the use" of their snowmobiles. Burg moved for a new trial, again contending that Zimmerman was negligent per se, and also arguing that the jury's determination of damages was "perversely low." The trial court denied his motion, stating that "[tjhere is nothing in this definition [of 'operate' under Wis. Stat. § 350.01(9r)] that supports [Burg's] claim." The court reasoned, "Here the facts show. . . that the defendant was merely sitting on a snowmobile that was not turned on, and that he was not engaged in any physical manipulation or activation of the snowmobile's controls."
II. DISCUSSION
A. Negligence Per Se
¶ 8. We agree that if, as the trial court concluded, turning off one's snowmobile motor and sitting on the snowmobile on a snowmobile lane in the dark did not *152constitute "operating," the law would be "stupid." We conclude, however, that the statutes, literally read and reasonably applied, establish that such conduct does indeed constitute "operating" a snowmobile.
¶ 9. The interpretation of a statute presents a question of law subject to this court's de novo review. Gloudeman v. City of St. Francis, 143 Wis. 2d 780, 784, 422 N.W.2d 864 (Ct. App. 1988). "In construing a statute, the primary source is the language of the statute itself." County of Milwaukee v. Proegler, 95 Wis. 2d 614, 625, 291 N.W.2d 608 (Ct. App. 1980). Interpreting the language of the statute, we endeavor to give the words their commonsense meanings and to avoid any interpretation that would produce an absurd result. See Ford Motor Co. v. Lyons, 137 Wis. 2d 397, 449, 405 N.W.2d 354 (Ct. App. 1987). We conclude that "operate," under Wis. Stat. § 350.01(9r), is clear and unambiguous, see Proegler, 95 Wis. 2d at 624-29 (concluding that the meaning of "operate," under Wis. Stat. § 346.63(3), is clear), and that it does encompass Zimmerman's conduct in this case.
¶ 10. "Operate," under Wis. Stat. § 350.01(9r), includes "the exercise of physical control over the speed or direction of a snowmobile." "Operate," therefore, necessarily encompasses a person's actions in stopping a snowmobile and turning off its motor because, literally, such actions do "exercise physical control over the speed and direction" of the snowmobile. The fact that such actions stop the snowmobile certainly renders those actions no less controlling of speed and direction than other actions that accelerate the snowmobile or change its course.
*153¶ 11. Further, under the statute, turning off the motor certainly, and quite literally, involves "the physical manipulation ... of the controls of a snowmobile necessary to put it in motion." The fact that the manipulation stopped the snowmobile's motion certainly renders that action no less a manipulation of the controls necessary to put the snowmobile in motion. Indeed, in Proegler, this court, in determining the meaning of "operate" under Wis. Stat. § 346.63(3)(b),7 held that "restraining the movement of a running vehicle constitutes physical manipulation of a vehicle's controls which falls within the scope of our statute." Proegler, 95 Wis. 2d at 627-28. Obviously, turning off a snowmobile's motor is a "physical manipulation" of the controls, causing a "restraining [of] the movement" of the snowmobile.
¶ 12. Moreover, while Proegler involved a drunk driver sleeping in his car with the motor running, id. at 624, this court's comments now gain special significance in the context of the instant case:
"[0]ne could have 'actual physical control' while merely parking or standing still so long as one was keeping the car in restraint or in position to regulate its movements. Preventing a car from moving is as much control and dominion as actually putting the car in motion on the highway. Could one exercise any more regulation over a thing, while bodily present, than prevention of movement or curbing movement!?] As long as one were physically or bodily able to assert dominion, in the sense of movement, then he [or she] has as much control over an object as he [or she] would if he [or she] were actually driving the vehicle."
*154Id. at 628 (quoting State v. Ruona, 321 P.2d 615, 618 (Mont. 1958)). Indeed, a drunk driver, sleeping in a parked car with the motor running, has less physical control over that vehicle than a snowmobile operator, sitting awake at the controls of a parked snowmobile with the motor off.8 See also State v. Modory, 204 Wis. 2d 538, 544, 555 N.W.2d 399 (Ct. App. 1996) C'Proegler does not say that movement is necessary; rather, it merely says that if the defendant exercises dominion in the sense of movement, then the fact of operation has been established.").
¶ 13. As Burg correctly argues, the legislature, quite obviously, enacted the detailed requirements of Wis. Stat. § 350.09 in part because it "wants snowmo-bilers at night to illuminate their head and tail lamps so other people in the vicinity can see them." See Parr v. Douglas, 253 Wis. 311, 318-19, 34 N.W.2d 229 (1948) (explaining that statutes governing trailer lights establish safety standards, the violation of which "shall be prima facie evidence of unsafe practices in the use of the public highway by such vehicles"). To conclude, nevertheless, that the, mandate of § 350.09(1) does not apply to the circumstances of this case would indeed be *155"stupid." Such a conclusion would require an absurd statutory interpretation precluding the literal reading and commonsense application of the statute to one of the most serious dangers these safety standards are intended to prevent.9 See Lyons, 137 Wis. 2d at 449 (explaining that statutes are to be construed 'to avoid absurd results).
B. Damages
¶ 14. Burg also argues that "[t]he jury's award of damages was so perverse that it warrants a new trial in the interests of justice." He explains that "[his] medical condition was never in issue," and that the defense "called no medical witnesses" to counter the undisputed evidence of his permanent injuries. Further, he points out that the jury awarded damages that were considerably less than what even the defense suggested.
¶ 15. Zimmerman does not dispute Burg's factual assertions. See Charolais Breeding Ranches, Ltd. v. FPC Sec. Corp., 90 Wis. 2d 97, 109, 279 N.W.2d 493 (Ct. App. 1979) (unrefuted arguments deemed admitted). He, simply argues that "[e]ven if this court were to find the damages awarded by the jury in this case inad*156equate, a new trial in the interests of justice is not warranted." Zimmerman, however, premises his argument on the principle that "where the jury verdict finding the plaintiff solely negligent in causing his own injuries is supported by credible evidence upon the record, inadequate damages is not a ground for a new trial." True enough; but where, as here, the jury's verdict cannot stand because the plaintiff was denied the correct ruling on Zimmerman's negligence per se, a new trial is required on both liability and damages. See Martin v. Allstate Ins. Co., 45 Wis. 2d 657, 663, 173 N.W.2d 646 (1970) (when damages award has been challenged as excessive, and error in law necessitates new trial in interests of justice, "the issue of damages should be retried with the issue of liability"); Mainz v. Lund, 18 Wis. 2d 633, 645, 119 N.W.2d 334 (1963) (although inadequate damages award "is not in itself grounds for ordering a new trial where a jury has answered other questions in the verdict so as to find no liability on the part of the party charged with negligence," the inadequate damages award may be significant in determining whether interests of justice require new trial where "the finding of no liability is against the great weight of the evidence").
By the Court. — Judgment reversed.
The appeal also brings before this court the trial court order denying Burg's postverdict motion for a new trial. See Wis. Stat. Rule 809.10(4) (1999-2000). All references to the Wisconsin Statutes are to the 1999-2000 version unless otherwise noted.
None of the issues in this appeal, however, turns on the fact that Burg struck Leighton's snowmobile, not Zimmerman's.
It was undisputed that Zimmerman's and Leighton's snowmobiles had neither their head lamps nor tail lamps illuminated at the time of the accident. WISCONSIN Stat. § 350.09(2) provides:
*149After February 12,1970, the head lamp on a snowmobile may be of the single beam or multiple beam type, but in either case shall comply with the following requirements and limitations:
(a) The head lamp shall be an electric head lamp and the current shall be supplied by a wet battery and electric generator, by a current-generating coil incorporated into the magneto or by a generator driven directly by the motor by means of gears, friction wheel, chain or belt.
(b) The head lamp shall display a white light of sufficient illuminating power to reveal any person, vehicle or substantial object at a distance of 200 feet ahead.
(c) If the snowmobile is equipped with a multiple beam head lamp, the upper beam shall meet the minimum requirements set forth in par. (b) and the lower most beam shall be so aimed and of sufficient intensity to reveal persons and vehicles at a distance of at least 100 feet ahead.
(d) If the snowmobile is equipped with a single beam lamp, such lamp shall be so aimed that when the vehicle is loaded none of the high intensity portion of the light, at a distance of 25 feet ahead, projects higher than the level of the center of the lamp from which it comes.
Section 350.09(3) provides, "After February 12, 1970, the tail lamp on a snowmobile must display a red light plainly visible during darkness.from a distance of 500 feet to the rear."
" 'Operate' means the exercise of physical control over the speed or direction of a snowmobile or the physical manipulation or activation of any of the controls of a snowmobile necessary to put it in motion." Wis. Stat. § 350.01(9r).
WISCONSIN Stat. § 346.51, in relevant part, provides:
(1) No person shall park, stop or leave standing any vehicle, whether attended or unattended, upon the roadway* of any highway . . . when it is practical to park, stop or leave such vehicle standing off the roadway, but even the parking, stopping or standing of a vehicle off the roadway of such highway is unlawful unless the following requirements are met:
(b) Such standing vehicle must be capable of being seen by operators of other vehicles from a distance of 500 feet in each direction along such highway.
(Emphasis and asterisk added.) Under Wis. Stat. § 346.02(10), § 346.51 is applicable to operators of snowmobiles upon roadways.
Wisconsin Stat. § 340.01(54) states, in relevant part, " 'Roadway' means that portion of a highway between the *151regularly established curb lines or that portion which is improved, designed or ordinarily used for vehicular travel, excluding the berm or shoulder."
Earlier in the trial, outside the presence of the jury, the court had explained why it believed that Wis. Stat. § 346.51 did not apply to the case:
This isn't designed to protect snowmobiles from driving 55 feet off the highway. It's designed to protect vehicles that are traveling on the roadway.
It requires that. .. the vehicle when stopped off the roadway is visible 500 feet back for the protection of people who are using ' the roadway, not for the protection of the people who are using the land adjacent to the roadway some 55 feet off the roadway.
Wisconsin Stat. § 346.63(3)(b) provides, " 'Operate' means the physical manipulation or activation of any of the controls of a motor vehicle necessary to put it in motion."
And, indeed, affirming the trial court's interpretation would render a truly ironic result: the operator of a snowmobile that is stopped with its motor off would not be negligent per se, while the operator of a snowmobile that is stopped with its motor on would be negligent per se, although he or she would be better able to quickly respond to a dangerous situation. As Burg fairly argues:
[E]veryone agrees that Zimmerman would have been negligent per se for sitting in the dark with his engine running and his lights off. To then argue that he is not negligent per se by turning both his engine and lights off only rewards Zimmerman for his unreasonable action. This is nonsense.
The dangers of snowmobiling are extremely serious. According to the Wisconsin Department of Natural Resources, thirty-eight fatal snowmobile accidents were reported in Wisconsin for fiscal year 1999-2000, and collision with an object was the leading cause of death. Wis. Dep't of Natural Res., 1999-2000 Snowmobile Program Report Summary, at http://www.dnr.state.wi.us/org/es/enforcement/safety/snow-mobile_report.html. Not surprisingly, therefore, the legislature has made the "operator of a snowmobile upon a roadway" subject to numerous rules of the road governing operators of other motor vehicles. See Wis. Stat. § 346.02(10).
