OPINION
¶ 1 This appeal requires us to decide whether a vehicle owner may bear tort liability for a death arising from the absence of a safety belt. Specifically, may a jury find that the owner must maintain the safety belt as part of his duty to keep his vehicle in safe operating condition? Is state tort law liability permitted despite the existence of federal safety regulation of vehicle manufacturers?
¶2 We answer both of these questions affirmatively. Accordingly, we reverse the superior court’s summary judgment for Defendant vehicle owners.
¶3 Sadly, this case involves the death of the fifteen-year-old son of Defendant Warren Francisco III and of Plaintiff Jana L. Hutto. Their son was driving a 1971 Chevrolet pickup truck owned by himself and his father. The son was involved in a single-vehicle accident in which he was ejected from the vehicle. The truck lacked any safety belts.
¶4 The 1971 model truck was manufactured with safety belts. 1 At the time, federal law did not yet require safety belts, but the manufacturer had installed them.
¶ 5 Defendant and his son purchased the track in 1999. 2 The track then lacked the belts, but retained the cutouts in the seat for the belts. Defendant refurbished the truck after he purchased it, but did not replace the missing belts.-
¶ 6 Plaintiff alleged that Defendants were negligent. The superior court granted summary judgment in favor of Defendants Warren Francisco III and his wife. The court apparently decided that, as a matter of law, the failure to reinstall safely belts in their vehicle was not unreasonable and could not constitute negligence. Plaintiff timely appealed. Our jurisdiction rests on Arizona *90 Revised Statutes (“A.R.S.”) section 12-2101(B) (2003). In a timely cross-appeal, Defendants contend that the court erred in ruling that this action is not preempted by federal law. 3
¶7 We first address Defendants’ argument that this action is preempted by federal law. We review federal preemption issues de novo.
Hill v. Peterson,
¶ 8 Express preemption does not bar this action. Defendants rely on the National Traffic and Motor Vehicle Safety Act of 1966, Pub.L. 89-563, 80 Stat. 718, and the Federal Motor Vehicle Safety Standards, 49 U.S.C. § 30101, et seq. (2004) (formerly 15 U.S.C. § 1381 et seq.). However, Defendants cite no preemption provision. On the contrary, Congress disavowed such a purpose: “Compliance with a motor vehicle safety standard prescribed under this chapter does not exempt a person from liability at common law.” 49 U.S.C. § 30103(e) (2004) (formerly 15 U.S.C. § 1397(k)).
See Geier v. Am. Honda Motor Co.,
¶ 9 Field or implied preemption also does not preclude this action. Defendants rely on
Hernandez-Gomez v. Volkswagen,
¶ 10 Nor does preemption arise from conflict between state law and federal statutes. The Federal Motor Vehicle Safety Standards required passenger cars manufactured after January 1, 1968 to include seat-belts, and pickup trucks manufactured after January 1, 1972
4
to include the same. Defendants assert that this creates a conflict. Actual conflict between federal and state law occurs, for purposes of preemption, when it is impossible to comply with both federal and state law, or “where state law ‘stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress.’ ”
Hernandez-Gomez,
¶ 11 We now turn to whether Plaintiff has a viable tort claim under state law. Plaintiff’s claim should not have been rejected by summary judgment. Summary judgment is appropriate only where there are no genuine issues of material fact and the moving party is entitled to judgment as a matter of law.
Orme Sch. v. Reeves,
¶ 12 Plaintiff first argues that Defendants were negligent per se because they failed to reinstall the safety belts, thus allowing the truck to be driven in an unsafe condition in violation of A.R.S. § 28-921(A)(1)(a) (2004). “Negligence per se applies when there has been a violation of a specific requirement of a law.”
Griffith v. Valley of the Sun Recovery and Adjustment Bureau, Inc.,
¶ 13 However, the statute involved, A.R.S. § 28-921(A)(l)(a), does not create a sufficiently specific standard by which conduct is to be measured. It provides only a general principle that vehicles must be safely maintained, and does not specifically require safety belts. The statute provides:
A. A person shall not:
1. Drive or move and the owner shall not knowingly cause or permit to be driven or moved on a highway a vehicle or combination of vehicles that:
(a) Is in an unsafe condition that endangers a person.
A.R.S. § 28-921(A)(1)(a).
¶ 14 Such a general standard does not support negligence per se. “The statute or regulation must ‘proscribe certain or specific acts’ to support a finding of ... negligence
per se."
Jefferson L. Lankford & Douglas A. Blaze,
The Law of Negligence in Arizona §
3.05[2] (3d ed.2004) (quoting
Griffith,
¶ 15 Although Defendants were not negligent per se, a jury might find negligence under the common law standard. Negligence requires proof of a duty owed to the plaintiff, a breach of that duty, an injury proximately caused by that breach, and damage.
Ontiveros v. Borak,
V16 The superior court correctly found that Defendants had a duty not to expose users of the vehicle to an unreasonable risk. The owner of a vehicle has a duty to maintain his vehicle in a reasonably safe condition.
See
A.R.S. § 28-921(A)(1)(a).
See also Siverson v. Martori, 119
Ariz. 440, 443,
¶ 17 The court, however, incorrectly granted Defendants’ motion for summary judgment because it found the risk of harm was not unreasonable. This question should have been left for the jury to resolve.
*92
¶ 18 While “[n]ot every foreseeable risk is an unreasonable risk,” deciding whether a risk was unreasonable “requires an evaluative judgment ordinarily left to the jury.”
Rogers v. Retrum,
¶ 19 We cannot say as a matter of law that it is unreasonable to expect an owner to maintain the original safety equipment in the vehicle installed by the manufacturer, or that the risk posed by the absence of such equipment is one that motorists or passengers should reasonably bear. “As a general rule, a motorist is simply better off wearing a seat belt.”
Law v. Superior Court,
¶20 The importance of such devices in preventing death and avoiding injury is beyond doubt. Lack of a safety restraint markedly increases the risks of ejection from the vehicle and of death. In 2003, according to the National Highway Traffic Safety Administration, 70 percent of pickup truck drivers killed in traffic crashes were not using restraints. U.S. Department of Transportation, National Center for Statistics & Analysis, Traffic Safety Pacts 2003 — Occupant Protection, DOT HS 809 765. The government further reported that use of safety belts reduces risk of fatal injury by 60 percent for light truck occupants.
Id.
Moreover, in 2003, 74 percent of passengers ejected from the vehicle were killed.
Id. See also Law,
¶21 Other jurisdictions have considered similar situations. In
Tiemeyer v. McIntosh,
The defendant cab company was under no statutory duty to have seat belts in its cab at the time this accident occurred. We believe the issue of negligence for failing to provided [sic] such a safety device was properly determined as a question of fact and not as a matter of law.
Id.
Similarly, in
Mortensen v. Southern Pacific Company,
¶ 22 Defendants emphasize that they did not remove the safety belts. Instead, they merely failed to replace them when the truck was refurbished by Defendants after its purchase. This is a fact that distinguishes this case from others in which liability was allowed when the owners removed the safety belts, such as Twohig v. Briner.
¶23 We are unpersuaded, however, that this distinction relieves Defendants of liability as a matter of law.
See Tiemeyer, supra.
Defendants concede that they owed a duty to provide a reasonably safe vehicle. The existence of a duty requires the person subject to the duty to exercise reasonable care under the circumstances.
Markowitz v. Ariz. Parks Bd.,
¶ 24 Son, as a co-owner of the vehicle, may have been comparatively negligent for failing to install the safety belts. “[U]nder the comparative fault statute, each person is under an obligation to act reasonably to minimize foreseeable injuries and damages.”
Law,
¶ 25 Accordingly, we affirm the court’s denial of Defendants’ motion for summary judgment based on federal preemption. However, we reverse the summary judgment in favor of Defendants, and remand for further proceedings.
Notes
. Defendants admit for purposes of summary judgment the allegation that the truck was manufactured with safety belts, but reserve the right to dispute the fact at trial.
. The previous owners are not parties to this action.
. Defendants first moved for summary judgment, arguing that federal law preempted Plaintiff’s claim. The superior court denied this motion. Defendants filed a second motion for summary judgment, arguing that they had no duty to reinstall the safety belts. Plaintiff filed a cross-motion for summary judgment, contending that Defendants were negligent as a matter of law. The court granted Defendants' second motion and denied Plaintiff's motion.
. The record does not reveal the exact date of manufacture of the truck, but does show that it was a 1971 model. If manufactured prior to the effective date of the federal mandate, the absence of a conflict is apparent.
. Maintain is defined as ”[t]o continue [or to] preserve or keep in a given existing condition.” Webster's II New College Dictionaiy 660 (2001).
