In this appeal we are asked to *353 reconsider the admissibility of evidence of a plaintiffs non-use of a seat belt as evidence of contributory negligence in light of this state’s adoption of comparative negligence. 1
I
In No. 67515, defendants, Misc.er-Bennett Ford and Monica Tanner, sought to amend their complaint following the deposition of Ronald Hines, M.D., the coroner, during which he opined that, if Nathan Schmitzer, plaintiffs decedent, had used his seat belt, "he would still be alive”. After hearing oral arguments, the circuit court denied defendants’ motion to amend their answer to include the decedent’s failure to use a seat belt as an affirmative defense, but reserved ruling on whether evidence of the decedent’s non-use of a seat belt could be introduced as evidence of decedent’s "comparative nеgligence”. This Court granted defendants’ application for leave to appeal from the order denying their motion to amend and consolidated the case with No. 68924.
In No. 68924, plaintiffs, Kenneth and Viola Seifert, moved to strike the affirmative defense of cоmparative negligence by reason of failure to wear a seat belt. The circuit court issued an opinion and order denying plaintiffs’ motion and ruling that "evidence of availability and use or non-use of seat belts may be admitted for consideration by the jury”. Plaintiffs appeal by leave granted from the order denying their motion to strike.

It is undisputed that prior to the adoption of
*354
comparative negligence in this state, evidence of plaintiffs non-use of a seat belt was not admissible on either the question of plaintiff’s contributory negligence or plaintiff’s failure tо mitigate damages. When first confronted with the issue of the admissibility of evidence of the non-use of a seat belt, this Court reviewed the decisions from other juridictions addressing the "seat-belt defense”.
Romankewiz v Black,
" 'So far as our researсh discloses, no court has yet held an occupant’s failure to buckle his seat belt to be negligence per se. (Citing cases.) If the failure to buckle a seat belt is not negligence per se, it could be contributory negligence only when a plaintiff’s omission to use the belt amounted to a failure to exercise the ordinary care which a reasonably prudent person would have used under the circumstances preceding that particular accident. Since the facts and circumstances preceding any accident will vary, so must conduct constituting due care. Under what circumstances would a plaintiffs failure to buckle his seat belt constitute negligence? If a motorist begins his journey without buckling his belt, ordinarily he will not have time to fasten it when the danger of accident becomes apparent; so the duty to "buckle up” — if any — must have existed prior to the injury. Furthermore, it must be remembered that until one has, or should have, notice of another’s negligence, he is not required to anticipate it. On the contrary, he is entitled to assume that others will use due care for his safety and their own. (Citing cases.)’
*355 "Accordingly, we hold that as a matter of law, [plaintiffs minor] had no duty to wear a seat belt. The plaintiffs failure to fasten his seat belt was not such negligence as to contribute to the cause of the accident. Unbuckled plaintiffs do not cause accidents.” Romankewiz, supra, pp 125-126. (Emphasis in original.)
Relying on the analysis in Miller, supra, this Court further held thаt evidence of a plaintiffs failure to use a seat belt was inadmissible under the theory of avoidable consequences or mitigation of damages. We reasoned that where there was no duty to buckle a seat belt, failure to do so cannot be held to be a breach of the duty to avoid consequences or minimize damages.
One year later, this Court affirmed the holding of
Romankewiz, supra,
in
Selmo v Baratono,
In summary, this Court has consistently opposеd the introduction of evidence of a plaintiffs failure *356 to use a seat belt. This rule was based on our determination that there is no duty to use a seat belt as well as the practical "facts of automobile travel today”, Romankewiz, supra, pp 125-126.

In 1979, the Michigan Supreme Court, acting under its authority to change the common law, replaced the doctrine of contributory negligence as a total bar to recovery with the doctrine of comparative negligence "in the interest of justice for all litigants in this state”.
Placek, supra,
The Supreme Court’s preference for pure comparative negligence was based on the Court’s view that justice is served by a doctrine which "hold[s] a person fully responsible fоr his or her acts and to the full extent to which they cause injury”.
Placek, supra,
*358
Defendants’ interpretation of comparative negligence as a doctrine which focusеs on contribution to injury does not compel the conclusion that evidence of the plaintiffs’ respective failures to use a seat belt should be admissible. Under any interpretation of comparative negligence, no matter how, or to what, negligenсe is compared, the trier of fact must first find that the plaintiff was
negligent.
Negligence will not be found merely upon proof of an act which causes injury; a finding of negligence can be sustained only where the person, in committing the injury-producing act, breached some lеgally cognizable duty.
Butrick v Snyder,
As this Court noted in Romankewiz, supra, p 124, at present, no statute mandates seat-belt use, 5 thus рrecluding defendants from arguing that failure to use a seat belt is negligence per se. Defendants are consequently relegated to arguing that *359 plaintiffs’ failure to wear a seat belt was a breach of plaintiffs’ duty to use ordinary care.
As we discussed in
Romankewiz, supra,
pp 125-126, the problеm inherent in this thesis is identifying when plaintiffs’ failure to "buckle up” became a breach of their duty to use ordinary care. Obviously, the breach had to have occurred prior to the accident. To assert that plaintiffs had a duty to use ordinary care by "buckling up” at some point between entering their cars and immediately prior to the occurrence of the accidents imputes to plaintiffs the anticipation that an accident would occur. But, as a matter of law, plaintiffs had the right to assume that other drivers would obеy traffic laws and use reasonable care. "Contributory negligence cannot be imputed to a plaintiff for failure to anticipate negligent acts of a defendant.”
Koehler v Detroit Edison Co,
The common law fails to provide a basis for concluding that plaintiffs’ failure to wear seat belts was a breach of their duty to use ordinary care. Moreover, imposition of such a duty is an act more appropriately performed by the Legislature. The Legislature is better equipped to consider the various issues raised by a law mandаting seat-belt use, e.g., the majority of the population’s disinclination to wearing seat belts, the contradictory studies regarding the efficacy of seat belts as safety devices, and the collateral problems associated with other types of safety devices. I reiterate the conclusion of the Court of Appeals Judge Fitzgerald, in Romankewiz, supra, p 127, "In summary, it is for the Legislature, which in its wisdom has prescribed seat belts, to prescribe any required use thereof if it chooses.”
We conclude that under our system of compara *360 tive negligence, evidence of a plaintiff’s failure to usе a seat belt is not admissible as evidence of plaintiff’s contributory negligence or of plaintiff’s failure to mitigate damages. The circuit court’s order in No. 67515 is affirmed. The circuit court’s order in No. 68924 is vacated, with instructions to the court to grant plaintiffs’ motion to strike.
Notes
Placek v Sterling Heights,
Our decision in
Placek,
Our research discloses that the majority of comparative negligence jurisdictions have rejected the "sеat-belt defense”. In particular, we note
Taplin v Clark,
6 Kan App 2d 66;
The aforementioned distinction was addressed in
Melesko v Riley,
32 Conn Supp 89;
In my opinion, justice is best served by comparing the parties’ negligent contribution to the accident. For example, suppose that evidence of non-use of a seat belt were admissible on the issue of contributory negligence. Suppose further a defendant who negligently runs through a red light and hits а car driven by an unbelted plaintiff, knocking the plaintiff through the windshield and onto the street. Our hypothetical defendant introduces evidence at trial that had plaintiff been wearing a seat belt, he or she would have suffered 80% less injury. Under a theory which compares nеgligence in terms *358 of contribution to injury, plaintiff’s damage recovery would be reduced by 80%, a result which is to as patently unfair.
Pending before the Michigan Legislature is HB 4203 which requires the use of seat belts. Section 710 E(3) of this proposed bill provides that failure to wear a sеat belt "shall not be considered evidence of negligence nor limit liability of an insurer nor diminish recovery for damages arising out of the ownership, maintenance, or operation of a motor vehicle”. Since we have no way of foreseeing what аction the Legislature will finally take with respect to this proposed legislation, the only weight which we assign to the pending bill is that it supports our view that it would be premature for this Court to impose, at the present time, a duty to wear seat belts on automobile drivers and passengers.
