It is now beyond question that the use of automotive safety belts goes a long way to reducing the number of injuries and deaths occasioned by auto accidents. When those belts are combined with the air bags in newer models of motor vehicles, the survivability of motor accidents increases greatly.
It is somewhat of an historical anomaly that while auto manufacturers were required by law to install safety belts in new vehicles starting about the middle of the last century, the same laws did not mandate the use of those belts by vehicle occupants. A strong case can and has been made that regardless of statutory mandate, a reasonable person of ordinary prudence would make use of available automotive belts. Since most states now require safety belt use, e.g., Wis. Stat. § 347.48(2m), that argument is no longer necessary. Thus the legislatures have established a standard of care.
However, an example of the lobbying power of the plaintiffs’ personal injury bar may be seen in the fact that many state belt use statutes contain provisions limiting reduction of an auto accident victim’s damages if he or she did not use an available safety belt. For example, Wis. Stat. § 347.48(2m)(g) provides that damages may not be reduced by more than fifteen percent.
