Highway crash costs in the United States by driver age, blood alcohol level, victim age, and restraint use.
This paper estimates 1993 U.S. highway crash incidence and costs by driver age, alcohol use, victim age, occupant status, and restraint use. Notable findings are: (1) crash costs of novice drivers are high enough to yield preliminary benefit-cost ratios around 4-8 for a provisional licensing system that restricts driving after midnight and 11 for zero alcohol tolerance for young drivers with violators receiving a 6-month suspension; (2) the costs to people other than the intoxicated driver per mile driven at BACs of 0.08-0.099% exceed the value of driver mobility; (3) the safety costs of drunk driving appear to exceed $5.80 per mile, compared with $2.50 per mile driven at BACs of 0.08-0.099%, and $0.11 per mile driven sober; (4) highway crashes cause an estimated 3.2% of U.S. medical spending, including more than 14% of medical spending for ages 15-24; (5) ignoring crash-involved occupants whose restraint use is unknown, the 13% of occupants who police reported were traveling unrestrained accounted for an estimated 42% of the crash costs; and (6) if these unrestrained occupants buckled up, the medical costs of crashes would decline by an estimated 18% (almost $4 billion annually) and the comprehensive costs by 24%.
