All states should enact and enforce a primary enforcement seat belt use law. Child safety seats are designed to protect infants and young children from injury during a collision, swerve, or sudden stop. Studies show there is a direct relationship between increasing BAC and the risk of collision. Before the recent enactment that lifted the 55 mph speed limit, evaluations of the 55 mph speed limit's efficacy indicated a reduction in death and injury of 2,000-4,000 persons in the U.S. annually. The 55 mph speed limit not only reduced speeds, but also reduced the speed variability among cars.
All available evidence indicates that increased speed variability increases the risk of collisions.
To effectively reduce the number of injuries related to motor vehicle crashes, legislative and behavioral changes must be adopted. Without a change in either, prevention initiatives are limited. The Injury Update is a report by the Injury Prevention Service , Oklahoma State Department of Health .
