The effect of legislation on injuries sustained by rear seat car passengers.

A study of 206 injured rear seat passengers was undertaken over two 4-month periods before and after the introduction of legislation enforcing use of rear seat-belts on 1 July 1991. The proportion of both adults and children using rear seat-belts increased after the law. Those wearing belts were less likely to suffer serious injury. The majority of passengers comply with the law but many rear seat passengers remain unrestrained because cars are not fitted with belts.
