This paper concerns the evaluation of the warning ticket phase of the North Carolina occupant restraint law, which became effective on October 1, 1985. This evaluation utilises several data files, including: (1) state-wide accident data, (2) state-wide enforcement data, and (3) a probability sample of state-wide belt use by front seat occupants. The evaluation examines changes in belt use and injury distributions after implementation of the law, as compared to appropriate before measures.
