New Jersey started enforcing a graduated driver license (GDL) system on January 1, 2001. The system requires a three-step process for full licensing: learner's permit at 16 years of age at the earliest; provisional license at 17; and, a basic license at 18. This report is the first phase of an evaluation of the New Jersey GDL system. The number and types of traffic crashes, traffic violations, and license suspensions in New Jersey by age for the years immediately before 2001 were analyzed. The second phase will look at the same type of data after 2001 and will compare the results to the pre 2001 analysis to determine what the impact of GDL has been. The analysis of the pre-2001 data shows that 17 year olds have substantially more crashes and violations per 10,000 people compared to other drivers. A higher percentage of their crashes are single vehicle crashes. In addition, a much higher percent of their crashes are due to unsafe speed, and a higher percent of their crashes are due to inattention, and a failure to obey traffic control devices or yield right of way, compared to middle aged drivers. A higher percent of their violations are due to speeding than any other group, and a higher percent are due to careless driving than for middle aged drivers. (Author/publisher)
