California's Graduated Licensing Program is Reducing Crashes, Especially Ones with Lots of Teens in a Vehicle

This article reports on a study by the Insurance Institute on the results of California’s graduated licensing program, which took effect in 1998. The study found a 23 percent reduction in the per-capita crash involvement rate of 16-year-old drivers. Nighttime crash rates were reduced by 27 percent, while crash rates with teen passengers dropped 38 percent. Beginning in 1998 the learner’s permit period was increased, and required parents to certify that their teenage learners received at least 50 hours of practice. In addition, 16-year-olds who are licensed are not allowed to drive unsupervised at night or at any time with teenage passengers. The Institute study was prompted by another study in 2003 that found no decrease in the number of crashes. However, the Institute points to other studies that have reported positive effects of graduated licensing programs in other states.
