High school students were surveyed every 6 months from their freshman through senior years concerning licensing, driving, and transportation to and from their various activities. Students in Delaware (learner's permit can be issued at age 15 years, 10 months; driver's license at age 16) were compared with students in Connecticut and New York (permit at age 16; license at age 16) and in New Jersey (license at age 17). During the junior year, most Delaware students, some New York and Connecticut students, and few New Jersey students were licensed. However, even during the junior year, students in the respective states did not differ significantly with respect to time spent at activities such as a paying job, homework, watching television, dating, parties, being with friends, talking on the phone, or participating in sports or school activities. Graduated licensing systems can delay full-privilege teenage licensure and reduce teenage crash rates. These systems also can increase the number of times parents and others must drive. However, the present study's results indicate that licensing delays of as much as 1 year have minimal effects on the nondriving activities of high school students.
