Abstract

Does the tendency of teenage drivers to be involved in automobile accidents increase dramatically with the number of passengers in the car? Believing this to be so, legislators in several states require that junior license holders be prohibited from driving with more than one passenger. Is the GES 2000--2014 data consistent with earlier 2001 Insurance Institute for Highway Safety results? Are the restrictions on junior license holders still justified?
