In every motorized country, teenage drivers represent a major hazard. The problem is worse in the United States than elsewhere. We allow teens to get licenses at an earlier age than in most other countries, and little driving experience typically is required before licenses are issued.
Licenses also are inexpensive and easy to get.
Access to vehicles is easier than elsewhere. The result is greatly elevated crash risk among young drivers. Teenagers drive less than all but the oldest people, but their numbers of crashes and crash deaths are disproportionately high. The risk of crash involvement per mile driven among drivers 16-19 years old is 4 times the risk among older drivers. Risk is highest at age 16-17.
