Graduated Driver Licensing in Michigan

Abstract
Unintentional injury from motor vehicle crashes is the leading cause of death among US teenagers.1,2 Crash rates among drivers 16 to 19 years of age, per mile driven, are higher than those for all other age groups,3 and the crash risk among 16- to 17-year-old drivers is almost 3 times as high as among 18- to 19-year-old drivers.4 Yet, driver licensure in the United States has been allowed at young ages and after only minimal classroom education and behind-the-wheel training.
