Every US state requires drivers to pass a knowledge and skills examination before obtaining their driver's license. Surprisingly little is known about the progression of people through the examination process. To date, no research has been conducted on the proportion of individuals who pass from one stage of the driver examination process to the next compared to those who fail and are required to be reexamined. The purpose of this study was to follow the progression of a cohort of new drivers in Washington State as they advanced through the driver examination process. We reviewed driving records for 2,604 teens who started a driver education course in 2024. Of those who attempted the knowledge test at least once, 96 percent passed their knowledge test and 85 percent passed their skills exam. There were significant differences in pass and fail rates by sex, race, and household income. The overwhelming majority of new drivers passed both the knowledge and skills exams after two attempts. The fact that teenagers have a high risk of crashing in the first year of licensure suggests that the full safety potential of the knowledge and skills exams are not being realized.
