KEY HIGHLIGHTS:

  • The study aimed to determine whether Iowa’s license restriction program identifies older drivers who appear to be at greater crash risk and to assess compliance with license restrictions.

  • A total of 522 drivers 70 and older who were attempting to renew their driver’s licenses at licensing offices in Iowa participated in two telephone surveys: one shortly after renewal to discuss driving before renewal and another six months later to assess any changes.

  • Of the 522 drivers, 232 renewed their licenses without having to take a road test (Group 1), and 290 were required to take a road test; of the drivers taking a road test, 191 renewed without restrictions (Group 2), 93 received restrictions (Group 3), and six had their licenses suspended (Group 4).
