Volume 02: A Guide for Addressing Collisions Involving Unlicensed Drivers and Drivers with Suspended or Revoked Licenses

75 Percent of Suspended/Revoked Drivers Continue to Drive

One out of every five fatal crashes involves at least one driver who is not properly licensed (unlicensed or license suspended, revoked, expired, or canceled). In 35 percent of fatal crashes, the driver not properly licensed is judged at fault.

Most drivers respond appropriately to enforcement measures aimed at voluntary compliance with licensing laws and refrain from illegal driving to avoid legal sanctions. Nevertheless, 75 percent of suspended/revoked drivers with licenses continue to drive.

  • Apply special enforcement practices.
  • Restrict mobility through license plate modification or removal.
  • Restrict mobility through vehicle modification.
  • Restrict mobility through direct intervention with offender.
  • Eliminate the need to drive.

NCHRP 500-2
Unlicensed/Suspended/
Revoked Drivers

Two groups of drivers continue to drive without proper licensure: those whose privileges have been taken away by suspension or revocation and those who are driving without ever having received a license. These drivers are especially difficult to reach and to influence. This guide addresses some interventions that have shown promise and are worthy of implementation.
