The Commercial Driver’s License Information System (CDLIS) is a nationwide computer system that enables state driver licensing agencies to confirm that each commercial driver has only one driver’s license and one complete driver record. This can help to mitigate fraud on several levels.

State driver licensing agencies use CDLIS to complete various procedures, including:

  • Transmitting out-of-state convictions and withdrawals.
  • Transferring the driver record when a commercial driver’s license holder moves to another state.
  • Responding to requests for driver status and history.
