Performance and Registration Information Systems Management — PRISM

PRISM is a cooperative federal/state safety program. It's designed to identify motor carriers with poor safety records and tie a motor carrier's safety fitness to the ability to register their trucks.

PRISM links the Federal Motor Carrier Safety Administration's safety information with the state's motor vehicle registration process to achieve 2 purposes:

  • Determine the motor carrier's safety fitness before issuing them a license plate.
  • Motivate the unsafe carrier to improve its safety performance through an improvement process and registration sanctions.

For more information about PRISM, visit Federal Motor Carrier Safety Administration.
