Are any interstate carriers exempt from filing a MCS-150?

A motor carrier that registers its vehicles in a state that participates in the Performance and Registration Information Systems Management (PRISM) program is exempt from this requirement, provided the motor carrier files all the required information with the appropriate state office.

Many PRISM states defer enforcement to the FMCSA and allow the USDOT number deactivation process to occur. If the state does require an MCS-150 update, the carrier needs to file the update directly with the FMCSA.
