As FMCSA continues supporting the transition to Motus, the USDOT Registration System, launched on May 19, and to help reduce disruption during this transition period, FMCSA has temporarily suspended the inactivation of USDOT numbers for entities that have not completed the required biennial update since June 1. Registrants will receive additional time to complete any required biennial updates and should not worry about inactivation resulting from Motus-related access or system issues. We will share additional guidance as recovery and stabilization efforts continue.
