Motus is FMCSA’s new U.S. DOT Registration System, which went fully live on May 19, 2026. It consolidates FMCSA’s legacy registration workflows — including the old FMCSA Portal registration functions and other outdated registration applications — into one centralized online system for applying for, claiming, updating, and managing your USDOT and operating-authority records. Your USDOT and MC numbers and your historical records carry over unchanged.
