An MCS-150 biennial update is a mandatory federal requirement under 49 CFR Part 390 for all USDOT-registered motor carriers. FastMCS150 prepares and submits the biennial update online for $175 standard or $400 lifetime updates.
California has the largest number of registered motor carriers in the nation. The Ports of Los Angeles and Long Beach together handle approximately 40% of all containerized imports entering the U.S. Carriers must also comply with CARB (California Air Resources Board) emissions regulations, which impose additional requirements beyond federal FMCSA standards.
If you're a motor carrier operating in or through California, federal law (49 CFR Part 390) requires you to file your MCS-150 biennial update with the FMCSA every two years to keep your USDOT record current.
The MCS-150 biennial update keeps your USDOT registration current with the FMCSA, including your company address, vehicle count, and driver information for California operations. A missed biennial update can lead to civil penalties and deactivation of the USDOT number (49 CFR 390.19T(b)(4)). Note: FMCSA has temporarily suspended enforcement of biennial updates and USDOT inactivation for updates due on or after June 1, 2026, until further notice.
