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.
South Carolina's Port of Charleston is one of the fastest-growing container ports on the East Coast. The SC Ports Authority also operates the Inland Port in Greer, which connects to the port via Norfolk Southern rail - extending the port's reach 212 miles inland. BMW, Boeing, and Volvo manufacturing drive significant automotive freight.
If you're a motor carrier operating in or through South Carolina, 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 South Carolina 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.
