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.
Connecticut sits along the critical I-95 Northeast corridor connecting New York to Boston. The state has strict overweight vehicle enforcement and requires commercial vehicle permits for oversize loads. Port of New Haven handles petroleum and bulk cargo.
If you're a motor carrier operating in or through Connecticut, 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 Connecticut 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.
