According to FMCSR §390.201, a Motor Carrier Safety Report update is necessary for the duration of your USDOT number's validity.

The Federal Motor Carrier Safety Administration (FMCSA) mandates that all entities within its jurisdiction update their information biennially. This update is obligatory, even if your company's details remain unchanged or if you have ceased interstate operations or closed your business without notifying the FMCSA.

Failure to complete the Biennial Update could lead to the deactivation of your USDOT number and may result in civil penalties of up to $1,000 per day, with a maximum penalty not exceeding $10,000. Compliance with this requirement is crucial for maintaining regulatory adherence and avoiding potential penalties.
