Why the MCS-150 Biennial Update Matters
Every motor carrier operating under an active USDOT number is legally required by the Federal Motor Carrier Safety Administration (FMCSA) to update its census information every 24 months using Form MCS-150, even if no company details or fleet counts have changed.
How to Determine Your Filing Month and Year
- Next-to-Last Digit of USDOT Number: Odd digits file in odd-numbered calendar years; even digits file in even-numbered calendar years.
- Last Digit of USDOT Number: Dictates the exact filing month from January (1) through October (0).
Consequences of Missing Your Deadline
Failure to complete a timely biennial update can result in immediate deactivation of your USDOT authority and civil penalties up to $1,000 per day.
