Questions truckers ask

What is the MCS-150 biennial update?

It is the form that keeps your USDOT registration current: company details, number of trucks and drivers, and miles driven. Every carrier with a USDOT number files it every two years, even if nothing changed.

What happens if I miss it?

FMCSA can deactivate your USDOT number and charge civil penalties. A deactivated number can get your trucks put out of service at a roadside inspection.

How do I know my month?

The last digit of your USDOT number: 1 = January, 2 = February … 9 = September, 0 = October. The digit before it decides odd or even years.

Is there a fee?

FMCSA does not charge a fee to file the MCS-150 update. Companies that file it for you charge for their service.
