U.S. DOT Biennial Update

The Biennial Update (Form MCS150) is a federal mandate per regulation Title 49 Code of Federal Regulations, Section §390.19T (also known as CFR Title 49 Section 390.201T)

It is a requirement for all owners of a U.S. DOT Number, regardless of fleet size and scale of operations.

A U.S. DOT Number never expires, but the Department of Transportation requires filing an update in three specific cases:

• Before carrier operations begin. 

• Within 30 days of any change in your company status
  (e.g.: number of drivers trucks or trailers, phone number, address)

• Once every two years on a month and year indicated by your U.S. DOT Number per schedule:
      The last digit of the DOT Number corresponds to the month of the deadline
      The digits before the last of the DOT Number corresponds to the year of the deadline

Failure to comply with this mandate may result in deactivation of the DOT Number and/or penalties up to $10,000 per FMCSR 390.201T.

I have just recently opened my business. Do I need to file?

This is one of the most frequently asked questions. The answer is yes, one must file a Biennial Update on a specific month and year combination regardless of when the DOT numbered was opened.

Biennial Update filings must be completed every 24 months. If you miss your initial filing deadline, your next scheduled update will have been more than 24 months from the date you had established your DOT number. As such, if you have recently opened your business you may have to file the initial Biennial Update sooner than two years. For more information please reference regulation FMCSR 390.201T.
