The Biennial Update (Form MCS150) is a federal mandate per regulation FMCSR 390.201 (also known as CFR Title 49 Section 390.201)
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 two specific cases:
Failure to comply with this mandate may result in deactivation of the U.S. DOT Number and/or penalties up to $10,000 per FMCSR 390.201.
Name: Biennial Update
Regulation Code: FMCSR 390.201
Due Date: determined by your U.S. DOT #
Frequency: filed once every 2 years
Who is it for?: every U.S. DOT Number holder
Penalty: deactivated U.S. DOT and/or up to $10,000
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 U.S. 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 U.S. 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 390.201.
