  • Every 24 months, according to the last two digits of the carriers usdot

****To calculate fleet mileage, use the total miles traveled by all vehicles registered under your USDOT in 2023****

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:

Within 30 days of any change in your company status (e.g.: number of drivers, 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 (e.g.: DOT# 10034213 should be filed in March)
The digits before the last of the DOT Number corresponds to the year of the deadline as such: an odd number requires filings in odd-numbered years and an even number requires filings in even-numbered years. (e.g.: DOT# 10034213) should be filed in 2019, 2021, 2023, and so on.
Failure to comply with this mandate may result in deactivation of the DOT Number and/or penalties up to $10,000 per FMCSR 390.201.
