The FMCSA Biennial Update, also known as the MCS-150 update, is a mandatory requirement for all motor carriers operating under the jurisdiction of the Federal Motor Carrier Safety Administration (FMCSA). This update is crucial for maintaining an active USDOT number and ensuring that the FMCSA has accurate and up-to-date information about the carrier’s operations.

What is the MCS-150?

The MCS-150 (Motor Carrier Identification Report) is the form used to collect essential details about a motor carrier’s business. This includes:

• Company contact information

• Fleet size and classification

• Type of operation (e.g., for-hire, private, exempt)

• Hazmat transportation status

• Vehicle mileage and cargo classifications

How Often is it Required?

The update must be filed every two years, even if there have been no changes to your business information. The due date is based on the last two digits of your USDOT number:

• The second-to-last digit determines the month

• The last digit determines the year (odd/even) you must file in

Failure to file the update on time can result in:

• Deactivation of your USDOT number

• Civil penalties of up to $1,324 per day, with a maximum of $12,968

Who Must File?

All entities with an active USDOT number must file the MCS-150 update, including:

• Interstate and intrastate carriers

• Private carriers

• For-hire carriers

• Brokers and freight forwarders (as applicable)
