Staying compliant with FMCSA regulations is essential for every motor carrier, trucking company, or interstate commercial vehicle operator. One of the most critical compliance tasks is the MCS 150 Form Update, a required biennial filing that keeps your USDOT number active and your company in good standing with federal safety authorities. In this guide, we’ll break down what the MCS 150 update is, why it matters, and how carriers can complete this important requirement efficiently using professional services like USDOTDATA.
What Is the MCS 150 Form Update?
The MCS 150 is a Motor Carrier Identification Report required by the Federal Motor Carrier Safety Administration (FMCSA). This form collects essential company data—including your operational address, business name, fleet size, and contact information—that helps federal authorities monitor safety and regulatory compliance. Every carrier with an active USDOT number must file this update every two years or whenever there’s a significant change to their business.
This requirement applies even if nothing has changed in the company’s operations since the last update. The FMCSA uses the data from the MCS 150 to assess safety trends, support enforcement actions, and assist in compliance, safety, and accountability programs.
Why You Can’t Skip Your MCS 150 Update
Failing to complete your MCS 150 update on time can lead to serious consequences:
- USDOT number deactivation: Your USDOT number can be deactivated, suspending your ability to operate legally.
- Civil penalties: The FMCSA may assess fines for non-filing that can reach up to $1,000 per day.
- Business interruptions: A deactivated USDOT number may affect insurance coverage, operating authority, and your overall reputation in the logistics and freight community.
Staying on top of your MCS 150 form update protects your business, enhances credibility with brokers and shippers, and ensures smooth operations year-round.
When Is Your MCS 150 Update Due?
The deadline for your biennial MCS 150 update isn’t tied to the date you first received your USDOT number. Instead, it’s calculated based on the last two digits of your USDOT number:
- The second-to-last digit determines whether you file in odd or even years.
- The last digit determines the calendar month the update is due.
For example, if your USDOT number ends in 34, you will file your MCS 150 update in April of an even-numbered year.
