Understanding the MCS-150 Form: A Complete Guide for Motor Carriers

If you operate a commercial motor vehicle in the United States, staying compliant with FMCSA regulations is critical. One of the most important requirements for motor carriers, brokers, and freight forwarders is filing the MCS-150 form, also known as the Motor Carrier Identification Report.

MCS-150

This guide will explain what the MCS-150 is, why it’s required, how often it needs to be updated, and why carriers should seek professional help to avoid costly mistakes.

What Is the MCS-150 Form?

The MCS-150 form is an official filing with the Federal Motor Carrier Safety Administration (FMCSA). It provides updated details about your company’s operations, such as:

  • Legal business name and address
  • USDOT number
  • Fleet size and vehicle information
  • Types of cargo transported
  • Mileage from the previous year
  • Company contact information

The FMCSA relies on this data to track safety performance, monitor compliance, and ensure carriers operate safely on U.S. highways.

Who Needs to File the MCS-150?

The MCS-150 form is required for:

  • Interstate motor carriers operating commercial vehicles across state lines.
  • Hazardous material carriers within a state, if transporting quantities that require a safety permit.
  • Brokers, freight forwarders, and cargo carriers registered with the FMCSA.

If your company has an active USDOT number, filing the MCS-150 is mandatory.

How Often Do You File the MCS-150?

The FMCSA requires carriers to file a biennial update every two years, even if no business details have changed. The due date is based on your USDOT number:

  • The second-to-last digit tells you whether you file in an odd or even year.
  • The last digit tells you the month your filing is due (1 = January, 2 = February, etc.).

For example, a USDOT number ending in 25 must update in May of every odd year.

Failing to update your MCS-150 can result in your USDOT number being deactivated and may trigger civil penalties.

Why Is the MCS-150 Important?

Filing the MCS-150 is more than a paperwork requirement—it directly impacts your safety and reputation in the trucking industry. The FMCSA uses your MCS-150 data to calculate safety measurement system (SMS) scores, which affect inspections, audits, and even business opportunities.

Some key reasons to stay compliant include:

  • Avoiding fines and penalties from the FMCSA.
  • Preventing USDOT deactivation, which can shut down your business operations.
  • Maintaining accurate safety scores, which insurance companies and shippers review.
  • Protecting your company’s reputation with customers and partners.
