What is an MCS-150?

The MCS-150 is a form required by the Federal Motor Carrier Safety Administration (FMCSA) used for motor carriers to register and update their U.S. Department of Transportation (USDOT) number company record.

The basic information required in your MCS-150 includes, but is not limited to:

  • USDOT Number
  • MC Number
  • Carrier Mileage
  • Legal Business Name
  • Type Of Company Operations
  • Cargo Classification
  • Number Of Vehicles
  • Driver Information

How Often Does an MCS-150 Need to be Filed? What is it?

The FMCSA requires that all motor carriers update their MCS-150 every two years. Additionally, any changes to the company’s operations must be updated in the MCS-150, preferably in an immediate timeframe.

Changes that must be updated include:

  • Change To The Legal Business Name
  • Change To The Business Addresses
  • Change In The Number Of Trucks

The MCS-150 is a federally mandated form that allows the FMCSA to analyze and regulate a carrier’s overall safety performance. The information required in the MCS-150 form works together as a combined report of safety data collection.

The USDOT Number is unique to each company, allowing the carrier to be federally recognized and regulated for compliance with safety and inspection. The FMCSA uses each USDOT number to monitor the safety record of each company, which includes information on reported accidents, safety violations, and inspection issues.

When is the Deadline to File the MCS-150?

The due date for filing an MCS-150 is different depending on the carrier, and companies must submit their filings on time. The deadline is dependent on the last two digits of your USDOT number. Reach out to our expert compliance team at FMCSA.com for assistance with filing your MCS-150, updating any information, and confirming whether you are currently in compliance.

So, How do You File the MCS-150?

Filing the MCS-15O can be done digitally or through the mail. The FMCSA Online Registration System is the only platform for registering and making updates to current MCS-150 forms.

While the process may seem simple, many carriers lack the correct information or resources to file properly, leading to delays, fines, and even the deactivation of their DOT numbers. At FMCSA.com, we handle all the complex paperwork for you, allowing you to sit back and relax while the filing gets taken care of. Our team at FMCSA.com keeps you compliant, stress-free, and safe from any potential penalties.

What are the Penalties for Inaccurate or Missed Filings of the MCS-150?

Failure to update your MCS-150 can result in the immediate deactivation of your USDOT number, making it illegal for the operations of your commercial motor vehicles to continue. Civil penalties are also typically imposed, with fines up to $1,000 each day, maxing out at $10,000.

Regardless of whether your company has made updates to the information or not, the MCS-150 must be filed biennially.

The number one reason carriers fall out of compliance with regulations is that they fail to renew their MCS-150 by the deadline.
