MCS-150 Biennial Update

Every commercial motor carrier and trucking company with a USDOT number is required by the FMCSA to file an updated MCS-150 form on a biennial basis (every two years). With a TCS Compliance Specialist, you’ll never miss an important update.

When to file an MCS-150 update

MCS-150 updates are mission-critical.

An MCS-150 update is required by the FMCSA every two years at a minimum to obtain and maintain your USDOT number.

In addition to submitting biennial MCS-150 updates, you’ll need to file an MCS-150 update if you have:

  • Changed your business address
  • Changed your company name
  • Changed your operating authority
  • Become a hazardous materials carrier
  • Added to or reduced the number of vehicles in your fleet
  • Made any other changes to your business

Any time you make changes to your trucking business and operations, you should file an MCS-150 update.

Why? The FMCSA uses the information you submit via the MCS-150 update to calculate your safety performance scores according to its new safety measurement system: Compliance, Safety, Accountability (CSA). Out-of-date or otherwise inaccurate data can negatively impact your safety scores and subsequently, your trucking business.

So keeping your company information up to date is mission-critical for keeping your trucking company in compliance and on the road.

Working with our Compliance Specialists, you’ll have access to a vast amount of experience and knowledge to help to navigate MCS-150 filings and updates, keeping your trucking business compliant and running successfully.

TCS has been awesome!

Started my transport business this year & I can truly say that if it wasn’t for this company & staff, I wouldn’t have made it through the DOT/MC process with any hair on my head!

The awareness to stay ahead of any setbacks would have been overwhelming

I’m a new Owner Operator and getting organized and ready to present myself as a business owner with the awareness to stay ahead of any setbacks would have been overwhelming if the team from TCS had not taken the reigns for me.

The company is a one stop service for USDOT, LLC, and other legal matters

Transportation Compliance Services is the best because their employees I spoke to (3 of them) knew their jobs flawlessly. I am very impressed. It also tells me that the management is top of the line because the employees are very professional. The company is a one stop service for USDOT, LLC, and other legal matters needed for a business. The best phone call I made, and they got me up and running. Thank you.
