Do I Need to File MCS-150 / DOT Update? Requirements Explained for Truck Drivers

If you operate a commercial motor vehicle, you’ve probably heard of the MCS-150 form. But many truck drivers and carriers ask the same question: Do I actually need to file this form?

You’re not alone. The rules can be confusing, especially for new carriers, owner-operators, or businesses that don’t run every day. The good news is that understanding whether you need to file an MCS-150 or DOT Update, and when, is easier than it sounds. Let’s break it down in plain terms.

What Is the MCS-150 Form?

The MCS-150, also known as the Motor Carrier Identification Report, is a form required by the Federal Motor Carrier Safety Administration (FMCSA). It updates your company’s information, including:

• Legal business name and address

• USDOT number status

• Type of operation (interstate or intrastate)

• Vehicle count and mileage

• Cargo classification

The FMCSA uses this information to keep carrier records accurate and up to date.

Who Is Required to File an MCS-150 or DOT Update?

You must file an MCS-150 if you have a USDOT number, even if:

• You are not currently operating

• You only operate seasonally

• You have not hauled freight recently

• Your business information has not changed

Simply put, if you have a USDOT number, filing is required — no exceptions.

What If I’m Not Actively Running?

This is where many drivers get confused. Even if your truck is parked, your business is inactive, or you haven’t taken loads in months, FMCSA still requires an MCS-150 update. If you’re not operating, you should file the form and mark your status correctly instead of skipping it altogether.

Failing to file can result in:

• USDOT number deactivation

• Problems with roadside inspections

• Issues when trying to reactivate operations

  
  

How Often Do I Need to Update MCS-150 or DOT Update?

FMCSA requires updates every two years, even if nothing has changed. This is called the biennial update.

Your update is due based on the last two digits of your USDOT number:

• Odd number → file in odd-numbered years

• Even number → file in even-numbered years

Additionally, you must file an update anytime your company information changes, such as:

• Address or phone number

• Company name

• Number of vehicles

• Type of operation

What Happens If I Don’t File?

If you don’t file your MCS-150 on time, FMCSA can:

• Deactivate your USDOT number

• Flag your record as non-compliant

• Cause delays with insurance filings or audits

Getting back into compliance later often takes more time — and sometimes more money — than filing on time.
