Trucking companies and contractors are required to have a Department of Transportation (DOT) number affixed to the sides of their trucks. Trucks must have these numbers before they can begin transporting materials, and any new company or carrier has to apply for one before it can send vehicles out on the road.

Every two years, or biennially, the information associated with this number must be updated. That’s done by filing an MCS-150. This form gives the government the most current information on your fleet and your company. It ensures that the data available is current and accurate.

What Happens If You Don’t Update Your DOT Number With the MCS-150?

If you fail to update your MCS-150 in a timely and accurate fashion, you face a fine of up to $1,000 per day. Additionally, your DOT number may be deactivated, which could cause disaster for your company, possibly shutting down operations.

What is an MCS-150?

The MCS-150 functions as an update to your DOT number. It’s essential that trucking companies fill out their MCS-150 forms correctly to ensure the Federal Motor Carrier Safety Administration has the right information to tally safety scores based on its compliance, safety, and accountability measurement system.
