Do You Need a USDOT Number for Your Business Operation?

Most motor carriers are required to have a DOT number. However, there are a few different scenarios that require commercial motor vehicles to have a DOT number.
Find out if you’re included here:

If you are involved in “interstate” commerce and fall into one of the following categories, you need a DOT number:

  • You have a vehicle with a weight rating, gross vehicle weight, or a truck and trailer combined weight rating of over 10,000 pounds or more, whichever is greater.
  • It is designed or used to transport more than 8 passengers (including the driver) for compensation.
  • It is designed or used to transport more than 15 passengers (including the driver) and is NOT used to transport passengers for compensation.
  • You have a vehicle used to transport types and quantities of hazardous materials, requiring the vehicle to be placarded regardless of vehicle weight.

You may be wondering what interstate commerce is.

It is when a motor carrier crosses state lines. If you cross state lines and fall within just one of the categories above, then the FMCSA requires you to have a DOT number.

Here are a few more scenarios that need a USDOT number

If you are involved in “intrastate” commerce, meaning you do not cross over any state or international borders and fall into one of the following categories:

  • You have a vehicle used to transport types and quantities of hazardous materials, requiring the vehicle to be placarded regardless of vehicle weight.
  • Certain states in the U.S. require their “intrastate” carriers to have a federal USDOT number even though the motor carrier does not cross state or international borders. Below is a link to the FMCSA’s state list, but you should always check with your base state for the most up-to-date information.

Other Considerations

If you plan to operate as a for-hire carrier in interstate commerce, you will likely need your Operating Authority in addition to obtaining a USDOT number. To learn more about Operating Authority, go here or call us at 972-232-2218.

Importance of Having a USDOT Number

A USDOT number is crucial for businesses operating commercial vehicles in interstate commerce. It allows regulatory authorities to monitor your safety record and compliance with federal regulations. Without it, you risk fines and operational disruptions. Additionally, it enhances your credibility and shows a commitment to safety and compliance. A DOT number is essential for smooth operations, avoiding legal issues, and building trust with clients and partners.

If I have multiple trucks, do I need a separate DOT number for each truck?

No, you only need one USDOT number. You will place that number on the side of all your commercial vehicles. USDOT numbers are assigned to each person to identify themselves with the FMCSA and are assigned to that person for life. The Department of Transportation states that a “person” includes individuals, corporations, partnerships, or other business organizations as authorized by state law.

Can I transfer my USDOT number to another person?

No, USDOT numbers are not transferable. They are assigned to only one person or business and remain assigned to that person forever.

Do I need a new DOT number if I change my company's business name or form of business?

If the business is the same and no change in ownership has occurred, a name change can be made without getting a new USDOT number. You would need to register the new name with your base state.
