How to Secure a DOT Number for Your Truck

Navigating the process of obtaining a Department of Transportation (DOT) number for your truck can seem daunting. However, it can be a straightforward process with the right information and guidance. This article will provide a step-by-step guide on securing a DOT number for your truck, ensuring you meet all requirements and regulations.


Step 1: Determine the Need for a DOT Number

The initial step involves determining whether your truck requires a DOT number. Not all carriers need one, but most do. If your truck is engaged in interstate travel, operates vehicles weighing more than 10,000 pounds, transports 9 to 15 passengers (including the driver) for compensation, transports 16 or more passengers (not for compensation), or transports hazardous materials, you will need to file a DOT application. If none of these conditions apply, you must only register with your local jurisdiction.

Step 2: Gather the Necessary Information

The DOT application is straightforward but requires some basic information about your business. You’ll need to provide details about your company operation, operation classification, cargo classification, hazardous materials classification (if applicable), number of vehicles, type of vehicles, ownership of vehicles, and driver status.

Step 3: Download the Appropriate DOT Application Form or File Online

There are three different DOT application forms; you must fill out the right one for your business. These forms include the MCS-150 (basic form for almost all carriers), MCS-150B (combination DOT number and hazardous materials application), and MCS-150C (combination DOT number and Intermodal Equipment Provider application). The system will choose the proper form if you file your DOT application online through the Federal Motor Carrier Safety Administration’s online portal.

Step 4: Complete and Submit Your Application

After filling out the appropriate form, you can mail it to the FMCSA or file your DOT registration online. There is no fee to file for your DOT registration.


Obtaining a DOT number for your truck involves determining your need for one, gathering the necessary information, downloading the appropriate application form, and submitting your application. While the process is straightforward, it requires careful attention to detail to meet all requirements. By understanding the process, you can navigate this process more effectively and ensure your trucking operations comply with all necessary regulations.
