When USDOT Numbers are Required and Where to Display Them

As the world’s leading fleet graphics provider, Signature understands the importance of compliance and branding for fleets, both nationwide and globally. One crucial aspect of fleet operation that often comes into play is the requirement for USDOT numbers and their proper display. In this article, we’ll delve into the specifics of when USDOT numbers are required and where they need to be displayed, along with key information on size requirements and placement.

Understanding USDOT Numbers

A USDOT number, issued by the U.S. Department of Transportation (USDOT), is a unique identifier assigned to commercial vehicles and carriers involved in interstate commerce. These numbers are crucial for regulatory compliance and safety monitoring purposes. While not all vehicles are required to display USDOT numbers, certain circumstances mandate their use.

When USDOT Numbers are Required

  1. Interstate Commerce: Vehicles engaged in interstate commerce, which involves transporting goods or passengers across state lines, typically require a USDOT number. This applies to commercial vehicles with a gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR) of 10,001 pounds or more.
  2. Intrastate Operations: Some states may also require USDOT numbers for vehicles involved in intrastate commerce, depending on state-specific regulations. It’s essential to check the requirements of individual states where operations occur.

Size Requirements for USDOT Numbers

The USDOT number must be displayed on the vehicle in a specific size to ensure visibility and compliance. According to USDOT regulations:

  • Height Requirements: USDOT numbers must be at least two inches in height on commercial motor vehicles.
  • Contrast: The numbers must be in a color that contrasts sharply with the background color of the vehicle.
  • Placement: The numbers should be displayed on both sides of the vehicle, preferably on the exterior portion of the vehicle’s power unit or cab.

Where to Display USDOT Numbers

Proper placement of USDOT numbers is crucial for compliance and visibility. Here are the key guidelines for displaying USDOT numbers:

  • Exterior of Vehicle: USDOT numbers must be prominently displayed on both sides of the vehicle, preferably on the cab or power unit. The numbers should be easily readable from a distance and not obstructed by any accessories or decals.
  • Size and Legibility: Ensure that the numbers meet the minimum height requirement of two inches and are clearly legible. Avoid placing them in areas where they may be obscured by dirt, debris, or other objects.
