USDOT Decal (Sticker) Size Requirements
Your US Department of Transportation Decal/Sticker should be visible from at least 50 feet away. It should be clearly visible on both sides of the vehicle for law enforcement. We recommended the lettering to contrast with the color of the vehicle. A good practice is to display all of the regulation numbers along with your USDOT number, this makes business & passing through scales a lot easier.
