USDOT & Truck Regulation Sizing
We recommend your USDOT & truck regulation numbers to be at least 2" inches in height. 3" inches is the golden standard for all lettering in the United States. We also recommend that your lettering is in a contrasting color from the color of your vehicle. Example: A black USDOT number on a white truck, or a white USDOT on a dark colored vehicle. Another thing to consider is displaying all of your essential information on your vehicle such as the location of which you are doing business out of, vehicle weight (GVW), and VIN number. If you have any questions, do not hesitate in contacting us!
