USDOT Lettering Guidelines
US Department of Transportation Decal/Stickers need to be at least 2 inches in height and must contrast with the background. If your vehicle is white, the lettering should be dark. Your lettering should be visible from a distance of 50 feet away. We recommend using a minimum of 3 inch lettering just to be safe. Your company name, and location of which you are doing business out of must also be displayed on your vehicle. The decals should be on each side of the unit.
