In this short video clip, we'll go over the basics for displaying and placing your USDOT & CA number outside of your commercial vehicle.
A few things to keep in mind is that your USDOT lettering must be visible from a distance of 50 feet, so you want to make sure the lettering is at least 2 inches high. It can be bigger. You must remember that the font you use must be an easy to read font and the color of the lettering must contrast with the color of your vehicle. If you have a white vehicle then dark lettering will be DOT compliant.
