USDOT Truck Lettering Decal Sticker Sizing Regulations

We recommend displaying your US DOT regulation numbers on both sides of your truck or vehicle. The USDOT lettering must be visible from at least 50 feet away and the lettering itself should be a minimum of 2 inches in height. We also recommend the USDOT number color to contrast from the truck color. If your truck is black then we recommend something light. 

It is very important to display all of your regulation numbers outside of your truck to save time when you go through truck scales or when you get stopped by the authorities.
