Yes. All of our decals meet or exceed FMCSA requirements for size, color,font, and reflectivity. We stay up to date on all regulations so you canstay compliant with confidence.

Federal regulations (FMCSA) require your USDOT numbers to be legible from a distance of 50 feet during daylight hours. To meet this standard, the lettering must be at least 2 inches in height.

The law requires the lettering to sharply contrast with the background color of your vehicle. If your truck is white or light-colored, choose black. If your truck is dark, choose white or highly reflective light colors.

We offer a variety of highly legible, clean block fonts (such as Arial Bold and Impact) that guarantee compliance. We avoid script or cursive fonts, as they do not meet federal readability requirements.

Most custom decal orders are processed, cut, and shipped within 1–2 business days. You will receive a tracking number as soon as your order leaves our facility.
