USDOT Lettering for Truck Doors
Example · type yours
Cut vinyl lettering, pre-spaced on clear transfer tape. You get two sets: one for each door.
The rules (49 CFR 390.21): your legal or trade name and USDOT number on both sides of the truck, readable from 50 ft in daylight, in a color that contrasts with the door. Some states add their own rules: pick yours under “State requirements”.

USDOT lettering: details & FAQ
Cut vinyl lettering for both truck doors, spaced and sized for you. Pick your layout above, check the preview, and we cut exactly what you see.
What has to be on my truck?
Federal rules (49 CFR 390.21) ask for your legal or trade name and your USDOT number on both sides of the truck, readable from 50 feet in daylight, in a color that stands out from the door.
Some states add their own rules. Pick your state under “State requirements” above to see them.
What size letters should I pick?
The federal rule doesn't set a letter height, only that it's readable from 50 feet. 2 in letters work for most doors; 3 in letters read better on big trucks. Some states set a minimum (North Carolina asks for 3 in), and the designer warns you if yours does.
What do I get?
Two sets of lettering, one for each door, pre-spaced on clear transfer tape so every line stays straight when you put it on.
Can I add my MC number, city or GVW?
Yes. Pick a layout above that includes them, and they're cut in the same font and size.
How long does it last?
We cut from outdoor vinyl made by Oracal, TeckWrap and Roland. Expect 2–8 years, depending on how much sun and weather it gets. Holographic and chrome finishes may start to fade after about 2 years.
How do I put it on?
- Clean the spot with rubbing alcohol and let it dry. Apply when it's above 50°F.
- Tape the decal in place along its top edge to make a hinge.
- Flip it up, peel off the white backing, and lay it down from the top, pressing firmly with a credit card or plastic card.
- Peel the clear tape back slowly at a sharp angle. If a letter lifts, press it down and try again.
- Wait 24 hours before washing it.
Can I wash it? What about ice?
Yes, once it has had 24 hours to set. Never run an ice scraper directly over the decal.
Can I take it off later?
Yes, it peels off easily. Warm it with a hair dryer first and it comes off even easier.
What can I put it on?
Any smooth, clean surface: glass, painted metal, plastic, laptops, tumblers, toolboxes and walls. It won't stick well to textured surfaces. Once it's on, it handles cold weather.
When will it ship?
Orders ship in 1–2 business days. The designer shows your estimated arrival date, and shipping is free on decal orders over $25.
What if it arrives wrong or damaged?
We remake it for free. See our refund & remake policy.
