DOT number requirements at a glance
Federal FMCSA rules apply to commercial carriers in every state, including Maine. Your USDOT number must be:
- Displayed on both sides of the power unit
- In a color that contrasts sharply with the vehicle
- Readable from 50 feet in daylight (letters at least 2″ tall)
- Shown as “USDOT 1234567” — the letters “USDOT” before your number
These are general federal standards. Maine intrastate carriers may have additional state requirements — tell us your state at checkout and we'll match them, or verify current rules with your state DOT/DMV.

Maine DOT decal FAQ
Do I need a USDOT number in Maine?
If you operate a commercial vehicle over 10,001 lbs, haul hazardous materials, or carry passengers for hire, federal law requires a USDOT number displayed on both sides of the vehicle — and many Maine intrastate carriers need one too. We cut yours exactly as it should read.
What size do USDOT decals have to be?
FMCSA rules require letters at least 2 inches tall, in a color that contrasts your truck, legible from 50 feet, with “USDOT” shown before the number. Our standard set meets those specs; we also cut 3″ and 4″ for larger trucks.
How fast can you ship decals to Maine?
We make every order in 1–2 business days and ship nationwide, so most Maine carriers have their decals in hand within a few days. Everything arrives weeded, taped, and ready to apply.
