DOT Signs for Trucks
What Are DOT Signs for Trucks?
DOT signs for trucks are federally required identification markings that display a company’s USDOT number and other regulated information on commercial vehicles. These signs are mandated by the Federal Motor Carrier Safety Administration (FMCSA) and must be clearly visible on vehicles involved in interstate or intrastate commercial transportation.
If you’re starting a transportation business, adding vehicles to your fleet, or updating existing truck graphics, properly designed DOT-compliant truck signs are essential. Once your vehicle is registered with the FMCSA and assigned a USDOT (and, if applicable, MC) number, those details must be displayed correctly on both sides of the vehicle.
We produce custom DOT signs for trucks and fleets, including permanent vinyl lettering, printed DOT panels, magnetic DOT signs, and safety-related warning decals — all designed to meet current U.S. Department of Transportation regulations while matching your branding.
DOT Sign Requirements & What to Know Before Ordering
Before ordering DOT signs for your truck, you must first obtain a USDOT number (and an MC number, if required) through the FMCSA. You can apply for these registrations independently, or work with a professional service that specializes in commercial transportation compliance.
During registration, your business details, operating authority, and vehicle information are submitted to the FMCSA. Once approved, these numbers must be displayed exactly as required on your truck or commercial vehicle.
When ordering DOT signs for trucks, the following federal requirements must be met:
- DOT signs must be displayed on both sides of the truck or commercial vehicle
- Lettering must contrast clearly with the vehicle surface for high visibility
- Characters must be at least 2 inches tall and legible from 50 feet away
- Information must remain visible and readable at all times
- Some states require permanent markings, which may restrict magnetic signs
To ensure compliance and durability, we offer DOT signs in multiple approved formats, including:
- Die-cut vinyl truck lettering
- Printed DOT panels
- Magnetic DOT signs (where permitted)
- Safety and warning decals related to DOT regulations
