DOT Number Stickers & Lettering for Ontario Trucks: USDOT Compliance Guide

If your commercial vehicles cross the US-Ontario border — through Fort Erie, Niagara Falls, Sarnia, or any other crossing — you need USDOT numbers displayed on every power unit. This guide covers FMCSA requirements, how to get a USDOT number, display rules, and compliant lettering products.

Who Needs a USDOT Number?

The FMCSA requires a USDOT number for any commercial vehicle:

• Operating in interstate commerce in the United States
• With a gross vehicle weight rating (GVWR) of 10,001 lbs or more
• Transporting hazardous materials requiring placards
• Designed to transport 9 or more passengers (including the driver) for compensation
• Designed to transport 16 or more passengers (including the driver) not for compensation

For Canadian carriers: Any truck crossing into the US for commercial purposes needs a USDOT number, regardless of whether it already has a CVOR certificate.

USDOT Number Display Requirements

FMCSA regulations (49 CFR 390.21) require:

Element	Requirement
USDOT Number	Both sides of the power unit, preceded by "USDOT"
Minimum Height	2 inches (5 cm)
Colour	Contrasting with background
Legibility	Readable at 50 feet during daylight
Legal Name	Company legal name or trade name on both sides
MC Number	If applicable, preceded by "MC"

USDOT vs MC Number: What is the Difference?

A USDOT number identifies the carrier for safety audits and inspections. An MC (Motor Carrier) number is your operating authority to transport regulated commodities for compensation. Not all carriers need both:

• USDOT only: Private carriers hauling their own goods
• USDOT + MC: For-hire carriers transporting goods for others
• USDOT + MC + CVOR: Ontario for-hire carriers operating in the US
