What They Don't Tell You
I already have CVOR lettering — what do I add for US trips?
Three things: (1) Your USDOT number on both sides, minimum 2 inch height. (2) Your MC number if you are a for-hire carrier (brokers, freight haulers). (3) Your GVWR in POUNDS — the US does not use kilograms. Yes, you need BOTH kg (for Ontario) and lbs (for the US) displayed. We include both weight formats in our cross-border kit.
Does my USDOT number go on both doors?
Yes. FMCSA 49 CFR 390.21 requires the USDOT number on both sides of the power unit, readable from 50 feet (15 metres) during daylight. The text must be in a colour that contrasts with the vehicle background. Same placement rules as your CVOR number.
What about TARE weight?
TARE weight (empty vehicle weight) is not federally required for display in either country, but some US states require it for weight-rated vehicles. If you are running into specific states regularly, check their DOT requirements. Ontario does not require TARE weight display.
What do US DOT officers look for at Lewiston-Queenston?
At the Lewiston-Queenston Bridge inspection facility, FMCSA officers conduct Level 1 North American Standard Inspections. They check: (1) USDOT number visible and correct. (2) MC number if applicable. (3) Company name matches registration. (4) Vehicle condition (brakes, lights, tyres). Missing USDOT lettering is an automatic out-of-service order — your truck does not cross until it is fixed. They do NOT accept magnetic signs.
I run into Quebec too — is it different?
Quebec uses the NSC (National Safety Code) system administered by SAAQ. Requirements are similar to Ontario but the carrier identification number format is different. If you hold an Ontario CVOR and a SAAQ permit, you need CVOR markings in Ontario and may need additional markings in Quebec. Our Quebec compliance guide covers the specifics.
Can I put all the numbers on one door decal?
Yes — and that is exactly what our cross-border kit does. One professionally laid out decal per door with CVOR number, company name, USDOT number, MC number, and GVW/GVWR in both kg and lbs. Clean, compliant, one application.

DOT Regulations Cross Border — Complete Breakdown
DOT regulations for cross-border trucking between Canada and the United States are governed by two separate regulatory frameworks that must both be satisfied simultaneously. Canadian carriers are regulated provincially (CVOR in Ontario under O.Reg 424/97, NSC numbers in other provinces) while the United States uses the federal FMCSA system under 49 CFR 390.21. Neither country accepts the other's markings as a substitute — you need both sets on every vehicle that crosses the border.
Key DOT Regulation Differences That Catch Canadian Carriers
The most common cross-border compliance failures stem from subtle regulatory differences. Canadian carriers displaying weights in kilograms only will fail US inspection — the FMCSA requires GVW/GVWR in pounds. Similarly, the minimum letter height differs: Ontario requires 50mm (2 inches) for CVOR markings, while the US requires 2 inches (50.8mm) — nearly identical but measured differently. The colour contrast requirement is stricter in the US: characters must be readable from 50 feet during daylight, compared to Canada's “clearly legible” standard.
DOT Cross-Border Enforcement at Major Crossings
Each major border crossing has different enforcement patterns. Lewiston-Queenston Bridge (Niagara) runs Level 1 CVSA inspections with FMCSA officers who specifically check USDOT number display and MC authority. Ambassador Bridge (Windsor-Detroit) focuses on hazmat compliance and ELD records. Pacific Highway (BC-Washington) is stricter on weight declarations due to different state weight limits. At all crossings, missing USDOT lettering results in an immediate out-of-service order — your truck does not cross until the markings are applied.
2026 DOT Cross-Border Regulation Changes
Starting January 2026, FMCSA requires all foreign-domiciled carriers (including Canadian) to maintain current MCS-150 filings in the FMCSA portal. Lapsed filings now trigger automatic USDOT number deactivation — meaning your number becomes invalid even if it's properly displayed on your truck. Additionally, new ELD mandate enforcement means paper logbooks are no longer accepted for any trip exceeding 160 km (100 miles) within US territory. Canadian carriers must ensure their ELD system is FMCSA-certified, not just Transport Canada approved.
