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.
