Trailer Identification Compliance Reference
Under O.Reg 424/97 s.3, trailers drawn by commercial motor vehicles must display the operator name and, where applicable, the CVOR number. The MTO Carrier Handbook requires these markings on both sides of the trailer in letters at least 50mm (2 inches) tall. Our 3, 4, and 6 inch options provide legibility from curb-side inspection distance.
