CVOR Number on Truck: A Guide to Compliance

If you're a commercial vehicle operator in Ontario, you're likely familiar with the Commercial Vehicle Operator's Registration (CVOR) system. One crucial aspect of CVOR compliance is displaying your CVOR number on your truck. In this article, we'll break down the requirements and best practices for displaying your CVOR number, helping you avoid fines and penalties at MTO scales like Vineland and Fort Erie.

What is a CVOR Number and Why is it Required?

A CVOR number is a unique identifier assigned to commercial vehicle operators in Ontario. It's used to track a company's safety record and compliance with regulations. According to the Highway Traffic Act (HTA), all commercial vehicles with a gross vehicle weight rating (GVWR) over 4,500 kg must display their CVOR number on the vehicle. You can find more information on CVOR number requirements in our CVOR Number Requirements Guide.

How to Display Your CVOR Number on Your Truck

To comply with regulations, your CVOR number must be displayed on both sides of your truck, near the front, in a clearly visible location. The letters and numbers must be at least 30 mm tall and in a font that's easy to read. You can use our compliance lettering products to ensure your CVOR number is displayed correctly.
