What Does GVW Mean for Truck Markings?
GVW stands for gross vehicle weight. An optional GVW decal is not a manufacturer's weight-rating label and does not replace vehicle registration records. Confirm which weight your customer or contract wants displayed.
Ontario's exterior marking rule is the owner's name on both sides of every commercial motor vehicle, attached or painted in a clearly visible position. HTA s. 103(1) sets no letter size and does not require GVW lettering.
When Do Fleets Choose GVW Lettering?
Fleets add optional GVW lettering when a customer, contract or yard asks for it, or when another jurisdiction requires a marking. Confirm that jurisdiction's rule before ordering; Ontario does not set an exterior GVW display requirement.
Customer or Contract Specifications
Ask for the exact weight, units, wording, size and placement requested. These are specifications for the optional marking, not Ontario GVW display law.
Yard Identification
If a yard asks for a visible weight reference, confirm what it needs on each vehicle before choosing lettering.
Operations Outside Ontario
Check the rules of each jurisdiction where the vehicle operates. An Ontario guide cannot establish the marking requirements elsewhere.

If your customer or contract asks for GVW, confirm its specification before selecting decals. We found no Ontario GVW exterior rule setting letter height, wording, units, colour, placement or material.
Which Weight Should an Optional Marking Show?
Do not choose a value from a typical truck-weight table. Confirm whether your customer or contract asks for registered gross weight, a vehicle rating or another weight reference, then use the appropriate vehicle record. Ontario does not impose a GVW exterior display rule requiring lettering to match the MTO registration.
Where Reg. 587 (Equipment) relies on the vehicle's weight rating, it points to the manufacturer's compliance label or, if the label is missing or illegible, a manufacturer document carried by the driver. An optional exterior decal is not a substitute for that record.
Common Mistakes When Ordering Optional GVW Lettering
Check these details if your customer or contract asks for GVW:
- Treating optional GVW lettering as an Ontario legal display requirement
- Confusing the requested weight reference with the manufacturer’s weight rating
- Ordering before confirming the customer’s requested value, units and wording
- Assuming a customer’s placement or material specification applies in every jurisdiction
- Treating an exterior decal as a replacement for vehicle records or the required owner-name marking

Frequently Asked Questions
Does Ontario require GVW lettering on a truck?
GVW lettering is optional in Ontario. We found no Ontario rule requiring gross vehicle weight or registered gross weight on the exterior. HTA s. 103(1) requires the owner's name on both sides of every commercial motor vehicle in a clearly visible position; it sets no letter size.
Does GVW need to be in pounds or kilograms in Ontario?
We found no Ontario exterior GVW display rule prescribing units or a format. If your customer, contract or yard asks for GVW lettering, confirm the weight and units they want before ordering. Check any other jurisdiction separately.
Can I use a magnetic GVW sign?
We found no Ontario GVW display rule prescribing permanent decals or banning magnetic GVW signs. If a customer or contract asks for a marking, confirm the accepted material and placement with them. Another jurisdiction may have different rules.
What happens if my GVW decal is faded or damaged?
A faded optional GVW decal is not a breach of an Ontario GVW display rule we found. If your customer, contract or yard requires readable lettering, replace it to meet that specification. Keep the required owner-name marking clearly visible.
Do I need a separate GVW decal for my trailer?
We found no Ontario rule requiring exterior GVW lettering on either the truck or trailer. If your customer or contract asks for a marking, confirm which vehicle to mark and whether they want a vehicle or combination weight. Check other jurisdictions separately.
What if I change my registered weight class?
We found no Ontario GVW display rule requiring a decal update after a registration change. If you choose to show a weight, review the optional lettering against the current value your customer or contract asks you to display. A decal does not replace registration or weight-rating records.
