The Big and the Heavy: What you need to know about overweight trucks in Canada
Do you have questions on how to avoid or deal with driving an overweight truck in Canada? It can have serious consequences if your commercial vehicle is deemed overweight by the regulations of the jurisdiction where you plan to operate. When a vehicle is overweight, permits are issued for trucks and loads that exceed the weights set by the ruling transportation body of each province and permits are valid typically for highways only. If you want to drive on municipal roads, you may be required to get additional permits or permission directly from that municipality.
What you need to be aware of will depend on the province in which you are planning to operate. The maximum weight allowed for commercial vehicles in Canada depends on the registered gross vehicle weight (RGVW), the axle configuration and spacing, and the type of tires.
For example, in British Columbia, The maximum weight allowed for commercial vehicles in BC depends on the licensed gross vehicle weight (GVW), the gross combination vehicle weight (GCVW), the axle configuration and spacing, and the type of permit. The maximum GCVW for term permits in BC is 64,000 kg.
Checking your weight and dimensions
There are a few ways to estimate your vehicle’s weight. You can look up your vehicle by registration number or VIN or you can look in your vehicle’s manual or even call the manufacturer. The best way to get your vehicle’s weight is to weigh your vehicle using portable scales under each axle or by driving onto a scale. The rules, laws, and regulations for oversize in Canada are extensive and informative and are designed to ensure the safety of drivers, other road users, and the infrastructure.
The maximum legal limits allowed for height, width, and length are:
- Maximum width – 2.6 metres (vehicle and load)
- Maximum height – 4.15 metres (vehicle and load)
- Maximum length – 12.5 metres (single vehicle including load)
- Maximum length - 14.65 metres (semi-trailer including load)
- Maximum length (combination) - 23metres (combination vehicle and loads)
If your combination exceeds these dimensions, an oversize permit would be required.
Are you eligible for an overweight permit?
In Canada, whether or not you need an overweight permit for your trucks depends on the province you will be crossing and on many other different variables like axle spreads, specific axle weights, tire size, etc. This is why it is important to include as many details as possible when you fill out the application.
You are eligible to apply for a permit if your vehicle or load cannot be reduced because it:
- Could not be used for its intended purpose or function; and/or
- Would require more than eight work hours to dismantle.
You will not be eligible for a permit if your load is :
- Vehicle, load, or combination will be overweight, and your load is made up of more than one item;
- Vehicle or load is over height, over width, or overlength because of the way you have loaded it. For example, items are stacked in a way that creates unnecessary additional height, width, or length.
- Vehicle or load is overlength, your load is made up of more than one item, and the overhang of your load to the rear exceeds 4.65 metres from the centre of the rear-most axle
How do I get an oversize/overweight permit?
The process of getting a permit for an overweight truck may vary depending on the jurisdiction and the type of permit you need. You need to apply to the transportation authority of the province or territory where you plan to travel. The requirements, fees and conditions may vary depending on the type and size of your load and vehicle. You can find more information and online application forms on the websites of each province or territory.
The federal government does not issue permits for oversized or overweight vehicles.
How long is your permit valid?
Permits are good for a single trip meaning that if you cross from one province into the other and come back to your home province that permit is not valid anymore. For example, if you are based in Ontario, you deliver goods in Quebec and come back to Ontario, the permit you were issued is no longer valid. On the other hand, permits do have a validity period to complete your single trip and it can range from 48 hours to 10 days depending on which province the permit was issued in. Always read your permit to ensure you’re complying with its conditions.
Key to remember: To avoid overweight issues, plan your route to avoid roads or bridges that have weight restrictions, make sure your load is evenly distributed, obtain the proper permits, and most importantly follow the safety standards and regulations in your jurisdiction.
