Reviewed by Calculator Editorial Team
This Ontario Truck Weight Calculator helps you determine legal weight limits for trucks operating in Ontario. It calculates gross vehicle weight, axle weight limits, and other important parameters based on vehicle configuration and load.
How to Use This Calculator
To use the Ontario Truck Weight Calculator:
- Enter the number of axles your vehicle has
- Select the vehicle type (tractor, trailer, or combination)
- Enter the total weight of your vehicle in kilograms
- Click "Calculate" to see your weight limits
The calculator will display your gross vehicle weight, axle weight limits, and whether you're within legal limits for Ontario roads.
Formula Used
The Ontario truck weight calculator uses the following formulas:
Gross Vehicle Weight (GVW): Sum of all weights on the vehicle
Axle Weight: GVW divided by number of axles
Legal Limit Check: Compare axle weight to Ontario's legal limits (varies by vehicle type)
These calculations follow Ontario's Vehicle Weight Limits Regulations.
Worked Examples
Example 1: Single Axle Truck
A truck with a single axle and a total weight of 12,000 kg:
- GVW = 12,000 kg
- Axle Weight = 12,000 kg / 1 = 12,000 kg
- Status: Exceeds Ontario's single axle limit of 10,000 kg
Example 2: Dual Axle Truck
A truck with two axles and a total weight of 24,000 kg:
- GVW = 24,000 kg
- Axle Weight = 24,000 kg / 2 = 12,000 kg per axle
- Status: Within Ontario's dual axle limit of 12,000 kg per axle
Weight Limit Comparison
| Vehicle Type | Single Axle Limit | Tandem Axle Limit | Gross Vehicle Limit |
|---|---|---|---|
| Tractor | 10,000 kg | 12,000 kg | 24,000 kg |
| Trailer | 10,000 kg | 12,000 kg | 24,000 kg |
| Combination | 10,000 kg | 12,000 kg | 36,000 kg |
Note: These are general limits. Actual limits may vary based on specific regulations and vehicle configuration.
