The maximum weight a truck can be is dependent on:
- Highway classification.
- Maximum registered gross vehicle weight for vehicles.
- Tire size and axle spacing.
The 63,500, CTP and Weight Classification map includes all weight classes in Saskatchewan including primary weight highways, 63,500 kg weight highways, 9-month primary weight highways, secondary weight. In addition, the map identifies bridge restrictions, restricted highways and the clearing the path corridor.
Don't Overload the Road Poster and Map
The axle load of a wheeled vehicle is the total weight felt by the roadway for all wheels connected to a given axle. Legal weights and dimensions are needed to balance the capacity and geometric capabilities of the infrastructure with maximum economic benefits while ensuring road safety. View the Don't Overload the Road Poster and Map.
For detailed information on axle loading, legal dimensions and weights , refer to The Vehicle Weight and Dimension Regulations, 2010.
The annual Truckers' Guide serves as a great reference for commercial vehicle operators travelling in Saskatchewan. It's designed to make it easier to understand which transportation organizations are responsible for the information a commercial driver needs.
Bridge and Structural Clearance Table
The Bridge and Structural Clearance Table outlines the vertical and horizontal clearance of structures on Saskatchewan highways.
- Schedule A (PDF) – Bridges unable to support any load exceeding the allowable gross weight or axle weights.
Road Restrictions and Increased Weights
When transporting goods and/or services in Saskatchewan, the maximum gross vehicle weight is dependent on highway classification.
Commercial truck limits and weight restrictions are in place on provincial highways at various times of the year. It is done to prevent damage to the surface or road bed. There are also opportunities to haul additional weight depending on weather and other factors.
High Clearance Corridor
High clearance highways make it easier to do business in Saskatchewan. It provides shippers and commercial carriers to transport over-dimension loads. These corridors allow goods to be trucked without the need to raise or temporarily cut utility lines and other structures.
The corridor runs from:
- Saskatoon to the Alberta border on Highway 7.
- Melville to Rosetown through highways 15 and 4.
- Saskatoon to Shellbrook through highways 12 and 40.
- Shellbrook to Christopher Lake through municipal roads 693 and 780 and highways 3 and 2.
There are many types of truck configurations including straight truck, tandem drive, tridem and twin steer combinations.
- The maximum allowable vehicle loaded weight is dependent on highway classification, maximum registered gross vehicle weight for vehicles, tire size and axle spacing.
- Maximum gross vehicle weights are necessary for the protection of bridges.
- Maximum weights on axles or axle groups are necessary for the protection of bridges and pavements.
- Maximum tire weights are necessary for the protection of pavements and roadbeds.
- Maximum dimensions are necessary for the protection of bridges, overpasses, etc. and to protect the other users of highways by allowing the safe travel of the general public.
- Internal dimension limits are necessary to ensure that vehicles are designed to achieve desired levels of stability.
- The information provides general conditions for over-length loads, over-width loads, over-height loads, over-dimension loads and travel time restrictions.
