The maximum axle weight limits and maximum gross vehicle weight limits set out in this Section are for axles equipped with dual tires, except for steering axles. The maximum gross vehicle weight limit for a vehicle or combination of vehicles composed of axles equipped with single tires or a combination of single tires and dual tires is the sum of the maximum axle weight limits in Section C–Axle Weight Limits of Part 1–Vehicle Weight and Dimension Limits for the particular axles equipped with single tires or a combination of single tires and dual tires for a specified class of highway. The maximum gross vehicle weight limit of a vehicle or combination of vehicles equipped with single tires or a combination of single and dual tires must not exceed the maximum gross vehicle weight limit of a similar vehicle or combination of vehicles equipped, except for the steering axle, with dual tires for a specified class of highway. |

The maximum axle weight limits and maximum gross vehicle weight limits set out in this Section are for axles equipped with dual tires, except for steering axles. The maximum gross vehicle weight limit for a vehicle or combination of vehicles composed of axles equipped with single tires or a combination of single tires and dual tires is the sum of the maximum axle weight limits in Section C–Axle Weight Limits of Part 1–Vehicle Weight and Dimension Limits for the particular axles equipped with single tires or a combination of single tires and dual tires for a specified class of highway. The maximum gross vehicle weight limit of a vehicle or combination of vehicles equipped with single tires or a combination of single and dual tires must not exceed the maximum gross vehicle weight limit of a similar vehicle or combination of vehicles equipped, except for the steering axle, with dual tires for a specified class of highway. |

The maximum axle weight limits and maximum gross vehicle weight limits set out in this Section are for axles equipped with dual tires, except for steering axles. The maximum gross vehicle weight limit for a vehicle or combination of vehicles composed of axles equipped with single tires or a combination of single tires and dual tires is the sum of the maximum axle weight limits in Section C–Axle Weight Limits of Part 1–Vehicle Weight and Dimension Limits for the particular axles equipped with single tires or a combination of single tires and dual tires for a specified class of highway. The maximum gross vehicle weight limit of a vehicle or combination of vehicles equipped with single tires or a combination of single and dual tires must not exceed the maximum gross vehicle weight limit of a similar vehicle or combination of vehicles equipped, except for the steering axle, with dual tires for a specified class of highway. |

The maximum axle weight limits and maximum gross vehicle weight limits set out in this Section are for axles equipped with dual tires, except for steering axles. The maximum gross vehicle weight limit for a vehicle or combination of vehicles composed of axles equipped with single tires or a combination of single tires and dual tires is the sum of the maximum axle weight limits in Section C–Axle Weight Limits of Part 1–Vehicle Weight and Dimension Limits for the particular axles equipped with single tires or a combination of single tires and dual tires for a specified class of highway. The maximum gross vehicle weight limit of a vehicle or combination of vehicles equipped with single tires or a combination of single and dual tires must not exceed the maximum gross vehicle weight limit of a similar vehicle or combination of vehicles equipped, except for the steering axle, with dual tires for a specified class of highway. |

1 The maximum steering axle weight can be as high as 9100 kg for a vehicle or combination of vehicles if the load-carrying capacity of the axle, tires, and all other components is not exceeded and the tire loading does not exceed 10 kg/mm of width; however, the maximum gross vehicle weight limit will be based on a steering axle weight of 5500 kg.
2 The self-steering axle may be equipped with single tires with a minimum width of 365 mm, or with dual tires. The self-steering axle may be liftable, but the controls, whether remote or manual, to raise or lower the self-steering axle must be located on the semi-trailer only, except for a semi-trailer used to carry raw forest products where the control may be in the cab of the tractor. The self-steering axle may be automatically raised when the vehicle is reversing. The self-steering axle may be manually raised to provide emergency drive axle traction, but only if the controls to manually raise the self-steering axle do not activate unless the emergency 4-way flashers are activated, and the controls must include a device which prevents the raising the self-steering axle at any speed greater than 60 km/hr.
3 The self-steering quad axle semi-trailer must be equipped with a device that accurately displays the total weight on the self-steering quad axle in kilograms, or with a device and a table or chart from the combined use of which the total weight on the self-steering quad axle in kilograms may be readily and accurately obtained.
4 For roads listed in Schedule B to the Road List Regulations made under the Act, the maximum weight is 54 000 kg for 7 axles with a tridem axle spread of 3.0 m to less than 3.6 m, and 55 500 kg for 7 axles with a tridem axle spread of 3.6 m to 3.7 m.
5 Maximum quad axle weight is 26 000 kg.
6 Maximum quad axle weight is 18 000 kg.
