Subject: Regulatory Registry – Amendments to O.Reg. 413/05, Vehicle Weights and Dimensions (VWD) for Safe, Productive, and Infrastructure-Friendly (SPIF) Vehicles

Ontario Heavy Vehicle Stakeholders,

The Ontario Ministry of Transportation would like to inform you and your members of potential amendments to Ontario Regulation 413/05, Vehicle Weights and Dimensions (VWD) for Safe, Productive, and Infrastructure-Friendly (SPIF) Vehicles.

The amendments include the following:


•                Eliminate the need for special vehicle configuration permits currently required to operate long wheelbase tractors with multi-axle semitrailers, longer saddlemounts, and semitrailers equipped with smart lift axles.

•                The same tire weight allowance for wide based single tires as to dual tires when mounted on single axles;

•                Loading of boats on stinger-steer auto carriers under the same weight and dimensional limits;

•                Modify the conditions to allow the use of an Emergency Lift Axle Override, so to lift the self-steering axle in emergency situations improving the general safety operation of the truck.

The above-note amendments are detailed in the regulatory registry posted here:



Comments posted to the regulatory registry must be submitted by the date indicated,June 1, 2019.

Once the comment period is closed, the Ministry will review comments reviewed toward considering adjustments to the proposed regulation, before moving forward toward implementation.

Please note that the for the Emergency Lift Axle Override in-cab controls, the regulation is proposed to reflect the following:

  • Subsection 5 (2) of the Regulation would be amended to reflect the requirement, if requested by the customer, for an Emergency Lift Axle Override control within the cab of the truck.
    • If the truck or tractor was built on or after January 1, 2020, the control is an emergency lift axle override control that meets all of the following conditions:
      • It allows the driver from the cab of the truck or tractor to lift, alter or deploy the weight on a self-steering axle of the truck or of any drawn trailer.
      • It is separate and independent from the 4-way flasher control.
      • The words “Emergency Lift Axle Override” appear adjacent to the control.
      • It activates the emergency 4-way flashers.
      • It only lifts, alters or deploys,
        • in the case of a tractor-trailer combination, the most forward self-steering axle of the semi-trailer, or
        • in the case of a truck, the self-steering axle or forced-steer auxiliary pusher axle.
      • It begins the lifting or altering of weight immediately upon activation.
      • It does not allow the axle to be lifted or its weight altered when the truck or vehicle combination is travelling at a speed over 60 kilometres per hour.
      • It fully deploys the self-steering axle,
        • immediately upon the vehicle stopping,
        • immediately upon the tractor power being turned off, and
        • within three minutes after the lifting or altering of weight.
