OTTAWA, ON – Canada’s transport ministers have approved plans to allow tractors with longer wheelbases.

The amendments to the federal Memorandum of Understanding, which governs weights and dimensions, will see the maximum tractor wheelbase increase to 7.2 meters from 6.2 meters for tractors pulling semitrailers. Tractors pulling B-trains will see allowable wheelbases increase to 6.8 meters from 6.2 meters.

The move is to allow extra space for emissions-related equipment and improve driver comfort, a spokeswoman for Transport Canada said.

The change was agreed to during a joint meeting in Toronto.

Provinces and territories now begin the process of introducing the changes to their respective weights and dimensions regulations.
