The Canadian agency responsible for regulating the transportation industry has published a final rule mandating electronic stability control devices on newly built tractors.
Transport Canada published its final rule in The Canada Gazette II on June 14. The agency has previously stated that from 2005 to 2012 an average of 2,810 truck tractor collisions per year included a rollover or loss-of-control event, 819 of which caused injury and 70 of which caused fatalities.
The rule calls for the devices to be installed on all newly built, three-axle truck tractors with a gross vehicle weight in excess of 26,000 pounds (11,793 kgs). The ESC requirements will be phased in for heavy trucks, starting first with three-axle truck tractors, effective Aug. 1, for vehicles manufactured in the U.S. and effective Dec. 14 for tractors in Canada. It is expected to be phased into all targeted truck tractors and motor coaches by Aug. 1, 2019.
Vehicles manufactured prior to enforcement date do not need to be equipped with ESC.
ESCs are designed not only to help prevent rollovers that may occur without the truck striking a curb or other roadside object, but also to mitigate understeer or oversteer conditions that could lead to a loss of control.
In its report, Transport Canada estimated that the devices could prevent up to 30 collisions per year involving 2018 vehicles.
The mandate aligns Canadian vehicles with U.S. safety standards, which were published via a final rulemaking by the National Highway Traffic Safety Administration in June 2015. The U.S. rule also calls for electronic stability control systems to be installed on certain new tractors beginning Aug. 1, with the equipment becoming standard on all new heavy trucks and motor coaches by Aug. 1, 2019.
Vehicles manufactured prior to the coming-into-force date need not be equipped with ESC.
