Recovery vehicles (tow trucks) and vehicles rendering assistance on the roadside
Flashing lights should be used only when the recovery vehicle, or the vehicle in repair or tow is creating a hazard or obstruction on the highway. When in tow, temporary tail, brake and signal lights shall be at the rear of the vehicle in tow.
Even though the vehicle is equipped with flashing lights, the driver is not granted any special privileges and must respect all right of way rules and other provisions.
You should remove derelict or damaged vehicles from the highways so that they do not obstruct the free passage of other vehicles. You should also clean up any debris that may be laying on the highway as the result of a collision.
Extreme caution should be used if a tow line is required to be stretched across a highway. Serious collisions have resulted where precautions have not been taken or a flagperson not posted.
When towing another vehicle, such as a power unit semi trailer, where the overall length exceeds the maximum allowable length, the driver must obtain a permit.
Drivers must slow to 60 km/h when passing a tow truck or service vehicle stopped on the roadside with its amber or amber and blue lights flashing while it is rendering assistance to a disabled vehicle, unless the truck is on the opposite side of a divided highway.
