Never park your vehicle in a manner that would block other drivers' views of an intersection. Preferably park 153 m (500 ft.) or more away from an intersection when stopping for a break.

To ensure that your vehicle will stay in position when parked, the following precautions must be observed:

1. Set the parking brake(s). When towing a semi-trailer you should apply the spring brakes on both power unit and semi-trailer when parked.
2. When on a grade, place a manual transmission in the lowest forward gear if parked facing uphill, or reverse gear if parked facing downhill.
3. If the vehicle is equipped with a two-speed axle, the axle must be in low range.
4. If the vehicle is equipped with an auxiliary transmission, the transmission must be in low range.
5. If the vehicle is on a grade, turn the front wheels in the appropriate direction.
   • with curb

     downhill: Turn front wheels to the right.
     uphill: Turn front wheels to the left. (Allow vehicle to roll until front wheel touches curb.) block vehicle.

   • no curb
     when parking downhill or uphill with a straight truck, turn front wheels sharply to the right. Block the wheels. For a tractor trailer, leave the wheels straight, apply the parking brake and block the wheels.

6. Under no circumstances should you use the trailer hand valve to hold a parked vehicle which will be left unattended.
7. When a vehicle is parked on a highway, it must be illuminated to warn other motorists of an obstruction as follows:
   • If the vehicle is completely clear of the travelled section, not disabled, and will be parked for less than four hours - activate hazard warning lights.
   • If the vehicle intrudes into the travelled section, is disabled or will be parked for more than four hours, it is recommended to place flares or reflective triangles as follows:
     • One on the traffic side of and 4 paces (approximately 3 m or 10 ft.) from the stopped commercial vehicle in the direction of approaching traffic;
     • One at 40 paces (approximately 30 m or 100 ft.) from the stopped commercial vehicle in the centre of the traffic lane or shoulder occupied by the commercial vehicle and in the direction of approaching traffic; and
     • One at 40 paces (approximately 30 m or 100 ft.) from the stopped commercial vehicle in the centre of the traffic lane or shoulder occupied by the commercial vehicle and in the direction away from approaching traffic.
