Where it is necessary to turn a power unit semi-trailer around on a highway where there is no hard surfaced intersection, you may use the following procedure. Use a guide whenever possible because you will be backing to your blind side.

• Well before the place where you wish to turn around, signal right, check mirrors, and position your vehicle in the right lane.
• Cancel the signal light, proceed past the intersection, and stop when the rear of the trailer is at least 9 m (30 ft.) from the intersection in a position that allows you to reverse safely.
  • If stopping within the driving lane, the vehicle must be positioned as close as practicable to the right side of the right driving lane.
  • If a shoulder exists and is suitable, all or part of the vehicle may be positioned on the shoulder, provided it can be used safely and will support the weight of the vehicle.
• Turn on four-way flashers and sound horn. Check for traffic.
• Begin backing up slowly. Start turning steering wheel to the left approximately 9 m (30 ft.) before the trailer reaches the approach.
• Continue backing manoeuver until the unit has cleared the intersection and is positioned in a straight line and stop. Turn off four-way flashers.
• Check for traffic.
• Signal for a left turn, check for traffic again and proceed to make a left turn onto the highway.
