When it's necessary to turn around with a power unit semi-trailer on a two-lane highway, the following procedure is recommended. Use a guide whenever possible.

• Choose an intersection where the intersecting highway is built up with a solid base and wide shoulders. Ensure that there is unobstructed visibility in all directions.
• Traffic permitting - complete a left or right turn and stop your unit well off the highway.
• Check for traffic - when all four directions are clear, proceed to back straight across the highway until you are again clear and well off the main highway.
• Traffic permitting, complete a turn onto the main highway.
