To make a left turn in a large vehicle it is recommended that you?

• A. Merge into the farthest right as soon as your turning arc is complete
• B. Ensure a wide enough turning arc to allow the vehicle to off-track on the left side without crossing the center line
• C. Use engine compression to control your speed during the turn
• D. Use a fixed hand steering method to maintain control of the vehicle

Answer: (B)

Safely turning a large vehicle hinges on accounting for off-tracking — the rear wheels don’t follow the front wheels exactly. On a left turn, the rear axle tends to swing to the left, so you need a wide enough turning arc to accommodate that off-track without crossing the center line. This keeps the rear end from intruding into the oncoming lane as you complete the turn. The other options don’t address that turning geometry: moving to the far right early isn’t appropriate for a left turn; using engine compression to control speed isn’t a reliable or proper method for steering; and fixed hand steering doesn’t provide the necessary control for a large vehicle maneuver.
