When operating a long commercial vehicle that requires extra clearance to negotiate a sharp right turn at an intersection, which procedure should the driver follow to safely manage off-tracking?
- ASwing wide to the left before initiating the turn to create a wide turning arc for the trailer.
- Keep the rear wheels close to the right curb during the approach and swing wide into the cross street only as the turn is completed.Answer
- CShift into the oncoming traffic lane well prior to reaching the intersection to avoid clipping the right curb.
- DCut the turn tightly across the corner curb to minimize the total time the combination vehicle occupies the intersection.
Answer
Keep the rear wheels close to the right curb during the approach and swing wide into the cross street only as the turn is completed.
The correct method for making a right turn in a long commercial vehicle is the button-hook technique: keep the rear of the vehicle close to the curb during the approach to block trailing traffic from passing on the right, and swing wide into the cross street only as the turn is completed to accommodate off-tracking.
