- ASwing wide to the left before entering the intersection, and steer tightly around the corner into the nearest lane of the cross street.
- Keep the rear of the vehicle close to the right curb upon approach, proceed forward into the intersection past the corner, and swing wide into the cross street as the turn is completed.Cevap
- CPosition the vehicle straddling the center line well in advance of the corner, then turn directly across the apex of the curb.
- DMove into the oncoming traffic lane prior to the intersection to maximize the turning arc, then steer sharply right into the destination lane.
Cevap
Keep the rear of the vehicle close to the right curb upon approach, proceed forward into the intersection past the corner, and swing wide into the cross street as the turn is completed.
The correct method for making a tight right turn in a commercial motor vehicle is the button-hook maneuver. By keeping the rear of the vehicle close to the right curb during approach, the driver prevents other motorists from attempting to pass on the right. Proceeding deep into the intersection before turning allows the front wheels to swing wide into the cross street, ensuring that off-tracking rear wheels safely clear the corner curb without climbing the sidewalk or striking roadside obstacles.
