An articulated transport vehicle is preparing to make a sharp 90-degree right turn onto a narrow side street with limited curb clearance. To prevent the trailer off-tracking from clipping the curb while avoiding trapping other road users on the right, which procedure should the driver follow?
- ASteer toward the center of the road early in the block to widen the turning radius before reaching the corner.
- Stay close to the curb line while approaching the corner, and swing out into the cross street only as the turn is completed.Answer
- CIncrease road speed entering the intersection to generate outward momentum that pulls the trailer axles away from the curb.
- DTurn sharply at the curb line and rely on backing up if the trailer tires make contact with the sidewalk.
Answer
Stay close to the curb line while approaching the corner, and swing out into the cross street only as the turn is completed.
To manage space safely during a right turn, a commercial driver should maintain a position close to the right curb on approach to prevent other vehicles from attempting to pass on the right. If extra room is required to accommodate trailer off-tracking, the vehicle should swing wide into the intersecting street as the turn is completed (a button-hook turn), rather than swinging wide to the left beforehand (a jug-handle turn).
