Difficulty: Very hardSpace for Turns

When executing a right turn onto a narrow two-lane street, a commercial driver may need to temporarily cross the center line of the destination street to accommodate trailer off-tracking. If an oncoming vehicle advances to the intersection in that opposing lane during this maneuver, the commercial driver must stop and reverse the combination vehicle to clear the lane, because the commercial vehicle is occupying an oncoming lane.

Answer: Answer

Answer

The statement is False. A commercial driver must never back up in an intersection to clear a lane during a turn.
The statement is false. According to commercial driving standards, if you must cross into an oncoming lane to make a right turn and a vehicle approaches, you must hold your position. You should never back up, because you cannot see directly behind the trailer and risk hitting a vehicle that has pulled up behind you.

Step-by-Step Solution

1
Analyze the right-turn space management scenario involving a narrow destination street.
The tractor must cross the center line of the destination street to accommodate trailer off-tracking, which is a proper button-hook turn.
Keeping the trailer close to the right curb prevents dangerous right-side passing, even if it requires the tractor to temporarily enter the opposing lane.
2
Evaluate the traffic conflict created when an oncoming vehicle approaches.
The combination vehicle is blocking the oncoming vehicle's legal lane of travel.
The wide turning radius inherently requires occupying this space temporarily.
3
Apply CDL safety regulations regarding reversing in intersections to resolve the conflict.
The CDL manual explicitly prohibits backing up in this situation.
Reversing a tractor-trailer creates a severe blind-spot hazard, risking a collision with unseen vehicles directly behind the trailer.
