Which one of the following is NOT something that you could potentially strike or damage if the rear of your vehicle swings over the sidewalk?

The choice indicating that overhead wires are not something you could potentially strike or damage if the rear of your vehicle swings over the sidewalk is accurate because the action involves the end of the trailer extending outward, which is primarily a lateral movement. Overhead wires are suspended above the roadway and are typically higher than the height of most tractor-trailer units and their trailers when making a turn near sidewalks.

In contrast, pedestrians, street signs, and vehicles parked on the side are all at ground level or slightly elevated and are within the potential path of a swinging rear. When a vehicle swings out during a turn, it poses a risk to anything in close proximity on the sidewalk or next to the road. Therefore, the risk of colliding with overhead wires does not apply when considering the movement of the trailer’s rear end near sidewalks.
