Difficulty: EasySpace Overhead

While driving on a city street, a commercial driver notices low-hanging tree branches extending over the right side of the travel lane. Which of the following is the safest procedure for the driver to manage overhead space?

  1. Steer closer to the center of the lane or safely shift toward the left lane to avoid contact with the branches.Answer
  2. B
    Move further onto the right shoulder so the branches make contact only with the mirrors and rub rail.
  3. C
    Increase driving speed so that vehicle momentum bends the branches out of the way without snagging.
  4. D
    Maintain a close following distance behind a smaller passenger car to let it clear the branches ahead.

Answer

Steer closer to the center of the lane or safely shift toward the left lane to avoid contact with the branches.
Tree branches and roadside vegetation often hang lower near the curb and right edge of the street. Safe drivers keep their vehicle closer to the center of the lane or change to an open left lane to prevent branches from catching or damaging the upper structure of the trailer.

Step-by-Step Solution

1
Identify the overhead hazard on the roadway.
Low-hanging tree branches are located on the right side of the travel lane.
Commercial motor vehicles are tall and vulnerable to tree branches and overhead utility lines along curbs and roadside edges.
2
Adjust lane positioning safely to maintain overhead clearance.
Position the vehicle toward the center of the lane or move into a left lane when traffic allows.
Maintaining adequate clearance prevents physical damage to the trailer roof, side panels, and marker lights.
