Difficulty: MediumSpace Overhead

While navigating a commercial vehicle through a multilane city corridor, you observe low-hanging tree branches and utility service cables drooping over the right curb and edge of the pavement. What is the most appropriate driving practice to maintain safe overhead clearance?

  1. Move closer to the center of the street or utilize an inner lane when traffic conditions safely permit.Answer
  2. B
    Hug the right curb closely so passing traffic on your left has maximum room to maneuver.
  3. C
    Maintain your position along the pavement edge while increasing speed to pass beneath the hazards quickly.
  4. D
    Straddle the center line into oncoming traffic lanes without checking for opposing vehicles.

Answer

Move closer to the center of the street or utilize an inner lane when traffic conditions safely permit.
Commercial driver safety principles dictate that when tree branches or utility wires hang low along the right edge of a roadway, the driver should drive closer to the center of the lane or use a more central lane when traffic allows. This prevents the upper edges and corners of the trailer from striking overhead obstructions.

Step-by-Step Solution

1
Identify overhead obstacles located along the right road margin
Recognized that tree limbs and utility cables hang lower near the curb and sidewalk than over the center of the roadway.
Overhead objects along road shoulders frequently sag into the path of tall commercial vehicles.
2
Select a safe vehicle lane position to maximize vertical and side clearance
Adjusted lane positioning toward the center of the roadway or shifted to an available inner travel lane after checking traffic.
Roadway crown and trimming practices provide significantly greater vertical clearance toward the center lanes.
