Difficulty: HardEvasive Steering and Avoiding Collisions

A commercial driver is forced to steer the vehicle's right-side tires onto an unpaved shoulder to avoid a collision with an oncoming vehicle crossing the center line. Once the opposing vehicle has passed, what is the correct procedure for returning the commercial vehicle safely onto the paved roadway?

  1. A
    Maintain highway travel speed while easing the steering wheel at a very shallow angle so the tires gradually climb along the pavement edge.
  2. B
    Apply firm service brake pressure while turning sharply toward the pavement, keeping the wheel held in the turn until all axles are centered in the lane.
  3. Slow down, turn the steering wheel sharply toward the road to clear the pavement lip, and immediately counter-steer once both front tires mount the pavement.Answer
  4. D
    Steer further away from the road surface onto the soft ditch while pumping the brakes until the vehicle comes to a complete standstill.

Answer

Reduce speed, turn the steering wheel sharply toward the roadway to clear the pavement lip, and immediately counter-steer in the opposite direction once the front tires mount the pavement.
Returning safely from an off-road evasive maneuver requires slowing down first, turning sharply (about one-quarter to one-third turn of the wheel) to climb the pavement lip cleanly, and instantly counter-steering to prevent the vehicle from darting across the lane into opposing traffic.

Step-by-Step Solution

1
Hold the wheel firmly and stay off the brakes while straddling the pavement edge until speed is significantly reduced (around 20 mph if conditions permit).
Maintains directional stability and avoids skidding on split-traction surfaces.
Hard braking on loose shoulder material causes wheels to lock and slide.
2
Turn the steering wheel sharply toward the road surface (about one-quarter to one-third turn) rather than creeping back gradually.
The front tires climb over the pavement edge drop-off without rubbing or catching against the lip.
Gradual angles cause tire scrubbing, which can snatch the steering mechanism or pull the vehicle sideways.
3
Counter-steer immediately in the opposite direction as soon as both front tires mount the pavement surface.
The vehicle straightens out smoothly within the intended lane of travel.
Failing to counter-steer immediately will cause the heavy vehicle to shoot across the center line into oncoming traffic.
