Zorluk: OrtaSteering Techniques

An unexpected road obstruction forces a commercial motor vehicle driver to quickly steer onto the paved shoulder to prevent a collision. Once the vehicle has safely cleared the obstacle, which technique must the driver use to return to the travel path safely?

  1. A
    Apply firm service brake pressure while holding the steering wheel at its current angle to rapidly scrub off speed before returning.
  2. Countersteer immediately in the opposite direction without applying the brakes to re-align the vehicle with the travel lane.Cevap
  3. C
    Increase the steering angle sharply to force the vehicle around before attempting to recenter the steering wheel.
  4. D
    Release both hands from the steering wheel momentarily to let the power steering mechanism automatically self-center the front tires.

Cevap

Countersteer immediately in the opposite direction without applying the brakes to re-align the vehicle with the travel lane.
According to official commercial driving standards, when performing an evasive maneuver, a driver must turn only as much as needed to clear the hazard and countersteer immediately in the opposite direction without braking to re-align the vehicle safely.

Adım Adım Çözüm

1
Clear the obstacle using only the necessary amount of steering input without applying the brakes.
The commercial vehicle avoids the immediate road hazard without locking its tires or inducing a skid.
Applying brakes while turning can lock the wheels and cause total loss of directional steering control.
2
Countersteer smoothly and immediately in the opposite direction as soon as the hazard is cleared.
The vehicle re-aligns with the roadway and stays within its intended path of travel.
Immediate countersteering stops lateral momentum and prevents the vehicle from traveling off the roadway or rolling over.
