Question

Difficulty: MediumSteering Techniques

A driver spots a fallen ladder blocking the travel lane and decides to steer around it into an open adjacent lane without braking. What is the correct chronological sequence of steering actions required to safely complete this evasive countersteering maneuver without losing vehicle control?

  1. 1Secure a balanced two-handed grip on opposite sides of the steering wheel while keeping off the service brake.
  2. 2Turn the steering wheel smoothly only as much as necessary to redirect the front of the vehicle past the hazard.
  3. 3Turn the steering wheel in the opposite direction immediately upon clearing the hazard.
  4. 4Straighten and center the steering wheel to stabilize the vehicle within the newly occupied lane.

Answer

The proper sequence begins with securing a balanced two-handed grip without braking, followed by turning the wheel just enough to clear the obstacle, immediately countersteering in the opposite direction once clear, and finally centering the steering wheel to stabilize the vehicle in the new lane.
Safe emergency steering requires full physical hand leverage before initiating motion, followed by minimal necessary steering around the obstruction, an immediate countersteer to catch the vehicle's momentum, and final centering to stabilize straight-line tracking.

Step-by-Step Solution

1
Ensure both hands grip opposite sides of the steering wheel and stay off the foot brake.
Maximum steering control is maintained and wheel lockup is avoided.
Braking during an evasive steer can lock the steer wheels and cause an unrecoverable skid.
2
Rotate the wheel smoothly to redirect the vehicle around the hazard into the adjacent lane.
The front of the vehicle moves laterally into clear pavement.
Limiting steering input to the minimum necessary keeps the vehicle stable and upright.
3
Steer firmly in the opposite direction as soon as the hazard is cleared.
Lateral vehicle momentum is arrested before crossing out of the target lane.
Countersteering is essential to prevent rollover, jackknifing, or leaving the roadway.
4
Bring the steering wheel back to center position once the vehicle is parallel in the lane.
The vehicle continues straight in the center of the lane.
Neutralizing the steer angle stabilizes tracking and completes the maneuver safely.
