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