While navigating a sharp bend on an unpaved gravel road, a driver turns the steering wheel, but the vehicle fails to turn and continues sliding straight toward the outer shoulder due to a loss of front-wheel traction (understeer). What is the primary, safest driver reaction to regain directional control?
- Ease off the accelerator pedal immediately and allow the front tires to regain grip before smoothly guiding the steering wheel along the curvature of the road.Answer
- BTurn the steering wheel sharply in the opposite direction of the turn while applying steady pressure to the accelerator to force the vehicle back into the lane.
- CDepress the brake pedal forcefully to lock all four wheels until the vehicle comes to a complete halt on the road shoulder.
- DMaintain the current speed while rapidly pumping the steering wheel back and forth between the left and right directions.
Answer
The driver should immediately ease off the accelerator pedal and refrain from sudden braking or aggressive steering turns until the front tires regain traction and directional control is re-established.
During a front-wheel skid (understeer), the front tires have exceeded their limit of adhesion. Releasing the accelerator removes driving torque and shifts vehicle weight forward to the front wheels. This restores grip, enabling the driver to gently steer the vehicle along its intended path.
