Final answer:
If a vehicle starts to skid, the driver should ease off the gas pedal or brakes and steer in the opposite direction of the skid.
Step-by-step explanation:
If a vehicle starts to skid, the driver should ease off the gas pedal or brakes and steer in the opposite direction of the skid. This technique is known as countersteering and is used to regain control of the vehicle. When a vehicle starts to skid, the wheels have lost traction with the road surface, and applying brakes or accelerating can further destabilize the vehicle. By easing off the gas pedal or brakes and steering in the opposite direction of the skid, the driver can help regain traction and steer the vehicle back on track.
