If you start to skid on a slippery surface, what should you do?

When you start to skid on a slippery surface, the best approach is to ease off the accelerator and the brake, which is why the correct answer encompasses both actions along with the understanding that maintaining control of the vehicle is crucial. Easing off the accelerator helps reduce speed gradually without abruptly changing direction, while easing off the brake prevents further loss of traction.

Putting the transmission in neutral is not advisable as it can lead to a lack of control over the vehicle, making it harder to steer. Addressing the skidding situation requires maintaining steering control rather than disengaging the engine. Therefore, the comprehensive approach of doing all of these things—easing off both the accelerator and the brake—ensures that the driver can regain control of the vehicle effectively.
