What is the best method for stopping on a snow-covered road?

1. Brake hard

2. Keep the foot on the brake

3. Pump the brakes

4. Use the emergency brake

The correct answer is: Pump the brakes

Pumping the brakes is the best method for stopping on a snow-covered road because it allows for more controlled deceleration without locking up the wheels. When driving on slippery surfaces, such as snow or ice, the goal is to maintain traction and avoid skidding. By pumping the brakes, the driver can apply the braking force in a way that gives the tires brief moments to regain grip on the road between brake applications. This technique prevents the wheels from locking, which can lead to loss of control. Instead of a continuous application of pressure that can cause the vehicle to slide, pumping the brakes helps maintain steering control while gradually reducing speed. In contrast, hard braking could easily cause the tires to lose traction and skid, while continuously keeping a foot on the brake might lead to similar issues of losing control due to locked tires. Using the emergency brake in these conditions is not advisable as it could cause the rear wheels to lock up, leading to a spin. Thus, pumping the brakes stands out as the safest and most effective method for stopping on snowy roads.
