The correct answer and explanation is:
The correct answer is: Shift to a low gear before going down steep hills.
Explanation:
Driving on slippery surfaces, such as snow or ice, requires special precautions to ensure safety. Here’s an explanation of why this is the correct answer, as well as why the other options are not advisable:
- Shifting to a low gear before going down steep hills: When driving on ice or snow, it’s crucial to maintain control of your vehicle at all times. Shifting to a low gear, often called engine braking, helps slow down the vehicle without relying solely on the brakes. This is important because, on slippery surfaces, applying the brakes too hard can cause the wheels to lock up, leading to loss of control or skidding. Engine braking in a low gear reduces the speed of the vehicle in a smoother and safer manner, which is especially important on steep hills where momentum can quickly get out of control.
- Maintain traction by following other vehicles closely: This is a dangerous practice. Following too closely (tailgating) is never advisable in any driving condition, but it’s even more hazardous on snow or ice. On slippery roads, stopping distances are much longer, and you may not have enough time to react if the vehicle ahead of you stops or loses control. It’s better to maintain a safe distance from other vehicles (at least 3-4 seconds), so you have enough space to react to any potential hazard.
- Pump your brakes to keep them from freezing: This idea is a misconception. Modern vehicles with anti-lock braking systems (ABS) are designed to handle braking in slippery conditions without the need to pump the brakes. In fact, pumping the brakes on vehicles with ABS can reduce braking effectiveness. On ice or snow, you should apply steady, gentle pressure to the brakes rather than pumping them. In vehicles without ABS, it’s better to apply steady pressure rather than pumping, as pumping can cause the vehicle to skid.
In summary, shifting to a low gear is the safest and most effective way to manage your speed on slippery slopes, whereas following too closely and pumping brakes can lead to accidents or loss of control.
