Answers
Shift to a low gear before going down steep hills.
Maintain traction by following other vehicles closely.
Pump your brakes to keep them from freezing.
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 like snow or ice requires careful attention to maintain control and ensure safety. One effective way to navigate steep hills on these surfaces is to shift into a low gear. Here’s why this is important:
- Engine Braking:
Shifting to a low gear increases the engine’s resistance, which slows the vehicle naturally without relying heavily on the brakes. This reduces the risk of skidding or losing control caused by sudden braking on slippery roads. - Controlled Speed:
In a low gear, your vehicle moves slower, providing better traction and allowing you to react more effectively to changes in road conditions. - Braking Risks:
Excessive braking on snow or ice can cause wheels to lock, leading to a skid. By using a low gear, you minimize the need to brake frequently, keeping the tires in better contact with the surface.
Why the Other Options Are Incorrect:
- “Maintain traction by following other vehicles closely”:
Following vehicles too closely reduces reaction time. On icy roads, stopping distances increase significantly. If the vehicle ahead stops suddenly, you’re likely to collide with it. - “Pump your brakes to keep them from freezing”:
Modern vehicles are equipped with Anti-Lock Braking Systems (ABS), which handle braking on slippery surfaces automatically. Pumping brakes is unnecessary and could be less effective than steady braking. Brakes freezing is generally not a concern unless the vehicle is parked for an extended period in extreme cold.
Additional Tips for Driving on Snow/Ice:
- Drive slowly and smoothly, avoiding sudden movements.
- Increase the following distance to 6-10 seconds.
- Keep an emergency kit in your car with items like blankets, food, and a flashlight.
- Ensure your tires are suitable for winter driving and have adequate tread depth.
By shifting to a low gear, you enhance safety and maintain better control in challenging conditions.
