Answers
Shift into a higher gear.
Take the vehicle out of gear.
Shift into a lower gear.
Ride your brakes to maintain a safe speed.
The Correct Answer and Explanation is :
The correct answer is: Shift into a lower gear.
Explanation:
When driving downhill, it is important to manage both your speed and the control of your vehicle. Shifting into a lower gear helps achieve this in several ways.
- Engine Braking: When you shift into a lower gear, the engine helps slow the vehicle down through a process called engine braking. This occurs because the engine’s resistance to the wheels turning in a lower gear slows the vehicle without relying solely on the brake system. Engine braking can significantly reduce the risk of overheating the brakes, especially on long or steep descents.
- Control and Stability: A lower gear gives you more control over your vehicle’s speed, making it easier to maintain a safe, steady pace downhill. It also allows for better response when navigating sharp turns or unexpected obstacles. By not over-relying on brakes, your vehicle’s handling becomes more predictable.
- Braking System Protection: Continuously riding your brakes downhill can cause them to overheat, leading to brake fade or complete brake failure. This happens because the brake pads lose their ability to generate sufficient friction when they get too hot. Shifting to a lower gear reduces the need to brake excessively, which helps preserve the braking system’s effectiveness.
- Transmission Safety: It’s important to note that while you should shift to a lower gear, it’s equally important not to go too low, which could cause the engine to over-rev. The goal is to select a gear that allows you to descend at a safe speed without putting unnecessary strain on your vehicle.
Shifting into a higher gear or taking the vehicle out of gear would not provide the necessary engine braking, and riding the brakes too much can compromise your vehicle’s safety. Therefore, shifting into a lower gear is the safest and most effective option when driving downhill.
