To reduce speed while going down a steep hill, what should you do?

Use the brake constantly
Use a lower gear
Shift to neutral
Turn off the engine

The correct answer is: Use a lower gear

Using a lower gear when going down a steep hill is advisable because it helps maintain control of the vehicle and reduces the risk of losing braking power. When you shift to a lower gear, the engine helps slow down the car through resistance, which is known as engine braking. This is particularly important on steep descents, where constant brake use can lead to overheating and reduced effectiveness of the brakes. In contrast, using the brake constantly can lead to brake fade, making them less responsive as they heat up. Shifting to neutral removes any engine braking power and can make the vehicle harder to control, as you have less ability to react to changes in speed and road conditions. Turning off the engine would also disable power steering and braking systems, significantly impairing your ability to maneuver the vehicle safely. Therefore, using a lower gear is the most effective and safest method to control speed on a downhill slope.
