Which gear should you be in while going downhill?

When driving downhill, being in a lower gear is crucial for maintaining control of the vehicle. Downshifting to a lower gear allows the engine to help control the vehicle's speed through engine braking. This means that the engine generates braking force as it resists the motion of the vehicle, which can reduce reliance on the brakes and help prevent them from overheating.

Staying in a lower gear while descending can also give the driver more responsiveness and control over the vehicle, particularly on steep declines. If the vehicle were in neutral, it would roll freely, which could lead to loss of control, and engaging a high gear would not provide adequate braking force, making it more challenging to manage the vehicle's speed. Thus, using a lower gear is essential for safety and control when traveling downhill.
