What is the correct way to negotiate a steep descent in snow or frosty weather?

Engaging a lower gear early and using gentle braking is the correct strategy for negotiating a steep descent in snow or frosty conditions. When you shift to a lower gear, it enhances engine braking, allowing the engine to help control your speed without relying solely on the brakes. This is crucial on slippery surfaces, where hard braking can lead to skidding or losing control of the vehicle.

Gentle braking is essential because it helps maintain traction. Sudden or hard braking can cause the wheels to lock up, especially on icy patches, resulting in a loss of control. By combining a lower gear with gentle braking, you maintain better control over the vehicle, allowing for gradual deceleration and a smoother descent.

In snowy and icy conditions, managing speed and traction is vital to ensure safe navigation of descents. Using a high speed to maintain control, as suggested in one of the options, can lead to increased risk of skidding or losing control. Engaging a higher gear early might not provide sufficient engine braking, and using the handbrake can be dangerous, as it may cause the rear wheels to lock up, further increasing the likelihood of skidding. Hence, the best approach is to engage a lower gear early while braking gently to ensure safe navigation.
