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

Negotiating a steep descent in snow or frosty weather requires careful control of the vehicle to prevent skidding and loss of traction. Engaging a lower gear early is crucial as it allows the engine to help slow the vehicle naturally, thereby reducing reliance on the brakes. This is particularly important in slippery conditions, as sudden or hard braking can lead to wheel lock-up and loss of control.

Using gentle braking in conjunction with a lower gear helps maintain traction and stability. It allows for smoother deceleration without overwhelming the tires' ability to grip the icy surface. This method helps to keep the vehicle under control, as the combination of engine braking and gentle foot braking helps in managing speed safely.

In contrast, certain approaches, such as engaging a higher gear early or driving at high speeds, increase the likelihood of losing control on a slippery surface. Using the handbrake can be dangerous in a descent as it might cause the rear wheels to lock up, leading to a potential spin. Thus, the strategy of using a lower gear and gentle braking is the most effective and safest approach when navigating steep descents in winter conditions.
