Should you normally drive in a low gear or in a high gear when the road is slippery?

You should normally drive in as high a gear as possible in slippery conditions. Doing so reduces the risk of the car losing traction, as the rate of acceleration decreases every time you change into a higher gear.

However, if you need to reduce your speed when driving down steep inclines it is better to drive in a lower gear as this allows you to slow down using engine braking, which reduces the risk of wheel lock and lost traction.
