Difficulty: EasyFactors Affecting Braking Distance

Severe winter weather can drastically reduce tyre grip on the road surface. According to the Highway Code, in icy conditions, by up to how much can your braking distance increase compared to driving on a dry road?

  1. A
    Up to 2 times as far
  2. B
    Up to 4 times as far
  3. Up to 10 times as farAnswer
  4. D
    Up to 20 times as far

Answer

Up to 10 times as far
Ice significantly reduces the friction between the vehicle's tyres and the road surface. According to the Highway Code, this loss of grip can increase your braking distance by up to ten times compared to driving on a dry road.

Step-by-Step Solution

1
Identify the specific weather hazard described in the scenario
The road condition is icy, which provides extremely low tyre grip.
Different weather conditions have specific distance multipliers set out in the Highway Code.
2
Recall the official Highway Code multiplier for icy conditions
Stopping distances, specifically braking distance, can be up to ten times greater on ice than on dry tarmac.
Knowing this multiplier allows drivers to adjust their speed and following distance appropriately.
