Difficulty: EasyIce and Snow Conditions

You are driving in freezing winter weather and encounter ice on the road. By up to how many times can your overall stopping distance increase compared to dry conditions?

  1. A
    Up to 2 times
  2. B
    Up to 4 times
  3. Up to 10 timesAnswer
  4. D
    Up to 20 times

Answer

In icy conditions, stopping distances can increase by up to 10 times compared to dry road conditions.
Tyres have very little grip on icy surfaces, which severely reduces braking capability. The UK Highway Code states that in icy or snowy conditions, stopping distances can increase by up to 10 times compared to dry conditions.

Step-by-Step Solution

1
Identify the environmental road condition specified in the scenario.
The road surface is covered with ice in freezing winter weather.
Different adverse weather conditions have distinct stopping distance multipliers in the Highway Code.
2
Recall the official Highway Code stopping distance factor for icy surfaces.
Stopping distances on ice and snow can be up to 10 times greater than on dry roads.
Severe loss of tyre grip on ice drastically reduces braking efficiency.
