Driving in Adverse Weather Condition theory test questions
Staying safe in rain, ice, fog, snow and wind — where stopping and seeing get much harder. Practise 91 questions free, each with the correct answer and a plain-English explanation mapped to the Highway Code.
What you need to know
- Use dipped headlights in poor daytime visibility; fog lights only below 100 m.
- Braking distances roughly double in the wet and can be ×10 on ice.
- In fog, slow down and leave a bigger gap — you can't stop in the distance you can see.
Sample question
After a heavy rain fall, the motorway is wet and road spray is affecting visibility and overall driving conditions. You should
- ensure that your hazard lights have been activated.
- ensure that your dipped headlights are on.
- ensure that your front fog lights are turned on.
- ensure that your rear fog lights are turned on.
Why
Dipped headlights increase your visibility and are recommended for safe driving in dangerous weather conditions.
Common mistake
Leaving rear fog lights on after fog clears — they dazzle drivers behind and hide brake lights.
Exam tip
Tie each condition to its action: fog→lights+gap, ice→gentle inputs, rain→double the gap.
