DVSA Adverse Weather Driving 2 — Questions and Answers
Question 1: What should you do if you are dazzled by the headlights of an oncoming vehicle?
- Flash your headlights back at them
- Look at the left-hand edge of the road and slow down or stop if necessary (Correct answer)
- Speed up to pass them quickly
- Close your eyes briefly
Correct answer: Look at the left-hand edge of the road and slow down or stop if necessary
If dazzled by oncoming headlights, avoid looking directly at them. Instead, look towards the left-hand edge of the road (the nearside kerb) and slow down or stop if necessary until your vision recovers.
Question 2: What gear should you use when driving downhill in snow or ice?
- The highest gear possible
- A low gear to help engine braking (Correct answer)
- Neutral to save fuel
- Reverse gear
Correct answer: A low gear to help engine braking
When going downhill in snow or ice, use a low gear and avoid braking harshly. Engine braking helps maintain a controlled speed without relying on the brakes, which could cause a skid.
Question 3: How should you demist your windscreen quickly?
- Open all windows fully
- Use the vehicle's heater and demist controls directed at the windscreen (Correct answer)
- Wipe it with your hand while driving
- Pour hot water on the outside
Correct answer: Use the vehicle's heater and demist controls directed at the windscreen
Use your heater and air conditioning directed at the windscreen to demist it. The air conditioning removes moisture. Many vehicles have a dedicated demist setting that maximises airflow to the screen.
Question 4: What should you do when driving through a ford or flooded section of road?
- Drive through as fast as possible
- Drive through slowly in a low gear, keeping engine revs high (Correct answer)
- Always turn around and find another route
- Switch off your engine and coast through
Correct answer: Drive through slowly in a low gear, keeping engine revs high
Drive through slowly in a low gear to avoid creating a bow wave that could flood the engine. Keep the engine revs high to prevent water entering the exhaust. Test your brakes afterwards.
Question 5: What is the main danger of driving too close to the vehicle in front in wet weather?
- Reduced fuel economy
- Spray from their tyres can severely reduce your visibility (Correct answer)
- Their exhaust fumes are concentrated
- It damages your paintwork
Correct answer: Spray from their tyres can severely reduce your visibility
In wet weather, spray thrown up by the vehicle ahead can drastically reduce your visibility. Keeping a greater following distance reduces spray and gives more time to react.
Question 6: When should you use your full beam headlights?
- On well-lit urban roads
- On unlit roads when no other vehicle is ahead or approaching (Correct answer)
- Whenever driving at night
- In fog for maximum visibility
Correct answer: On unlit roads when no other vehicle is ahead or approaching
Full beam headlights should be used on unlit roads at night when there are no other vehicles ahead or approaching. You must dip them when you see oncoming traffic or are following another vehicle.
