You're following other vehicles in fog. You have your headlights on dipped beam. What else can you do to reduce the chances of being in a collision?
- A Keep close to the vehicle in front
- B Use main beam instead of dipped headlights
- C Keep up with the faster vehicles
- D Keep a safe distance from the vehicle in front
Why this is the answer
When it’s foggy, use your headlights on dipped beam. This will help you see and be seen by other road users. If visibility is seriously reduced, consider using front and rear fog lights if you have them. Keep to a sensible speed and do not follow the vehicle in front too closely. If the road is wet and slippery, you’ll need to allow twice the normal stopping distance.
Why the other answers don't fit
- A
- Keep close to the vehicle in front — Using someone else's tail lights as a guide is how cars end up piling into one another in fog.
- B
- Use main beam instead of dipped headlights — Main beam reflects off the fog and leaves you seeing less, not more.
- C
- Keep up with the faster vehicles — Their speed is not evidence that the speed is safe.
