Driving in fog in Ireland
Fog drastically reduces visibility and is a common theory-test scenario. Knowing when to use fog lights and how to adjust your driving is essential.
Key facts to remember
- ◆ Use dipped headlights in fog -- never full beam, which reflects back and dazzles you.
- ◆ Use front and rear fog lights only when visibility is seriously reduced (below about 100 m).
- ◆ Switch fog lights off when visibility improves, as they can dazzle other drivers.
- ◆ Slow down so you can stop within the distance you can see to be clear.
- ◆ Increase your following distance and avoid hanging on to the tail-lights ahead.
