Driving in the dark increases risk due to reduced visibility, glare and limited contrast. Use correct lights, adapt speed and expand margins.
Core principles
- Use low beam by default; switch to high beam when no one is dazzled
- Reduce speed; stopping distance must fit your visible range
- Keep longer following distances and scan more actively
- Clean windows, mirrors and lights for maximum clarity
Light use
See Use of lights and signals. Always dip for oncoming and when following closely. Use fog lights only in fog, snow or heavy rain.
