About Fog: why your normal driving habits no longer apply: which statement is WRONG?
- In dense fog the normal two-second following distance is still sufficient.
- Fog lights help others see you, but change nothing about your own reduced sight; you adjust your driving (speed, distance) regardless, once visibility is severely limited.
- You follow the right-hand lane as much as possible, so that in an emergency you can use the hard shoulder as a direct escape route.
- Referably do not overtake in dense fog, not even on a motorway.

Correct answer: In dense fog the normal two-second following distance is still sufficient.
In very dense fog (visibility under 50 metres) three seconds, not two, applies
Why learners get this wrong: As long as your fog lights are on, you don't need to reduce your speed further — others will see you anyway.
