  2. No, if your lights are on.
  3. Distance has no effect on Detention in fog.

Correct answer: Yes, to have more space to react if the vehicle ahead brakes.

Fog reduces visibility, so you should leave more distance between your vehicle and the one ahead. This gives you more room to react and stop if it brakes.
