Is it permitted to have a car’s low beam and fog lights on at the same time?

  • Incorrect: Yes, it is always permitted.
  • Incorrect: Yes, but only if there is heavy fog.
  • Correct: No, it is never permitted.

Using low beam or daytime lights at the same time as fog lights is prohibited.” (Driving Licence Book, 19th Edition, page 158)

This is because the combination can dazzle other drivers.
