BDifficulty 2/5

During daylight outside built-up areas, in dense fog or heavy rain reducing visibility, may main beam be used if it does not dazzle other users?

Correct answer

Yes.

Yes, Article 106 allows front fog lights, dipped beam or main beam in those conditions, subject to other rules, especially avoiding dazzle. Permission does not mean recommendation: fog reflection often worsens vision, and dipped beam with front fog lights where appropriate is preferable. The 6.50 m width concerns another front-fog use case, not this main-beam permission. Do not generalise to urban roads or situations causing dazzle.
