Without weather or environmental conditions significantly reducing visibility, when does article 106 permit front fog lamps on a narrow section with many bends?

Correct answer

A carriageway of 6.50 m or less with signed closely spaced bends.

When the carriageway is 6.50 m wide or less and the section is signed as a succession of closely spaced bends. A single dangerous bend or one-way traffic is insufficient. Article 106 also permits these lamps in its specified reduced-visibility conditions. Follow the operating conditions and avoid dazzling.
