BDifficulty 3/5

Within a built-up area, with no danger justifying the horn, how may you warn the driver ahead that you intend to overtake?

Correct answer

With light warnings without dazzling.

Use brief flashes of dipped or main-beam headlights, or alternate them, without dazzling, under Article 109.3. Horn use solely to announce overtaking is allowed outside built-up areas, not in this case. This does not prevent appropriate horn use to avoid a possible collision. If overtaking involves lateral movement, also signal that movement with the appropriate indicator; indicators are not the only permitted light warning.
