BDifficulty 2/5

Must traffic officers and roadworks personnel directing vehicle passage use conspicuously coloured clothing and retroreflective elements both by day and by night?

Correct answer

Yes, both day and night.

Yes. Article 141 requires recognition by day and by night and conspicuously coloured clothing and retroreflective devices or elements allowing them to be distinguished from at least 150 m. The question concerns those directing traffic or vehicle passage, not every activity of every police officer or worker. Equipment must meet that purpose; it is not a visibility guarantee in every circumstance.
