In the evening rush hour, stuck in a jam, you think about your 1.80 m wide trailer with a permitted maximum mass of 600 kg. Which conditional light is mandatory here?
Marker lights — they belong on every wider trailer
A reversing light — mandatory as soon as the trailer is wider than 1.60 m
Front position lights — the trailer is wider than 1.60 m
Explanation
Wrong — trap: threshold on the wrong light. **Position light: >1.60 m wide · reversing light: >750 kg** (Book p.232).
