Your closed trailer is 6.50 metres long and 1.90 metres wide (permitted maximum mass 900 kg). Which extra light is now required on account of its dimensions?
No extra light — marker lights are not needed on a passenger trailer
Marker lights — the trailer is longer than 6 metres
Position lights — the trailer is wider than 1.60 metres
Explanation
False — trap: marker lights never needed. Required **>6 m long or >2.10 m wide**; 6.50 m qualifies (Book p.232).
