It is drizzling and the digital speed signs on the A2 show 100. Your car has a permitted maximum mass of 2,800 kg, your trailer 900 kg — combination therefore 3,700 kg. May you drive this on a plain B licence alone?
Yes — the trailer is lighter than 3,500 kg, so a plain B always suffices
No — the trailer is heavier than 750 kg and the combination (3,700 kg) is above 3,500 kg; you need B+code 96 or BE
Explanation
Wrong — trap: ignoring one number. **≤750: B · 750-4,250 combi: B+96/BE · >4,250: BE** (Book p.233).
