Just before the Moerdijk bridge, in the early morning mist, you are driving a car of 2,800 kg permitted maximum mass with a 900 kg trailer (combination 3,700 kg). Which licence do you need at minimum?
Plain B suffices, because the trailer is lighter than 3,500 kg
BE is mandatory, B+code 96 is not allowed here
C1E, because the combination is above 3,500 kg
B + code 96 (or BE)
Explanation
False — trap: skipped middle step. At 3,700 kg combination B+code 96 already suffices; BE only becomes mandatory above 4,250 kg (Book p.233).
