CDifficulty 3/5

For goods vehicles other than tractor units, which two thresholds does the Ministry of Transport Road Transport Observatory (2026) use to classify them as heavy?

Correct answer

MAM over 6 t and payload capacity over 3.5 t.

MAM over 6 tonnes together with payload capacity over 3.5 tonnes. This is the specified Observatory classification, rather than the general 3,500 kg threshold used by other traffic rules. Exceeding just one limit is insufficient. Tractor units are excluded from this case.
