A rigid four-axle lorry with conventional diesel propulsion is not carrying roundwood or operating under a special authorisation. None of its drive axles has dual tyres. Subject to technical and axle limits, which general MAM limit in Spain’s vehicle regulation table applies?

Correct answer

31 tonnes.

31 tonnes, for other rigid four-axle vehicles. This case does not meet the 32-tonne row’s conditions: a rigid four-axle vehicle with two steering axles and the specified dual-tyre and air-or-equivalent-suspension conditions, or dual tyres on each drive axle with each axle’s maximum mass no greater than 9.5 tonnes. Air suspension alone does not give every four-axle lorry a 32-tonne limit. The rules also contain special cases, including specified roundwood transport, which are excluded here. Technical mass, axle limits and other applicable restrictions must be observed even if lower.
