CDifficulty 3/5

Under current Annex IX, compare an articulated vehicle with a two-axle motor vehicle and three-axle semi-trailer with a road train with a two-axle motor vehicle and three-axle full trailer. Without alternative-fuel, zero-emission, timber or special-authorisation increases, what are their respective general MAM limits?

Correct answer

44 tonnes and 42 tonnes, respectively.

44 tonnes for the specified articulated vehicle and 42 tonnes for that road train. Having five axles does not give both the same limit: the table distinguishes motor-vehicle and trailer or semi-trailer configurations. For example, road trains with a three-axle motor vehicle and a two- or three-axle trailer are listed at 44 tonnes. Former universal answers of 40 or 38 tonnes do not match these current configurations. Axle limits, technically permissible masses and the authorised MAM in the documents must also be observed.
