Question

DentroTest · Accepted Answer

The General Vehicle Regulations (Annex IX, Table 1) set specific axle mass limits for buses. As a general rule, the maximum mass on a single driving axle is 12 tonnes (since 23 October 2025; before, 11.5). For Class II (interurban) and Class III (long-distance) buses, an extended limit of 12.6 tonnes is authorized. The 13 tonnes is the limit for the driving axle of urban buses (Class I). The 16 tonnes does not correspond to any single axle, whose maximum reaches 13 tonnes.
