Neither the Road Traffic Licensing Regulations (StVZO) nor the Road Traffic Regulations (StVO) contain a definition of heavy goods vehicles. However, large and/or heavy goods vehicles are generally understood to be vehicles and vehicle combinations whose dimensions, axle loads or total masses exceed the limits permitted under Sections 32 and 34 StVZO or which do not comply with the cornering behaviour (Section 32d StVZO). The vehicles or vehicle combinations require a special vehicle authorisation in accordance with Section 70 (1) No. 1 or 2 StVZO and a permit in accordance with Section 29 (3) Sentence 1 StVO.
