Between 1 November and 15 April, drivers of trucks with a permissible maximum weight exceeding 3.5 t and omnibus drivers as well as drivers of related vehicles are required to carry suitable snow chains for at least two driving wheels on-board.
Snow chains may only be used if necessary and only if they are mounted in such a way that they do not damage the road surface (only in case the road is covered by a complete or scarcely broken snow cover or sheet of ice).
Vehicles exempt from this regulation are:
- Vehicles on which it is impossible to mount snow chains for design reasons
- Vehicles that can only be used on snow-free roads due to their design
- Vehicles belonging to Class M2 and M3 (omnibuses) used for public transportation
- Vehicles brought to the producer of superstructural parts for utility vehicles or to the customer, as far as the drive is on roads clear of snow.
