Mandatory use of winter tyres

Winter tyres are mandatory for heavy goods vehicles beyond 3.5 tons from 15 November to 31 March. Heavy goods vehicles beyond 3,5 tons are also required to be equipped with tyres with a tread depth of at least 5 mm and a sufficient number of snow chains.

Studded tyres may only be used between 1 November and the first Monday after Easter Monday. In the counties of Nordland, Troms and Finnmark, studded tyres may be used from 16 October up to and including 30 April. There are no such date restrictions when it comes to non-studded winter tyres.

The vehicle must have winter tyres (studded or non-studded), chains or similar also outside of the periods mentioned above if this is necessary in order to ensure sufficient road grip. If snow or ice can be expected on the roads, the vehicle must carry chains regardless of the time of year.
