Snow chain law: November 1st - April 15th
Snow chain law depends on the country. Please get information up-to-date because laws might change.
In Austria there are different laws concerning the use of snow chains.
The driver of a motor vehicle is basically obligated to use tyres fitting to the road and weather conditions which avoid any danger and correspond to the law.
Cars and trucks up to 3.5 t permissible maximum weight (class M1 and N1)
Between November 1st and April 15th the driver of a vehicle class M1 or N1 is only allowed to drive, if he uses exclusively winter tyres for winter road conditions, especially a snowy road surface, watery mud or ice. Who nevertheless uses summer tyres and drives on a road with a connected or almost constant snow- or ice-surface, has to have snow chains on at least two driving wheels. With winter road conditions you are not allowed to drive without snow chains.
This means you are not allowed to drive with summer tyres during light snow fall, mud or sporadic snowy road conditions (e.g. the track is free of snow, but snow lies next to it) - neither with snow chains!
Attention! Snow chain by law!!!
Snow chain by law (also for four-wheel.drive) is indicated with a round blue sign with the snow chain symbol in all wintersport countries.
From this point all vehicles, driving on the road, have to have at least two snow chains on two driving wheels.
With an additional sign this rule can be extended and driving with winter- and accordingly year-round tyres is allowed. Continuing on these roads with summer tyres is not allowed in any case.
Vehicles with four-wheel drive have to have snow chains at least on two tyres of a driving axle.
Most countries do not allow speed limits higher than 50 km/h with snow chains.
