Winter Tyres in Europe

Update: 01 October 2020

| OPONEO.IE

If you are planning to drive around Europe in the winter season, you should know the legal regulations concerning the car winter equipment. This varies from country to country so it pays to check what is mandatory in your destination.

Winter tyres or snow chains are not required everywhere but it doesn’t mean you will never have to fit them. Their use can be dictated by road conditions or local signs, which you are likely to see when driving through mountainous regions in France, Austria, Sweden, Switzerland or Norway.

Failing to use winter tyres or other elements required for safe driving in winter poses a serious risk of getting involved in a car accident. And if you have an accident where winter equipment should have been used, it is automatically considered to be your fault so you will not be covered by your insurer.
