Wherever you drive, you are responsible for equipping and controlling your vehicle correctly. You may be liable to a fine if you impede the normal flow of traffic or cause an accident as a consequence of not adapting your vehicle (tyres/snow chains) to suit weather and road conditions.
Winter conditions in many resorts will be more severe than anything encountered here. You should only consider driving in extreme winter conditions if you're confident and your vehicle suitably equipped.
The table shows winter tyre/snow chain requirements as they apply to a visitor rather than to a resident.
Some countries require residents to use winter tyres but then permit visitors to drive on 'summer' tyres – fitted with chains when conditions or local signs dictate. If you are planning to drive for a considerable distance in mainland Europe during the winter months we strongly recommend fitting winter tyres.
