192. Snow chains
Snow chains are traction devices fitted around vehicle tyres to improve grip on roads covered with snow or ice. They are especially useful on steep or mountainous roads where ordinary tyres may not provide sufficient traction.
Snow chains should be fitted according to the vehicle and chain manufacturer's instructions, normally on the driven wheels. They should be removed when they are no longer needed because driving with chains on clear roads can damage the tyres, chains and road surface.

Are snow chains compulsory everywhere in winter?
No. Requirements vary between countries and roads. Some countries require chains to be carried during certain periods or fitted when indicated by traffic signs or winter conditions, while others impose no general requirement.
