What must you note when driving in other European countries in winter?

Your answer is correct because in many European countries during winter, there are specific requirements to ensure road safety in snowy or icy conditions. First, the minimum tread depth of tyres ensures that tyres have enough grip on slippery surfaces. Second, the obligation to fit winter tyres means that you must use tyres designed for cold weather, which perform better in ice and snow. Third, the obligation to carry snow chains means that in some areas, you must have chains available and be ready to fit them if conditions demand. Knowing these rules helps prevent accidents and potential fines when driving abroad in winter. Always check the specific regulations of the country you plan to visit.
