What must you be aware of when operating your motor vehicle in wintry conditions?

Your answer is fully correct. In wintry conditions, German traffic rules require that your vehicle is equipped with winter tyres to ensure proper grip on snow and ice. Additionally, any entry or exit steps must be cleared of snow and ice to prevent slipping and ensure safety when getting in or out. Lastly, the windscreen must have enough antifreeze in its washer fluid to keep the view clear and avoid frozen wipers, which is essential for safe driving. All these measures help maintain safety and vehicle functionality in winter weather.
