Lastly, the windscreen washer system is essential for visibility, and if it freezes, it can hinder driving safety. German traffic rules emphasize vehicle readiness and safety, making it crucial to ensure that all of these components are checked and maintained to prevent hazards associated with winter driving conditions.
