When ice builds up on your windshield wipers while driving, stopping safely to address the issue is the most prudent course of action. Continued driving with obstructed wipers can significantly impair your vision, creating a dangerous situation. Stopping allows you to assess and remove the ice build-up effectively, ensuring that your wipers can function properly and your visibility is restored. While using the windshield washer fluid may seem like a quick fix, it may not be effective in this situation since washer fluid generally does not work well on ice. Additionally, relying solely on the defroster might not be sufficient to clear the ice around the wipers, and it could take time to warm up enough to be effective. Safety is paramount, and addressing the problem directly by stopping will help ensure you can drive safely once the ice has been removed.
