For drivers whose vehicles do not include this function, preparation still makes a noticeable difference. Windshield covers can prevent frost buildup overnight, while keeping the interior dry helps limit fogging. Cleaning the inside of the windshield regularly and reducing excess moisture—such as wet floor mats or snow-covered clothing—can also improve morning visibility during colder months.
Important information:
Many vehicles already have a windshield defrost feature that uses warm air and moisture control to clear frost and fog quickly. The defrost button is typically marked with a curved glass symbol. Using this feature reduces the need for scraping, protects the windshield, improves visibility, and helps make winter driving safer and less stressful from the moment the car is started.
