Which windshield feature is crucial in winter conditions?

The crucial feature for winter conditions is the proper functioning and antifreeze in your windshield. During cold weather, it’s essential that the windshield remains clear to ensure good visibility. If the windshield wipers, washer fluid system, or other components aren't in working order, they can become ineffective in clearing away snow, ice, or slush, leading to potentially dangerous driving conditions.

Antifreeze for the windshield wiper fluid is especially vital; it prevents the fluid from freezing in the reservoir and ensures that when you need to use the windshield washer system to clear away winter elements, it will actually work. Ensuring all components involved in maintaining visibility are functioning optimally is key to safe driving during winter weather.

While heated wipers and a heated defroster can also help, they are enhancements rather than the primary necessity. Tinting for sunlight is not a winter-specific feature and does not have relevance in maintaining visibility in snowy or icy conditions.
