Car Rear Windshield Lines: The Hidden Safety Feature 50% Don't Know

• The thin, horizontal lines on a car's rear windshield are called defogger grids or demister lines.
• These lines are electric conductors that heat up to remove fog, mist, and ice from the rear window.
• Activating the rear defogger button sends electricity through these lines, causing them to heat and clear the windshield.
• They significantly improve rear visibility, enhancing driving safety, preventing accidents, and are often a legal requirement.

Why It Matters: Rear windshield lines are defoggers, vital for clear visibility and accident prevention.
