What Are the Lines on My Rear Windshield For?

You’ve most likely noticed the lines on the rear windshield of a vehicle, even if you’ve never driven before, and have wondered what they’re for. Sure, they’re great for helping you back up along curbs and parallel park, but what’s their real job?

How is a Rear Windshield Made?

Contrary to popular belief, the rear windshield of a car is actually made from tempered glass, which is the same as your side windows. Strengthened by a thermal and/or chemical treatment, it can withstand blunt force. If for some reason it does break, it will break into tiny chunks instead of large shards, making it safer for those inside and outside of the vehicle.

What are the Lines for?

The lines on your back windshield are more beneficial than just a way to parallel park! They’re actually on their to help defrost your rear windshield. Small electrical currents run along the lines to keep your windshield clear and clean to make driving easier.

Because of these lines, replacing your rear windshield is a little different than replacing your front windshield. Luckily for you, our team at AllStar Windshield Centers can help. Contact us today at 1-800-900-1505 to schedule your rear windshield replacement.
