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.

The Importance of Advanced Drivers Assistance Systems (ADAS)

Advanced Drivers Assistance System are safety technology installed in your vehicle that work together to help reduce auto collisions and injuries.

How Do Advanced Drivers Assistance Systems Affect the Windshield?

With ADAS, front-facing cameras are typically installed on the upper, inner surface of the windshield or attached to the headliner and they must be recalibrated after a windshield replacement.  If these cameras are not calibrated properly after a windshield repair or replacement the ADAS will not work properly and will give inaccurate information to the driver.

What is ADAS Recalibraton?

After the windshield has been replaced, the ADAS cameras are reinstalled in/on the vehicle and in order for them to work properly, they need to be recalibrated.

  • Static Recalibration – A target image is mounted in front of the vehicle to assist with the recalibration process and takes roughly 45-minutes
  • Dynamic Recalibration – The vehicle is driven on a road at a specific speed to recalibrate the systems and typically takes 30-minutes to one hour.

Depending on the make and model of your vehicle, both types of recalibration might be necessary.

Upcoming Windshield Changes Look to Change the Way You Drive

Since its invention in the early 1900s, the windshield has quietly gone through an evolution from a regular piece of glass to a shatterproof work of scientific art. Its changes have not been flashy or even detectable to the untrained eye. All that is set to change over the next several years, as inventors across the globe are work on developing new windshield technology, from heads-up displays for pertinent information to water-repellant glass.

Heads-up displays are not new technology, having been introduced on fighter jets in the height of World War II. Over the last five years, they have begun to be incorporated into automobiles to curb using the phone or looking away from the road, showing information like speed and fuel readings right on the windshield instead of the lower dashboard. Bluetooth capability is being incorporated to allow drivers to make hands-free calls and text messages via the HUD, and future capabilities expected to be included range from local points of interest to advertisements. This technology is expected to grow into the mainstream over the next several years and be worth over 1 billion dollars.

Another expected feature of HUD is windshield wiper control, unless one of the car companies working to make wipers obsolete achieve their goal. Fioravanti, McLaren and Mercedes-Benz are among the manufacturers looking to do without wipers in upcoming models of their cars. Fioravanti revealed the Hidra in 2008, which used a four-layer, self-cleaning glass treatment process to repel water and dirt. Hidra was followed by McLaren, who announced a concept utilizing military technology in 2014. While Hidra relied on a constant electric current to keep water off the car, McLaren’s vision involves a ultrasonic sound barrier used on low-flying military aircraft. While neither option is scheduled to hit the roads in the foreseeable future, they are sure to change the windshield care game.
