How Long Can I Drive With a Cracked Windshield?


I don’t have a crack in my windshield.  But what if I got one?  How long can I lazily idle along before I absolutely need to take it in for a replacement? I did a little research on the safety issues of windshield cracks, and this is what I found.

Glass is unpredictable.  A cracked windshield can either last 10 years or an hour after being cracked, depending on the depth and length of the crack itself.  The windshield will not cave in unless you get in an accident, which is comforting.  What is not comforting, however, is what may happen to the airbag during that same accident.  An airbag uses the windshield as a backstop, allowing it to be pushed forward toward the passenger.  However, if the windshield is cracked, the airbag has a greater chance of breaking through, going straight up instead of toward the passenger.  This eliminates the airbag and windshield cushion, sending a passenger flying out of the car.

Statistics show that for most cars, 60 percent of roof support comes from the windshield if the car rolls over.  If the windshield is cracked, a lot of that integrity will be gone.  A rollover situation will always result in a broken windshield, but the interior is safer when it is completely intact beforehand.

Also, a crack may not break a windshield, but it may serve as a distraction or impairment to the driver.  What may seem harmless can turn dangerous if not properly addressed.

If you have a rock chip or a crack in the windshield, Diamond Glass can repair or replace your windshield so you can be safe on the road once again.
