It is not recommended that you ever drive your vehicle if there is a crack that is in your view while driving. Even if the damage is repairable (minor rock chip), if the damage is in the driver’s direct line of view, insurance companies require replacement. If the crack is on the passenger’s side of the windshield, we strongly recommend replacing the windshield as soon as possible due to the safety concerns including a proper deploy of the airbags and roof retention. If the crack is on the driver’s side of the windshield, you will need to determine whether or not the crack effects your driving negatively in any way (blind spots, catches your eye, annoying, etc). If it does, then I would recommend replacing it.
I have a crack in my windshield in NJ is it safe to drive?
Glass is unpredictable, and does not follow any set rules. One rock chip may not spread for 10 years, while another rock chip may spread across your windshield 30 minutes later. Don’t let this be an immediate worry though because your windshield is designed so that it does not shatter or cave in on you randomly. The only reason that your windshield should ever cave in or completely shatter is upon extreme impact (a brick or very large rock) or during a wreck.
