Many states in America have their own set of laws in regard to broken auto glasses. No matter where you are located, you should have knowledge about how the laws in your state of residence apply to driving with a cracked windshield.
Even if your state doesn’t have specific laws concerning cracks in the auto glass, you should avoid driving in such a scenario for your own safety.
In those states where there are laws on “impaired driver’s vision”, you should avoid driving with a broken windshield in particular. Even if the related laws don’t clarify what exactly “impaired driver’s vision” includes, you should expect to get a ticket if an officer asks you to pull over.
There are other concerns as well. For example, you can’t take a driving test with a cracked or broken windshield in Texas. During a driving test, the windshield, as well as all the auto glasses of your vehicle, should be clean and free from any kind of cracks, chips, and dents.
