Is driving with a cracked windshield dangerous?

Yes. Driving with a chipped or cracked windshield is dangerous. It’s cracked windshieldnot just a windscreen to keep the wind out of your face. It’s actually a structural member of the vehicle. Once it develops a crack or chip, it loses most of its structural integrity.

Windshield provides structural support
