No, you should not drive with broken car glass. It is illegal in all 50 states to operate a vehicle with a compromised windshield or window that obstructs your view. Beyond the legal risk, it poses immediate safety hazards. A broken windshield loses its structural integrity, meaning it may not support the roof in a rollover accident or properly deploy the passenger-side airbag. Driving with a broken side window exposes you to the elements, potential theft, and projectiles from the road.
The primary concern is the windshield. Modern windshields are made of laminated safety glass, which consists of two layers of glass with a plastic interlayer. This design prevents the glass from shattering into large, sharp pieces. However, a crack can quickly spread due to temperature changes, road vibrations, or wind pressure, leading to a complete failure of visibility.
Here’s a quick guide based on the damage type:
| Type of Damage | Is it Safe to Drive? | Immediate Action |
|---|---|---|
| Small Windshield Chip (< 6 inches) | Possibly, but with caution | Drive directly to a repair shop. Avoid sudden temperature changes (like blasting the A/C). |
| Long Windshield Crack | No, it's unsafe | The vehicle should be towed to a repair facility. The crack can spread rapidly, obscuring vision. |
| Shattered Side/Rear Window | Not recommended | The car is insecure from weather and theft. Drive only if absolutely necessary and at low speeds to a service center. |
| Broken Sunroof | No | Risk of further glass falling and total structural failure. Do not drive. |
Your best course of action is to get the glass repaired or replaced immediately. Comprehensive insurance coverage often covers glass repair with little or no deductible. Driving with broken glass is a risk to your safety, your passengers' safety, and your wallet from potential fines.

I drove with a cracked windshield for a week because I was busy. Big mistake. The crack grew from a tiny star to a line across my entire view almost overnight after a hot day. It was incredibly distracting, with the light refracting through the crack. I got it fixed for under my insurance deductible—took the guy less than an hour in my office parking lot. Just get it handled; it’s not worth the stress or the ticket.

As a parent, my first thought is safety. A broken window, especially the windshield, compromises the entire vehicle's safety cage. In an accident, it might not hold. It also lets in noise, dust, and debris, which isn't healthy for anyone inside, least of all kids. The risk of the glass giving way is just too high. I wouldn't drive my family in that car until it's professionally fixed. It’s a non-negotiable priority.

Legally, you're asking for trouble. Most states have strict laws about driver visibility. A cracked windshield that obstructs your view is a clear violation and can get you pulled over and ticketed. Furthermore, if you were in an accident, even if it wasn't your fault, the other party's insurance could argue your compromised vehicle contributed to the incident. It creates an unnecessary liability. Protect yourself and get it repaired properly.

If it's a small chip and you must drive to the shop, here's a temporary fix. Clean the area thoroughly and apply a clear, strong tape specifically designed for glass repair (found at auto parts stores) over the chip. This can help prevent dirt and moisture from getting in and may slow the cracking. But this is a get-you-to-the-shop solution, not a repair. For a shattered window, you can carefully seal it with a plastic bag and duct tape from the outside to keep rain out, but the car is not secure. Drive slowly and directly to the service center.
