Division 12, Chapter 4
It's illegal to drive in California with a windshield that blocks your view.
That's the short version of Vehicle Code 26710. Here's exactly what the law says, what happens if an officer cites you, and how fast you can get it fixed.

What the law actually says
Section 26710 sits in the part of the Vehicle Code covering windshields and mirrors. In plain terms, it's illegal to drive if your windshield or rear window is damaged badly enough to block your view — front or back. Here's the relevant text:
There's no size threshold written into the statute — the question an officer is actually asking is whether the damage impairs your view, not how many inches the crack measures.
What usually counts as a violation
Officers and repair shops generally treat these as clear-cut cases:
- A crack or chip sitting directly in the driver's line of sight
- A "star" or "spiderweb" crack that spreads across a wide area
- Any damage large enough to catch light and cause glare at night
- Objects, stickers, or materials on the glass that block your view (a separate but related rule under the same chapter of the code)
A small chip off to the side, outside your direct line of sight, is a judgment call — but it rarely stays small, and most repair shops can fix a chip in under 30 minutes for a fraction of what a full replacement costs.
What happens if you're cited
The officer can also issue you a notice to appear and require you (or the vehicle's owner) to show satisfactory proof in court that the repair was made. In practice, that usually just means keeping your repair receipt in case it's ever asked for — but skipping the fix entirely can lead to further citations or, in repeat cases, an arrest.
Common questions
Is a small chip actually worth fixing?
Almost always, yes. A chip that's currently outside your line of sight can spread into a crack the next time the temperature swings or you hit a pothole — at which point it's both a safety issue and a 26710 violation. Repairing a chip early is usually a fraction of the cost of a full replacement later.
Does my insurance cover this?
Many comprehensive auto policies in California cover windshield repair with a low or waived deductible, since insurers would rather pay for a cheap repair than a full replacement claim later. Your provider can usually tell you in a two-minute call.
Repair or full replacement — how do I know which I need?
As a rule of thumb: a chip smaller than a quarter, or a crack shorter than about 3 inches and away from the edge of the glass, can usually be repaired. Anything longer, closer to the edge, or directly in your sightline typically needs a full replacement.
What if the damage is on my rear window, not the windshield?
Section 26710 explicitly covers the rear window too — the same 48-hour requirement and the same "does it impair your vision" standard apply.
