Arizona traffic law does not ban driving with any windshield crack. Instead, enforcement generally focuses on whether damage:
- Obstructs the driver’s clear view of the road
- Interferes with safe vehicle operation
- Creates a safety concern for the driver or others
Cracks that are small, away from the driver’s line of sight, and not spreading are less likely to be an issue.
Cracks that impair visibility or compromise the windshield’s strength are more likely to draw attention.

While every situation is different, drivers should be cautious if a crack:
- Runs across the driver’s line of sight
- Has begun spreading or branching
- Reaches the edge of the windshield
- Causes glare or distortion in sunlight
- Weakens the windshield’s structure
Windshields play a role in airbag deployment and overall vehicle safety, which is why visibility and structural integrity matter.
Arizona’s extreme heat puts extra stress on auto glass.
During the day, windshield glass expands in high temperatures. At night, it cools and contracts. This repeated expansion and contraction can cause even small cracks to grow quickly — sometimes overnight.
Because of this, cracks that seem minor at first can worsen faster in Arizona than in cooler climates.

In Arizona, tickets related to windshield damage typically involve visibility or safety concerns, not the mere presence of a crack.

Many cracked windshields are covered under comprehensive auto insurance, but deductibles and coverage vary by policy.
Some drivers choose to use insurance, while others prefer cash options to avoid deductibles or claims. In many cases you will be eligible for a cash rebate if you choose to replace your windshield!
