TL;DR
- In Minnesota, auto insurers are required by law (Minn. Stat. § 65B.49) to offer comprehensive glass coverage.
- Windshield repair is often covered with no deductible; replacement falls under comprehensive coverage, and your deductible applies unless you have zero-deductible glass coverage.
- You have the legal right to choose your own auto glass repair company, regardless of your insurer's referral.
- Auto Glass Express is approved by all major insurers and can file your claim on your behalf.
What Does Car Insurance Actually Cover for a Cracked Windshield?
In most cases, windshield damage is covered under the comprehensive portion of your auto insurance policy, not collision. Whether your repair or replacement costs you anything out-of-pocket depends on the size of the damage, your deductible, and your specific policy.
Comprehensive coverage pays for damage caused by events outside your control: falling objects, road debris, weather, and similar hazards. A rock kicked up by a truck ahead of you is a classic example. If you have comprehensive coverage, your windshield damage qualifies.
The key distinction:
- Windshield repair (small chips, cracks under 6 inches not in the driver's line of sight): Many insurers cover this with no deductible, because repair is significantly cheaper than replacement and preserves the original factory seal.
- Windshield replacement (larger cracks, damage in the driver's sightline, or damage extending from an edge): Covered under comprehensive, but your standard deductible applies — unless you carry a zero-deductible or full glass endorsement.
Minnesota Glass Coverage Law: What Drivers Need to Know
Minnesota law requires auto insurers to make comprehensive glass coverage available to every policyholder. Under Minnesota Statute § 65B.49, insurers must offer this coverage, but whether you have it depends on whether you purchased it.
If you carry comprehensive coverage in Minnesota, review your declarations page for a "full glass" or "zero deductible glass" endorsement. Many Minnesota drivers have this coverage and don't realize it.
Key facts for Minnesota drivers:
- Minnesota is a no-fault auto insurance state, but glass claims run through comprehensive, not no-fault (PIP) coverage.
- Filing a glass claim in Minnesota generally does not affect your premium. Glass claims are considered "not-at-fault" events, and most insurers do not surcharge for them. Confirm this with your specific insurer before filing if you are concerned.
- You are not required to use the repair shop your insurer recommends. Minnesota law, consistent with most states, gives you the right to choose your own qualified glass company.
Repair vs. Replacement: How to Know Which One You Need
The deciding factors are crack length, location on the windshield, and depth of damage. Repair preserves the original glass and seal; replacement is required when the structural integrity of the windshield is compromised.
When Repair Is Usually Sufficient
A chip or crack is typically repairable when it meets all of these conditions:
- Smaller than a quarter in diameter (chips) or shorter than 6 inches (cracks)
- Not directly in the driver's primary line of sight (the "acute area" in front of the steering wheel)
- Does not extend to the edge of the windshield
- Has not been contaminated by dirt or moisture
Common repairable damage types include bullseye, star, half-moon, and combination breaks.
When Replacement Is Required
Replacement is necessary when:
- The crack extends from any edge of the windshield (edge cracks spread rapidly and cannot be effectively stabilized)
- The damage is directly in front of the driver
- The chip or crack is too large for resin injection to restore optical clarity and structural strength
- The glass has multiple impact points that compromise the laminate
ADAS Recalibration After Windshield Replacement: A Critical Step Many Drivers Miss
If your vehicle has a camera, rain sensor, or lane-departure system mounted to or near the windshield, replacement requires professional recalibration of those systems. Skipping recalibration can disable safety features or cause them to malfunction.
Advanced Driver Assistance Systems (ADAS) — including forward collision warning, automatic emergency braking, lane-keeping assist, and adaptive cruise control — depend on cameras and sensors that are precisely aimed through the windshield. When the windshield is replaced, even minor shifts in glass thickness or positioning can throw off sensor calibration.
What drivers should know:
- Recalibration is a separate service from windshield replacement and typically requires specialized equipment.
- Many insurance policies that cover windshield replacement also cover required ADAS recalibration, confirm with your insurer when filing your claim.
- Auto Glass Express performs ADAS recalibration and will advise you at the time of service whether your vehicle requires it.
How the Insurance Claim Process Works for Windshield Damage
To have your windshield repair or replacement covered, you must file a comprehensive insurance claim before the work is done. You choose the shop; the insurer pays them directly or reimburses you, minus any applicable deductible.
The standard process:
- Assess the damage — determine if it's a repair or replacement (your glass shop can help).
- Contact your insurer — file a claim under your comprehensive coverage. Note your claim number.
- Choose your shop — you are not required to use your insurer's referral network.
- Schedule service — the shop will confirm coverage with your insurer directly.
- Pay any deductible — this is paid directly to the shop at the time of service.
- Drive safely — wait the recommended cure time before driving if a replacement was performed.
