A cracked windshield is covered by auto insurance if you carry comprehensive coverage on your vehicle policy. Comprehensive insurance pays to repair or replace windshields damaged by flying rocks, road debris, severe weather, fallen trees, animal strikes, or vandalism. Standard liability-only policies do not cover windshield damage, while collision coverage only applies if the glass breaks during a vehicle rollover or multi-car accident.
Key Facts: Windshield Insurance at a Glance
- Coverage Type Required: Comprehensive coverage (Other Than Collision) is mandatory for windshield repair or replacement.
- Deductible Waiver for Repairs: Most auto insurance carriers waive the comprehensive deductible entirely for minor glass repairs under six inches long.
- Zero-Deductible States: Drivers in Florida, South Carolina, and Kentucky receive $0 deductible windshield replacements by state law if they carry comprehensive insurance.
- ADAS Recalibration Coverage: Comprehensive coverage includes the cost of recalibrating Advanced Driver Assistance System (ADAS) cameras during windshield replacement.
- Insurance Rate Impact: Single glass claims rarely raise auto insurance premiums because they fall under non-fault comprehensive coverage.
How Does Windshield Insurance Coverage Work?
Auto insurance handles glass damage through your policy’s comprehensive coverage section, which protects against physical damage caused by events outside your control. When road debris or temperature stress cracks your windshield, the insurance response depends on whether the damage requires a minor resin repair or a total windshield replacement.

Deductible Waived ($0 Out-of-Pocket) Comprehensive Deductible Applies
(Or $0 via Glass Endorsement)
Insurers classify glass claims into two separate administrative workflows based on structural safety standards:
1. Windshield Repair (Damage Under 6 Inches)
If the glass damage is smaller than a standard dollar bill and located outside the driver’s direct line of sight, technicians can inject a clear resin into the crack. Insurance companies prefer repair over replacement because a resin repair costs them between $60 and $150. Consequently, almost all insurance carriers waive your deductible for repairs, making the service completely free out of pocket for you.
2. Windshield Replacement (Damage Over 6 Inches)
If a crack exceeds six inches, penetrates both layers of glass, or impairs the vision of the driver, the windshield must be fully replaced to preserve structural integrity. For replacements, you must pay your agreed comprehensive deductible, which typically ranges from $100 to $1,000. Your insurance company pays the remaining balance directly to the auto glass installation facility.
Which Auto Insurance Types Cover Glass Damage?
Understanding which specific policy components cover glass damage prevents unexpected out-of-pocket expenses when filing a claim. Auto insurance policies separate physical damage into distinct operational categories.
| Insurance Type | Covers Road Debris Cracks? | Covers Collision Cracks? | Deductible Applies? |
|---|---|---|---|
| Comprehensive Coverage | Yes | No | Yes (Waived for repairs in most cases) |
| Collision Coverage | No | Yes | Yes (Standard collision deductible) |
| Full Glass Endorsement | Yes | Yes | No ($0 out-of-pocket for all glass) |
| Liability Only Coverage | No | No | N/A (No coverage provided) |
Comprehensive Insurance
Comprehensive coverage is the primary policy component that pays for windshield repair and replacement. It covers non-collision events including rocks kicked up by highway traffic, falling tree limbs, hail damage, extreme temperature changes, animal impacts, and vandalism.
Collision Insurance
Collision coverage only pays for windshield replacement if the glass breaks as a direct result of a motor vehicle accident, such as colliding with another car, striking a guardrail, or turning over in a rollover crash. If your windshield shatters during a car crash, the glass claim is bundled into your total collision damage claim under your collision deductible.
Full Glass Coverage Endorsement
Full glass coverage is an optional policy add-on available in select states. Purchasing this endorsement removes your deductible entirely for auto glass claims, including complete windshield replacements, side windows, and rear glass. The add-on typically adds between $10 and $40 per year to your total auto insurance premium.
Liability-Only Coverage
Property damage and bodily injury liability policies only pay for damage you cause to other vehicles and individuals. Liability insurance provides zero financial coverage for damage to your own vehicle, including broken windshields.
What State Laws Regulate Zero-Deductible Windshield Replacement?
State insurance statutes heavily influence how much you pay out of pocket for windshield repairs and replacements. Several states have enacted zero-deductible glass laws to encourage drivers to repair damaged vision-critical glass immediately without financial hesitation.

[ Mandatory $0 Deductible States ] [ Mandatory Glass Option States ]
• Florida (Comprehensive policy) • Arizona (Zero-deductible add-on)
• South Carolina (Comprehensive) • New York (Zero-deductible option)
• Kentucky (Comprehensive policy) • Massachusetts (Low glass deductible)
Mandatory Zero-Deductible States
In these states, statutory law requires auto insurance companies to replace broken windshields with zero deductible, provided the policyholder carries comprehensive insurance:
- Florida (F.S. 627.7378): Insurers must pay for windshield repair or replacement without applying a deductible if the vehicle owner maintains comprehensive coverage.
- South Carolina (S.C. Code § 38-57-210): Insurance carriers must provide comprehensive coverage for safety glass replacement with zero out-of-pocket deductible for the insured.
- Kentucky (KRS 304.20-065): Comprehensive auto insurance policies must cover full repair and replacement of windshields with no deductible applied.
Mandatory Glass Option States
Other states mandate that insurance providers offer policyholders the option to purchase a zero-deductible or low-deductible glass endorsement:
- Arizona: Insurers are required by state law to offer full glass coverage add-ons that remove deductibles for all auto glass repairs and replacements.
- New York and Massachusetts: Insurance carriers must offer specific zero-deductible auto glass options or specialized low-deductible glass tiers on comprehensive policies.
- Connecticut: State law mandates zero-deductible options for safety glass repairs and replacements under comprehensive coverage lines.
Should You File an Insurance Claim for a Cracked Windshield?
Filing an insurance claim for a cracked windshield makes financial sense in specific scenarios, but paying cash out of pocket is better in others. Evaluating the total cost of replacement against your comprehensive deductible determines the best financial route.
[ Evaluate Windshield Repair Costs ]
|
____________________________|____________________________
| |
[ Cost < Deductible ] [ Cost > Deductible ]
• Example: $350 glass / $500 deductible • Example: $1,200 ADAS glass / $250 deductible
• Recommendation: Pay Cash • Recommendation: File Claim
• Prevents claim entry on C.L.U.E. • Insurance pays balance of $950
When to File an Insurance Claim
- The total cost exceeds your deductible: If replacing your windshield costs $1,200 due to advanced camera systems and your deductible is $250 or $500, filing a claim saves you hundreds of dollars.
- You have full glass coverage or live in a zero-deductible state: When state law or policy endorsements guarantee a $0 out-of-pocket balance, file the claim immediately.
- The damage is repairable: Minor chips under six inches are repaired for $0 out-of-pocket by nearly all carriers without triggering policy deductibles.
When to Pay Cash Out of Pocket
- The replacement cost is lower than your deductible: If an independent glass shop quotes $300 to replace glass on an older vehicle and your comprehensive deductible is $500, insurance will pay $0. Filing a claim in this scenario adds an unnecessary claim record to your insurance file.
- The quote is slightly above your deductible: If replacement costs $550 and your deductible is $500, insurance pays only $50. Paying cash prevents a comprehensive claim entry on your Comprehensive Loss Underwriting Exchange (C.L.U.E.) report for a minimal payout.
What Is the Difference Between OEM and Aftermarket Glass Coverage?
When replacing a cracked windshield, insurance claims adjusters default to paying for aftermarket glass unless your policy contains specific provisions for original equipment manufacturer parts.
Original Equipment Manufacturer (OEM) Glass
OEM glass is produced by the exact manufacturer that built the factory glass original to your vehicle, such as Pilkington, Carlex, or AGC. It matches identical thickness, optical clarity, ultraviolet coatings, and camera mount positioning specifications. Insurance carriers typically cover OEM glass only under three conditions:
- Your vehicle is from the current or previous model year (less than 2 years old).
- Your policy includes a paid OEM Parts Endorsement.
- The vehicle’s ADAS safety sensors fail diagnostic tests with aftermarket glass options.
Aftermarket Auto Refinishing Glass (ARG)
Aftermarket glass is manufactured by third-party companies that acquire design templates to recreate the windshield shape. While ARG glass meets Federal Motor Vehicle Safety Standards (FMVSS), it may feature slight variances in thickness, solar tint, and camera mounting brackets. Insurance companies prefer ARG glass because it costs 30% to 60% less than OEM glass.
Why Is ADAS Recalibration Mandatory During Windshield Replacement?
Modern vehicles equipped with Advanced Driver Assistance Systems (ADAS) rely on forward-facing optical cameras mounted behind the top center of the windshield. These cameras power essential safety features including automatic emergency braking, lane departure warning, lane keeping assist, and adaptive cruise control.

[ Static Recalibration ] [ Dynamic Recalibration ]
Target boards in facility Test drive at precise speeds
When a technician removes and replaces a windshield, the optical alignment of the camera shifts by fractions of a millimeter. Uncalibrated cameras miscalculate distance targets on the road, creating severe safety risks.
Static vs. Dynamic ADAS Recalibration
- Static Recalibration: Technicians place physical target boards at precise distances and heights in front of the vehicle inside a controlled facility service bay. Vehicle computer diagnostics adjust camera pitch, roll, and yaw angles based on target recognition.
- Dynamic Recalibration: Technicians connect a handheld diagnostic tool to the vehicle’s OBD-II port and drive the vehicle on marked roads at specified speeds (typically 40–50 mph) for 15 to 30 minutes until the camera system self-calibrates.
Insurance comprehensive policies must and do cover ADAS recalibration as part of the windshield replacement claim. The combined recalibration service adds $300 to $600 to the total bill, making insurance coverage critical for modern vehicles.
How to File a Windshield Insurance Claim Step-by-Step
Filing an auto glass claim follows a streamlined process distinct from standard accident claims. Follow these steps to complete your claim efficiently:
Step 1: Document the Glass Damage
Take clear photographs of the damage from both inside and outside the car. Capture one wide shot showing the entire vehicle and windshield, followed by close-up photographs next to a ruler or a standard dollar bill to prove size dimensions.
Step 2: Review Your Insurance Coverage
Log into your insurance carrier’s mobile app or website to confirm that your policy includes comprehensive coverage. Check your policy declarations page to verify your exact comprehensive deductible amount and determine if you have a full glass coverage endorsement.
Step 3: File the Claim via Third-Party Administrator or App
Submit your claim online, through your carrier’s app, or by calling your insurer’s glass claims department. Most major insurance carriers delegate glass management to Third-Party Administrators (TPAs) such as Safelite Solutions or LYNX Services. The TPA verifies coverage and issues a claim reference number.
Step 4: Select Your Authorized Auto Glass Repair Facility
Under consumer rights laws in all 50 states, you have the legal right to choose any licensed auto glass repair shop. While TPAs may recommend their own network facilities, you can direct the claim payout to any independent certified auto glass technician.
Step 5: Schedule Service and Recalibration
Arrange for an in-shop installation or request a mobile installation unit to perform the replacement at your home or workplace. If your vehicle features safety cameras, confirm the facility has calibrated diagnostic equipment to complete the mandatory ADAS recalibration on-site.
Step 6: Inspect Workmanship and Pay Deductible
Before signing off on the work, inspect the glass for seal gaps, wind noise, or distortion. Verify that your vehicle dashboard displays no ADAS error lights. Pay your comprehensive deductible directly to the glass installation shop; the shop bills the remaining balance directly to your insurance provider.
Common Mistakes to Avoid When Filing Glass Claims
- Delaying glass repairs: Small windshield chips expand quickly when exposed to defroster heat, summer sun, or road bumps. Delaying a free resin repair turns a simple fix into a mandatory replacement requiring your deductible.
- Filing claims for bills under your deductible: Submitting an insurance claim for a $350 repair bill when holding a $500 deductible results in $0 paid by the carrier while logging an active claim flag on your C.L.U.E. insurance history.
- Ignoring ADAS recalibration requirements: Declining camera recalibration after glass replacement leaves critical emergency braking and lane assist systems uncalibrated, posing severe safety hazards.
- Attempting DIY resin repairs on long cracks: DIY glass repair kits sold at retail stores work reasonably well on minor bullseye chips but fail completely on running cracks or damage extending into the driver’s line of sight.
Frequently Asked Questions
Does filing a windshield claim increase auto insurance rates?
Filing a single windshield claim rarely increases your auto insurance rates. Insurance companies classify glass damage under comprehensive coverage as a non-fault event. However, filing multiple comprehensive claims (typically three or more within a 36-month window) can lead to policy premium surcharges or loss of your claims-free discount upon policy renewal.
Can insurance force me to use a specific auto glass shop?
No, insurance companies cannot force you to use a specific auto glass repair shop. Under state insurance regulations across the United States, you maintain the legal right to choose any licensed auto glass repair facility. Insurance providers may inform you about network shops offering direct billing, but they must honor your shop selection.
How long does windshield replacement and curing take?
A standard windshield replacement takes 1 to 2 hours to install. However, the vehicle must sit parked for an additional 1-hour minimum drive-away time while the urethane adhesive cures to structural strength. If your vehicle requires ADAS camera recalibration, add another 45 to 60 minutes to the overall service duration.
Will insurance cover a windshield cracked by extreme temperature?
Yes, insurance covers windshields cracked by severe temperature changes under comprehensive coverage. Extreme thermal expansion occurs when cold windshield glass is hit with hot defroster air or when hot summer glass is washed with freezing water. Because temperature stress is a non-collision physical damage event, comprehensive coverage applies.
Is rear glass or side window damage covered the same as a windshield?
Yes, side windows and rear windshields are covered under your auto insurance comprehensive policy just like the front windshield. However, side and rear windows are constructed from tempered glass that shatters into small dull pieces upon impact rather than laminated glass, meaning they always require full replacement rather than resin repair.
