Under the Kentucky windshield replacement law, if your auto policy includes comprehensive coverage, your insurer must pay to repair or replace damaged vehicle glass with no deductible. That rule comes from KRS 304.20-060, and it makes Kentucky one of the more driver-friendly states for glass claims. Separately, state law requires every car on public roads to have a windshield meeting federal safety-glazing standards, and violations run from $20 to $250 depending on the offense.
The Zero-Deductible Rule for Glass Claims
KRS 304.20-060 requires any motor vehicle insurance policy providing comprehensive or other-than-collision coverage to pay for repair or replacement of damaged vehicle glass “without regard to any deductible or minimum amount.”1Kentucky Legislative Research Commission. KRS 304.20-060 – Coverage for Motor Vehicle Glass If you carry comprehensive coverage and file a glass-only claim, your insurer cannot charge you a deductible. That applies to a small chip repair and to a full windshield replacement alike.
The important qualifier is “glass only.” If the damage extends to other parts of the vehicle, the standard comprehensive deductible can still apply to the rest of the claim. But for a straightforward cracked or broken windshield, you pay nothing.
What Coverage You Need
Kentucky’s mandatory auto insurance requirements do not cover your own windshield. The state’s no-fault system requires Personal Injury Protection for medical costs and lost wages,2Kentucky Department of Insurance. No Fault Rejection/Verification (PIP) plus minimum liability limits for bodily injury and property damage to others.3Kentucky Transportation Cabinet. Mandatory Insurance Neither pays for damage to your own vehicle.
What triggers the zero-deductible glass rule is comprehensive coverage, which is optional. Comprehensive protects against hail, falling debris, vandalism, animal strikes, and similar non-collision damage. Because the statute strips the deductible off any glass claim under a comprehensive policy, adding comprehensive coverage effectively gives you free windshield repair and replacement.
Some insurers sell a separate “full glass” endorsement, but in Kentucky the statute already eliminates the glass deductible under comprehensive, so the endorsement is largely redundant unless you want glass coverage without a full comprehensive policy.
What Makes a Windshield Legal in Kentucky
KRS 189.110 requires every motor vehicle on public roads to have a windshield “in a fixed and upright position” equipped with safety glazing that meets federal standards.4Kentucky Legislative Research Commission. KRS 189.110 – Unobstructed Windshields, Display of American Flag, Windshield Wipers Motorcycles and farm implements are exempt. The vehicle must also have a working, driver-controlled windshield wiper system.
The same statute restricts what you can attach to the glass. You may display documents that law requires you to show. You may run a transparent sunscreening strip along the top of the windshield, provided it does not encroach on the driver’s forward view. Any tint applied to the windshield itself must allow at least 70% light transmittance and cannot be red or yellow.
A chip or crack does not automatically violate KRS 189.110 unless it compromises the safety glazing or obstructs the driver’s view. Officers in the field often treat severe windshield damage as an equipment violation regardless, so prompt repair is the safer course.
Fines for Windshield Violations
General windshield and equipment violations under KRS 189.110 carry a fine of $20 to $100 per offense under KRS 189.990. Court costs are added on top, so the amount you actually pay will be higher.
Illegal windshield tint is treated more seriously. Applying tinting material that does not meet the 70% transmittance requirement, or using prohibited colors, is a Class B misdemeanor under KRS 189.110(9), with a maximum fine of $250.5Kentucky Legislative Research Commission.

You Choose the Repair Shop
Kentucky prohibits insurers from forcing you to use a specific auto glass shop. Your insurer can recommend a shop or maintain a preferred network, but the final choice is yours, and the insurer cannot require you to travel an unreasonable distance for an estimate or the repair itself.
If an insurer pressures you to use a particular vendor or hints that your claim depends on it, you can file a complaint with the Kentucky Department of Insurance. Most glass shops in the state are used to working directly with carriers, so the paperwork side generally runs smoothly regardless of which shop you pick.
ADAS Recalibration After a Replacement
Newer vehicles often have a forward-facing camera mounted behind the windshield that powers automatic emergency braking, lane departure warnings, and adaptive cruise control. Replacing the windshield changes the camera’s alignment, because the new glass has slightly different bend and clarity characteristics, and the vehicle cannot recalibrate itself.
A camera off by a single degree miscalculates distances by roughly eight feet at 100 feet away. At 30 mph, where stopping distance runs about 89 feet on dry pavement, that margin matters. Recalibration typically costs between $300 and $600, depending on whether the system needs static calibration in a controlled shop, dynamic calibration on the road, or both.
Not every policy explicitly folds recalibration into a glass claim. Ask your insurer before scheduling the work. Some carriers include it; others treat it as a separate charge. Skipping it on an ADAS-equipped vehicle is not a real option.
Commercial Vehicles Have Stricter Rules
If you drive a commercial motor vehicle, federal rules under 49 CFR 393.60 layer on top of Kentucky law. The windshield must be free of discoloration or damage in the driver’s primary viewing area, which extends upward from the top of the steering wheel to within two inches of the windshield’s top edge, and inward one inch from each side edge.6eCFR. 49 CFR 393.60 – Glazing in Specified Openings
Within that zone, federal rules allow a single crack that does not intersect another crack, or a chip small enough to fit under a three-quarter-inch disc and at least three inches from any similar chip. Anything more can put the vehicle out of service at a roadside inspection.
Federal rules also govern what can be mounted on the glass. Antennas and similar devices cannot sit more than six inches below the upper edge, and must stay outside the wiper-swept area and out of the driver’s sight lines to signs and signals. Decals must stay within four and a half inches of the bottom edge and clear of the wiper zone.7eCFR. 49 CFR Part 393 Subpart D – Glazing and Window Construction Commercial vehicle tint has to meet the same 70% transmittance floor Kentucky applies to all vehicles.
What Replacement Costs Without Insurance
Out-of-pocket, a standard passenger windshield replacement generally runs $350 to $550. That assumes a common model without advanced features. Luxury vehicles, uncommon glass, and ADAS-equipped vehicles that need calibration can push the total past $1,000 once the $300 to $600 recalibration fee is added.
For drivers with comprehensive coverage, the statute wipes the deductible off the claim and the insurer pays the full cost.1Kentucky Legislative Research Commission. KRS 304.20-060 – Coverage for Motor Vehicle Glass Filing a glass claim generally does not increase your premium, though policies vary. Without comprehensive coverage, the full amount is yours to pay.
