Windshield Recalibration: What Anyone Actually Has to Tell You
In nine states the shop has to tell you in writing whether your job needs an ADAS recalibration. No state requires the recalibration itself. If your car has cameras or sensors behind the windshield (lane keeping, automatic braking, adaptive cruise), replacing the glass can knock them out of alignment, and putting them back is called recalibration. The nine are Utah, Arizona, Florida, Maryland, Kentucky, Iowa, Louisiana, Virginia and New York. In the other forty-two jurisdictions, no law requires anyone to raise it at all.
The thing almost nobody says plainly: no state requires the recalibration. Every one of these laws regulates the telling, not the doing. A shop in the strictest state on the list can decline to recalibrate your car and still be fully compliant, as long as it says so in writing. What the laws add is that if the shop does perform one, it has to meet or exceed the manufacturer's specification, and it cannot bill you for one that was not done or did not work.
So the law is a floor under the paperwork, not under the repair. That is not a loophole: it is what a disclosure statute is. Knowing which one you are relying on is the whole point of this page.
The nine states where someone owes you a written answer
Utah, Arizona, Florida, Maryland, Kentucky, Iowa, Louisiana, Virginia and New York. They are not the same law and they do not give you the same recourse.
Three differences worth knowing before you rely on one:
- Florida's law has no private cause of action. The duty is real and the state can enforce it. You personally cannot sue under it. A law existing is not the same as a law you can use.
- Utah's follows the car. If someone knowingly sells a vehicle whose driver-assist system is inoperable or was never recalibrated, without telling the buyer in writing, the buyer gets a claim worth at least $1,500. Every other law here stops at the repair counter. If you are buying a used car, this is the only state where the statute is looking out for you rather than for the person who had the glass replaced.
- Arizona makes the shop tell your insurer too, not just you, when a recalibration is skipped or fails.
Who you complain to also differs, and it is not intuitive: the Attorney General in Kentucky and Virginia, the insurance regulator in Iowa and Louisiana, the consumer-protection statute in Maryland, a graduated fine in New York starting with a warning.
What to ask for, in any state
None of this depends on where you live. In the forty-two jurisdictions with no ADAS disclosure duty, these are still perfectly reasonable things to ask, and a good shop will already be doing them. (Fifteen of those forty-two do have a glass law; it just says nothing about calibration.)
- Does my car have driver-assist systems that sit behind the windshield? Worth asking even if you think you know, the same model year often ships with and without them. No law anywhere tells a shop how to determine this, so it is the step most likely to be skipped.
- Does this job require a recalibration?
- Are you doing it here, or sending it somewhere? Both are normal answers. "Neither" is also an answer, and it is one you want in writing.
- Will you confirm in writing that the work met the manufacturer's specification?
- If the recalibration does not succeed, will you tell me in writing, and what do I do next? In Utah the shop must additionally point you to a dealership or qualified facility. Elsewhere, ask.
Keep the answers. A written statement is worth something in all fifty states: as a record, as leverage with an insurer, and as evidence if the car later behaves oddly. In nine of them it is also a legal duty.
Two things people get wrong
"The law says I have to get OEM glass." It does not, anywhere on this list. Maryland says the opposite in as many words: the shop "is not limited to" glass, tooling, equipment or repair procedures from the vehicle manufacturer, provided the recalibration meets or exceeds specification. The duty is about the result, not the brand of the part. A widely repeated claim that Texas requires OEM glass traces back to an unrelated parts bill that never passed.
"My insurer has to pay for the recalibration, so the shop has to do it." Those are two different rules binding two different parties, and neither one creates the other. What an insurer must pay varies enormously (a guaranteed floor in some states, a lowest-estimate cap in others), and none of it obliges the shop to perform anything, or obliges anyone to tell you about it. When the disagreement is whether the insurer will pay for a required calibration at all, here is how that dispute works and what recourse you have.
Where this comes from
Everything above is a plain-language summary of our fifty-state page, which is where the citations live: Auto glass disclosure laws by state. Every state's row there is linked to its own statute or bill record, and each row says how strong the evidence behind it is.
This page deliberately carries no separate source list. A summary with its own citations is a second copy of the truth, and second copies go stale quietly. If a rule here matters to you, follow the link and read the row.
