If your car is from about 2018 or newer, chances are the shop that replaces your glass will also charge to re-aim the camera behind the mirror. Here is what that camera does, why the re-aim is its own bill, and the one state where the law says who pays for it.
Look up at the rear-view mirror in a newer car. Behind it, pointed out through the glass, is a small camera. That camera is the eyes for a group of safety features that carmakers call lane keep assist, forward collision warning, adaptive cruise control, and automatic emergency braking. Every time it takes a picture, the car assumes the camera is pointed in exactly the direction the factory set it.
New glass changes that. Even a windshield installed perfectly sits a hair differently than the last one did, and a hair is enough to throw the aim off by feet at the end of the road. So after the glass goes in, the shop has to re-aim the camera against a known target. That job is what the industry calls calibration; on your invoice it usually says "ADAS calibration" or "camera recalibration."
Two reasons. First, it needs different equipment than glass work: a target board, a level floor, sometimes a road test with a scan tool plugged in. Many glass shops send the car to a sublet calibration shop or a dealer for it, and pass that bill through. Second, insurers pay for glass and for the re-aim under separate labor codes, so the shop has to itemize them for the claim to go through cleanly. Our windshield claim calculator shows the two amounts on separate lines for the same reason: they are two decisions, and lumping them together hides money.
Shops do the re-aim in one of three ways, depending on what the carmaker's service manual demands for your car:
Which one your car needs is not your call and not the shop's call. It is written in the service procedure for your make, model, and year. A good shop will look it up before quoting.
For a cash customer paying out of pocket at an independent shop, a single re-aim (static or dynamic) usually lands around $300, give or take about $150 in either direction. Dual calibration is a different bill: it commonly runs $500 to $600 or more. Dealer prices are often higher again. Our calculator uses a single sample-data estimate around $300 for the re-aim line; if your car needs dual, our number is low.
Our $300 figure is a sample-data estimate based on shop invoices we have seen; unlike our glass prices, this one is not pulled live because no calibration marketplace publishes prices by vehicle. It updates as our shop network reports back.
The share of new cars that need a re-aim after glass work jumped over the last decade, and it is close to universal now on new inventory. AutoBolt data reported by the auto-glass trade press (glassBYTEs, 2023) put the share around 25% of model year 2016 vehicles and about 89% of model year 2023 vehicles. If your car is a 2019 or newer mainstream model, expect a re-aim on the invoice. If it is a 2013 base trim, expect not to. Between those, ask the shop up front so it does not appear as a surprise line item after the job.
If you file a comprehensive claim, most insurers cover the re-aim as part of the covered windshield loss, because the car is not safe to drive without it. Most, not all, and rarely with a written rule. That is where state law starts to matter, and two states are worth knowing by name.
Kentucky is the one state whose glass statute names calibration. A 2024 amendment to KRS 304.20-060 (2024 SB 29, effective April 2, 2024) writes camera recalibration into the state's $0-deductible mandate for glass-only claims. In Kentucky, the re-aim is covered at no deductible, by statute, in black and white. Our full Kentucky glass law breakdown covers the one condition that comes with it (glass-only means only glass; a hail claim with body damage is different).
Florida's law is genuinely unsettled on this point. Fla. Stat. § 627.7288 waives the deductible on windshield claims, but the statute predates cameras behind mirrors and does not mention calibration by name. No Florida statute, regulator bulletin, or appellate decision that we can point to says whether the waiver covers the re-aim. In practice most carriers pay it as part of the covered loss, but if you want a rule to hold them to, there is not one to cite. Our Florida glass law page covers this in more detail. Ask before you book: "Is the camera re-aim included in the windshield claim at no deductible?"
Everywhere else, whether the re-aim rides on the claim without a second deductible comes down to your carrier's practice, not a state rule. Ask that same question.

Our calculator asks whether your car has the camera, prices the glass live from local shops, applies your state's rule, and shows the re-aim on its own line so you can see both decisions clearly. If you are in Kentucky or Florida, it uses your state's specific rule instead of a national average.
