Is ADAS calibration required by law after a windshield replacement?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
It is required by the vehicle manufacturer’s repair procedure rather than by any Michigan, Indiana or Illinois statute. The manufacturer specifies recalibration whenever the forward camera behind the glass is disturbed, and insurers generally pay for it as part of a covered replacement. Skyview recalibrates as part of the job, $95 to $300 out of pocket.
Calibration requirement myths
Calibration is optional because no state law requires it.
The manufacturer’s repair procedure requires it, and that procedure is the standard the work is held to. The absence of a state statute does not make skipping it acceptable.
Insurers will not pay for calibration.
When the replacement is a covered comprehensive claim, insurers generally pay for the calibration the manufacturer requires as part of the same repair.
A shop can skip calibration if the warning light stays off.
The systems can look active while reading the road wrong. The manufacturer’s procedure, not the dashboard, is what decides whether the aim is verified.
A manufacturer requirement, not a state statute
ADAS calibration after a windshield replacement is required by the vehicle manufacturer’s repair procedure. When the forward camera behind the glass is removed and refitted during the replacement, the manufacturer specifies recalibration to restore its aim — and that procedure carries the same weight as any other factory repair instruction.
Michigan, Indiana and Illinois do not have a statute that orders recalibration by name; the requirement comes from the vehicle manufacturer’s repair procedure, applied through the repair process, rather than from a state law that names windshield calibration by title.
In practice that distinction matters less than it sounds. A shop that skips the manufacturer’s calibration procedure leaves the camera working off an unverified aim, and the safety systems it feeds — lane keeping, automatic emergency braking, adaptive cruise — can read the road wrong. Insurers generally pay for the calibration as part of a covered replacement.
The manufacturer’s procedure carries the weight of a factory repair instruction, and following it is what keeps the safety systems performing as the automaker intended. A shop that treats calibration as optional is skipping a step the manufacturer wrote into the replacement process, and the camera’s aim is what suffers. Insurers recognize the procedure as part of the covered repair, so the calibration is generally billed alongside the glass rather than treated as an add-on the driver fights for.
Skyview recalibrates as part of the job
Skyview performs the calibration the manufacturer specifies as part of the replacement visit, at $95 to $300 out of pocket on top of the glass. The installation runs about 45 to 75 minutes, followed by a 30-minute safe drive-away period. This is general information, not legal advice.
More questions about calibration and the law
Is windshield calibration mandatory?
Yes — by the vehicle manufacturer’s repair procedure, which is the standard the work follows. None of the three states Skyview serves writes recalibration into its vehicle code, but the manufacturer requirement carries the same practical weight.
Do states require ADAS recalibration?
No state in the Midwest requires it by title. The requirement comes from the manufacturer’s repair procedure, applied whenever the forward camera behind the glass is disturbed.
Can a shop skip calibration?
A shop that skips the manufacturer’s procedure leaves the camera’s aim unverified, and the safety systems can read the road wrong even with no warning light. Skyview performs the calibration as part of the replacement visit.
