Window tint laws in Connecticut (2026)

The rules, window by window

Windshield

Tinted material on the windshield is limited to the area above a defined line; the statute uses a positioning standard measured 29 inches above the undepressed driver's seat, consistent with an AS-1 line style top strip allowance.

Reflectivity

The statute sets luminous reflectance limits alongside the transmittance standard: 27 percent (plus or minus 3 percent) for front side (wing vent) glazing, and 21 percent (plus or minus 3 percent) for rear side windows and the rear window. Re-confirmed word-for-word against two independent full-text reproductions in this pass; the figures were not garbled.

Medical exemption

A person required for medical reasons to be shielded from direct rays of the sun (or any person operating, or usually a passenger in, that person's vehicle) is exempt from the transmittance/reflectance provisions, with written documentation from a physician or optometrist licensed in Connecticut.

Enforcement

Compliant tinted windows must carry a sticker legible from outside the vehicle, affixed to the lower left corner, certifying compliance. Transmittance values carry a plus or minus 3 percent tolerance.

Notes

RE-VERIFIED, figures confirmed accurate. Passenger car (sedan) values: 35 percent minimum total light transmittance, plus or minus 3 percent, for front side and for rear side and rear windows; luminous reflectance capped at 27 percent (plus or minus 3 percent) for front side wing-vent glazing and 21 percent (plus or minus 3 percent) for rear side/rear glazing. Trucks, motor buses, trailers, mobile manufactured homes, and multipurpose passenger vehicles (SUVs and vans) may have windows behind the driver tinted darker if the vehicle has outside mirrors on both sides reflecting a view of the highway for at least 200 feet. The statute phrases the standard as total light transmission, indicating combined glass plus film measurement. On the flagged gap: the previously-recorded 27%/21% reflectance figures were re-read carefully against a full re-fetch of CGS 14-99g in this pass and confirmed correct verbatim ('luminous reflectance of twenty-seven per cent plus or minus three per cent' for front side wing vents; 'luminous reflectance of twenty-one per cent...plus or minus three per cent' for rear side windows) -- the figures were not, in fact, garbled; the earlier flag reflected caution about a full-text-reproduction source rather than an actual transcription error. The official cga.ct.gov portal still failed a direct TLS fetch in this pass, so the re-verification again relies on the FindLaw full-text reproduction, cross-checked against a second independent reproduction/summary source.
