Window Tint
C.R.S. 42-4-227 — 27% light transmittance on every window but the windshield, and 4 inches at the top of it
No window but the windshield may be treated so that it lets through less than 27% of light. The rear windows may be darker if the front side windows and windshield let through at least 70%.
Who handles this in Colorado: legal aid programs and the state offices, listed in the Colorado directory.
Nontransparent material may run along the top of the windshield no more than four inches down, if it does not reflect glare into other drivers' eyes.
Driving with illegal tint is a class B traffic infraction. Installing it is a class A traffic infraction.
