The rules, window by window

WindowRule
Front side windowsMinimum 27% VLT
Rear side windowsMinimum 27% VLT
Rear windowMinimum 27% VLT

Windshield

The windshield must allow at least 70 percent light transmittance. Nontransparent material may be applied to the topmost portion of the windshield if its bottom edge extends no more than 4 inches measured down from the top of the windshield, is not red or amber, does not distort vision, and does not reflect sunlight or headlight glare excessively.

The standard in the law's own words

The windshield strip material must not distort vision or contain lettering that obstructs the driver's view.

Reflectivity

No material may be used on any window of the motor vehicle that presents a metallic or mirrored appearance (CRS 42-4-227).

Color restrictions

The windshield top strip material must not be red or amber in color.

Medical exemption

No medical exemption provision appears in CRS 42-4-227 as reviewed. Colorado is commonly described as having no tint medical exemption; a reviewer should confirm no exemption exists elsewhere in the statutes.

Enforcement

Standard violations are a class B traffic infraction. Installing window material that violates the transmittance requirements is a class A traffic infraction.

Notes

The general floor for side and rear windows is 27 percent light transmittance. Windows to the rear of the driver may have less than 27 percent transmittance only if both front side windows and the windshield meet a 70 percent light transmittance standard; in that configuration the rear side windows and rear window have no numeric floor. Colorado does not use a sedan versus MPV/SUV class distinction for tint limits. The statute text reviewed did not state a net-film versus combined-transmittance measurement method or a numeric enforcement tolerance. This summary is informational and is not legal advice.
