Colorado Window Tint Checker (2026)
The legal tint limit for every window position in Colorado (27% on the front sides), checked against your own film's VLT, with the medical exemption and what a ticket costs.
Colorado window tint checker
VLT (visible light transmission) is the share of light the film lets through; a lower number is darker. It is printed on the film packaging or your installation receipt. Leave it blank to just read the limits.
Enter your film's VLT above to check it against each Colorado window limit, or read the limits as they stand.
The rear window may be darker than 27% only when the front side windows and windshield allow at least 70% (§42-4-227(1)(a)(II)).
Film is sold by its own VLT, but police measure the installed darkness: the film combined with your factory glass, which reads darker than the film alone. These are the Colorado figures stated as information, not a determination about any stop or ticket.
Informational only, not legal advice. Reflectivity limits, color bans, and vehicle-class exceptions can change the answer for a specific car. See the full rules, the exemption steps, and the citations on the Colorado window tint reference, cited to C.R.S. §42-4-227.
How the Colorado tint rules work
Colorado’s 27% rule comes with a trap and a surprise. The trap: rear windows may only go darker than 27% when the front doors and windshield are essentially untinted (≥70%). The surprise: unlike almost every neighbor, Colorado offers no medical exemption at all; no doctor’s letter changes the limits.
This checker applies the Colorado figures to the VLT you enter. It is informational only and not legal advice: reflectivity limits, color bans, and vehicle-class exceptions can change the answer for a specific car. For the full rules, the shades table, and the citations, see the Colorado window tint reference, cited to C.R.S. §42-4-227.
