The legal tint limit for every window position in Missouri (35% on the front sides), checked against your own film's VLT, with the medical exemption and what a ticket costs.
Missouri 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 Missouri window limit, or read the limits as they stand.
Only the front sidewing vents and the windows immediately left and right of the driver carry a VLT floor (35% ±3%). Windows behind the driver and the rear window are not restricted by §307.173.
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 Missouri 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 Missouri window tint reference, cited to Mo. Rev. Stat. §307.173.
How the Missouri tint rules work
Missouri keeps its tint rule narrow: it sets a floor of 35% (±3%) only on the front sidewing vents and the windows immediately left and right of the driver, and caps their reflectance at 35% (±3%). Everything behind the driver, including the rear window, is left to any darkness you like. The windshield stays clear apart from factory tint and the manufacturer strip across the top, and a physician’s permit can lift the front-window limit.
This checker applies the Missouri 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 Missouri window tint reference, cited to Mo. Rev. Stat. §307.173.
