The legal tint limit for every window position in Massachusetts (35% on the front sides), checked against your own film's VLT, with the medical exemption and what a ticket costs.
Massachusetts 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 Massachusetts window limit, or read the limits as they stand.
Massachusetts regulates all five pieces of glass at 35% and adds no vehicle-class exception; a tinted rear window also requires two outside mirrors.
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 Massachusetts 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 Massachusetts window tint reference, cited to M.G.L. c.90 §9D; 540 CMR 4.04(8)(g).
How the Massachusetts tint rules work
Massachusetts keeps it uniform: every window that matters, the two front doors, the two windows behind them, and the rear windshield, has to allow at least 35% of light, with no SUV or van loophole for darker rear glass. Reflectance is capped at 35% too, so mirror-look film is out. The windshield takes tint only in the top 6 inches or above the AS-1 mark, a tinted rear window means the car needs two outside mirrors, and the whole thing is checked at the annual safety inspection.
This checker applies the Massachusetts 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 Massachusetts window tint reference, cited to M.G.L. c.90 §9D; 540 CMR 4.04(8)(g).
