What Is a Massachusetts Tint Medical Exemption?
A medical exemption is a physician-certified document that authorizes you to have darker window tint than MGL c.90 §9D normally permits. Massachusetts requires 35% VLT on all side and rear windows for sedans. With a valid exemption, you can legally go darker on all applicable windows — and your vehicle will pass the annual safety inspection.
Massachusetts has one of the highest physician-per-capita ratios in the country, with world-class medical centers including Mass General Hospital, Brigham & Women's Hospital, Dana-Farber Cancer Institute, and Beth Israel Deaconess — all treating the conditions that commonly qualify for tint exemptions. Our service bridges the gap between your existing medical documentation and the state's exemption requirements.
Who Qualifies for a Medical Exemption?
Any Massachusetts resident with a documented medical condition causing sensitivity to light or vulnerability to UV radiation may qualify. Boston's diverse population includes communities with elevated prevalence of qualifying conditions:
Boston's large Caribbean community (Dominican, Haitian) has elevated lupus prevalence. The university population (Harvard, MIT, BU, BC, Tufts) reports high rates of photophobia and migraines from screen-intensive work. Massachusetts also has high MS prevalence due to its northern latitude.
