The Tint On Your Windows
Transp. § 22-406 — at least 35% light transmittance, and a repair order with the citation
In Maryland, tinting material added after a vehicle is manufactured must allow a light transmittance of at least 35% through the window. For the registration classes the subsection names under § 13-912 that applies to any window; for those under §§ 13-913, 13-917 and 13-937 it applies to the windows immediately left and right of the driver.
A citation and a repair order. An officer who sees a violation may stop the driver and, along with a citation, issue a safety equipment repair order.
Installers. A person may not install window tinting material that does not meet the light transmittance requirement.
A physician's certification. A person who must be protected from the sun for medical reasons is exempt if the owner has in the vehicle a written certification from a physician licensed in the State, in the form the State Police require. It lasts as long as the physician determines, up to 2 years, or indefinitely for a permanent condition.
Safety glass standards, easily removable materials and the repair order process are not all on this page. Whether a particular film passes, and how a reading was taken, are questions for a licensed Maryland attorney.
