Maryland window tint rules
In Maryland, tint added after manufacture needs at least 35% light transmittance on front side windows of passenger cars, station wagons, light trucks, vans and multipurpose passenger vehicles. Behind the driver, only passenger cars and station wagons need 35%, so an SUV depends on its registration class. Added windshield tint is barred below the AS-1 line or 5 inches from the top, whichever is less. Limousines, school vehicles and heavy or large vehicles differ.
Summary checked against Md. Code, Transp. § 22-406(i); COMAR 11.14.02.14D, 11.14.04.16D and 29.02.01.11F on 2026-09-19. Verify current statutes before quoting.
