Maryland’s Chapter 452, approved May 13, 2025, gave an indefinite term to a vehicle owner’s medical tint certification when the licensed physician determines that the medical condition is permanent. The change took effect October 1, 2025.
That is a change to the duration of qualifying paperwork. It does not make every medical tint exemption permanent or remove the need for documentation. The current Transportation Article §22-406 requires the certification to describe the owner’s medical need, follow the State Police division’s required format and come from a physician licensed in Maryland.
The owner must have the written certification in the vehicle when police stop it. The statute also preserves windshield restrictions, so an indefinite certificate should not be read as permission to cover any part of the windshield.
For installers and customers, the useful question is whether the certification actually records the permanent-condition determination. This historical change concerns qualifying certificates, rather than a blanket reduction in Maryland’s ordinary tint threshold.
