Bill > HB436

This bill modifies Maryland's vehicle laws regarding medical exemptions for enhanced window tinting by eliminating the previous two-year time limitation on medical exemption certificates. Currently, vehicle owners who need protection from the sun for medical reasons can obtain a written certification from a licensed physician to use window tinting with less than the standard 35% light transmittance. Under the existing law, these medical exemption certificates were valid for up to two years. The new bill introduces a key change: if a physician determines that the vehicle owner's medical condition is permanent, the medical exemption certification will now be valid indefinitely. This means individuals with permanent medical conditions requiring reduced sun exposure will no longer need to regularly renew their window tinting exemption. The bill maintains other existing provisions, such as requiring the certification to be in the vehicle when stopped by a police officer and prohibiting tinting on the windshield below certain lines. The changes will take effect on October 1, 2025, providing a clear timeline for implementation of the new, more flexible medical exemption policy.
