HB 436 Maryland House of Delegates · 2025 Regular Session

Vehicle Laws - Medical Exemption for Enhanced Tinted Windows - Time Limitation

HB 436 repeals the 2-year expiration requirement for medical exemptions allowing tinted windows with less than 35% light transmittance in Maryland. It directly affects residents with medical conditions requiring enhanced window tinting (e.g., photosensitivity), who previously needed to renew certifications every two years. The bill removes the time limit from Section 22-406(i)(4)(ii) of the Maryland Annotated Code, allowing exemptions to remain valid as long as the medical need persists. This change simplifies the process for affected drivers by eliminating the need for periodic renewal. The bill takes effect October 1, 2025.

MODERATE

The bill was amended to clarify that medical exemptions for enhanced tinted windows apply specifically to vehicle owners with permanent medical conditions, and to allow written certifications to be valid indefinitely for those with permanent conditions rather than being limited to a maximum of 2 years.

Scope change

The bill's scope was narrowed to explicitly target vehicle owners with permanent medical conditions, and the duration of medical exemptions was expanded from a maximum of 2 years to indefinite for permanent conditions.

ELIGIBILITY

Added explicit reference to 'permanent medical conditions' in the bill title and purpose to clarify that the exemption applies specifically to permanent medical needs rather than temporary conditions.

REQUIREMENT

Changed the validity period of medical certifications from a maximum of 2 years to indefinite for vehicle owners whose licensed physician determines their medical condition is permanent.

Added a new provision stating that if a licensed physician determines the owner's medical condition is permanent, the written certification for enhanced tinted windows shall be valid indefinitely.

Removed the 2-year time limitation on medical exemptions for enhanced tinted windows, which previously capped the validity period regardless of the underlying medical condition.
