What document must be carried in the vehicle for a medical tint exemption?

The requirement to have a Physician's Written Medical Statement in the vehicle for a medical tint exemption is grounded in Texas law. When individuals have a medical condition that necessitates a darker tint on their vehicle windows for health reasons, they are required to obtain and carry a statement from a licensed physician. This document serves as proof of the medical necessity for the tinted windows beyond the standard limits set by regulations.

The presence of this statement in the vehicle ensures that law enforcement and inspection personnel can verify the legitimacy of the medical tint exemption if questioned. It is crucial for compliance with safety inspection regulations and helps prevent potential misunderstandings regarding the legality of the vehicle's window tinting.

In contrast, other documents such as an insurance policy document, vehicle registration card, or driver's license do not specifically address the need for medical tint exemptions and do not provide the necessary validation for the tint beyond standard regulations.
