Which document can serve as proof of a vehicle’s compliance for tinting medical exemptions?

The document that serves as proof of a vehicle’s compliance for tinting medical exemptions is the Physician's Written Medical Statement. This statement confirms that the individual has a medical condition that necessitates the need for darker window tinting beyond the legal limits. It serves as an official medical justification, making it valid for use when applying for a medical exemption for window tint restrictions under Texas law.

The other documents, such as a certificate of insurance, a registration document, or a vehicle title, do not provide the necessary medical justification. A certificate of insurance primarily serves to prove that a vehicle is insured. A registration document indicates that a vehicle is properly registered with the state, while a title shows ownership of the vehicle. None of these documents contain the specific medical information required to support an exemption request based on a physician's recommendation.
