Texas Vehicle Inspection & Window Tint: How Medical Exemptions Work
Texas requires annual vehicle inspections where tint is tested. Without a medical exemption, non-compliant tint means an automatic inspection failure. Here's how to stay legal.

Medically ReviewedDoes Texas Check Window Tint During Vehicle Inspection?
Yes. Texas annual vehicle safety inspections — required by the Texas Department of Public Safety — include a window tint check as part of the lighting and glazing inspection items. Inspectors use calibrated VLT (Visible Light Transmission) meters to test front side window tint. If your front windows transmit less than 25% light, your vehicle fails.
A failed inspection in Texas means you cannot legally register or renew your vehicle registration for the following year — a serious compliance problem beyond just a traffic citation.

How a Medical Exemption Affects Your Texas Inspection
Under Texas Transportation Code §547.613(c), a licensed Texas physician can authorize darker tint for medical reasons. When you present your exemption documentation to an inspection station, the inspector notes the exemption and passes your vehicle — even if the front side windows transmit less than 25% VLT.
The exemption must be:
- Signed by a licensed Texas physician
- Clearly state the medical necessity for darker tint
- Present in the vehicle during the inspection
- Presented to inspection station personnel before the tint test
Why This Matters for Annual Registration
Texas vehicle registration is tied to inspection status. Without a passing inspection sticker, your registration lapses. This can result in additional traffic citations on top of any tint violation fine. A medical exemption solves both problems: it protects you at traffic stops and ensures your vehicle passes annual inspection.
