Will dark tint fail Texas inspection?

Front side windows darker than 25% VLT can fail unless you have a valid medical exemption. Rear windows have no darkness limit.

Do I need to carry paperwork?

If you have a medical exemption, keep the signed statement in the vehicle. Some drivers also keep the film's certification on hand.

What is the darkest legal tint in Texas?

For most passenger vehicles in Texas, the front driver and passenger side windows must allow at least 25% visible light transmission when the film is measured together with the original glass. That 25% VLT front-window limit is the darkest legal shade for the front sides. Windows behind the driver are generally exempt, so rear side glass can go darker, and windshield tint has its own AS-1-line placement rules.
