What windows are not allowed to be tinted without a certificate?

The correct choice is that front driver and passenger windows are not allowed to be tinted without a certificate. This regulation is in place to ensure visibility and safety on the roads. The driver and front passenger windows are crucial for the driver’s ability to see other vehicles and pedestrians and to ensure safe driving conditions.

Additionally, state laws commonly regulate the amount of tint that can be applied to these windows to maintain transparency. For example, it is typically required that front windows maintain a certain level of light transmittance to prevent impairing the driver's vision.

While rear windows can often have tint applied, as they do not directly affect the driver's field of vision, the front windows are treated more strictly to uphold safety standards. This is why any tinting on the front driver and passenger windows requires official approval or certification to ensure compliance with state laws.
