What restrictions apply to tinted windows during inspection?

Tinted windows must meet state regulations regarding visible light transmission to ensure safety and visibility standards are upheld. Each state has specific rules dictating how much light can pass through tinted windows, often measured by the percentage of visible light transmission (VLT). This is critical because excessively dark window tint can reduce visibility, which can be dangerous while driving, especially at night or in inclement weather. The aim of this regulation is to protect both the driver and other road users by ensuring that visibility remains adequate.

Factory-installed tint is generally compliant with these regulations, but aftermarket tints can sometimes exceed the allowable limits. Therefore, during an inspection, the technician will measure the tint to ensure that it meets the state’s requirements. If the tint does not comply, the vehicle may fail the inspection until corrections are made.
