If no AS-1 mark exists, how far below the top of the windshield can tint be applied?

The correct answer indicates that if no AS-1 mark is present on the windshield, tint can be applied up to 4 inches below the top of the windshield. This regulation is in place to ensure the safety of drivers and passengers by allowing adequate visibility through the windshield. The AS-1 mark is a standardized reference point that indicates the maximum allowable tinting above this line without affecting visibility restrictions.

By allowing tint application up to 4 inches below the top without the AS-1 mark, regulations attempt to balance aesthetics with safety, ensuring that drivers have a clear and unobstructed view of the road directly ahead. This standard may also help prevent legal issues related to vehicle modifications that could interfere with safe driving practices. Understanding these limits is crucial for inspectors to ensure compliance with state regulations and maintain vehicle safety on the road.
