Is light transmittance measurement necessary for a strip of tint above the AS-1 or AS-5 mark on a NEV?

The requirement for measuring light transmittance in relation to window tinting on a Neighborhood Electric Vehicle (NEV) is determined by specific regulations regarding vehicle modifications. In this case, it is stipulated that if a strip of tint is placed above the AS-1 or AS-5 mark on the windshield, it does not require a light transmittance measurement.

This is because the AS-1 and AS-5 markings indicate predefined areas on the windshield where tint is permissible without the need for compliance checks regarding light transmittance. These markings are standard indicators used for safety compliance, guiding where tint can legally be applied without affecting driver visibility or safety standards.

It's important to note that while general tint regulations may require compliance checks in other areas or under different circumstances, the specific context of the AS-1 and AS-5 marks provides an exception for NEVs, in this instance eliminating the need for measurement above those designations. Therefore, it is affirmed that such measurements are not necessary in these specified areas, recognizing the legislative intent to balance aesthetic modification with safety requirements.
