From where are measurements for windshield brow tint taken?

Measurements for windshield brow tint are taken at the windshield from the outside of the vehicle. This is critical to ensure compliance with regulations regarding tint levels, which are specifically designed to enhance visibility and safety for the driver. The brow tint should be evaluated from the exterior as this reflects the actual conditions that affect driving visibility, ensuring there are no obstructions when looking through the windshield during daytime and nighttime operations.

Taking measurements from inside the vehicle would not provide an accurate representation of how the tint affects visibility from an external perspective, which is essential for proper safety inspection. Assessing the tint restrictions realistically involves understanding how outside light interacts with the tint when observed from various angles, which can only be correctly evaluated from the outside of the vehicle.
