Section 375 (12-a) of the NYS Vehicle and Traffic Law does not allow a windshield or front side windows that are dark. The windshield and front side windows cannot block more than 30% of the light. Seventy percent or more of the light from the outside must pass through the window. This law also applies to the rear window unless the vehicle has outside rear-view mirrors on both sides. The mirrors must give the driver a full and clear view behind the vehicle.

If the vehicle is classified as a station wagon, sedan, hardtop, coupe, hatchback or convertible, the rear side windows must also allow at least seventy percent of light from the outside to pass through the window.
