The New York State 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 percent 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.
• Rear side windows must also allow at least 70 percent of light from the outside to pass through the window if the vehicle is classified as a: station wagon, sedan, hardtop, coupe, hatchback or a convertible. A vehicle falls into one of these categories if it is labeled “Passenger Car” on the Federal ID label found on the left front door panel.
NYS Health Department regulations specify that medical conditions may be used to justify an exemption from the limits on light transmittance. Medical conditions that qualify for exemption include: porphyria, xeroderma pigmentosa or severe drug photo-sensitivity. If you have one of the medical conditions that require you to have tinted vehicle windows, you may request an exemption from the law using the DMV’s application for tinted window exemption (MV-80W).
