How to check window tint darkness
Tinted windows must be checked for compliance with local laws. (reflections image by Furan from Fotolia.com)

While some think of tinting windows as a driver's way of trying to look cool, there are actually multiple potential benefits. Tinted windows block up to 99 per cent of ultraviolet rays from the sun, and they help prevent a car's interior from overheating. Tinting reduces the glare that can occur from other headlights and from the sun's reflection off of snow. Since there are different state laws about tinted windows, you should periodically check the tint to make sure it meets the standards.

Instructions

  1. 1

    Purchase a Model 100 tint meter or a similar tint-measuring tool. Call your local law enforcement agency to determine the law in your state.

  2. 2

    Roll the car window you wish to test about halfway down and slip the tint meter over the window using the slot in the middle of the device. The tint meter will begin the test immediately without needing to press another button.

  3. 3

    Look at the tint meter's digital display. The device will give you a percentage of visible light transmission (VLT) for your car's window. Several states have up to 50 per cent VLT limits for tinted windows while others have no laws at all.

Tips and warnings

  • Test the device on a window that is clean and has few scratches. Dirt and scratches can affect the readings on the device.
  • If you do not wish to purchase a tint meter, you can call your local law enforcement agency and ask if they can test the level of tint for you.
