How Much Can I Tint My Windows Legally?

Legal Window Tint

Window tint is a desirable option in vehicles today, whether it’s for a new, used, or classic car. It provides:

  • Enhanced privacy in your vehicle
  • A cooler interior
  • Protection from ultraviolet rays
  • An aesthetically-pleasing look
  • Protection from the sun’s glare

Many new vehicles come equipped with some level of tint in the window glass itself, though a few still come with clear, untinted glass. If your vehicle is untinted you can opt to have window tint installed, and if you have factory-equipped tint you may choose to have your windows tinted darker. In either case, window tint can be applied by either an aftermarket tint installation professional or as a do-it-yourself kit.

How dark can you go?

Window tint is measured as a percentage of the light that can pass through the window. Every state or county is able to set their own law on an allowable tint limit. The common allowable limits are 50 percent for the driver’s front and passenger’s front window, and 35 percent for the rear passenger or side windows and the rear windshield. What that means is that the front windows will allow more light through the window tint than the rear windows, though the difference in appearance is negligible.

There are a couple reasons why window tint darkness is regulated. If your window tint is too dark, you are not able to see well enough out of your windows to drive safely at night. You have a higher likelihood of causing an accident or hitting a pedestrian. Also, law enforcement needs to be able to see the occupants of a vehicle during a traffic stop to ensure their own safety. If the window tint is too dark, they are not able to clearly identify any dangers that may be in the vehicle.

Law enforcement can perform a traffic stop and pull you over if they believe your windows are tinted too dark. They are equipped with a tool that performs a tint measurement, and gauges the darkness of your tint as a percentage. If your tint is too dark, you can be fined and required to have the film removed or replaced to be within the acceptable limits.
