Window tinting is a popular modification that car owners opt for not only for privacy reasons but also for aesthetic purposes, but how dark tinted can your vehicle windows be in Washington State?


Though window tinting can make your vehicle cooler and more stylish, it is essential to comply with the legal standards in Washington.

I saw that some states allow as much as 50% tinting but Washington's requirements are a lot more stringent.

I know of a few of my friends who got pulled over when we were teenagers for tinted windows. It seemed like an excuse for police to pull us over but there are reasons why too much tinting can affect your driving and line of sight in a vehicle.
