Window Tinting Laws and Guides

During the last 3-4 years the Glass and Glazing Federation (GGF) and other leading window film manufacturers have been putting forward their views, to obtain a clear definition on the law of window tinting. However, as of January 2004 the government has rewritten the law to incorporate a tint level of seventy percent visible light transmission on the front driver and passenger side windows.

Vehicles 10 years and older already have this level of tint is manufactured within the glass from the vehicle manufacturers. This means that if any window tinting company or manufacturer installs films to the front driver or passenger side windows or front quarter windows, they are in infringement of the law.

State-by-state tinting laws vary, but tinting is legal in most states. What many states put restrictions on is how dark the tinting can be, because it affects visibility. It’s common to have a mandatory minimum visible light transmission (VLT) measurement, which is typically certified by the dealer or professional who handles your tinting. These measurements can vary based on the windows of the car, or states can require additional mirrors in exchange for tinting. People with disabilities that affect eyesight can sometimes have these requirements waived with certification from their doctor.
