Are you looking to get your windows tinted but keep them legal? The regulations for car window tint differ from SUV tint laws, and knowing what is allowed can be confusing.
Our guide covers everything you must know to stay compliant, avoid tickets, and avoid paying to have the tinting redone.
WA state window tint law is based on the concept of Visible Light Transmission (VLT), the percentage of outside light that can pass into your vehicle. The greater the percentage of light that can pass through the glass, the higher the VLT number.

Washington Headlight and Taillight Tint Laws
As defined in WAC 204–21–230, it is important to avoid adding aftermarket decorations or modifications that obstruct the headlamp lens or other lighting devices on motor vehicles. This includes features like tinted plastic covers, grilles, or slotted covers that can reduce the effectiveness of the lighting equipment.
Medical Exemption
You do not need to fill out any forms or submit anything to get a window tint medical exemption. Instead, you must carry a written verification from a licensed physician explaining why you need the exemption in your vehicle. Always keep this verification in your car and show it to law enforcement if they ask for it.
