California Tint Laws

The Tint Pros has many shades to choose from, including the California legal film for the front door windows, which comes with a certificate of compliance.

The California law states that you may tint your rear side windows and the back window as dark or as light as you want as long as you have a rear view mirror on both sides of the vehicle. Your front driver and passenger door windows must have a minimum of 70% visible light transmission (VLT) with or without film. Most cars have a very slight factory tint integrated into the glass (approx. 12% shading / 88% VLT) which does little to block heat or harmful UV rays. Our 85% VLT film, combined with the minimal shading currently in the factory glass will be below the legal limit of 70% VLT required by law. The Tint Pros provides you with a certificate of compliance along with your warranty card and care instructions.

What Is VLT?

Visible Light Transmission (VLT) refers to the amount of visible light allowed to pass through a window from its exterior. This means that the lower the percentage of VLT, the less light that is able to transmit through the glass. For example, 5% is “limo,” the darkest shade of tint.

How Do I Calculate VLT?

First, you have to account for current VLT when installing aftermarket tint. If you were to put window film with a 70% VLT on your front windows, which by itself would be legal in CA, your windows would still end up being illegally tinted at around 60% VLT , which is under the 70% threshold. The darkest film you can use while staying legal is about 90% VLT. You can purchase a meter to measure the VLT of your tint, or if you’re unsure of the legality of your tint, bring your car to us and we will measure your VLT for free!

Can You Get Fined In Other States?

The answer to this varies from state to state. Some states provide exemptions for visitors while others do not. States with no visitor exemptions may issue you a repair order and/or a fine if your window tint does not meet their regulations or the regulations for the state in which the vehicle is registered. In some cases, it is possible to contest a ticket or repair order and have it thrown out. Regardless, you are expected to follow the laws of the state in which your vehicle is registered in and check individual state laws for more information regarding their laws and exemptions before traveling. The Tint Pros is not liable for your decision to have film that is not legal in various states installed on your vehicle.
