Understanding the Maximum California Legal Window Tint

What is Automotive Window Tint?

Window tinting is a process of adding a thin, transparent film to the windows of a car, primarily to reduce the amount of visible light that passes through, although it can also offer privacy, reduce heat and protect against UV rays. It is important to note that these features may vary based on the type of tinted film used, and that tint darkness is regulated by law. There are many different types and categories of window tints, ranging from non-reflective to reflective and from dyed to metalized. Typically, the average owner of motor vehicles chooses polyester dyed window tint which is available in size-specific precut rolls . Dark window tint tends to be less expensive than other types of window tint, and is most effective at reducing glare and absorbing heat. Reflective window tint contains metallic material which blocks light and reflects it away from the vehicle through the glass. Its benefits as compared to dyed tint include temperature control and visibility reduction. However, while reflective window tint is suited for trucks and SUVs as it creates a mirror effect, it is not recommended for sedans and other vehicles, as it can significantly decrease the driver’s ability to see outside the vehicle and can cause accidents. In California, reflective window tint is illegal.

California Law for Your Window Tint

California permits a range of tint darkness (VLT) percentages on car windows. While this is often linked to UV protection, notable exceptions to the rule of the darker the tint, the higher the cost exist. The window tint you choose for your car also matters. For example, the VLT percentage of tint will affect the amount of light visible through the tinted window. Reputable manufacturers offer clearer windows with any tint reflective coating. In the case of VLT, the film should come with a layer to add comfort during UV absorption and heat reflection.
The basic rule is the dark the windows the higher the price tags tend to be. Tint film is measured by the amount of VLT, which represents the amount of light that can penetrate the film. Simply put, the lower the rating the darker the tint. As an example, a tint with a VLT of 5% permit 5% of the light to pass through. Conversely, a tint with a VLT of 50% permits 50% of light to pass through.
California allows the below tint percentages:
• Windshield: Any darkness can be used above the AS-1 line or the top five inches from the top of the windshield. A non-reflective film is mandatory.
• Front side windows: Must have at least a VLT of 70%
• Back side windows: No restrictions on the level of darkness
• Rear window: No restrictions on the level of darkness
• Side mirrors: Must have a VLT of at least 70%

Legal Window Tint Penalties

As with most things, tints are all about the details. And, unfortunately, asking for a little extra detail can get you into hot water. If a police officer were to notice that your window tint appears darker than California law allows, they won’t hesitate to pull you over and hand you a ticket. Whether or not you tried to cheat the system, whether or not you can legally prove that your tint is in compliance, and whether or not the officer is correct in their assumption means nothing. You’re going to get a ticket, and there’s nothing you can do about it. Additionally, if you receive a warning, you are required by law to replace non-compliant window film within ten days of receipt. If you’re pulled over again before doing so, you could receive a second ticket, which would result in a fine of $25 for the second offense and a misdemeanor on your criminal record. The penalties for failing to comply with window tint laws are two-fold: a monetary fine of $1975 (which is a whole lot of money to pay for something that actually costs a great deal less), and a misdemeanor that would go on you criminal record. So, while the temptation to break the law stipulating tint requirements in your car is understandable, it is often not worth it. Depending on how strict the laws are in the state you are in, you can get away with several violations before it becomes an issue. But, there are no guarantees. Play it safe by following the law and getting your tint done professionally.

Exceptions for Window Tinting Rules

While the vast majority of the time, exceptions to the basic window tinting rules in California are rare, there is an exception for people with a special permit. For those with a prescription eligible to receive tinted windows, the rules and regulations are relaxed a little. For those with certain medical conditions who qualify, darker tint on side and rear windows may be permitted, subject to certain special conditions. In order to qualify, a certificate from a licensed physician or surgeon, stating that the individual is under visual care of the doctor and suffers from a condition which requires special window accommodations for therapies such as phototherapy or the treatment of skin conditions , must be provided to the California Department of Motor Vehicles to obtain an exemption sticker. Once the exemption sticker is obtained, it must be placed on the vehicle, at a specified location, pursuant to California Vehicle Code Section 26708(e)(1). However, the darker tint may only be installed on the left and right side windows and rear windows, not the front windshield, in order for the tinted windows to be legal. Phototherapy often calls for exposure to ultraviolet light units, such as tanning beds, in order to treat skin disorders such as psoriasis and vitiligo while allowing some ultraviolet light penetration necessary for the normal health maintenance of the body. Phototherapy also stimulates the immune system to help provide a general health boost that other therapies might not help with.

How to Ensure You Are Compliant

To ensure compliance with California’s window tint law, vehicle owners should take certain precautions. First, it’s a good idea to consult with a reputed professional window tinting service that is well-versed in the legal limits and requirements. These professionals can provide guidance on the appropriate tint levels for each window, as well as any additional requirements for accessories such as sun strips or rear-view mirror tinting. Second, when seeking the services of a professional window tint installer, verify that they use only high-quality films that come with a warranty. Also, make sure that the tint installation process is compliant with all regulations, including proper measurements and installation techniques. If unsure about whether your vehicle’s window tint measures within legal limits, you can obtain a tint meter to measure the percentage of light transmission through your window film. A simpler method of testing is to place a roll of clear tape against the film to see if any light passes through when you hold a 60-watt light bulb 12 inches away. If the tape appears black, your tint is too dark.

Future Changes for Car Window Tint

As is the case in every state, new laws are frequently introduced in California. In recent years, bills have been pre-filed by legislators that would ease some of the restrictions on window tinting in the state. However, none of the bills have been taken up in committee and pushed further forward at this time. As the politically environment is constantly shifting , anything could happen in the future. It is possible that the window tinting laws will be modified in the state to allow for darker film or additional forenoon or side windows. However, as it stands right now, the most stringent window tinting laws in the country are also in effect in California. Because window tinting is not a necessity, the legislature may be hesitant to make these changes.
