What is the Darkest Legal Tint in Los Angeles?


Tinted windows for cars are very popular in Los Angeles. They offer benefits like increased privacy, reduced glare, and protection from harmful ultraviolet rays. To avoid fines and to ensure road safety, it is important to follow local regulations for window tinting. This blog will provide you with information about the tinting laws in California and the darkest tint that is legal.

Understanding Window Tinting

Window tinting is the process of applying a thin, opaque film to either the interior or exterior windows of a car. Visible Light Transmission (VLT), a percentage, can be used to measure the darkness of a film. VLT is the amount of visible sunlight that passes through a window. A lower VLT percentage indicates a darker tint while a higher percentage shows a lighter tint.

California Tint Laws

California has specific window tinting regulations that apply to the entire state, including Los Angeles. These laws aim to improve visibility and safety for drivers, vehicle occupants and road users. California’s window-tinting laws include:

Windshield Tinting

Only the top four inches of your windshield can be tinted with a non-reflective strip. This strip, also known as an “eyebrow”, or “sun-strip”, helps reduce the glare of the sun.

Front Side Windows

– Must let more than 70% light through. The tinting on the side windows of the vehicle can be very light as long as the driver can see clearly.

Rear Side Windows & Back Window

– Any darkness is allowed. The rear side and back windows are not subject to VLT restrictions, allowing vehicle owners greater flexibility when choosing the shade of tint for these areas.

Reflective Tint

California law addresses reflectivity as well as VLT regulations. Reflective tints reduce heat and glare, but too much reflectivity can be a safety hazard because it can shine into other drivers’ eyeballs. Here are the rules:

Front Side Windows and Rear Side Windows

The tint cannot be more reflective than the standard window. It should not be a mirror finish, and it should reflect light similarly to standard factory installed windows.

Medical Exemptions

California offers medical exemptions to the window tinting law. A driver or passenger with a medical condition requiring additional protection from sunlight can apply for a special exemption. A letter or prescription detailing the need for special window tinting is required. The front side windows may be tinted darker than the standard limit of 70% VLT.

Penalties if You Don’t Comply

California window tinting law can lead to fines, and even the need to remove or modify illegal tint. The devices that law enforcement officers use to measure VLT are readily available, allowing them to easily enforce this regulation. To avoid penalties and maintain safe driving conditions, it’s important to stick to the legal limit.


Los Angeles’ darkest tint for front side windows must allow more than 70% light through. Any darkness is permitted for the rear side window and back window. It is important to understand and adhere to these regulations in order to avoid penalties and ensure safety on the roads. Choose the correct window tint to meet your needs, whether it’s for privacy, UV protection or style.
