Understanding California’s Window Tint Laws

California has specific laws and regulations regarding window tinting on vehicles. It is important for drivers in the state to understand these laws to ensure compliance and avoid potential penalties. In this article, we will explore the key points of California’s window tint laws, based on information from reputable sources such as Tinting-laws.com, Fox5SanDiego.com, and AcutintPRO.com.

Windshield Tint

According to California law, non-reflective tint is allowed on the top 4 inches of the windshield. This means that a strip of tint can be applied to the top portion of the windshield, but the remaining area must have sufficient visibility.

Front Side Windows

For front side windows, there are specific requirements for aftermarket tinting films. These films must allow more than 88% of light in, or a minimum of 70% Visible Light Transmission (VLT) if combined with factory-tinted windows. This ensures that front side windows maintain a certain level of transparency for safety reasons.

Back Side Windows and Rear Window

Unlike front side windows, there are no restrictions on the darkness of tint for back side windows and the rear window. Any level of darkness can be used on these windows, allowing drivers more flexibility in choosing the level of privacy and sun protection for these areas.

Rear Windows and Side Mirrors

In California, rear windows can be tinted as long as the vehicle has two side mirrors, excluding the rearview mirror. This requirement is in place to ensure that drivers have sufficient visibility when using tinted rear windows.

Front Window Transparency

Front windows in California must have 70% transparency, meaning they can have up to 30% tint. This requirement ensures that drivers have a clear view of the road and surrounding environment.

Tinting of Front Windshields

Under certain circumstances, front windshields can be tinted in California. However, there is a mathematical formula that must be applied to determine the allowable level of tint. This formula takes into account factors such as light transmittance and reflectance to ensure that the tinted windshield meets the required visibility standards.

Medical Exemptions

While a doctor’s note does not allow permanent tinting of front windows, a temporary shade can be used if it is readily removable. This provision is in place to accommodate individuals with medical conditions that require additional protection from sunlight.

Prohibited Colored Tint

It is important to note that colored tint, such as red, blue, or amber, is illegal in California. The use of these colors for window tinting is not permitted under state law.

Penalties for Non-Compliance

Violators of California’s window tint laws may be issued a fix-it ticket, which requires the driver to correct the tint violation within a specified period. Failure to comply with the fix-it ticket or repeat offenses could result in misdemeanor charges and more severe penalties.

Conclusion



Understanding California’s window tint laws is essential for vehicle owners in the state. By adhering to these regulations, drivers can ensure their own safety and the safety of others on the road. It is important to consult the official California Vehicle Code and verify the latest information from local DMV or law enforcement authorities for any updates or clarifications regarding window tint laws.
