Understanding the Terminology Regarding Tint Laws
The most important part of the legislation is understanding what VLT is and how law enforcement services check or test the percentage.
What is VLT
VLT, or Visible Light Transmission, is a measure of the amount of visible light that can pass through a window tint or film. It is commonly used to determine the darkness or opacity of window tints, and it’s an important factor in window tinting laws and regulations.
VLT is typically expressed as a percentage. For example, a window tint with a VLT of 20% allows only 20% of visible light to pass through, making it relatively dark and less transparent. Conversely, a window tint with a VLT of 70% allows 70% of visible light to pass through and is much lighter and more transparent.
How do Law Enforcement services test the VLT percentage?
Window tinting laws vary by jurisdiction, and they often specify the maximum allowable VLT for different types of windows on a vehicle, such as the front windshield, front side windows, rear side windows, and rear window. These laws are designed to ensure that drivers have adequate visibility and that law enforcement can see into vehicles for safety and identification purposes. The manner that they go about testing the VLT is by using a VLT gauge/meter.
Here is a YouTube Short from @TrafficServices and @TorontoPolice showcasing the device and how it works. Even though it is in Canada, it still is helpful to understand how the tint darkness is measured.
Window Tint Darkness in California:
In California, the degree of visible light allowed through your vehicle’s windows is quantified using the term VLT, or Visible Light Transmission. The VLT requirements differ for sedan cars and SUVs or vans. Here’s the breakdown:
California Car Tint Laws For Sedans:
- Windshield: The law allows non-reflective tint solely on the top 4 inches of the windshield.
- Front Side Windows: Aftermarket window film must permit more than 88% of light to pass through. Alternatively, a minimum of 70% VLT is acceptable if combined with factory-tinted windows.
- Back Side Windows: California law does not prescribe any specific darkness for the back side windows, providing flexibility in this regard.
- Rear Window: Similar to back side windows, there are no restrictions on the darkness of the rear window.
Tint Laws For SUVs and Vans in California:
- Windshield: SUVs and vans are held to the same standards as sedans, allowing non-reflective tint on the top 4 inches of the windshield.
- Front Side Windows: As with sedans, aftermarket window film for SUVs and vans must permit more than 88% of light transmission. Alternatively, a minimum of 70% VLT is acceptable when combined with factory-tinted windows.
- Back Side Windows: California’s law for SUVs and vans also does not stipulate any specific darkness for the back side windows.
- Rear Window: SUVs and vans have the same liberty as sedans, allowing any level of darkness on the rear window.
| Type of Window | Sedans | SUVs/Vans |
|---|---|---|
| Windshield | Non-reflective tint allowed on the top 4 inches | Non-reflective tint allowed on the top 4 inches |
| Front Side Windows | Aftermarket film: >88% light transmission or 70% VLT with factory tint | Aftermarket film: >88% light transmission or 70% VLT with factory tint |
| Back Side Windows | No specific darkness requirement | No specific darkness requirement |
| Rear Window | No specific darkness requirement | Any level of darkness allowed |
Window Tint Reflection in California:
Window tints can reflect incoming light, which can aid in reducing glare and heat. In California, the law permits a specific degree of window reflection, and this should be considered carefully.
Reflectivity Tint Laws For both Sedans and SUVs/Vans:
- Front Side Windows: Reflectivity on front side windows must not exceed that of a standard window.
- Back Side Windows: Back side windows, too, must not be more reflective than a standard window.
Additional California Window Tint Rules and Regulations:
California’s window tinting laws encompass several other noteworthy regulations:
Side Mirrors
If the rear window is tinted, dual side mirrors are required, enhancing safety measures.
Restricted Colors
California’s tint laws disallow the use of red, amber, or blue tint colors. Side windows must remain colorless.
Certificates
Film manufacturers are obligated to certify the film they sell within the state, and the driver is required to possess the certificate.
Stickers
State law mandates the presence of a certificate or a sticker from the installing company, bearing the manufacturer’s name and address.
Medical Exceptions
Notably, California’s law allows for medical exemptions, permitting a lower tint on all windows for individuals with specific medical needs.
Regulations for Out-of-State Drivers
The same regulations apply to out-of-state drivers as those for drivers living in the State.
If you are from states such as Arizona, Nevada, and Oregon, you are expected to abide by these laws and regulations.
