Idaho’s window tinting laws primarily revolve around the permissible levels of visible light transmission (VLT) and the level of reflectivity for different windows on a vehicle. These limits are designed to balance the driver’s need for privacy, sun protection, and aesthetics with the safety concerns of law enforcement officers and other drivers.

What Does VLT Mean According to Idaho State Law?

VLT stands for Visible Light Transmission. In the context of Idaho state law and window tinting, VLT refers to the amount of visible light that is allowed to pass through the window after tinting. For example, if the law requires a VLT of 35% for front side windows, it means that the window must allow at least 35% of visible light to pass through while blocking the rest. This measurement is important in ensuring driver visibility and compliance with the state’s tinting regulations.


Understanding and adhering to Idaho’s window tinting laws is essential for all vehicle owners, whether they are Idaho residents or visitors passing through the state. By complying with these regulations, drivers contribute to safer road conditions and the overall harmony between aesthetics, comfort, and safety. Staying informed about the permissible VLT and reflectivity levels, as well as the potential for medical exemptions, empowers individuals to make informed decisions about their window tinting choices while ensuring that they remain within the bounds of the law.
