In Utah, the law allows for non-reflective window tint on the windshield above the AS-1 line (4 inches down from the top of the windshield) and on windows behind the driver. The tint on the front side windows must allow at least 43% of light to pass through, while there is no restriction on the amount of tint on the rear side and back windows. Reflective tint is not allowed on any windows, except for medical exemption.
Additionally, medical exemptions for tinted windows are allowed with a written prescription from a licensed physician, stating the condition that requires the exemption. The vehicle must also display a certificate of exemption on the front windshield.
Drivers who violate Utah’s auto window tint law could face a fine starting at $130.
