What are the regulations about window tinting in Missouri?
Vehicles registered in Missouri may have the windows to the immediate right and left of the driver tinted to 35%, plus or minus 3% or more light transmittance. Any tint with less light transmittance on these windows would require a physician’s prescription indicating a serious medical condition requiring the darker tinting. Windows behind the driver and the rear glass are not subject to tint limitations. The windshield is not to be tinted except that portion at the top, which is normally tinted by the vehicle manufacturer.
