Window Tint laws in Missouri

Missouri law dictates specific Visible Light Transmittance (VLT) percentages for vehicle window tinting. For the front side windows (those next to the driver and front passenger), the tint must allow more than 35% VLT. For the back side windows and the rear window, the tint must allow more than 35% VLT. Tinting is not allowed on the windshield below the AS-1 line or more than 5 inches from the top of the windshield, whichever is less. Violations of these tinting regulations can result in fines. The statutes governing window tinting in Missouri are primarily found in Missouri Revised Statutes (RSMo) Section 307.170. This statute outlines equipment requirements and safety glazing materials. Owners of vehicles with illegal tint may be pulled over and cited. There are some exceptions to these rules. Vehicles used for specific purposes, such as law enforcement, or those with medical exemptions may have different tinting allowances. Owners seeking a medical exemption must obtain a physician's statement verifying that tinted windows are medically necessary due to a condition that makes them unduly sensitive to light. This statement must be carried in the vehicle at all times. Failure to comply with these restrictions can lead to a fine and the requirement to remove the non-compliant tint. It is important to note that the 35% VLT refers to the amount of light that can pass through the combined effect of the film and the factory glass. Most factory glass already has a slight tint, so a film advertised as 35% VLT might result in a lower overall VLT when applied to the car's windows.
