Window Tint laws in Montana
In Montana, the law concerning vehicle window tint is detailed in Montana Code Annotated (MCA) 61-9-408. This statute generally prohibits the use of tinting material on the windshield that reduces light transmission to less than 70% in the area above the AS-1 line or top 5 inches, whichever is greater. For side windows to the immediate right and left of the driver, and all windows behind the driver, the tint must allow at least 24% of light to pass through. Reflective tinting is also regulated, with a maximum reflection of 20% on all windows. There are specific considerations for medical exemptions. Individuals with a medical condition exacerbated by sunlight may apply for a medical exemption to use darker tint, provided they carry a physician's certificate. Additionally, certain vehicles like limousines, buses, and law enforcement vehicles may have different tinting allowances. Non-compliance can lead to citations, requiring the vehicle owner to remove the non-compliant tint.
