Montana Window Tint Laws Explained: What Bozeman Drivers Need to Know
If you’re considering window tint for your car, truck, or SUV in Bozeman, there’s one thing you need to be absolutely sure of before making the investment — is your tint legal in Montana?
Every state sets its own window tinting regulations, and here in Montana, the law is specific about how dark or reflective your tint can be. If your goal is added privacy, better UV protection, or reduced glare from snowy winter roads, understanding the rules will help you avoid costly tickets and get the most from your upgrade.
This guide breaks down Montana’s window tint laws in simple terms so you can choose the perfect shade without crossing the line.
Why Montana Regulates Window Tint
Window tint laws are designed to balance two main factors:
Driver safety — ensuring enough visibility for safe driving, especially at night or during poor weather conditions.
Law enforcement visibility — allowing police to see into vehicles during traffic stops for safety purposes.
At Montana’s high elevations, tint is especially popular because it blocks harmful UV rays and reduces glare from the intense sunlight reflecting off snow, water, or bright pavement. But even with these benefits, it’s important to stay within the legal limits.
Montana Window Tint Requirements by Vehicle Type
Montana’s tint laws differ slightly depending on whether you drive a passenger car or an SUV/truck.
Passenger Cars
Windshield: Non-reflective tint allowed above the manufacturer’s AS-1 line.
Front Side Windows: Must allow at least 24% of light in (24% VLT or higher).
Back Side Windows: Any darkness can be used.
Rear Window: Any darkness can be used.
SUVs and Trucks
Windshield: Non-reflective tint allowed above the manufacturer’s AS-1 line.
Front Side Windows: Must allow at least 24% of light in.
Back Side Windows: Any darkness can be used.
Rear Window: Any darkness can be used.
What is VLT and Why Does It Matter?
VLT stands for Visible Light Transmission, and it measures how much visible light passes through your tinted windows. A higher VLT number means lighter tint (more light passing through), while a lower VLT number means darker tint (less light passing through).
In Montana, the key number to remember for front side windows is 24% VLT — anything darker can put you at risk of a ticket.
If your vehicle’s tint doesn’t meet Montana’s requirements, you can be ticketed and fined. In some cases, you may be required to remove or replace the tint to meet legal standards.
Fines can vary depending on the county, but avoiding the hassle entirely is as simple as working with a professional tint installer who understands local laws — like our team here in Bozeman.
Why Professional Installation is Worth It
DIY tint kits might seem cheaper, but they often don’t meet legal standards or last as long. A professional installer ensures:
Correct VLT percentages for Montana law
High-quality film that won’t bubble, peel, or fade
Clean, precise application for a flawless finish
Documentation to prove your tint is compliant
