Are Tinted Vehicle Windows Legal in Montana?

If you love the look and privacy that tinted windows give your ride, you might be wondering: Is it actually legal in Montana? Let’s break down the basics so you know what’s allowed and what could get you a ticket.

Montana’s Tint Rules Vary by Window

Not all windows on your vehicle have the same tinting rules. Montana law looks at the front windshield, front side windows, rear side windows, and the back window separately. The restrictions depend on which window you’re tinting.

What About the Front Windshield?

When it comes to the front windshield, Montana is pretty strict. You can only have tint on the top few inches, specifically, a strip along the top (called the AS-1 line) is allowed. Beyond that, the law requires the windshield to be clear so you have full visibility.

Front Side Windows Have Limits, Too

For the front driver and passenger windows, Montana law says the tint must let in at least 35% of outside light. That means darker tints that block more light are not legal here on those windows.

Rear Windows Are More Flexible

The rules relax a bit for the rear side windows and the back window. You can have a much darker tint on those windows, which is great for privacy or sun protection. Just remember, if your rear windows are tinted, your vehicle must have side mirrors on both sides to ensure you can see behind you safely.

Medical Exceptions Are Possible

If you have a medical condition that requires extra protection from sunlight, Montana allows you to apply for a medical exemption to use darker tints on your windows. You’ll need a doctor’s note and an official permit, so check with the Montana Motor Vehicle Division if this applies to you.

Why Do These Rules Matter?

Window tinting laws aren’t just about aesthetics. They’re designed to keep drivers safe by ensuring good visibility, especially at night or in bad weather. Plus, law enforcement needs to be able to see inside your vehicle for safety reasons.

What Happens if You Don’t Follow the Rules?

If your window tint is too dark or doesn’t meet Montana’s legal standards, you could get pulled over and cited. Fines and orders to remove the illegal tint are possible, so it’s better to check before you get that super-dark film installed.
