There’s no doubt that cars with tinted windows look cool, but do you know the Montana window tint law? If you have tinted windows or plan to get your car windows tinted, you are in the right place. We’ve gathered all the legal information you need to know about Montana tint laws.


First, Let me Explain What VLT Means?

VLT Visible Light Transmission is the percent of visible light that gets through your car windows. In other words, the lower the VLT%, the darker the tint gets. For example, 5 % would be a very dark tint. Furthermore, the state of Montana has the following VLT%, as you can see below.

Benefits of  Window Tinting

Window tinting blocks up to 99% of the UV rays. The car interior cools by 60%. It also can help protect from ultraviolet radiation and help protect your car’s interior from cracking or fading and looking worn-out. Another great benefit is the level of privacy, which can prevent someone who walks by to peer inside.

Car Window Tint Cost

In general, the cost may vary; for example, a basic tint for a sedan car using the classic film can cost less than $150 per vehicle. However, suppose you want a top-quality film such as ceramic window tint. In that case, it can cost up to $400 per vehicle. Of course, all depend on different factors (number of windows, type of tint, warranty). On the other hand, a cheaper option for professional tinting services is a DIY tint kit, which usually costs less than $100.








Note: Keep in mind that Montana tint laws can change daily and be interpreted differently in your city or county. To be sure, we recommend double-checking our information with your local DMV or Law Enforcement Authorities. Furthermore, please let us know if there are any further changes to be made.
