Missouri Window Tint Laws

Missouri Window Tint Laws
The state of Missouri first enacted vehicle window tint laws in the year 2002 and the same laws passed then are still in place and largely unchanged. But as the auto window film market has developed and changed in myriad ways since then, it’s important that you take care to use window tints that are still within the purview of Missouri tint laws given that many window film products now in use were not even available some two decades back.
The latest car window tint advancements include products like nanoceramic window film, a nonmetallic window tint wherein hundreds of thousands of microscopic ceramic bits are infused into thin but amazingly strong sheets of film.
Nanoceramic window film can block up to 50% (or more with some products) of the sun’s hot infrared light, keeping a car cooler and more comfortable, and this and other window tints can reject more than 99% of the sun’s damaging UV light, stopping interior fading and cracking and thus preserving your car’s value and also protecting your eyes and skin from sun damage.
Car window tint also stops the harsh glare of sunlight from making driving less safe, thus protecting you and your passengers and your fellow motorists. And then of course there is the privacy and style window tint can add to your car.
Despite all the many benefits of car window tinting, it is the darkness of the tint that authorities tend to focus on, with darkness being rated by the visible light transmission, or VLT, percentage of the tint. Thus we will break down Missouri VLT restrictions in detail so you can make sure your auto window tint is legal in the state and be sure you are enjoying all the benefits of auto window tint without risking a window tint ticket in Missouri, a violation that can cost $75 per infraction.
Visible light transmission simply refers to the amount of light a tinted window lets pass through, and the higher the number, the less tint is present and the more transparent the window. A 100% VLT pane of glass is fully transparent, therefore, while 50% VLT blocks half of the sun’s visible light. The lower the VLT, the harder it is to see through the window and the more privacy the tint adds.

% of Tint or Visible light transmission (VLT) is the measurement used to assess the amount of light passing through a piece of glass. This is the percent of visible light that passes through the film and glass to give you a net transmission percentage. The lower the VLT%, the darker the window.
Law Enforcement uses a tint meter which measures the Visible Light Transmittance (VLT) of window film and glass for illegal tint.
Windshield: Several states allow medical exemptions for drivers or passengers who frequently travel in the vehicle. These exemptions usually require a licensed physician in that state to sign a waiver. Please visit your states .gov site for details.

If you’re driving a truck or SUV built in the last decade, chances are it’s equipped with factory tinted glass on all windows behind the front doors.
Many owners of vehicles like this often choose to only have the front windows tinted to match the back because they believe that they are already set with the rear windows.
UV Protection
While this factory tint improves the looks of the vehicle, and offers rear passengers some privacy, it does very little to help reduce the heat entering through the glass or protect them from the sun’s harmful UV rays.
Heat Rejection
The same also goes for heat rejection. Some assume that the level of heat rejection they will on the front glass is already present in the rear glass because of the factory tint. Nothing can be further from the truth. Other than having the tinted look, these windows do very little to stop the heat.
