Yes, you can tint your car windows in Missouri, but you must follow the state’s specific rules. Understanding the car window tint laws in Missouri is key to staying legal and avoiding fines.
These rules tell you how dark your tint can be and how much light it must let through. They cover all windows on your car, truck, or SUV. The rules are there for safety, so police can see inside your vehicle if needed.
If you break these rules, you could get a ticket. You might also have to remove the tint, which costs more money. It’s smart to know the law before you get any tint put on your windows.
What Are the Car Window Tint Laws in Missouri?
Let’s break down the main rules for car window tint laws in Missouri. The law uses a term called VLT, which means Visible Light Transmission.
VLT is the percent of light that gets through your window film and glass. A lower VLT number means a darker tint. A higher VLT number means a lighter tint that lets more light in.
For the front side windows, the car window tint laws in Missouri say they must let in at least 35% of light. So, you need a 35% VLT tint or higher. This rule makes sure drivers can see out clearly, especially at night.
The back side windows and the rear window can be much darker. The car window tint laws in Missouri allow any darkness for these windows. This gives you more privacy in the back of your vehicle.
Your windshield can only have a tint strip along the top. This strip can’t go down more than five inches from the top of the glass. The rest of your windshield must stay clear.
These are the basic rules for most passenger cars and trucks. Always check the latest rules from the Missouri Department of Transportation to be sure.
Why Do Car Window Tint Laws in Missouri Exist?
You might wonder why the state makes these rules. The car window tint laws in Missouri are not just to be difficult.
First, they help with safety for police officers. If an officer walks up to your car, they need to see inside. They need to see your hands and how many people are in the car.
Second, the rules help you see other cars and people on the road. Tint that is too dark can make night driving hard. It can be tough to see pedestrians, bikes, or animals.
Third, the car window tint laws in Missouri help with traffic stops. Clear windows make these stops safer for everyone involved. It reduces surprises for the officer.
These laws also set a standard for everyone. They make sure all tint shops in the state follow the same guidelines. This keeps things fair for drivers and businesses.
In short, the car window tint laws in Missouri balance your want for privacy with the need for public safety on the roads.
How to Measure Your Tint for Missouri Laws
To follow the car window tint laws in Missouri, you need to know your tint’s VLT. You can’t just guess if it looks legal.
A professional tint shop will have a tool called a tint meter. They can test your windows to give you the exact VLT percentage. This is the best way to know for sure.
If you are buying a used car with tint, you should get it checked. The previous owner might have put on illegal tint. You are responsible for it once you own the car.
Remember, the car window tint laws in Missouri measure the combined VLT. This means the meter reads the light through both the factory glass and the added film. Factory glass already blocks some light.
So, if you add a 50% VLT film to glass that already blocks 20% light, your final VLT might be only 40%. A good tint shop will do this math for you. They will suggest film that gets you to the legal 35% VLT or higher for your front windows.
You can find more on safety standards from the National Highway Traffic Safety Administration. They talk about driver visibility and window tint.
Medical Exceptions to Car Window Tint Laws in Missouri
The car window tint laws in Missouri do allow for medical exemptions. Some people need darker tint for a health reason.
For example, a person might have a skin condition that makes them very sensitive to sunlight. Or they might have an eye condition that requires less bright light.
To get this exemption, you need a signed statement from a doctor. The doctor must be licensed in Missouri. The statement must say you have a condition that needs darker car windows.
You must keep this statement in your vehicle at all times. You need to show it to a law enforcement officer if they ask about your tint.
With this exemption, you can have darker tint than the standard car window tint laws in Missouri allow. But the state still sets a limit. Your front side windows can go as dark as 20% VLT with a medical note.
It’s important to get the right paperwork. The Missouri Department of Revenue handles vehicle registrations and can provide details on the exemption process.
Consequences of Breaking Car Window Tint Laws in Missouri
What happens if you don’t follow the car window tint laws in Missouri? The penalties can be a real hassle.
First, you will likely get a ticket. This is a fine you have to pay. The cost varies by city or county, but it’s money out of your pocket.
The officer might also give you a “fix-it” ticket. This means you have a certain amount of time to remove the illegal tint. You then have to prove to the court that you fixed it.
If you don’t fix it, you could get another ticket. Your car might even fail its safety inspection. In Missouri, some areas require a safety inspection to renew your registration.
Having illegal tint could also cause problems during traffic stops. An officer might be more cautious if they can’t see inside your car. This could make a simple stop take longer.
To avoid all this, just follow the car window tint laws in Missouri from the start. It’s easier and cheaper than dealing with tickets and removal later.
Choosing a Tint Shop in Missouri
When you decide to get tint, picking the right shop is crucial. A good shop will know the car window tint laws in Missouri inside and out.
Ask them directly about the legal VLT for your front windows. They should explain it clearly. They should also guarantee their work meets state law.
A reputable shop will use quality film. Cheap film can turn purple or bubble up after a few years. Good film lasts longer and looks better.
The shop should also give you a certificate or sticker. This often goes on the inside of your door jamb. It shows the film brand and the VLT percentage. This proves to an officer that your tint is meant to be legal.
Check online reviews of the shop. See what other customers say about their experience. Were they happy with the tint job years later?
Remember, the car window tint laws in Missouri are your responsibility. But a good shop makes it easy for you to stay on the right side of the law.
Car Window Tint Laws in Missouri for Different Vehicles
The rules we talked about are for passenger cars. But what about other vehicles? The car window tint laws in Missouri can change a bit.
For multipurpose vehicles like SUVs and vans, the rules are often the same. The front side windows still need 35% VLT or more. The back windows can usually be any darkness.
For trucks, the rules might be different if it’s a commercial vehicle. It’s best to check with the Missouri State Highway Patrol for specific commercial rules.
The car window tint laws in Missouri also have rules about reflective tint. Your tint cannot be too mirror-like. Reflective tint can distract other drivers by glaring sunlight into their eyes.
The law says side windows cannot be more than 35% reflective. This is another thing a good tint shop will know. They won’t install film that is too shiny.
Always confirm the exact rules for your specific type of vehicle before you get tint installed. A quick call to the Missouri State Highway Patrol can clear up any confusion.
Maintaining Your Tint and Staying Legal
Once you have legal tint, you want to keep it that way. Taking care of your tint helps it last and keeps you within the car window tint laws in Missouri.
When you clean your windows, use a soft cloth and ammonia-free cleaner. Ammonia can break down the tint film and make it fade or bubble.
Don’t roll down your windows for a few days after the tint is installed. The film needs time to dry and stick to the glass properly. Your shop will tell you how long to wait.
Over time, even good tint can fade a little. If it fades a lot, it might change the VLT. A very faded tint might technically become illegal if it gets too dark from color change.
If you get a ticket and think your tint is legal, you can contest it. You would need proof, like the certificate from your tint shop. You might also need a current tint meter reading from a shop.
Following the car window tint laws in Missouri is an ongoing thing. It’s not just about the day you get the tint put on. You need to make sure it stays legal for as long as you have it.
