Understanding Colorado Window Tint Law Basics

Before we get into the details, let us talk about the basics. Colorado window tint law is all about light transmission. The key term you will hear over and over is Visible Light Transmission, or VLT. VLT measures how much light your tint lets through. The lower the VLT percentage, the darker the tint. A 5% VLT tint is very dark. A 70% VLT tint is barely tinted at all.

Colorado law sets different VLT limits depending on which window you are tinting. The front windshield has its own rules. The front side windows have their own limits too. And the rear windows? They are a different story entirely. Let us break this down window by window so it is crystal clear.

What Is VLT and Why Does It Matter?

Visible Light Transmission is the percentage of light that passes through your window film. Think of it like sunglasses for your car. The darker the lens, the less light gets through. Colorado law cares about this because visibility matters. The state wants drivers to see clearly, especially at night and in bad weather. If your tint is too dark, it can be dangerous. That is why the law sets minimum VLT levels for certain windows.

When you buy car window film, the seller should tell you the VLT percentage. Make sure you know this number before you install it. If you are unsure, ask the installer. A reputable tint installation shop will always be upfront about the VLT of their products. And keep in mind that the VLT of your window includes both the film and the original glass. So a tint with a 27% VLT rating on a window that already lets in 80% of light will result in a combined VLT that is lower.

Legal Tint Limits for Each Window

Colorado law specifies different tint darkness rules for each window on your vehicle. Let us go through them one by one. This is where the Colorado Window Tint Law Guide really becomes useful.

Front Windshield Tint Rules

The front windshield is the most regulated window. In Colorado, you can apply a non-reflective tint to the top 4 inches of your windshield. That is it. No exceptions for the rest of the windshield. The reason is simple. Your windshield gives you a clear view of the road ahead. Blocking too much light can create dangerous blind spots. The 4-inch strip, often called the sun strip or visor strip, helps reduce glare from the sun without blocking your view.

Here is what is allowed and not allowed for your front windshield:

• Allowed: Non-reflective tint on the top 4 inches only
• Not Allowed: Any tint below the 4-inch mark
• Not Allowed: Reflective or mirrored finish on any part of the windshield

Front Side Window Tint Rules

The front side windows on both the driver and passenger sides must allow more than 27% of light to pass through. This means your tint darkness on these windows needs to be relatively light. You can still tint them, but the tint cannot be too dark. This rule applies to sedans, SUVs, and vans alike.

Why 27%? Colorado law strikes a balance between style and safety. The 27% tint percentage allows you to enjoy some benefits of window film while still maintaining good visibility from the driver’s seat. It also ensures that law enforcement can see inside your vehicle during traffic stops, which is important for everyone’s safety.

Rear Side Window Tint Rules

Here is some good news. The rear side windows on your vehicle have no darkness restriction in Colorado. You can tint them as dark as you want. Whether you want a light tint or a nearly black finish, the law does not limit you on these windows. This applies to both sedans and SUVs.

However, there is one catch. If your rear side windows are tinted darker than 27% VLT, your vehicle must have dual side mirrors. The idea is that if you cannot see out of the rear windows, you need mirrors to compensate. This ensures you still have adequate visibility when changing lanes or merging.

Rear Window Tint Rules

Just like the rear side windows, the rear window can be tinted to any darkness you prefer. No VLT limit applies. You can go with a dark factory-style tint or something lighter. The same dual mirror rule applies here too. If your rear window is heavily tinted, make sure you have working side mirrors that give you a clear view of the road behind you.

Tint Reflectivity Rules in Colorado

It is not just about how dark your tint is. Colorado also has rules about how reflective your tint can be. Reflective tint, sometimes called mirror finish or metallic tint, bounces light away from the car. While it looks cool, it can blind other drivers. That is why Colorado restricts it.

Front Side Window Reflectivity

Reflective or mirrored tint is not allowed on the front side windows. The tint on these windows must be non-reflective. This means no shiny, mirror-like finish on your driver or passenger side windows. The goal is to prevent glare and ensure that other drivers can see through your windows when light hits them.

Rear Window and Rear Side Window Reflectivity

There are no specific reflectivity restrictions on the rear side windows or rear window in Colorado. You can use reflective tint on these windows if you choose. However, keep in mind that highly reflective rear windows can sometimes cause issues with rear visibility for the driver. So even though the law allows it, use common sense and make sure your driving visibility is not compromised.

Tint Colors and Special Restrictions

Colorado law does not specifically ban any tint colors. You can choose from a range of tint shades including charcoal, gray, bronze, and even blue. However, there are some general guidelines you should follow. The tint should not be so dark or colored that it significantly impairs visibility. And as we mentioned, reflective finishes are restricted on front side windows.

Aftermarket Tint vs. Factory Tint

It is important to understand the difference between aftermarket tint and factory tint. Factory tint comes built into the glass when the car is manufactured. It usually has a VLT of around 75% to 80%. Aftermarket tint is the film you apply after purchasing the vehicle. Colorado law measures the combined VLT of both the factory tint and any aftermarket film you add. So if your car already has a factory tint of 80% VLT, and you add a film that is 50% VLT, the combined result might be around 40% VLT. You need to make sure the final combined VLT meets the legal requirements for each window.

Medical Exemption for Darker Tint

Not everyone can tolerate regular tint darkness levels. Some people have medical conditions that make them extremely sensitive to sunlight. For these individuals, Colorado offers a medical exemption for darker window tint. This exemption allows you to tint your windows darker than the standard legal limits.

Who Qualifies for a Medical Exemption?

Several medical conditions may qualify you for a tint exemption in Colorado. These include:

• Lupus: Patients with lupus often experience severe photosensitivity. Even small amounts of UV exposure can trigger symptoms.
• Albinism: People with albinism lack melanin, making them extremely sensitive to sunlight.
• Solar urticaria: This is a rare condition where sunlight causes allergic reactions on the skin.
• Photosensitive epilepsy: Bright light can trigger seizures in some individuals.
• Severe eczema or dermatitis: Sun exposure can worsen symptoms for some skin conditions.

How to Apply for an Exemption

To get a medical exemption for window tint in Colorado, you need a signed statement from your licensed physician. This statement must explain your condition and why darker tint is medically necessary. You should carry this document in your vehicle at all times. If you are pulled over, you can show the exemption to the officer. The exemption does not exempt you from all tint rules. It simply allows darker tint than the standard legal limits for the specific windows listed in the physician’s statement.

Tint Stickers and Documentation Requirements

Colorado law requires that you display a tint sticker on your vehicle. This sticker certifies that your window tint is legal. It should be placed on the driver’s side window, typically in the lower corner where it is visible but does not obstruct your view. The sticker serves as proof that your tint complies with Colorado regulations.

Keep your tint installation receipt and any documentation from your tint installer as well. If you ever need to prove that your tint meets legal standards, these documents can help. A reputable tint shop will provide you with a certificate or sticker at the time of installation.

Penalties for Illegal Window Tint

What happens if you get caught with illegal tint in Colorado? The consequences are not fun. Let us look at what you might face.

Tint Tickets and Fines

A tint ticket in Colorado can cost you anywhere from $50 to $500 depending on the severity of the violation and your county. This is a fine you can avoid easily by making sure your tint is legal before you install it. If you get a ticket for illegal tint, you will typically have to pay the fine and may be required to remove the tint within a certain timeframe.

Vehicle Inspection Issues

Colorado requires vehicles to pass an annual inspection. Illegal tint can cause your vehicle to fail the inspection. This means you cannot register your car or renew your plates until the tint is brought into compliance. Removing and re-tinting your windows costs both time and money. It is much easier to just follow the law from the start.

Repeated Violations

If you get multiple tint violation tickets, the fines can add up quickly. Some counties may also impound your vehicle if you have repeated violations. Avoid this hassle by staying informed about the law and choosing your window film wisely.

Quick Tips for Staying Compliant with Colorado Window Tint Law

Staying on the right side of the law is easy when you follow a few simple tips. Here are some practical suggestions to keep in mind:

• Choose a reputable tint shop: A professional tint installer will know the Colorado regulations and help you pick the right film.
• Ask for the VLT percentage: Always confirm the VLT of the film before installation. Make sure it meets the legal requirements.
• Get a tint sticker: Make sure your installer provides the required legal tint sticker for your driver’s side window.
• Keep your documents handy: Save your tint receipt and any exemption certificates in your glove box.
• Consider factory tint: If your car already has factory tint, factor that into your decision when choosing aftermarket film.
• Double-check local county rules: While Colorado state law sets the baseline, some counties may have additional regulations. Check with your local DMV if you are unsure.

Benefits of Legal Window Tint in Colorado

Now that you know the rules, let us talk about why window tint is worth it in the first place. Colorado gets a lot of sunshine. In fact, the state averages over 300 days of sunshine per year. That is a lot of UV exposure for you and your car.

UV protection is one of the biggest benefits of quality window film. Harmful UV rays can cause skin damage and increase your risk of skin cancer. They also fade your dashboard, seats, and interior over time. A good tint blocks up to 99% of UV rays, protecting both you and your vehicle.

Heat rejection is another major advantage. Tinted windows can reduce the interior temperature of your car by up to 30 degrees Fahrenheit. That means less reliance on your air conditioning, which improves fuel efficiency. On those hot summer days in Denver or Colorado Springs, a cooler car is a welcome relief.

Glare reduction makes driving safer, especially during Colorado’s bright winter days when sunlight reflects off snow. Tinted windows cut down on glare from the sun and from headlights of oncoming traffic at night. This reduces eye strain and helps you stay focused on the road.

Privacy and security round out the benefits. Tinted windows make it harder for people to see into your vehicle. This protects your valuables from prying eyes and can deter break-ins. Whether you are parking at a trailhead or a shopping mall, tinted windows give you peace of mind.

Common Mistakes People Make with Window Tint in Colorado

Even well-meaning car owners make mistakes when it comes to window tint. Here are some of the most common ones:

• Buying tint without checking VLT: Many people buy the darkest tint they can find without checking if it is legal for their front side windows. Always verify the VLT before you buy.
• Ignoring factory tint: If your car already has factory tint, adding aftermarket film can push the combined VLT below the legal limit. Always account for existing tint.
• Skipping the sticker: Forgetting to display the legal tint sticker can result in a citation even if your tint is within limits.
• Using bubble-gum DIY kits: Cheap DIY tint kits often have inconsistent VLT and can bubble or peel quickly. Professional installation ensures compliance and longevity.
• Assuming all states have the same rules: If you recently moved to Colorado from another state, your tint may not be legal here. Always check Colorado-specific regulations.

Expert Insights on Colorado Window Tint Law

We spoke with several Colorado auto care professionals to get their take on window tint law compliance. Here is what they had to say.

“The most common mistake we see is people tinting their front side windows too dark,” says Jake Morrison, a veteran tint installer in Denver. “They want that dark, sleek look, but the 27% VLT limit is firm. We always recommend a 35% VLT film for the front sides. It looks great and keeps you completely legal.”

“The medical exemption process is straightforward, but many people do not know it exists,” adds Sarah Lin, a Denver-based auto attorney. “If you have a condition that makes you sensitive to sunlight, talk to your doctor about an exemption. It can save you a lot of hassle.”

“Colorado’s sunshine is both a blessing and a curse,” notes Dr. Tom Rourke, a dermatologist in Colorado Springs. “Window tint is one of the best ways to protect your skin from UV damage during your daily commute. Just make sure your tint complies with state law.”

How to Choose the Right Tint for Your Vehicle in Colorado

Choosing the right window film for your car involves more than just picking a shade you like. You need to consider legal limits, your driving needs, and the quality of the film. Here is a step-by-step approach.

First, check your vehicle’s current VLT. You can measure this with a VLT meter available at most tint shops. This tells you how much light your windows already let in. Then, decide which windows you want to tint and what VLT you want for each.

Next, research different types of window film. Dyed film is the most affordable but fades over time. Metalized film offers better heat rejection but can interfere with electronic signals. Ceramic film is the premium option. It provides excellent UV and heat protection without interfering with electronics. It is also the most expensive. Carbon film is a great middle ground. It offers good heat rejection, does not fade, and has a matte finish that many people prefer.

Finally, choose a licensed and experienced tint installer in Colorado. Look for reviews, ask about warranties, and confirm they understand Colorado tint regulations. A good installer will guide you through the process and make sure your tint is both legal and beautiful.
