What Is the South Dakota Window Tint Law?

The South Dakota window tint law controls how dark or reflective you can make the windows on your vehicle. These rules are found in the South Dakota Codified Laws, specifically under the vehicle equipment section. The main goal is to ensure driver visibility and safety on the road. Tinted windows can reduce glare and heat, but too much tint can make it hard to see inside your car. That is why the state sets clear limits.

The law focuses on a measurement called Visible Light Transmission, or VLT. VLT tells you what percentage of light can pass through your window film. The lower the VLT percentage, the darker the tint. For example, a 35% VLT means 35% of light gets through, and 65% gets blocked. South Dakota sets different VLT limits depending on which window you are tinting. Let us break those down next.

Why Does VLT Matter?

VLT is the most important number in any tint law. It determines whether your tint is legal or not. Law enforcement officers use specialized tools called tint meters to measure the VLT of your windows during traffic stops. If your tint falls below the legal limit, you could get a ticket. Understanding VLT helps you choose the right film for your vehicle. It also saves you money by avoiding fines and the hassle of having to remove or replace your tint.

Legal Tint Limits for Each Window

South Dakota does not use a one-size-fits-all rule for every window. Instead, the law treats each window differently. Here is a clear breakdown of what is allowed.

Front Windshield Tint Rules

The front windshield has the strictest rules in South Dakota. You are allowed to tint the top 4 inches of the windshield, but only with a non-reflective tint. This strip is often called the sun strip or shade band. The rest of the windshield must remain clear. This rule ensures that the driver has a full view of the road ahead, especially during sunrise and sunset when glare is worst. No tint film of any darkness can be applied below that 4-inch mark on the windshield.

Front Side Window Tint Rules

For sedans and SUVs alike, the front side windows must allow more than 35% of visible light to pass through. This means your tint film must have a VLT of 35% or higher. This rule applies to the driver and passenger side windows. The purpose is to maintain good visibility for the driver and to let law enforcement see inside the vehicle during a traffic stop. If your front side windows are tinted darker than 35% VLT, you are breaking the law.

Rear Side Window Tint Rules

Here is where things get more flexible. In South Dakota, you can tint the rear side windows to any darkness you want. Whether you prefer a light 50% tint or a very dark 5% limo tint, it is legal for rear side windows. However, there is one condition: your vehicle must have dual side mirrors. The mirrors help compensate for the reduced visibility through the tinted rear windows. If your car does not have rearview mirrors on both sides, you should keep the rear windows clear.

Rear Window Tint Rules

The rear window follows the same rules as the rear side windows. You can use any tint darkness you prefer. Again, dual side mirrors are required if the rear window is tinted. This applies to all vehicle types, including sedans, SUVs, vans, and trucks. The law trusts that with proper mirrors, a dark rear window will not create a safety hazard.

Tint Reflection and Color Restrictions

Darkness is not the only factor in the South Dakota window tint law. The state also has rules about how reflective your tint can be. These rules exist because overly reflective windows can blind other drivers, especially at night or in bright sunlight.

Front and Rear Side Window Reflection Limits

Both the front side windows and rear side windows must not be more than 35% reflective. This means the tint film should have a matte or satin finish, not a mirror-like appearance. Metallic and mirrored tint films are generally not allowed on any side windows. If an officer sees a highly reflective window, they can pull you over and issue a citation.

Prohibited Tint Colors

South Dakota does not allow red, amber, or blue tint films on any vehicle window. These colors are typically reserved for emergency vehicles and can confuse other drivers. The law also restricts any tint that gives the glass a mirrored or metallic appearance. Sticking to neutral shades like gray, charcoal, bronze, or green is your safest bet. These colors are widely accepted and will not raise flags during a tint inspection.

Medical Exemptions and Special Permits

Not everyone can tolerate regular window tint. Some people have medical conditions that make them extremely sensitive to sunlight. South Dakota recognizes this and offers a tint exemption for qualifying individuals. If you have a medical condition that requires you to limit your exposure to sunlight, you may be eligible for a special permit.

Who Qualifies for a Medical Exemption?

Conditions like lupus, porphyria, severe photosensitivity, and certain skin disorders may qualify you for an exemption. You will need a signed letter from a licensed physician that explains your condition and recommends limited sun exposure. This letter must be kept in your vehicle at all times. You can present it to law enforcement if you are stopped or questioned about your tint.

How to Apply for an Exemption

To apply, you need to submit your physician’s letter to the South Dakota Department of Public Safety. They will review your application and, if approved, issue a special permit sticker. This sticker must be displayed on your vehicle. Keep in mind that even with an exemption, your tint must still meet certain safety standards. The exemption allows darker tint than the standard 35% VLT limit, but it does not give you unlimited freedom to tint as dark as you want.

Penalties for Illegal Tint in South Dakota

Getting caught with illegal window tint is not worth the risk. South Dakota takes tint violations seriously, and the penalties can add up quickly. Here is what you need to know.

Fines and Costs

A tint violation in South Dakota typically results in a fine. The exact amount can vary depending on the county and the severity of the violation. In most cases, you can expect a fine ranging from $100 to $200 for a first offense. Repeat offenses may cost more. On top of the fine, you may also be required to remove the illegal tint and pass a vehicle inspection before your car can be legally driven again.

What Happens During a Traffic Stop?

If a law enforcement officer suspects your tint is too dark, they may pull you over. They will use a tint meter to measure the VLT of your windows. If your tint fails the test, you will likely receive a citation. In some cases, the officer may give you a warning and a deadline to fix the issue. However, this is not guaranteed. Always assume that an illegal tint will result in a fine.

How to Fix an Illegal Tint

If you receive a tint ticket, do not panic. The easiest fix is to remove the illegal tint film and replace it with a legal one. Many professional tint installers can help you choose a film that meets South Dakota’s VLT requirements. Once the tint is replaced, you can present proof of compliance to dismiss the ticket or reduce your fine. Keeping your receipt from the tint shop can also help if you need to dispute the citation.

Tips for Choosing the Right Tint for Your Vehicle

Now that you know the rules, let us talk about how to choose the right tint for your car. Picking the right film is about more than just looks. You want something that is legal, durable, and effective at reducing heat and glare.

Pick the Right VLT Percentage

For front side windows, choose a film with a VLT of 35% or higher. For rear side and rear windows, you have more freedom, but consider comfort and practicality. A 20% to 35% VLT on rear windows offers a good balance of style and function. If you want maximum heat rejection, look for films with a high infrared rejection rating, even if the VLT is higher.

Go With a Professional Installer

DIY tint kits are tempting because they save money, but they often lead to bubbles, peeling, and uneven application. A professional tint installer has the tools, training, and experience to do the job right the first time. They will also know the current South Dakota tint laws and can recommend films that keep you compliant. Many installers offer warranties on their work, which gives you peace of mind.

Check Local County Regulations

While South Dakota has statewide tint laws, some counties may have additional rules or enforcement practices. It is always a good idea to check with your local Department of Motor Vehicles or law enforcement agency before getting your windows tinted. Staying informed helps you avoid surprises.

Consider Factory Tint vs. Aftermarket Tint

Some vehicles come with factory tint from the manufacturer. Factory tint usually has a VLT of around 20% to 35%, depending on the vehicle. If your car already has factory tint on the rear windows, you may not need to add aftermarket film. However, factory tint does not count toward the front side window limits. You still need to ensure your front side windows meet the 35% VLT requirement. Keep in mind that aftermarket tint is applied after the vehicle is manufactured, and it is what law enforcement measures during a tint stop.

Common Mistakes People Make With Window Tint

Even well-meaning car owners make mistakes when it comes to window tint. Avoiding these common errors can save you time, money, and frustration.

• Buying tint without checking the law: Many people buy the darkest tint they can find without checking if it is legal in South Dakota. Always verify the VLT before purchasing.
• Ignoring the windshield rules: Tinting below the top 4 inches of the windshield is illegal, even if it looks cool. Stick to the shade band only.
• Skipping the certification sticker: South Dakota requires a legal tint sticker to be placed on the driver’s side window. Without it, you may be assumed to have illegal tint.
• Choosing style over safety: Dark tint looks great, but it can reduce your ability to see pedestrians, cyclists, and other vehicles at night. Prioritize safety and legality.
• Not keeping your exemption paperwork handy: If you have a medical exemption, carry the documentation with you at all times. An officer cannot read your mind, and they need proof.

How South Dakota Compares to Neighboring States

It helps to know how South Dakota’s tint laws stack up against nearby states. Each state sets its own rules, and the differences can be significant.

In Nebraska, front side windows must also allow more than 35% VLT, which is similar to South Dakota. Minnesota is stricter, requiring 50% VLT on front side windows. Iowa allows 70% VLT on front side windows, making it one of the most restrictive states in the region. Montana is more lenient, allowing any tint darkness on rear windows, much like South Dakota. Understanding these differences is especially helpful if you frequently travel across state lines or if you recently moved to South Dakota from another state.

State	Front Side Window VLT	Rear Window VLT	Windshield Tint
South Dakota	35% or higher	Any darkness	Top 4 inches only
Nebraska	35% or higher	Any darkness	Top 4 inches only
Minnesota	50% or higher	Any darkness	Top 4 inches only
Iowa	70% or higher	Any darkness	Top 4 inches only
Montana	No specific limit	Any darkness	Top 4 inches only

As you can see, South Dakota’s tint laws are moderate compared to neighboring states. They strike a balance between driver comfort and road safety. If you are unsure about the rules in any state you visit, always check the local vehicle code before tinting your windows.
