South Dakota Tint Law

Summers in South Dakota can range from warm to hot; getting your car windows tinted will make your daily commute more comfortable.

Not only does window tint offer comfort, but it also has other benefits such as protection from exposure to harmful UV rays, preventing the upholstery of your vehicle from fading and cracking, saving money on air conditioning and also offering privacy.

But before you go ahead and get tinting on your vehicle’s windows, it is important to know the South Dakota tint law and, in this article, we’ll give you all the information you need about this.

Window tint installation in South Dakota

Window tint is legal in South Dakota, but it is governed by the rules and regulations which were first established in 1989.

These regulations were put in place to ensure overall safety. Read on to find out the permitted tint darkness and reflective levels in this state.

Permitted Window Tint Darkness

When it comes to South Dakota tint law, the most important thing to consider is the visible light transmission (or VLT) of the window tint. This is essentially the percentage of light that is allowed into the cabin.

For instance, if the VLT of the window tint is 50%, it means that it will allow only half of the incoming light to pass through, whereas if the VLT% is 20%, then the light allowed inside will only be 1/5th.

This means that the lower the VLT percentage, the darker the windows will be. And so, you should buy a tint film that is above the minimum VLT% listed by the state. 


Windshield: You are permitted to have a non-reflective tint above the AS-1 line
Driver-side windows: Should let in over 35% of light
Passenger-side windows: Should let in over 35% of light
Rear window: Should let in over 20% of light

The tint film used on vehicle windows can help to reduce the amount of light passing through the windows, which is measured by tint darkness or visible light transmission.

But at the same time, the tint film may also help to reflect the light that hits the vehicles. This is known as a tint reflection of the film. Tint reflection offers benefits such as reducing glare and heat.

According to South Dakota tint law, window tints on vehicles should not have any reflective or mirrored appearance.
