Window Tinting in South Dakota – What Does the Law Say?

Tint laws can have confusing wording, so we’re going to take a closer look at each window of your vehicle and see exactly how dark the windows can be.

Can Windows Be Tinted in South Dakota?

Front Windshield Above the AS-1 Line: The front windshield above the AS-1 line can be tinted. However, the rest of the windshield cannot be tinted and must remain clear of any cracks. If your vehicle does not have an AS-1 line, the tint can come down to the lowest point of your sun visor.

Other Windows Can Be Tinted: All other windows in the vehicle can be tinted to a certain degree. The tint varies from 20% darkness up to 35% darkness. South Dakota law allows a 9% variance on these percentages, giving you a bit of leeway.

What Windows Can Be Tinted in South Dakota?

Window tint laws vary quite a bit between states, with some not allowing any tint at all on certain windows, others allowing a rather dark tint on windows. Luckily, the state of South Dakota gives you a nine percent enforcement tolerance, so if you requested a certain percentage tint and got a percentage or two darker than you should have, you will still be within the law.

  • Front Windshield: The front windshield of your vehicle must be non-reflective with clear, transparent glass. Above the AS-1 line, you may tint the windows to block out some of the sun’s harmful rays. If you don’t have an AS-1 line, the lowest point on your sun visor is also acceptable.
  • Back Windshield: The rear windshield of your vehicle must have a light transmittance of 20% or more to remain legal. With the enforcement tolerance being 9%, you can have a rear windshield with tint as dark as 11% and remain legal. However, with that dark of a tint, you are more likely to be a target to law enforcement.
  • Driver & Passenger Windows: The windows to the immediate left and right of the driver, including any front window vents, must allow 35% or more light transmittance to be legal. The tint cannot be made to appear metallic or mirrored in appearance. The nine percent enforcement variance applies to these windows as well.
  • Rear Side Windows: The windows located behind the passenger and driver seat must have a light transmittance of no less than 20%. This is the same rule that applies to the rear windshield. Any windows that are tinted are required to have a sticker of certification from the installer or manufacturer.
  • Restricted Colors: According to Chapter 32-15 of the South Dakota law, there are no specific laws or regulations against colored tint.

South Dakota Window Tint Law Medical Exemption

Some states will allow for a much darker tint on certain windows of the vehicle if the driver or someone who frequently drives the vehicle has a medical condition.

Some medical conditions such as autoimmune and allergy conditions cause people to be sensitive to sunlight, and therefore they need darker tinting to drive their vehicles safely.

In the state of South Dakota, they do not allow medical exemptions, meaning there is no way to get darker tint than what is allowed by the law.
