How to read these numbers
Three details trip up more drivers than the percentages themselves. First, the limit applies to the combined reading of glass plus film, and factory glass is never perfectly clear, so a film's box rating always overstates what a meter will read on the car. Second, the windshield is its own category everywhere: below the AS-1 line (the small marking near the top corner of the glass), meaningful tint is illegal across both countries, whatever the side windows allow. Third, reflectivity is regulated separately from darkness, and mirrored or metallic film fails in most jurisdictions even at a legal VLT.

South Dakota tint law questions, answered
What is the legal tint limit in South Dakota?
Front side windows: 35%. Back side windows: 20%. Rear window: 20%. Where a figure is given it is a minimum VLT, meaning the share of light that must still pass through the glass and film together, so a higher number requires a lighter film.
Is 5% limo tint legal in South Dakota?
Not on the front side windows: South Dakota requires them to pass at least 35% of light, and 5% film blocks far more than that. Behind the driver the floors are 20% on the back side windows and 20% on the rear window, so 5% film fails there as well.
What is the darkest legal tint in South Dakota?
The darkest legal film on the front side windows in South Dakota is 35% VLT. Of the shades shops commonly stock, 70%, 50% and 35% pass there, while 20% and 5% do not. Behind the driver the floors are 20% on the back sides and 20% on the rear window. A lower VLT number is a darker window.
Is a medical exemption for darker tint available in South Dakota?
Yes. South Dakota provides a medical exemption route for documented photosensitivity conditions. The paperwork has to travel in the vehicle, and an exemption attaches to the person's own car rather than to any car they drive.
What does South Dakota allow on the windshield?
Strip above the AS-1 line. The windshield is regulated separately from side glass everywhere in North America, so whatever shade is legal on the doors says nothing about what is permitted up front.
Is South Dakota stricter than other states on window tint?
South Dakota requires 35% on the front side windows. Of the jurisdictions that publish a numeric limit, 13 require a lighter film than that and 16 allow darker. The same front-side figure applies in Connecticut, Hawaii, Idaho, Illinois.
