Window tint in South Dakota
South Dakota sits at 35% front side and both sedans and SUVs have a 20% limit on rear and back side windows, which is a bit tighter than what many other states allow in the back. There's no extra flexibility for larger vehicles in the rear, which is somewhat unusual. The wide-open landscape and intense sun on the plains make tint worthwhile despite the moderate rules.

Frequently Asked Questions
What is the legal window tint in South Dakota?
Front side windows need a minimum of 35% VLT. Back side windows require 20% VLT, and the rear window requires 20% VLT. Film cert required. Side mirrors required if rear tinted.
How much is a tint ticket in South Dakota?
A first offense is typically $50–$100. Repeat offenses can cost $100–$200. Fix-it tickets are available, giving you time to remove or replace the film.
What is combined VLT and why does it matter?
Your car's factory glass already blocks some light (usually around 70-80% VLT). When you add tint film, the combined VLT is lower than the film alone. For example, 35% film on 75% factory glass gives you about 26% combined VLT. The calculator above does this math for you.
Can I preview tint on my car before installing?
Yes. Car Editor's AI tint simulator lets you upload a photo of your car and see any tint level applied to it in seconds. You can try different VLT percentages on your actual vehicle before committing.
