No, 50% window tint is not universally legal in South Dakota. State law mandates front side windows allow over 35% light transmission, while rear windows may use up to 20% tint. Local jurisdictions, including Sioux Falls and Rapid City, enforce stricter rules via municipal ordinances. Non-compliance risks citations, with 2026 state audits expected to tighten enforcement.
Key Regulations for 50% Window Tint in South Dakota
- Front side windows: Must transmit more than 35% of light; 50% tint violates this threshold.
- Rear windows: Permitted up to 20% tint, but 50% exceeds this limit.
- Medical exemptions: Require documented proof from a licensed physician; temporary permits may apply.
South Dakota’s Division of Highway Patrol enforces these standards, with local law enforcement empowered to issue fines. Vehicles registered out-of-state must comply with South Dakota’s rules upon inspection. Dealers and installers face liability for non-compliant tint installations.
