Penalty for over-dark tint in South Dakota
Class 2 misdemeanor; fines up to $500. Most South Dakota tint enforcement happens during routine traffic stops — police can request a VLT reading on the side glass with a handheld meter.
Practical advice: stay one step above the legal limit if you can. A 35% film on fronts in a 35% state can read slightly under at the meter due to existing factory tint in the glass — running 40–50% leaves headroom.
Medical exemption in South Dakota
South Dakota allows a medical exemption for darker tint with documentation from a licensed physician. Conditions that commonly qualify include lupus, photosensitive disorders, melanoma history, and certain eye conditions. Process and required forms are available from the South Dakota DMV. Allow 2–6 weeks for processing.
