What an ignition interlock costs in South Dakota
Verified · next review
South Dakota does not publish a price, so the honest answer is the national one: NHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. A quote far above that is the provider's, not the state's.
Three charges make up the bill, not one: fitting the device, keeping it on the car, and taking it out at the end. Over a full term the monthly fee is the bulk of it, which is why a cheap installation on a long requirement costs more than a dearer one on a short.
South Dakota publishes no figure, so here is the national one
NHTSA puts installation at $70–$90 and monitoring at about $70 a month, roughly $3–$4 a day. Only 14 jurisdictions publish their own numbers or cap what a provider may charge; South Dakota is not among them, so a quote well above the national range is the provider’s decision rather than the state’s.
What decides the total in South Dakota
The monthly fee matters less than how long you pay it, and that is set by the requirement rather than the provider. In South Dakota a first offense carries set by the court or supervising agency; the interlock is ordered case by case rather than by a fixed statutory term The programme is run by The court or supervising agency, with the 24/7 program run by the Attorney General, which is also who decides whether a recorded event extends it.
That is the part worth budgeting for: events add months, and months are what the bill is made of. What counts as a violation → · All South Dakota rules and centers →

Cost questions in South Dakota
How much does an ignition interlock cost in South Dakota?
South Dakota does not publish a price, so the honest answer is the national one: NHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. A quote far above that is the provider's, not the state's.
Does South Dakota cap what a provider can charge?
No. South Dakota does not publish provider prices at all, so the quote is the price. That is the argument for getting two of them: nothing constrains what a provider asks, and in states without a cap the same brand quotes differently in different cities.
What else does South Dakota charge on top of the device?
We have no separate state fee schedule on file for South Dakota. Reinstatement and licensing charges usually sit outside the interlock program itself — check with The court or supervising agency, with the 24/7 program run by the Attorney General before you budget.
Where can I have an interlock fitted in South Dakota?
We index 11 certified installation points across 8 South Dakota cities. Book with a provider the state approves rather than the nearest pin on the map: time on an unapproved device does not count toward the term.
