What an ignition interlock costs in Massachusetts
Verified · next review
Massachusetts 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.
Massachusetts 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; Massachusetts 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 Massachusetts
The monthly fee matters less than how long you pay it, and that is set by the requirement rather than the provider. In Massachusetts a first offense carries for the whole hardship license period; multiple-OUI offenders keep the device a further two years after full reinstatement. Since 1 July 2021 certain first offenders seeking a hardship license need one too The programme is run by Massachusetts RMV, Driver Control Unit, 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 Massachusetts rules and centers →

Cost questions in Massachusetts
How much does an ignition interlock cost in Massachusetts?
Massachusetts 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 Massachusetts cap what a provider can charge?
No. Massachusetts 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 Massachusetts charge on top of the device?
We have no separate state fee schedule on file for Massachusetts. Reinstatement and licensing charges usually sit outside the interlock program itself — check with Massachusetts RMV, Driver Control Unit before you budget.
Where can I have an interlock fitted in Massachusetts?
We index 158 certified installation points across 106 Massachusetts 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.
