What an ignition interlock costs in New Jersey
Verified · next review
New Jersey 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.
New Jersey 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; New Jersey 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 New Jersey
The monthly fee matters less than how long you pay it, and that is set by the requirement rather than the provider. In New Jersey a first offense carries 3 months at 0.08–0.10% BAC; 7–12 months at 0.10–0.15%; 12–15 months at 0.15% or higher The programme is run by New Jersey Motor Vehicle Commission, on the sentencing court order, 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 New Jersey rules and centers →
What the New Jersey term actually adds up to
New Jersey sets 3 months for a first offense, and that is the multiplier that matters. At the national reference of about $70 a month, the monitoring alone comes to about $210 over the term, before the $70-plus fitting fee and anything charged at removal.
Which is why the monthly rate decides the bill and the installation deal does not: one extra month costs more than the gap between the cheapest and dearest fitting. And the term is a floor — events recorded by the device push it further out.

Cost questions in New Jersey
How much does an ignition interlock cost in New Jersey?
New Jersey 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 New Jersey cap what a provider can charge?
No. New Jersey 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 New Jersey charge on top of the device?
We have no separate state fee schedule on file for New Jersey. Reinstatement and licensing charges usually sit outside the interlock program itself — check with New Jersey Motor Vehicle Commission, on the sentencing court order before you budget.
Where can I have an interlock fitted in New Jersey?
We index 175 certified installation points across 114 New Jersey 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.
