What an ignition interlock costs in Colorado
Verified · next review
Colorado 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.
Colorado 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; Colorado 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 Colorado
The monthly fee matters less than how long you pay it, and that is set by the requirement rather than the provider. In Colorado a first offense carries 9 months for a first offense below 0.149% (running alongside the revocation); 2 years at 0.15% or higher, and 2 years automatically for refusing the test The programme is run by Colorado DMV (Department of Revenue), 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 Colorado rules and centers →
What the Colorado term actually adds up to
Colorado sets 9 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 $630 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 Colorado
How much does an ignition interlock cost in Colorado?
Colorado 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 Colorado cap what a provider can charge?
No. Colorado 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 Colorado charge on top of the device?
We have no separate state fee schedule on file for Colorado. Reinstatement and licensing charges usually sit outside the interlock program itself — check with Colorado DMV (Department of Revenue) before you budget.
Where can I have an interlock fitted in Colorado?
We index 286 certified installation points across 79 Colorado 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.
