What an ignition interlock costs in Texas
Verified · next review
Texas 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.
Texas 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; Texas 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 Texas
The monthly fee matters less than how long you pay it, and that is set by the requirement rather than the provider. In Texas a first offense carries for the duration of the suspension, unless the court finds good cause to remove the device early The programme is run by Texas Department of Public Safety, on the 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 Texas rules and centers →

Cost questions in Texas
How much does an ignition interlock cost in Texas?
Texas 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 Texas cap what a provider can charge?
No. Texas 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 Texas charge on top of the device?
We have no separate state fee schedule on file for Texas. Reinstatement and licensing charges usually sit outside the interlock program itself — check with Texas Department of Public Safety, on the court order before you budget.
Where can I have an interlock fitted in Texas?
We index 1,005 certified installation points across 324 Texas 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.
