The rules

What Idaho requires

Idaho separates the administrative side from the court case: the Transportation Department handles the license suspension, the reinstatement fee and the restricted driving permit, while the court sets the sentence. The interlock belongs to the administrative track — it is what makes a restricted permit possible while the suspension runs.

  • First offense: Tied to the administrative license suspension; ITD collects the reinstatement fee and issues the restricted driving permit that the device makes possible
  • Lockout threshold: Set by the state-approved system meeting NHTSA standards
  • Program run by: Idaho Transportation Department, with the court setting the sentence

What the charge itself carries in Idaho: a second, a first offence and when it becomes a felony — the fine, the jail exposure and how long the licence stays restricted.

Why Idaho asks for the device

Federal crash records are the backdrop to the rules on this page. Read the share with care though: it depends heavily on how often police obtain an alcohol test, and that varies enormously between states.

Questions

Interlock questions in Idaho

Is an ignition interlock mandatory in Idaho?

Idaho separates the administrative side from the court case: the Transportation Department handles the license suspension, the reinstatement fee and the restricted driving permit, while the court sets the sentence. The interlock belongs to the administrative track — it is what makes a restricted permit possible while the suspension runs. As for how long: tied to the administrative license suspension; ITD collects the reinstatement fee and issues the restricted driving permit that the device makes possible.

How much is an interlock device per month in Idaho?

Idaho 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.

What are the consequences of an interlock violation in Idaho?

A recorded event is not automatically a violation, and that distinction decides most cases. Programs differ in what they count and how they count it: some add time per event, others ignore single events and act on a pattern, and several give you a written escape where a retest within five or ten minutes comes back clean. What is uniform is that the decision is made by Idaho Transportation Department, with the court setting the sentence from the vendor's report, not at the roadside. The mechanics, state by state and with the statute on each, are on our page about violations and lockouts.

How do I get the interlock restriction off my license in Idaho?

Not at the workshop, and not on the date in your paperwork. The state releases you first and the device comes out last: you finish the term including anything added to it, sit a final data download at the service center, let Idaho Transportation Department, with the court setting the sentence review the record, take what it issues to a licensing office to lift the restriction, and only then book the removal. Most programs also require a clean window before any of that starts — 180 days in Washington, the last 30 in New Jersey, three months in Maryland.

What blood alcohol level will fail an interlock in Idaho?

Idaho does not fix the number in the statute itself — it is set by the certifying agency in the device standard, and in practice sits between 0.02% and 0.025% BAC. Either way it is far below the 0.08% driving limit, which is why one drink shortly before a test is enough to fail it: the device is testing whether you drank, not whether you are impaired.

Is there an alternative to an ignition interlock device in Idaho?

Sometimes, and it is usually stricter rather than easier. The common substitute is continuous alcohol monitoring — a transdermal ankle bracelet that watches the person instead of the car, all day rather than at the ignition. North Carolina writes the trade directly into sentencing: 120 days of monitored abstinence can cut a 30-day minimum to ten, and 90 days can replace a seven-day term. The other alternative is not driving at all, which some states allow you to serve out instead, and which costs you the license for the whole period rather than the device.

Where can I get an ignition interlock device installed in Idaho?

We index 95 certified installation points across 44 Idaho cities, run by 6 approved providers, with the densest coverage in Boise, Coeur D' Alene, Idaho Falls. Install 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.
