The fees nobody quotes you over the phone
These are charged on top of the three above, and they are where a cheap-looking Arizona quote turns expensive.
| Fee | Amount |
|---|---|
| ADOT fee per device installed (collected by your provider) | $20, charged again if the device moves to another vehicle |
- Providers must clearly post all client fees for installation, removal and inspection.
- A provider may not charge you to replace a device that turns out to be faulty.
What Arizona requires
Arizona requires a certified device with a camera and GPS that reports every test to the MVD in real time. The clock starts when your license becomes eligible for reinstatement or when the MVD receives the conviction — whichever is later — so installing early does not shorten anything.
- First offense: At least 12 months on a standard first conviction; longer at higher readings — 12 months for Extreme DUI at 0.15%, 18 months for Super Extreme at 0.20% (A.R.S. 28-1382)
- Lockout threshold: 0.020% — the engine will not start at or above that reading
- Program run by: Arizona MVD (Department of Transportation)
Why Arizona orders these devices
An interlock order is not a judgment about you personally — it is what the state does with every case of this kind, and the reason sits in the crash record.
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. The count covers fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. Cochise County runs at or below the Arizona average — the requirement is set state-wide regardless. What the device changes is measurable too: a car fitted with one cannot be started over the limit, which is why the order attaches to driving privileges rather than to the sentence.

Interlock questions in Sierra Vista
Where can I get an ignition interlock device installed in Sierra Vista, AZ?
We index 4 certified installation points in Sierra Vista, run by Intoxalock, Smart Start, LifeSafer and others. Addresses are listed above. Book with the provider your paperwork names, not the nearest one — a device approved in one state is not automatically approved in the next, and switching brands mid-term means a second installation fee.
How much does it cost to have an ignition interlock device installed in Arizona?
Arizona does not publish provider prices — they are set by the approved provider, not by the state. Nationally, nHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. The state publishes only its own charges: ADOT fee per device installed (collected by your provider) $20, charged again if the device moves to another vehicle. Quotes in Sierra Vista will sit around that unless the provider is charging for something the state does not require.
Can I drink one beer and still start the car in Arizona?
Almost certainly not. 0.020% — the engine will not start at or above that reading That is far below any drunk driving limit, which is the point: the device is not testing whether you are impaired, it is testing whether you drank. One drink shortly before a test is enough on most programs, and the fail is recorded whether or not you try again.
What does an ignition interlock device do?
An ignition interlock is a breath-alcohol tester wired into your car ignition. You blow into it before starting the engine; if your breath alcohol is above the state threshold, the engine will not start.
While you are driving, the device asks for rolling retests at random intervals. Every sample, skipped test, and lockout is recorded and sent to the agency monitoring your case.
