What Oklahoma requires
Oklahoma counts in "active interlock days" — a day only counts if the device is installed, powered and not in permanent lockout. Every program also ends with a 90-day violation-free stretch, so a bad reading near the finish line pushes your completion date out rather than just costing a fee.
- First offense: 180 active interlock days for a first revocation, 365 for a second, 730 for a third or later — and the last 90 days of each must be violation-free
- Lockout threshold: Set by the device the Board of Tests certifies; a day counts toward the program only while the device is installed, powered and out of permanent lockout
- Program run by: Board of Tests for Alcohol and Drug Influence, with driving privileges issued by Service Oklahoma
Why Oklahoma 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. Custer County runs at or below the Oklahoma 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 Weatherford
Where can I get an ignition interlock device installed in Weatherford, OK?
We index 2 certified installation points in Weatherford, run by Intoxalock. 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 Oklahoma?
Oklahoma publishes its own figures rather than leaving it all to vendors: $150 to $350 to fit the device and $99.99 to $114.99 a month while it stays on the car. Removal is billed separately at the end of the term.
Can I drink one beer and still start the car in Oklahoma?
Almost certainly not. Oklahoma does not print one fixed number in the statute — the level is set by the certifying agency in the device standard, typically between 0.02% and 0.025% BAC, far below the 0.08% driving limit. 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.
