Is a DUI a felony in Oklahoma?
Verified · next review
On the second inside ten years — and treatment is a sentence here. Oklahoma reaches felony on a second conviction within ten years, and then offers a genuinely different sentence: 28 days of treatment followed by 30 days of aftercare at your own expense, instead of one to five years in the custody of the Department of Corrections. The catch is written in — if that treatment does not include at least five days as an inpatient, you serve at least five days anyway. A second felony conviction runs to seven years, a third to ten.
Written any number of ways — a 3rd DUI, a DUI 3rd, a felony DUI, or simply a DUI in OK — and the paperwork will use none of them. Oklahoma charges it under a section number, and that is what decides the range below.
Grade. Felony
Confinement. 1 to 5 years, or 28 days of treatment with aftercare
Fine. Up to $2,500

The device is a separate track
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.
In Oklahoma the interlock term runs 180 days and is administered by Board of Tests for Alcohol and Drug Influence, with driving privileges issued by Service Oklahoma — which is why a plea that settles the criminal case does not settle the device. What counts as a violation on it, and what an agency adds to the term, is its own arithmetic: violations and lockouts. Getting it off at the end is a procedure of its own too — removal and waivers.

Does an interlock come with it in Oklahoma?
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. The device requirement and the criminal penalty are separate tracks: one is handled by the court, the other by Board of Tests for Alcohol and Drug Influence, with driving privileges issued by Service Oklahoma.

Requesting a consultation connects you with an independent attorney or a legal referral service, who decide separately whether to take your case.
