DUI in Oklahoma: the law, the limits and the device
Verified · next review
Oklahoma calls it DUI — driving under the influence, and you will see drunk driving used for the same offense. What follows is what this state sets, taken from its own published rules rather than from a national summary.
What Oklahoma law actually 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

DUI vs DUI in Oklahoma
In Oklahoma there is one offense and one label. If you have seen DWI, OWI or OVI used elsewhere, that is another state’s vocabulary for the same conduct — nothing about the seriousness changes when you cross a state line, only the letters on the paperwork.
Whatever it is called, the licensing consequence is the same shape: a suspension, then the device as the condition of driving again. All six abbreviations, side by side →
Can you get a DUI on a bike or a horse in Oklahoma?
It turns on one word in the statute. Where the law says “vehicle”, no engine is required and the charge can reach a bicycle, a horse or a mobility scooter. Where it says “motor vehicle”, the analysis is different. This is decided by your state’s own wording, not by national custom, and it is the first thing to check before assuming a bike ride home is safe.
How often this happens in Oklahoma
Federal crash records show the scale the state is legislating against, and how it compares with the country.
Cases are heard where the stop happened, and volume shapes local practice. These OK counties record the most:

What it costs to get driving again in Oklahoma
Oklahoma is one of the few states that publishes what a provider may charge, so a quote here is checkable against the regulation rather than against another quote.
The two clocks in Oklahoma
The court case and the licensing case run separately. The licensing side moves first, and in the strictest states the window to request a hearing is measured in days — it runs whether or not you have hired anyone.

The county that hears your case is set by where the stop happened, and local practice differs across the state.
DUI questions in Oklahoma
Is it called DUI or DUI in Oklahoma?
Oklahoma uses DUI — driving under the influence. You will also see drunk driving used for the same thing. The label follows the state, not the seriousness of what happened, so paperwork from elsewhere may say something different about identical conduct.
What is the legal limit in Oklahoma?
0.08% for drivers 21 and over, as in every state except Utah, which sits at 0.05%. Below the limit you can still be charged if an officer documents impairment. The reading that triggers the interlock here is a separate number: 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
How long does the interlock stay on after a first offense in Oklahoma?
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 The program is run by Board of Tests for Alcohol and Drug Influence, with driving privileges issued by Service Oklahoma.
Can you get a DUI on a horse or a bicycle in Oklahoma?
The answer is in whether the statute says “vehicle” or “motor vehicle”. Where it says vehicle, no engine is needed and the charge can reach a bike or a horse; where it says motor vehicle, it cannot. This is one of the most searched questions in the whole subject and one of the most confidently answered wrongly — the wording of your own state decides it.
