Oklahoma DUI Laws Explained

Oklahoma DUI law is codified at 47 OS § 11-902. The statute covers driving under the influence of alcohol or drugs and — distinct from most states — also covers Actual Physical Control (APC), which is the offense of being intoxicated while in physical control of a vehicle even without driving it. APC is regularly charged when a driver is found asleep in a parked car with the keys in the ignition or within reach.

The legal threshold

Oklahoma's per-se DUI thresholds:

• Adults 21+: 0.08% BAC.
• Drivers under 21: 0.02% BAC (zero-tolerance).
• Commercial drivers (CDL): 0.04% BAC.
• Aggravated DUI: 0.15% BAC or higher.

Oklahoma also charges DUI on impairment evidence below the per-se threshold, when officer observations, field sobriety tests, or Drug Recognition Expert evaluations support a finding of impairment.

The APC (Actual Physical Control) charge

Oklahoma's APC offense applies when a person is intoxicated and in physical control of a motor vehicle, even when the vehicle is not moving. Common APC scenarios:

• A driver sleeps in the parked car with the keys in the ignition (engine off).
• A driver pulls into a parking lot, stops the car, and remains intoxicated in the driver's seat with the keys accessible.
• A driver moves the car a few feet to a "safer" location while still intoxicated.

Oklahoma courts have repeatedly upheld APC convictions where the defendant's "intent to operate" can be inferred from the circumstances. The per-se thresholds and penalties for APC mirror those for DUI — the practical effect is that a driver's choice to "sleep it off" in the car can still result in conviction. Many Oklahoma DUI defense attorneys advise clients to leave the car and go elsewhere (a friend's couch, a hotel, an Uber) rather than relying on the parked-car defense.

Administrative revocation

After a DUI or APC arrest where the BAC was 0.08% or higher (or the driver refused chemical testing), the arresting officer typically confiscates the driver's license and issues a temporary 30-day permit. Service Oklahoma then imposes a 6-month administrative revocation on a first offense, which begins on day 31 unless a hearing is requested.

The administrative hearing

The driver may request an administrative hearing with Service Oklahoma's Driver Compliance Division within 30 days of the arrest. The hearing addresses three narrow questions: did the officer have probable cause for the stop, was the chemical test properly administered, and did the driver fail or refuse the test. A favorable ruling prevents the administrative revocation; an unfavorable one allows it to take effect.

First-offense criminal penalties

A first-offense DUI in Oklahoma is a misdemeanor with:

• 10 days to 1 year in county jail (probation often replaces jail on a first offense without aggravators).
• Up to $1,000 in fines plus court costs.
• 6-month criminal license revocation (overlapping with the administrative revocation).
• Mandatory installation of an ignition interlock device (IID) for 18 months as a condition of any modified license or post-revocation reinstatement.
• Mandatory completion of an Oklahoma alcohol/drug assessment, plus any treatment or DUI school the assessment recommends.
• SR-22 financial responsibility filing for 3 years — see Oklahoma insurance.
• Probation lasting 1-2 years.
• Victim Impact Panel attendance (a one-time educational session run by MADD or similar).

Aggravated DUI at 0.15% BAC

A measured BAC of 0.15% or higher is automatically an Aggravated DUI under Oklahoma law, with enhanced penalties:

• Mandatory minimum jail time on first offense.
• Higher fine ceiling.
• Mandatory IID for 4 years rather than the standard 18 months.
• Mandatory inpatient or intensive outpatient treatment.

Repeat offenses

A second DUI within 10 years is a felony under Oklahoma law — 1 to 5 years in state prison and up to $5,000 in fines. A third DUI within 10 years carries 1 to 10 years in prison and up to $5,000 in fines. Oklahoma's 10-year lookback applies to both DUI and APC convictions, so an APC from 8 years ago counts toward the felony enhancement on a new DUI charge.

Refusal to take a chemical test

Oklahoma's implied-consent law presumes that any driver who operates a motor vehicle on Oklahoma roads has consented to a chemical test if reasonably suspected of DUI. Refusing the test triggers a 6-month administrative revocation, longer for subsequent refusals. The refusal is admissible against the driver at trial and typically does not prevent the underlying DUI charge from proceeding.

Drug-related DUI

Oklahoma DUI also covers operation under the influence of any drug — illegal, prescription, or in some cases legal recreational. There's no per-se threshold equivalent to the 0.08% alcohol limit; impairment is established through Drug Recognition Expert evaluations, officer observations, and chemical tests of blood or urine. Marijuana DUI in Oklahoma is treated similarly to other drug DUI charges, despite Oklahoma's medical-marijuana legalization — having a valid medical-marijuana card does not exempt a driver from impaired-driving charges.
