Overview of Oklahoma DUI Law

Oklahoma law defines several ways prosecutors can prove a DUI. You violate the law if you:

Have a blood or breath alcohol concentration of 0.08 or higher within two hours of arrest,
Are under the influence of alcohol,
Have any amount of a Schedule I controlled substance or metabolite in your system,
Are under the influence of any intoxicating substance other than alcohol, or
Are under the combined influence of alcohol and another intoxicating substance that makes you incapable of safely operating a vehicle.

Elements the State Must Prove

To convict you, prosecutors must establish each element beyond a reasonable doubt:

You were driving or in actual physical control of a vehicle,
On a public road, turnpike, or private lane providing access to dwellings, and
You were under the influence as defined by one of the categories above.

These elements mirror Oklahoma’s OUJI-CR 2d 6-18 & 6-20 jury instructions.

Misdemeanor vs Felony DUI in Oklahoma

A first-offense DUI is generally a misdemeanor. A conviction carries:

10 days – 1 year in jail,
Up to a $1,000 fine, and
Mandatory alcohol/drug assessment and completion of all recommended treatment.

Any subsequent offense within 10 years after completion of a prior sentence or deferred judgment is a felony DUI. Felony classification and penalties depend on prior convictions:

First Felony DUI (Class C2 Felony)

Imprisonment as provided in 21 O.S. § 20M, up to 7 years,
Fine up to $2,500,
Mandatory assessment and treatment, plus at least 5 days in jail if no residential treatment is ordered.

Second Felony DUI (Class B4 Felony)

1 – 10 years in prison,
Fine up to $5,000,
Ignition interlock device and 240 hours of community service if treatment not residential for 10 days.

Third or Subsequent Felony (Class B3 Felony)

1 – 20 years in prison,
Fine up to $5,000,
480 hours community service, interlock device, and one year of supervision with testing.

Enhanced penalties also apply when a child under 18 is in the vehicle, doubling the fine and potentially adding charges under 21 O.S. § 852.1 (child endangerment while DUI).

Collateral Consequences of an Oklahoma DUI Conviction

Driver’s license revocation by the Department of Public Safety (DPS),
Increased insurance rates or loss of coverage,
Employment barriers for positions requiring driving or security clearances,
Mandatory installation of an ignition interlock device after reinstatement, and
Public criminal record that can affect housing and professional licensing.

How Oklahoma Prosecutors Prove a DUI Case

Prosecutors typically rely on:

Officer observations of driving behavior and field sobriety tests,
Breath or blood test results administered within two hours of arrest,
Bodycam or dash-cam footage,
Statements made by the driver, and
Testimony from a certified Drug Recognition Expert (DRE) if drugs are alleged.

Common Defense Strategies to DUI Charges

Challenging the legality of the traffic stop or roadblock,
Attacking the accuracy and calibration of the breath test device,
Questioning the timing or administration of field sobriety tests,
Proving improper procedures under Oklahoma’s implied consent law, and
Raising medical conditions or other non-impairment causes for symptoms.

Key Oklahoma DUI Cases

Newlun v. State: The Court of Criminal Appeals held that a DUI committed more than 10 years after completion of a previous sentence is a misdemeanor, not a felony. This decision clarified the 10-year look-back rule under § 11-902.

State v. Salathiel: The Court ruled that 2011 amendments expanding what counts as a prior conviction (deferred pleas) cannot be applied retroactively. Only pleas entered after the amendment’s effective date qualify for felony enhancement.
