Overview
Oklahoma distinguishes between DUI (driving under the influence, BAC 0.08%+) and DWI (driving while impaired, BAC 0.06% to 0.079%), creating a two-tiered system that is unusual among states. Oklahoma uses a 10-year lookback period for DUI enhancements, and a second DUI offense is already a felony — one of the toughest escalation thresholds in the country. The state also has a separate administrative process through the Department of Public Safety that imposes license revocation independent of court proceedings. Oklahoma's 'Erin's Law' provisions impose severe penalties for DUI offenses causing great bodily injury or death.

Implied Consent Law
Under 47 O.S. § 751, any person operating a motor vehicle in Oklahoma is deemed to have given consent to chemical testing of blood or breath when arrested for DUI. The arresting officer selects the type of test. Drivers are informed of the consequences of refusal at the time of the request.
Refusal penalties: First refusal: 180-day license revocation and mandatory IID for 18 months upon reinstatement. Second refusal within 10 years: 1-year revocation and IID for 3 years. Third refusal: 3-year revocation and IID for 5 years. Refusal also triggers an automatic administrative hearing with DPS and may be used as evidence at trial.
Aggravating Factors
| Factor | Impact |
|---|---|
| BAC of 0.15% or higher (aggravated DUI) | Enhanced penalties including longer license revocation (180 days vs. 30 days on first offense), extended IID requirements (18 months vs. 6 months), and higher mandatory treatment levels |
| Child passenger under 18 in vehicle | Separate felony charge of child endangerment (punishable by 1–4 years in prison); DUI penalties also enhanced |
| Prior felony DUI conviction(s) | Each subsequent felony DUI escalates maximum prison time: 5 years (2nd), 10 years (3rd), 20 years (4th+). Mandatory minimum of 1 year applies to all. |
| Causing great bodily injury while DUI | Felony charge carrying up to 20 years in prison; separate from the DUI charge itself; victim restitution mandatory |
| Driving with revoked or denied license due to prior DUI | Separate felony charge of driving after former revocation; 1 to 5 years in prison; consecutive sentencing possible |
| Refusal to submit to chemical testing | Automatic license revocation of 180 days to 3 years; extended IID requirement; refusal admissible as evidence of guilt at trial |
DUI with Injury
Classification: Felony
DUI causing great bodily injury is a felony punishable by up to 20 years in state prison. DUI causing death (DUI manslaughter) carries 4 years to life in prison, with a mandatory minimum of 4 years. If the offender has prior DUI convictions, sentences for vehicular homicide are significantly enhanced. Victim restitution is mandatory, and the offender's license is revoked for a minimum of 3 years.
Underage DUI
Oklahoma has a strict zero-tolerance policy for underage drinking and driving. Any measurable amount of alcohol for a driver under 21 triggers a DWI charge (driving while impaired). Penalties include license revocation for 6 months (first offense) or 1 year (subsequent), mandatory community service, substance abuse assessment, and fines up to $500. If the underage driver's BAC is 0.08%+, full adult DUI penalties apply.
Diversion Programs
Program: Deferred Sentence / DUI Court
Oklahoma allows deferred sentencing for first-offense DUI where the court delays imposing a sentence while the defendant completes probation conditions including substance abuse treatment, community service, and monitoring. Upon successful completion, the case may be dismissed and eligible for expungement. Oklahoma also operates specialty DUI Courts in several counties that provide intensive supervision and treatment as an alternative to incarceration for repeat offenders.
Eligibility: Deferred sentencing is generally available for first-offense misdemeanor DUI defendants who plead guilty or no contest. It is not available for felony DUI (2nd+ offense) unless the court has a DUI Court program. DUI Courts typically accept second and third offenders assessed as having substance use disorders. Eligibility for any diversion is at the court's and prosecutor's discretion.
How Long a DUI Stays on Your Record
A DUI conviction remains on your Oklahoma driving record permanently. Criminal records are also permanent unless expunged. Under Oklahoma law, a first-offense misdemeanor DUI that received a deferred sentence may be eligible for expungement after the deferral period ends and all conditions are met. Felony DUI convictions are generally not eligible for expungement. The 10-year lookback period applies only to penalty enhancement for new charges.
