Oklahoma laws governing underage driving under the influence (DUI) have always been strict. However, legislative changes set out in Senate Bill 54, implemented from 1 November, 2025, have lowered thresholds and increased penalties. Oklahoma lawmakers hope that these extremely strict underage DUI laws will deter offenses. DUI for minors falls into two main categories.
Zero Tolerance For Underage Drinking and Driving
Under 47 O.S. § 11-902, a blood or breath alcohol concentration (BAC) threshold of 0.08% is imposed. However, Oklahoma law prescribes a zero-tolerance policy for drivers or persons in actual physical control of a vehicle who are under 21. The presence of any detectable amount of alcohol will therefore be considered a DUI, even if it is well below the legal limit for adults.
The term “actual physical control” means that an underage person who has consumed any intoxicating substance may be charged with a DUI even if the vehicle is not in motion. For example, a person sitting in the driver’s seat of a vehicle with access to its keys must comply with the same laws they would be subject to if they were actually driving.
Minors with a BAC of up to 0.08%
Oklahoma’s zero-tolerance approach means that any measurable blood alcohol content (BAC) constitutes a DUI. For a minor found guilty of a DUI with a BAC of up to 0.08%, the following penalties, with mandatory minimums, may apply:
- 1st offense: License revocation for 6 months, fines of up to $500, and 20 hours of community service
- 2nd offense: License revocation for 12 months, fines of up to $1,000, and 240 hours of community service
- 3rd offense: License revocation for 36 months, fines of up to $1,000, and 240 hours of community service
A judge may impose additional penalties beyond these. For example, they may require enrollment in a treatment program or the installation of an ignition interlock device. A judge may also decide that it is appropriate to suspend driving privileges for longer.
Per 47 O.S. § 6-107, Oklahoma courts must notify the Department of Public Safety about underage DUI offenses, and they will suspend or deny driving privileges for 6 months to 2 years, or until the offender reaches the age of 21.
DUI When Minors Have a BAC of 0,08 or More
If a minor has a BAC of 0,08 or more, a level that would result in DUI charges for adults, they will face the same charges and penalties as an adult driver would.
- 1st offense: License revocation for 6 months, fines of up to $1,000, and 10 days to a year of jail time, which may be deferred
- 2nd offense: License revocation for 12 months, fines of up to $2.500, and 1-5 years of jail time
- 3rd offense: License revocation for 36 months, fines of up to $5,000, and up to 10 years of jail time
Serious as this may already sound, you should also consider that underage DUI can lead to felony charges.
When Underage DUI is Considered a Felony Under Oklahoma Law
An underage DUI becomes a felony DUI under certain aggravating circumstances. These include:
- Causing a crash after consuming any amount of alcohol or drugs
- Speeding 20mph over the limit or 10 mph over the limit in a school zone
- Transporting a child under the age of 15
- Repeat offenses, especially when they occur within a short timeframe
- A BAC of 0.15%
- Attempting to elude law enforcement
If found guilty of a felony DUI, a young person may have a permanent record that disadvantages them in several ways. For example, it may affect career, employment, or educational opportunities.
The harsh penalties imposed for underage DUI in Oklahoma are intended to act as a deterrent, and parents and teachers should have frank conversations with young people in their care about DUI and its consequences. If an underage person close to you already faces DUI charges, it may be advisable to appoint an underage DUI attorney.
