Aggravated Driving Under the Influence

Under SB1627 (April 2026), a DUI becomes aggravated — and potentially a felony — when any of these factors are present at the time of arrest: BAC of 0.15% or higher, an accident resulting in injury, a minor under 18 in the vehicle, eluding or fleeing a peace officer, reckless driving during the DUI, or speeding 20+ mph over the limit on residential roads (30+ on highways). Any single factor is sufficient to elevate the charge.

Under the current statute, aggravated DUI is classified as a Class B3 felony carrying up to 5 years in prison. However, the statute contradicts itself by also referencing misdemeanor treatment. This internal contradiction is actively being litigated and creates a significant defense opportunity — your attorney may argue the charge should be treated as a misdemeanor rather than a felony.

Between November 2025 and April 2026, Oklahoma passed five separate DUI laws. SB54 (November 2025) first made aggravated DUI a felony but was so broadly written that it effectively made nearly every first-offense DUI a felony. SB1627 (emergency law, April 2026) attempted to narrow the aggravating factors, but its contradictory language continues to create confusion. Attorneys, prosecutors, and judges are still debating the proper interpretation.

Unlike a standard first-offense DUI where jail time is unlikely, aggravated DUI carries a mandatory minimum of 10 days in jail or inpatient treatment. This minimum is enforced regardless of whether the charge is treated as a misdemeanor or felony. If treated as a felony, the maximum sentence is 5 years in prison.

Yes. The statute's contradictory language provides a strong argument for reducing the charge from felony to misdemeanor. Additionally, if the specific aggravating factor can be challenged (BAC below 0.15 due to rising blood alcohol, injuries that don't meet statutory requirements, reckless driving that was actually a minor lane deviation), the charge may be reduced to a standard DUI. Plea negotiations may also result in a reduction.

When you drink alcohol, your BAC continues to rise as alcohol is absorbed into your bloodstream — a process that can take 30-90 minutes. If you were tested 30-60 minutes after your last drink, your BAC at the time of testing may have been significantly higher than at the time of driving. This is particularly important for aggravated DUI where the 0.15 threshold determines whether the charge is a misdemeanor or felony. Expert toxicology testimony can demonstrate that the BAC was below 0.15 at the time of driving.

If the aggravated DUI is treated as a misdemeanor, a deferred sentence is available (first offense only). If treated as a felony, deferred sentences for felonies are extremely rare in Oklahoma — the statute generally prevents a second felony deferral. The availability of a deferred sentence depends heavily on how the court interprets the contradictory statute and on the defendant's criminal history.

Yes. Under SB1627, having a minor under 18 in the vehicle during a DUI is an aggravating factor that elevates the charge from a standard misdemeanor to an aggravated DUI. Additionally, the driver may face a separate charge of child endangerment under 21 O.S. § 852.1, carrying up to 4 years in prison and $5,000 in fines — even if no accident occurs.
