Types of DUI Cases We Handle in Norman

Oklahoma has several impaired driving offenses, and the charge you face depends on your BAC level, whether you were driving or simply in physical control of a vehicle, and your prior record. We handle all types of DUI and impaired driving cases in Norman, OK.

• First-offense DUI. Driving with a BAC of .08 or higher is a misdemeanor on a first offense, carrying 10 days to one year in jail, a fine up to $1,000, mandatory substance abuse assessment, and license consequences. Even a first conviction can disrupt your employment and driving privileges.
• Aggravated DUI. A BAC of .15 or higher triggers additional penalties including a mandatory 90-day ignition interlock device requirement and one year of supervision with periodic testing. Oklahoma’s recent legislative changes under SB 54 have expanded the consequences for aggravated DUI offenses.
• Felony DUI. A second or subsequent DUI within ten years is a felony punishable by one to five years in the Department of Corrections and a fine up to $2,500. Third and subsequent offenses carry even harsher penalties. Felony DUI convictions also trigger the 85% rule for certain violent offense classifications.
• DWI. Driving with a BAC between .06 and .07 while impaired is classified as DWI under Oklahoma law. While penalties are lower than DUI, a DWI conviction still creates a criminal record and can affect insurance rates and employment.
• Actual physical control (APC). You do not have to be driving to be charged. If you are in a parked vehicle with the keys accessible while intoxicated, Oklahoma law allows an APC charge under the same statute as DUI. The penalties mirror DUI penalties.
• DUI with child passengers. Operating a vehicle while impaired with a child under 18 in the car doubles the fine for the underlying DUI offense. Additional charges under Oklahoma’s child endangerment statute may also apply.

Oklahoma Legal Requirements for DUI

Oklahoma’s DUI laws are found in 47 O.S. § 11-902, which prohibits driving, operating, or being in actual physical control of a motor vehicle while under the influence of alcohol, drugs, or any intoxicating substance. The legal BAC limit is .08 for drivers 21 and older. For drivers under 21, Oklahoma enforces a zero-tolerance policy, meaning any measurable amount of alcohol can result in charges.

A first-offense DUI is a misdemeanor. The sentence includes 10 days to one year in jail, a fine up to $1,000, mandatory drug and alcohol assessment, completion of any recommended treatment program, attendance at a victim impact panel, and court costs. A BAC of .15 or higher adds an ignition interlock requirement and supervised testing.

A second DUI within ten years is a felony carrying one to five years in the Department of Corrections, a fine up to $2,500, and an extended license revocation period. The ten-year lookback period includes prior convictions from other states.

Oklahoma’s implied consent law requires drivers to submit to chemical testing when requested by law enforcement. Refusing a breath or blood test triggers an automatic license revocation of 180 days for a first refusal and three years for a subsequent refusal, even if no criminal conviction results. The Oklahoma Department of Public Safety administers the license revocation process separately from the criminal case.

The Impaired Driver Accountability Program (IDAP) provides an alternative to traditional license revocation. Participants must install an ignition interlock device, comply with monitoring requirements, and complete a substance abuse program. Enrollment in IDAP allows limited driving privileges during the revocation period.

DUI charges also carry custody consequences. A conviction can affect how a judge evaluates parental fitness in a custody proceeding, particularly regarding the child’s safety during visitation or parenting time.

Important Aspects of a Norman DUI Case

Challenging the Traffic Stop

Every DUI case begins with a traffic stop or an encounter with law enforcement. The officer must have reasonable suspicion of a traffic violation or criminal activity to initiate the stop. If the stop was not legally justified, everything that followed, including field sobriety tests and chemical testing, can be challenged through a suppression motion. We review the officer’s stated reasons for the stop, the dashcam and body camera footage, and the dispatch records to determine whether the stop was lawful.

Field Sobriety Test Accuracy

Standardized field sobriety tests, the walk-and-turn, the one-leg stand, and the horizontal gaze nystagmus test, are not as reliable as most people assume. These tests are affected by age, weight, medical conditions, footwear, road surface, weather, and the officer’s administration of the test. Even under ideal conditions, studies show significant error rates. If the tests were administered improperly or the results were interpreted incorrectly, we challenge their admissibility.

Breath and Blood Test Defenses

The Intoxilyzer and blood draw procedures must comply with strict protocols. The breath testing instrument must be properly calibrated and maintained. The operator must be certified. The observation period before the test must be completed correctly. Blood draws must follow chain-of-custody requirements, and the lab analysis must be performed by a qualified analyst. Deviations from any of these procedures create grounds to challenge the BAC result. And without a reliable BAC number, the prosecution’s case weakens significantly. Understanding these defense strategies is critical to building an effective case.

License Consequences and the Administrative Hearing

A DUI arrest in Oklahoma triggers two separate proceedings: the criminal case and an administrative license action through the Department of Public Safety. You have 15 days from the date of arrest to request an administrative hearing to contest the license revocation. Missing that deadline means your license is automatically revoked. We handle both the criminal defense and the administrative hearing to protect your driving privileges.

How DUI Affects Your Criminal Record

A DUI conviction, even a misdemeanor, stays on your criminal record. It shows up on background checks for employment, housing, and professional licensing. Certain careers, particularly those in healthcare, education, and law enforcement, are directly affected. For non-citizens, a DUI conviction combined with other factors can trigger immigration consequences. And if you are involved in a custody dispute, the other parent’s attorney will use the conviction against you.

DUI Charges Alongside Other Criminal Matters

DUI arrests in Norman frequently overlap with other charges. A traffic stop that starts as a DUI investigation can lead to drug possession charges if the officer discovers controlled substances in the vehicle. A DUI involving a collision may result in additional charges if someone was injured. Incidents involving a spouse or partner can escalate into domestic violence charges if a confrontation occurs during or after the arrest. We handle common defenses across all overlapping charges.

Deferred Sentencing and Record Protection

Oklahoma allows deferred sentencing in some DUI cases. Under a deferred sentence, you plead guilty, but the court delays entering the conviction while you complete probation, treatment, and other conditions. If you successfully complete the deferred sentence, the charge can be dismissed and you may be eligible for expungement. Not every DUI case qualifies, but when it is available, a deferred sentence can protect your record from a permanent conviction. Understanding probation requirements is essential if you pursue this path.
