The distinction between DUI and DWI charges in Oklahoma is crucial, though often misunderstood. While both involve operating a motor vehicle under the influence, they carry distinct legal consequences. 

What does DUI mean under Oklahoma law?

Pursuant to 47 O.S. § 11-902, operating a motor vehicle under the influence of alcohol or any other intoxicating substance is prohibited. This statute specifies that a BAC (Blood Alcohol Content) of 0.08 or above constitutes a DUI offense. Unlike DWI, DUI charges do not stipulate specific thresholds for intoxicating substances beyond alcohol.

What does DWI mean under Oklahoma Law?

On the other hand, 47 O.S. § 761 outlines DWI offenses, which occur when a driver’s BAC falls between 0.05 and 0.07. While still impaired, penalties for DWI are generally less severe compared to DUI violations.

Understanding Intoxicants Under Oklahoma Law 

Expanding on the notion of “intoxicants” beyond alcohol, Oklahoma law encompasses various substances, not limited to illicit drugs or prescription medications. Illicit drugs such as cocaine, ecstasy, fentanyl, and methamphetamine can lead to DUI charges. Moreover, any trace of a Schedule I drug in a driver’s system can result in additional legal consequences.

Beyond illegal substances, legally prescribed medications like anxiety and pain pills can impair driving and may lead to charges. Additionally, over-the-counter drugs, including cough syrups and nighttime cold medications causing drowsiness or lightheadedness, or other medications resulting in side effects can prompt legal action if they impair one’s driving ability.
