What is the minimum alcohol concentration that results in a DUI citation?

The minimum alcohol concentration that results in a DUI citation is typically set at 0.08%. This standard is based on research indicating that drivers at or above this level are significantly impaired and pose a higher risk of being involved in accidents. It reflects a consensus among various jurisdictions, as many states have adopted this threshold in line with federal guidelines.

The rationale behind this limit is that alcohol impairs cognitive functions, coordination, and reaction times, which are critical for safe driving. As a result, drivers with a blood alcohol concentration (BAC) of 0.08% or higher face legal penalties, including citations and potential arrest, for driving under the influence. Understanding this standard is crucial for recognizing responsible drinking limits and the potential consequences of impaired driving.
