Question By: The terms OWI, DUI, and DWI refer to different legal designations for impaired driving offenses, and their meanings can vary depending on the state.
OWI (Operating While Intoxicated) generally refers to the act of operating a vehicle while impaired by alcohol or drugs. It is a broader term used in some states, including Wisconsin, to cover any form of impaired operation of a vehicle, not limited to driving. This can include being in control of the vehicle even if it is not moving.
DUI (Driving Under the Influence) is a more specific term that indicates driving a vehicle while under the influence of alcohol or drugs. DUI laws typically set a blood alcohol concentration (BAC) limit, commonly 0.08%, and apply to drivers whose ability to operate the vehicle safely is impaired by substances.
DWI (Driving While Intoxicated or Driving While Impaired) has dual interpretations based on the state. In some states, DWI means "Driving While Intoxicated" and is used interchangeably with DUI. In other states, it stands for "Driving While Impaired" and may cover impairment by substances other than alcohol, such as drugs, including prescription medications.
The primary difference among these terms lies in the legal definitions and usage in different jurisdictions. Some states may use OWI exclusively, while others might use DUI or DWI. The distinctions also affect the scope of the offense; for example, OWI can encompass broader circumstances of vehicle control compared to DUI or DWI, which are typically more narrowly focused on actual driving.
