DUI and DWI are often used interchangeably, but the terminology depends on the state. DUI stands for driving under the influence of alcohol, drugs, or a combination of both. DWI typically means driving while intoxicated.

Some states use the term DWI, while others use DUI. In California, the legal term used for impaired driving offenses is DUI. Although the wording differs from state to state, the charge generally refers to operating a vehicle while impaired.

If you were arrested for impaired driving in California, the case will be handled as a DUI under California law, regardless of whether another state might label the offense as DWI.
