What’s the difference between a DUI and a DWI and how do the laws differ in Virginia, DC, and Maryland?

You may hear the acronyms DUI and DWI used interchangeably and in Virginia and DC, they do mean the same thing. But in Maryland, they refer to different levels of impairment and the distinction could be important.

Location Matters When it Comes to Drinking and Driving Violations

In both Virginia and DC, the official charge for having more than the legal limit of alcohol or another substance in your system is a DUI, or Driving Under the Influence. People may use the term DWI to mean the same thing, but it is not an official charge in these jurisdictions. In Maryland, however, DWI stands for Driving While Impaired, and refers to lower levels of alcohol in the bloodstream than a DUI.

The following table outlines the differences in charges between Virginia, Maryland, and DC.
