DUI vs. DWI: What's the Difference?
Confused about DUI versus DWI terminology? Here's a general, plain-English explanation of what these terms mean and why states differ.
Same core concept, different labels
DUI (driving under the influence) and DWI (driving while intoxicated or driving while impaired) generally describe the same underlying offense: operating a vehicle while impaired by alcohol or drugs. Which term a state uses is largely a matter of that state's specific statute language.
Some states use both terms for different situations
A handful of states use DUI and DWI to describe different severity levels or different types of impairment (for example, alcohol versus drugs), so it's worth understanding how your specific state defines each term.
Other related terms you might see
Some states use OWI (operating while intoxicated) or OUI (operating under the influence) instead of, or alongside, DUI and DWI. The underlying concept, driving while impaired, is generally consistent across these labels.
Why the label matters less than the specific statute
Regardless of which term applies, what actually determines the charge and potential consequences is your state's specific statute, the facts of the stop, and any test results, not the terminology alone.
Getting clarity on your specific charge
If you're unsure exactly what you've been charged with or what it means, your citation or arrest paperwork will reference a specific statute number, which an attorney can quickly explain in plain language.
