What’s the difference between a DUI and a DWI? DUI: driving under the influence. Generally, people under the legal drinking age who are found to have consumed any amount of alcohol can be charged with DUIs. DWI: driving while intoxicated. People of all ages may be charged with a DWI if they are unable to perform their mental and physical capacities to the normal level due to alcohol and drugs. They may also be charged with a DWI if their BAC level is .08 or more. #dwi #dui #drunkdriving #driving
