The terms DWI and DUI are often used interchangeably and in some jurisdictions you aren’t incorrect in doing so. However, the two terms have legally distinct meanings. DWI or driving while intoxicated is operating a motor vehicle after consuming enough alcohol to raise one’s blood alcohol content (BAC) to over the statutory limit. The limit is .08% in most states. DUI or driving under the influence is generally a lesser offense of operating a motor vehicle in a physically or mentally impaired state, especially after consuming drugs or alcohol. In some states, a DUI is commonly associated with a minor driving with alcohol in their system. To be sure on your jurisdiction’s definition, search within the state penal code. You will find specifics which define the rules of driving after having consumed alcohol.
