What is the difference between OUI, DUI and DWI?
New Hampshire law makes it a crime for a person to drive or attempt to drive a vehicle while “under the influence of intoxicating liquor or any controlled drug” or any combination of alcohol and drugs. It also makes it a crime to operate a vehicle with an alcohol concentration of 0.08 or more (or, if under age 21, 0.02 or more). There is no legal distinction between OUI, DUI or DWI. Regardless of what it is called, a conviction will have serious and long-term consequences. You should consult with a lawyer if you are charged with any of these crimes.
A. None. Different states use different terminology. Massachusetts employs the term OUI, which is an abbreviation for “operating under the influence.” Other states use either DUI, which stands for “driving under the influence” or DWI, signifying “driving while intoxicated.” They are all generically known as drunk driving.
