Drunk driving means driving under the influence of alcohol. A person is considered as drunk driving if the alcohol content in ones blood is above the legal limit set by statute, which supposedly is the level at which a person cannot drive safely. In almost all states public policy mandates a strict interpretation and rigorous application of the drunk-driving laws. However, the level of drunk driving set by the state statutes varies from state to state. It is to be noted that in the eyes of the law there is no distinction in culpability or punishment between drunk drivers and those who allow the drunk to drive. Drunk driving is also called as driving under the influence of alcohol (DUI. While in some states it is called as driving while intoxicated (DWI), operating while impaired (OWI), or operating a vehicle under the influence (OVI).
