Drink driving is the commonly used term for driving under the influence of alcohol. It refers to driving a motor vehicle while one’s blood alcohol content (BAC) is above the legal limit set by statute. The legal limit set by the state statutes varies, but in most cases it ranges from .08 to .10. For more information on the legal ramifications, see driving under the influence here.
