A Tennessee man was arrested after a law enforcement officer pulled him over for making an illegal turn on Interstate 40. Upon approaching the vehicle and speaking with the driver, the officer reports that the man had blood-shot eyes and was displaying behavior that is often associated with intoxicated driving. After a failed sobriety test, the driver was arrested.
BAC levels, or blood alcohol concentration levels, indicate the amount of alcohol in a driver's bloodstream. Law enforcement officers administer certain tests to determine the BAC levels of a driver. In Tennessee, a BAC of .08 percent or higher is considered drunk driving and is grounds for arrest. However, there are certain circumstances in which a driver could be arrested for a lower BAC.
