Country star George Jones pleaded guilty in a Tennessee courtroom Wednesday to drunken driving for a March 6 accident that nearly killed him, and he promised to get help for his drinking problem. “I’ll get my mind straight,” Jones vowed after Judge Donald P. Harris approved a plea bargain calling for a $550 fine but no jail time. “I think there will be no more problems at all out of me.” Jones, 67, pleaded guilty to driving while impaired and violating the open container law. A reckless driving charge will be dismissed in a year if he completes an alcohol counseling program and stays out of trouble. He keeps his license.
