District Attorney Kim Helper of Williamson County said Thursday that Haynesworth was indicted Monday on charges of reckless driving and having expired registration.
Haynesworth, a former Titan who signed with the Redskins last month, was released on $1,000 bond after surrendering Wednesday. Maximum punishment is six months in jail and a $500 fine on the reckless driving charge and 30 days in jail and a $50 fine for the other charge.
The charges come from a Dec. 13 incident in which Haynesworth tried to pass another driver, who crashed into a concrete median.
Chad Speck, Haynesworth's agent, didn't respond to an e-mail Thursday seeking comment. He said previously that his client pulled over after the accident, called police and did not leave until cleared by an officer.
Haynesworth is scheduled for arraignment March 30 in Williamson Circuit Court in Franklin, just south of Nashville. Helper would not speculate how long the case would be in the courts.
Since the accident, on Interstate 65 south of Nashville, Corey Edmondson has needed a hip replacement and is unable to move except with a walker or in a wheelchair, said his attorney, Jon Perry.
"I am not surprised at all by the indictment," Perry said Thursday. "This accident could have very easily killed Corey."
Haynesworth, an All-Pro, signed a $100 million, seven-year contract Feb. 27 with the Redskins just a few hours after the start of free agency.
With Tennessee last season, he had a career-high 8½ sacks. He has 24 sacks in seven NFL seasons since the Titans drafted him in the first round out of the University of Tennessee in 2002.
Last year in another case, Haynesworth agreed to 30 days probation to divert a ticket for driving 103 mph in a 70 mph zone.
