The former NBA player was also charged with driving across a dividing section and without a valid license as well as giving police false information.
Orange County prosecutors filed misdemeanor charges against Rodman for the accident that took place on Interstate 5 in Santa Ana, California.
According to the AP, Rodman’s SUV was headed north in a southbound carpool lane at about 12:30 a.m. The incident forced a vehicle to swerve into a diving wall to avoid crashing into his car.
Paul Meyer, his lawyer, said the incident occurred because of a poorly signed exit ramp.
Rodman could face two years in a county jail if convicted.
