Hairston was charged with speeding and reckless driving on Sunday afternoon. Police pulled him over for driving a 2008 Acura TL at 93 mph in a 65 mph zone outside Salisbury, N.C.
After this latest traffic citation, North Carolina coach Roy Williams suspended the junior indefinitely late Sunday night.
This is the third time Hairston has pulled over and cited for traffic violations since May, all three times he was driving different vehicles, none of which belonged to him.
Hairston was initially charged with marijuana possession and driving without a license on June 5, but those charges were dropped earlier this month.
Hairston averaged a team-high 14.6 points per game at the end of his sophomore year.
