Lawson was charged with driving after consuming alcohol, violating a local noise ordinance and driving with a suspended or revoked license. Investigators said it's unclear why his license was invalid.
Police say Lawson signed a written promise to appear in court. That court date is set for July 8.
Lawson was one of three North Carolina players who declared for the 2008 NBA draft. He has not hired an agent, meaning he could return to school for his junior season.
