Artie Lange just pled not guilty to driving under the influence.
As we first reported, Lange was arrested on Friday after rear-ending another car in Toms River, NJ. Lange's lawyer says he passed an alcohol screening test after the crash -- but cops thought he was under the influence anyway and requested a urine sample. The results of that test aren't in yet.
Artie is due back in court on Aug. 26.
