Attorney Michael Grasso entered the plea Tuesday in Toms River Municipal Court.
Grasso said Lange passed an Alcotest screening for alcohol after the accident.
Police say officers assessed Lange as being under the influence based on their physical observations and required him to provide a urine sample. Results have not been received.
Lange, a regular on radio's "Howard Stern Show," is scheduled to appear in Municipal Court on Aug. 26.
