Section 340.20. The plea

1.    Except as provided in subdivisions two and three, the provisions
  of  article  two  hundred  twenty,  governing  the  kinds  of  pleas  to
  indictments which may be entered and related matters, are, to the extent
  that  they  can  be so applied, applicable to pleas to informations, and
  changes of pleas thereto, in local criminal courts.
    2.  A plea to an information, other than one  against  a  corporation,
  must be entered in the following manner:
    (a)    Subject  to  the  provisions  of  paragraph  (b),  a plea to an
  information must be entered orally by the defendant in person unless the
  court permits entry thereof by counsel upon  the  filing  by  him  of  a
  written  and  subscribed  statement  by  the defendant declaring that he
  waives his right to plead to the information in person  and  authorizing
  his  attorney  to  enter  a  plea  on  his  behalf  as  set forth in the
  authorization.
    (b)  If the only offense or offenses charged are traffic  infractions,
  the  procedure  provided  in  sections  eighteen  hundred five, eighteen
  hundred six and eighteen hundred seven of the vehicle and  traffic  law,
  relating  to  pleas  in such cases, is, when appropriate, applicable and
  controlling.
    3.  A plea to an information against a corporation must be entered  by
  counsel.
    4. When a sentence is agreed upon by the prosecutor and a defendant as
  a  predicate  to  entry of a plea of guilty, the court or the prosecutor
  must orally on the record, or in writing filed with the court, state the
  sentence agreed upon as a condition of such plea.
