Section 1808. Effect of stay order on appeal from judgment of conviction of an offense under this chapter

(a)  When  an  appeal  is  taken  to  an
  intermediate  appellate court from a conviction of an offense under this
  chapter resulting in the suspension or  revocation  of  the  defendant's
  motor  vehicle  operator's  license,  and a stay of execution is granted
  ordering reinstatement of such license during the pendency and until the
  determination of such appeal, service of a certified copy of  such  stay
  order  by  mail upon the commissioner of motor vehicles shall be binding
  upon the commissioner; and during a period of ninety days from the  date
  such  stay  order  was  granted,  or until such appeal is determined, if
  sooner than ninety days, such commissioner shall be stayed  from  taking
  any  proceedings  under the vehicle and traffic law to suspend or revoke
  such license on account of such conviction; and such order shall contain
  appropriate provisions to that effect.
    (b) For good cause shown, such stay may be extended by the  court,  in
  its  discretion,  for additional periods not to exceed ninety days each;
  such extension order or orders, when served  upon  the  commissioner  of
  motor  vehicles  in the same manner as the original stay order, shall be
  binding upon him to the same extent as the original stay order for  such
  additional period or periods.
    (c)  A  stay  order or orders issued pursuant to section 460.50 of the
  criminal procedure law which purport to reinstate a license  during  the
  pendency  of  an appeal from a conviction resulting in the suspension or
  revocation of a license shall, for the purposes of  such  reinstatement,
  be deemed to be issued in accordance with the provisions of this section
  and the ninety day stay period authorized by this section shall apply.
