    * § 24-241 Emergency signal devices. (a) No person  shall  operate  or
  use  or cause to be operated or used any emergency signal device, except
  on an authorized emergency vehicle when such vehicle is in  the  act  of
  responding  to  an  emergency;  provided  that  such device shall not be
  operated for a period of time longer than is  necessary  to  respond  to
  such  emergency. Notwithstanding the foregoing, such a device on a motor
  vehicle shall be lawful if designed and used solely as an audible  motor
  vehicle  burglar  alarm  in  accordance with section 24-238 and a device
  attached to a vehicle for the purpose of providing  an  audible  warning
  when  the  vehicle  is  backing  up  shall  be permitted even though the
  audible warning may consist of a gong or bell sound.
    (b) No person shall operate or permit  to  be  operated  an  emergency
  signal  device  installed  on  an authorized emergency vehicle that when
  operated at the maximum level creates a sound  level  in  excess  of  90
  dB(A)  when  measured at a distance of fifty feet from the center of the
  forward face of such vehicle. Within one year after the  effective  date
  of  this  subdivision  and  every two years thereafter, emergency signal
  devices installed on authorized emergency vehicles shall be  tested  and
  certification  shall be submitted, in a form approved by the department,
  that such devices meet the standard set forth in  this  subdivision  for
  operation  at  maximum  level. Notwithstanding the foregoing provisions,
  where compliance with the provisions of this subdivision would create an
  undue hardship, the owner or operator of an authorized emergency vehicle
  may submit a plan to the commissioner for emergency  signal  devices  to
  meet  the  standard set forth in this subdivision within two years after
  the effective date of this subdivision. Such  plan  shall  be  submitted
  within  one year after the effective date of this subdivision in lieu of
  the  required  certification.  This  subdivision  shall  not  apply   to
  authorized  emergency vehicles of the police department, fire department
  or authorized emergency vehicles responding to medical emergencies.
