The text of Engrossed 1995 Assembly Bill 438 consists of the following
documents adopted in the assembly on January 18, 1996: Assembly Substitute
Amendment 2 as affected by Assembly Amendments 1, 2, 3 and Assembly
Amendment 4 (as affected by Assembly Amendment 1 thereto).
Content of Engrossed 1995 Assembly Bill 438:
Current law prohibits motor vehicle operators from using a radio or other
electric sound amplification device (sound-producing device) that is audible 75 or
more feet from the vehicle unless the device is being used to request assistance or
warn of an unsafe condition. Exceptions apply for warning horns, authorized
emergency vehicles, public utility vehicles, antitheft alarms and vehicles used in
advertising, special events, processions or assemblages. Improper use of a
sound-producing device may result in a forfeiture of not less than $20 nor more than
$40 or, for a 2nd or subsequent conviction within a year, a forfeiture of not less than
$50 nor more than $100.
This bill doubles the minimum and maximum forfeiture amounts that may be
imposed for the improper use of a sound-producing device. The bill also permits any
city, village, town or county to enact an ordinance providing that improper use of a
sound-producing device occurs if the sound-producing device is clearly audible 50
or more feet from the vehicle.

This bill imposes upon the owner of a vehicle liability for improper use of a
sound-producing device of the vehicle, regardless of whether the owner was
personally using the sound-producing device. Any member of the public who
observes the improper use of a sound-producing device may prepare a written report
and deliver the report to a traffic officer. The traffic officer is required to investigate
the violation and may prepare a traffic citation for the violation. Any traffic officer
employed by the issuing authority may serve it upon the owner of the vehicle.
The owner of the vehicle has a defense to liability for the violation if the vehicle
had been stolen at the time of the violation or if the owner provides the traffic officer
with the name and address of the person who was operating the vehicle or who had
the vehicle under his or her control at the time of the violation and sufficient
information for the officer to determine that probable cause does not exist to believe
that the owner committed the violation. Lessors and dealers of vehicles have similar
defenses.
A vehicle owner found liable for a violation is subject to the same forfeiture that
applies to a vehicle operator who improperly uses a sound-producing device. The
operating privilege of a person convicted of a violation may not be suspended or
revoked, and no demerit points may be recorded against the person's driving record.
The bill also allows any city, village, town or county, by ordinance, to authorize
a law enforcement officer to impound any sound-producing device used in the
commission of a violation. The bill also allows a vehicle to be impounded for up to
5 days to remove the offending sound-producing device, if the device can not easily
be removed from the vehicle. Impoundment of a vehicle or device only applies if the
violator is the owner of the sound-producing device and has 2 prior convictions in a
3-year period of the prohibition against the improper use of a sound-producing
device by a motor vehicle operator or of any local ordinance prohibiting excessive
noise.
The violator is responsible for the costs of impounding the vehicle or
sound-producing device, which must be claimed by its rightful owner after
disposition of the matter, including the payment of any forfeiture imposed. If the
sound-producing device or vehicle is not claimed within 90 days, the city, village,
town or county may dispose of it.
If the violator has 3 prior convictions in the 3-year period, the city, village, town
or county may, by ordinance, authorize the law enforcement officer to seize any
sound-producing device used in the commission of the violation. The
sound-producing device is subject to forfeiture in the same manner as provided
under state law for property realized through the commission of a crime.
For further information see the state and local fiscal estimate, which will be
printed as an appendix to this bill.
