This article shall be known and may be cited as the "Mount Joy
Borough Engine Brake Ordinance."
The Borough Council of the Borough of Mount Joy, Lancaster County,
Pennsylvania, finds, as a fact, that the operation of an engine brake
on a gasoline- or diesel-powered motor vehicle not equipped with exhaust
mufflers or equipped with defective or modified exhaust mufflers so
as to create excessive noise through the use of said engine brake
adversely affects the public health, safety and welfare of the residents
of Mount Joy Borough and, therefore, is a nuisance in fact.
No gasoline-powered or diesel-powered motor vehicle shall be
operated on any street, road, alley or highway within the Borough
of Mount Joy listed below utilizing, in said operation, an engine
brake, without exhaust mufflers, permitting excessive noise to be
created by said motor vehicle using the engine brake.
This article shall not apply to emergency driving.
