The Council of the Borough of Ligonier of the County of Westmoreland
and Commonwealth of Pennsylvania finds as a fact that the operation
of an engine brake on a motor vehicle with an internal combustion
engine not equipped with the proper exhaust mufflers, so as to create
an excessive noise through the use of said engine brake, adversely
affects the public health and, therefore, is a nuisance in fact.
No vehicle powered by an internal combustion engine shall be
operated on the streets, roads, alleys or highways within the Borough
of Ligonier utilizing, in said operation, an engine brake without
exhaust mufflers or with defective or modified exhaust mufflers permitting
excessive noise to be created by said motor vehicle.
