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.
