The New Jersey Turnpike Authority became aware of the necessity for vehicle noise emission regulations in early 1973. A consultant was engaged to prepare these regulations, and in June 1974, a public hearing was held on the proposed noise regulations. Subsequently, on July 23, 1974, the authority adopted, in its final form, the vehicle noise emission regulation. All necessary requirements of the New Jersey Administrative Code were followed. In deference to some of the arguments presented by the Motor Trick Association, the stationary test and visual inspection tests were to become effective on January 1, 1975, and the pass-by test to become effective October 1, 1974. During August and September, an extensive program was conducted whereby noise levels were measured and truckers were informed of the results in order that corrections could be made. The Traffic Engineering Department was assigned the responsibility of enforcement. Special training was required for the noise enforcement personnel. The authority sought to set a minimum fine for noise emission violators, but the statutes governing fines for traffic violations on the turnpike did not permit this. The authority is presently trying to change the regulations pertaining to fines. Sites were selected with concern for the safety of the equipment operating personnel, concern for the position of the state police intercept vehicle and the distance available to pull over a violating vehicle, and concern for the nature of the engineering features and the sound-reflecting surfaces within the measurement site.
