Council may, from time to time, designate places upon and along the streets and alleys in the Borough where, for a period of not more than 90 days, specific traffic and/or parking regulations, prohibitions and restrictions shall be in force and effect, and shall designate those locations by proper signs and markings. Those regulations, prohibitions and restrictions shall be effective just as if they had been specified in this chapter. No person shall drive or park a vehicle in violation of any such regulation, prohibition or restriction, and no person shall move, remove, destroy or deface any sign or marking elected, posted or made by authority of this section. Any person who violates any provision of this section shall, upon conviction, be liable to the penalty set forth in the law or elsewhere in this chapter for a violation of that nature and, in case of a violation for which no specific penalty is set forth in the law or elsewhere in this chapter, to a fine of $25 and costs, provided that the purpose of this section shall be to allow for the cost and experimental determination of the feasibility and desirability of permanent changes in the ordinances of the Borough relative to traffic and parking.
