County courts are hereby authorized to promulgate rules and regulations, in accordance with the provisions of chapter twenty-nine-a of this code, governing (1) the movement, regulation or control of vehicular or pedestrian traffic on property owned by or leased by such county courts, or (2) the regulation or control of vehicular parking on such property. It shall be unlawful for any person to violate any such rule or regulation, if a sign or marker giving reasonable notice of such rule or regulation is conspicuously posted or present. The content of any such sign shall be sufficient if it merely gives notice of what is or is not permitted such as "no parking," "no left turn," "twenty miles per hour," etc.

It is further hereby provided that any person violating any such rule or regulation shall be guilty of a misdemeanor, and, upon conviction thereof, shall, unless another penalty be otherwise prescribed, be fined not less than $5 nor more than $25 for each offense. Justices of the peace of the county in which the violation occurs shall have jurisdiction of any such offense, and where the violation occurs within the corporate limits of a municipality, the mayor's court or police or municipal court of such municipality shall have jurisdiction thereof, concurrent with the justices of the peace of the county in which such municipality or the major portion of the territory thereof is located.
