Sec. 1. The judges of the municipal courts of the state in counties now or hereafter having a population of 100,000 or more according to the latest or each succeeding federal decennial census, shall have authority to establish violations bureaus from the personnel of the court for the purpose of assisting said courts in the disposition of complaints of violations of the traffic ordinances, rules and regulations of the municipalities in which said courts are constituted, and shall have authority to adopt rules and regulations for the operation of said bureaus. The personnel of the court violations bureaus shall be required to post bond in such amount as said judges may deem advisable.

The said municipal judges who hear traffic cases shall designate the specified offenses under the traffic ordinances of their city and the state traffic laws in respect to which forfeitable bonds may be accepted by the traffic violations bureau in satisfaction thereof, and shall specify by suitable schedules the amount of such bonds for first, second, and subsequent offenses, provided such bonds are within the limits of the respective fines declared by such law or ordinance, and shall further specify what number of such offenses shall require appearance before the said municipal judges. In all such cases all notices and papers used in relation thereto shall advise all alleged violators of their right to a trial by jury.
