The Traffic Violations Bureau so established is hereby authorized to dispose of violations of traffic laws, ordinances, rules and regulations designated by the court, except the offenses constituting the traffic infraction of speeding or a misdemeanor or a felony, by permitting a person charged with an offense to appear within a specified time at the Traffic Violations Bureau, either in person or by written power of attorney in such form as prescribed herein, by paying a fine and, in writing, waiving a hearing in court, pleading guilty to the charge and authorizing the person in charge of the Bureau to make such a plea and pay such a fine in court. Acceptance of the prescribed fine and power of attorney by the Bureau shall be deemed complete satisfaction for the violation, and the violator shall be given a receipt which so states. If a person charged with a traffic violation does not answer as hereinbefore prescribed within a designated time, the Bureau shall cause a complaint to be entered against him forthwith and a warrant to be issued for his arrest and appearance before the court. Any person who shall have been, within the preceding 12 months, guilty of a number of parking violations in excess of such maximum number as may be designated by the court, or of three or more violations other than parking violations, shall not be permitted to appear and answer to a subsequent violation at the Traffic Violations Bureau, but must appear in court at a time specified by the Bureau.
