Claim 10

The system in accordance with claim 8 wherein said locking means comprises: a. a bracket mounted within said motor vehicle; b. a movable latch in said bracket in the path of said lever, said latch adapted to permit said lever to pass thereover as said lever is placed in said second position; c. biasing means for urging said latch into the path of said lever after said lever has been passed thereover to retain said lever on said bracket; d. means for withdrawing said latch from the path of said lever when said motor vehicle attains a predetermined speed to permit said lever to be returned to said first position.

Claim 11

The system in accordance with claim 9 wherein said means comprises: a. a fifth circuit closing element adapted to be opened or closed by said movable indicator; and b. a solenoid mounted on said bracket in circuit with said fifth circuit closing element adapted to withdraw said latch from the path of said lever when said circuit closing element is closed, and to return said latch into position when said circuit closing element is open.

Claim 12

In combination with a motor vehicle, a speed monitoring and ticketing system comprising: a. a speedometer fixedly mounted within said motor vehicle having a calibrated scale and a movable indicator adapted to visually indicate the speed of said motor vehicle by changing its position on said scale; b. a source of electrical energy within said motor vehicle; c. a first circuit closing element adapted to be opened and closed by said movable indicator; d. a second circuit closing element adapted to be opened and closed by said movable indicator, said first and second circuit closing elements forming a first group; e. a third circuit closing element adapted to be opened and closed by said movable indicator; f. a fourth circuit closing element adapted to be opened and closed by said movable indicator, said third and fourth circuit closing elements forming a second group, said first group being associated with a low speed limit and said second group being associated with a high speed limit; g. a warning circuit energized by said source of electrical energy when said first or said third circuit closing element is closed; h. a violation indicator mounted externally on said motor vehicle adapted to give an external indication of a speed limit violation; i. means for energizing said violation indicator by said source of electrical energy in response to the closing of said second or said fourth circuit closing elements, said means remaining energized when said circuit closing elements are therewith opened; j. a selector means having a first and a second position, said first group of circuit closing elements controlling said warning circuit and said violation indicator when said selector means is placed in said first position and said second group of circuit closing elements controlling said warning circuit and said violation indicator when said selector means is placed in said second position; k. circuit breaking means in circuit with said violation indicator adapted to de-energize said violation indicator in response to a transmitted signal of a predetermined frequency; l. a signal transmitting means positioned at predetermined locations along a roadway; and m. means for activating said signal transmitting means to activate said circuit breaking means thereby de-energizing said violation indicator.
