1. A speed monitoring system for a motor vehicle 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; and
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.

Abstract
A motor vehicle speed monitoring and ticketing system visually indicates when a speed limit has been exceeded. The driver is required to register as a violator before the indicator can be de-energized.
