Traffic fines are so abused as to be a medieval toll on bridges. All over this country traffic enforcement is abused to raise revenue by local governments. When I lived in Texas in the late 90’s is was recognized as a huge problem. Along I-10 in West Texas there were small 1 horse towns (less that 50 people total) that had mayors and judges with 6 figure salaries, all supported by fines. Texas made a stab at fixing the problem by enacting a law that all traffic fines go directly into a state fund, not the locality in which they were issue, to remove the conflict of interest.
No kidding! I got pulled over there while driving a rental car. My crime? 56 MPH in a 55 zone!
