Yeah George, all this stuff varies widely from state to state. One thing they do in Connecticut is for infractions, you can ONLY get a trial in front of a magistrate and if you or the States Attorney's Office don't like the outcome, you can make a motion to the court for a "Trial de Novo" in front of a judge.
Also in Connecticut, if you are given a ticket for an INFRACTION (minor ticket) you DO NOT have the option of a jury trial.
A long time ago, I was given a high dollar speeding ticket, I went in front of a judge and said I wanted a trial by jury since speeding at that level (at the time over 70 mph in a 55 zone, the officer said I was going 72 but he confused me with another car since it was 4:30 p.m. in HEAVY traffic on the Friday Memorial Day weekend) was an automatic court appearance, not an infraction (a mail-in ticket). I had photographs of the heavy traffic and figured I had a great chance to be found not guilty by a jury.
When I requested the jury trial, the prosecutor said, "Your honor, I will substitute charge the defendant with unreasonable speed which is an infraction which means he does not qualify for a jury trial."
Curses, foiled again

I was found guilty by a judge because you can't defend yourself against a lying police officer (no offense George but this guy was an outright liar).
