I Charlotte, NC they are "not negotiable". Your ONLY two choices are pay the fine or prove you were not driving the car and give the name of the person that was. Malfunctioning cameras are not a defense.
Comming soon to a city near you...
That doesn't sound right to me -- you can always request a Jury Trial (6th Amendment) or appeal (1st Amendment). Can you link the applicable code?
I am not saying you are wrong -- the very EXISTANCE of a thing called an "infraction" is prima facie unconstitutional. I just want to see how bad the undermining of our rights has gotten.
If what you say is correct, then a ticket coming from a red light camera is the only criminal process in America that does not have the right of appeal. Do you have a source?
