I agree with Sometimes Miss as far as discussing it with the prosecutor. He is really your best hope in eliminating the ticket and don't hesitate to tell him you have been unemployed for some time and this will cause an undue hardship. You can explain that you haven't had a ticket in decades because you are a safe an conscientious driver.
Now for the bad news - Judges in traffic court are not real judges in my opinion. They are cashiers. They work for the city and this is a revenue source for the city, plain and simple. You are guilty unless you can prove yourself innocent. I know because I have been there. If it reaches the "judge" ask for legal guidance and a court appointed attorney as you can't afford one. Be humble when you speak and you MIGHT get it dropped. Good luck.
