I'm a 17 year old from California and I recently received a ticket for running a red light. The light was yellow when I went through, and I didn't accelerate so I would like to fight the ticket. When the cop came to my car he asked me if I had been "smoking tons of pot tonight". I couldn't believe it and told him I'd had none and that he could test me. After handing him my license and registration he had me get out of the car, then he searched me and checked my eyes. Despite having nothing on me and being sober he went and searched my car too, without my permission. He told me my car had smelled like it when he first walked up and seemed unconvinced and disappointed that he couldn't get me on more serious charges. There was also another officer with him, but he said nothing to me, just waited in the car.
1. Is this harrassment of a younger driver, to assume I am smoking pot with zero evidence?
2. I heard that cops rarely show up in court to contest, is this true?
3. Does it cost anything to contest the ticket in court, do I have anything to lose?
