My question involves a traffic ticket from the state of:Los Angeles California
So I was driving down a highway and a saw a police with a radar and slowed down. He then proceeded to pull me over and cited me and told me that when he's saw my car he assumed I was going 70 mph but the radar gun clocked me at 72mph. But I was going he appropiate speed limit. Today I passed by the same highway and saw the speed limit was 50mph. So it mean he didn't know the speed limit of the highways. Is there any way I can fight and win the ticket !?
Btw I complied but I know for a fact I was driving safe and the appropriate speed as the traffic.
