My question involves a traffic ticket from the state of: California
I was pulled over driving 70 in a 70mph zone. (The officer wrote 65 on the ticket for some reason) and got pulled over for an unsafe lane change.
It was a two lane freeway and I saw some headlights come from far away and pull up to my bumper about a minute or two after I cut lanes. This happened to be the CHP.
What he said was, I cut to the left lane and caused him to brake hard. I told him that I flashed my blinkers for well over 100 feet and saw that there was no car to my left. There indeed was no car and he is in fact making everything up. However he wouldn't take no as an answer and pretty much forced me to sign the ticket since I would probably be in bigger trouble if I didn't sign.
He also admitted that he saw me blink my turn signals, i have a feeling that he was going well over 70 mph and by cutting to the left lane on a two lane road I may have unknowingly pissed him off because he was blocked. He did not have lights and sirens on or anything so I didn't know he was a police officer when he was approaching really fast to the back of my car. I thought it was just a person trying to speed.
Can anyone help on how to fight this case? I think his patrol car camera may actually prove me innocent since you will see me merging onto the left lane way before the officer is even near my car. But what are my chances of even being able to see that footage or use that footage in court?
