If involved in car accident and wrongly ticketed, what to do in court?

I was going thru an intersection and light turned yellow, man turned in front of me to make a left turn. I hit him and spun around and hit 2 other cars. Cop ticketed me and said I sped up to avoid yellow lite. Wouldn't that mean he turned on a yellow? I was not asked at accident what happened, and was weak and kept blacking out. Cop left ticket at hospital for me. Also, insurance dropped me after 4 yrs., and claim I cxld them days before accident. I did not cxl and they have auto withdrawn for 4 yrs. They said they listened to a recording of me telling them to cxl. I told them to play the tape for me and they refused. My car is totaled and no coverage along with everyone else trying to get at me. How do I prove he is at fault? How do I protect myself? How do I defend myself? And do I have to file b.k.? I need help asap. Thank you.
