My question involves a traffic ticket from the state of: North Carolina

On June 11th, I received a citation for failure to yield to steady read light at intercession. I zoned out while driving and collided with other vehicle. It was totally my fault. I've had two continuances because insurance claims are still being processed. The 2nd time I appeared in court I was asked to present some documents. What was I suppose to have that my insurance company didn't tell me? Also my last court date is Sept. 14th, I'm very nervous, what should I expect and is it possible for me to defend myself?
