My question involves a traffic ticket from the state of: Colorado

Hello all,

I was involved in an accident that took place on a Colorado interstate highway during a traffic jam. I was driving in the second slow lane from the left in stop n go traffic. I was hit by another vehicle that came from the far right lane. We were going about 10-20 MPH. The vehicle hit my right mirror and broke it of and dented the panel just in front of the doors side panel below my mirror. The driver of the other vehicle tried to gun around in front of me which resulted in what I stated before. The damage to his f150 was on the driver side door where he hit my mirror. (I got some pics, barley but good quality)

I pulled over on to the shoulder of the highway to an infuriated driver who was cursing and accusing some such rubbish. I noted another traffic accident approximately 100 meters in-front of us. A female officer who was attending the other accident came and inquired to our disposition. She asked the other driver what happened after she told us to calm down. Then she asked me if he hit me in my lane and I said yes, that's when she called for another officer to assist us in our situation. The male officer came within 10 mins and requested license and registration from us both and gave us a form to fill out. The officer directed us to move from the shoulder lane of the highway to the shoulder lane of the on ramp about 20 meters ahead as he stopped on ramp traffic and directed us. After the officer talked to the other driver he asked me what happened and I told him the driver hit us in our lane(my daughter was in the vehicle). He asked me if I saw the other driver and I said yes. The officer wrote me the citation he said because I should have stopped and the other driver was past the half way point??. The guy didnt even signal to come over and the officer cited me?

Ok, so now The other drivers insurance company calls and the guy is trying to obtain damages and his insurance provider says he had the right of way because the officer directed him into my lain( which he wasn't present for the accident nor the female officer who was 100 metes ahead after we pulled onto the shoulder) After the officer exchanged our information he gave me permission to photograph the accident. I only got in 2 pics of the other drivers vehicle before he shouted the officer cited me for the accident and drove off.

Now that I have a court date coming up, I called the court to asked them how I request the citing officer be present at my case, they said I have to file a subpoena then to have the officer served? Is that true? I am also wonder how do I file a written noticed to obtain discovery? as well as when I go to court what laws should I show the judge that support the my case and show I was not negligent. Also how do I show what laws the other driver broke or was negligent about? and what do i tell my insurance company?

Thank you for any help and I apologize for my poor grammar!
