<human>: Can you provide a brief overview of the text?

In December of last year, I was rear-ended on the highway. I had been trying to merge right from as soon as I saw the merge signs, as the lane I was in was going to close due to construction. This was right after Christmas, so there was a lot of traffic. There were no opportunities to get over. I was gradually slowing down the entire time, as I knew that the lane would close soon. A pick-up truck had been following me closely since before the construction zone, and continued doing so the entire time I was slowing down. I was unable to merge, and came to a complete stop, entirely within my lane. I was hit moments later by the pick-up truck, on the right rear side of my vehicle.

I was shaken up by this, as I had never been involved in a collision while I was driving, and also because my girlfriend was a passenger. Neither of us were injured, but I was still very concerned about her. Both drivers were instructed to move our vehicles before an officer replied. I gave a statement to the officer who responded to the scene of the crash. My statement was apparently unclear. The driver of the truck that hit me was able to convince the officer that the collision was my fault. According to the traffic report, I "darted" in front of the truck, which was (again, according to the traffic report) in the right lane. This is not what happened, as I was at a complete stop, and the truck was traveling in the same lane as I was. 

I was cited for an improper lane change, and now have to go to traffic court on Tuesday. I have pictures that show my car within the lines of the left lane, and the truck behind me, halfway into the right lane. I am also planning on bringing a letter from my girlfriend detailing what happened (though I know she is not an impartial witness). Will this be enough to get a not guilty verdict? Is there anything I should say, besides the facts?
<bot>: I was wrongfully cited for an improper lane change, and I have evidence that shows I did not change lanes at all.
