Police photo radar van took a picture?

I was driving on the right side of the road. The speed limit is 35mph. I was driving 30 because usually there is a photo radar police van. There was a Honda accord driving really fast behind me. The driver that was driving behind me didn't know that there is a police van. He was driving more then 40mph. What happened is the driver was on the left side and when he realized that there a photo radar van he pressed on his breaks and he was right next to me on the left side. My van was way taller and longer then his car and the police van took a picture of me and i am not sure if he got the speeding car because the driver was on the left side right next to me. Are they going to give me ticket because they had a perfect shot of my vehicle and i am not sure if they are going to be able to see the other car. I was driving way slower then the speed limit because i drive on that road every day and i already know about the police van being there.
