I seen a cop on the side of the road in the dark as I drove closer, when I passed him, I went over the center double yellow line. I wasn't sure what he was doing in the dark at night with his lights on so I thought he might be outside, and there were not any cars on the small road so I only "failed to maintain lane" at that time. After that he got me for a DUI. But can I possibly get the stop thrown out in any way? I have three witnesses in the car who saw I drove complete straight as I drove a good distance to that point. In addition, the cop never pulled out to get me as I was driving down the road before I got to him. I always maintained my lane prior to that point.
