I was calm, but confused as to why he had stopped me since he had been following me on his motorcycle close behind me for about 5 blocks. He said that he ran my plates and he wasn't sure what was showing up. Once I showed him the DMV paperwork he said that it made sense now and that was it.
It was a quick stop, about a minute or two, and yeah, it felt good after it was over since I had everything correct and under my name and there were no problems
