I just watched a video from my old dept, WSP. At this time, they will NOT be making stops to check travel status. Each state could be different. In Europe, they do stop you. There are reports that some are pretending to be LEOs (Law enforcement officers)
For those with FB. The video explains how you can tell a WSP trooper car, marked or not. There are a very few that do NOT have no exterior markings, spot lights, push bars, etc.
