Interstate, three lanes each direction, roadway rises for bridge over railroad tracks, local (Plymouth Township) officer parks in median just past bridge railings below level of highway surface, thanks to Michigan’s two tier speed law, especially dangerous for trucks in center lane, which is easy to do as this is a major suburban connector Interstate with traffic entering a quarter mile in either direction, radar may pass under commercial vehicle and take reading of car passing on the right. Also for some reason officer does not need to testify in person at local court, so charge will not be dismissed if officer is not present.
