Why do police vehicles block the roadway when making a car stop? Why can the officers move their unit when I tell them to do so?
Police officers will create a safe zone to make their approach on foot by angling their police unit slightly into traffic. Until they are done with their traffic stop, their police unit is left in place. Officers, depending on the type of traffic stop, and if it is safe to do so, may move their unit upon a request by a citizen. However, if the traffic stop is not safe, then any citizen making a request will have to wait unit the traffic stop is completed.
