As non-primary, you are responsible for blocking all roads in every direction. You are authorized to set up spike strips if requested by the lead unit or scene command, be sure to inform all officers where the spike strips are and place your vehicle so that the suspect cannot avoid spike strips. Once the Suspect flees from the scene whichever way the suspect or suspect’s travel units will then split and go after each suspect. If one goes south and one goes north then all units south will go after the suspect heading south, and all units north on the scene will travel after the suspect heading north. Be advised that the unit behind the suspect then becomes primary and the second unit will relay streets and directions of travel.
