Yes. NC Law G.S 20-156 requires vehicles to yield to emergency vehicles when the emergency vehicle is giving a warning signal, such as emergency flashing lights, and an audible device, such as a siren. In addition to yielding to emergency vehicles, NC Law G.S. 20-157(f) (Move Over Law) requires motorists to move over one lane when an emergency vehicle is stopped on the side of a roadway. In the event the motorist cannot move over, they shall slow and be prepared to stop.
