Taken relatively close to the ambulance's front during a run. This way the light bar on the roof and the wig-wag is shown. It even shows the small blue light on the dashboad. "AMBULANCE" appears in mirror writing ("ƎƆИАᒧUᗺMA"), so the writing appears right way round in <a href="https://en.wikipedia.org/wiki/rear_view_mirror" class="extiw" title="en:rear view mirror">rear view mirrors</a> of vehicles ahead of it in traffic.
