Roy Stilling gurgled happily, sounding much
like they were saying:

If a vehicle falls under the legal definition that allows it to bear the
designation "Ambulance" and does so, then it is legally an ambulance
and entitled to various legal privileges that don't apply to ordinary
vehicles.

So a shiny black van, driven by a man in a black suit & black tie, and
bearing "Private Ambulance" in small gold letters on the bonnet, falls
into the same legal category as a battenburg-bedecked Merc Sprinter with
a paramedic on board?
