Interestingly, what we see as "tram signals" apply to buses in most
European countries too.

In UK law the white light signals are traffic lights that apply only to
trams, as opposed to the red/amber/green ones which apply to road
traffic other than trams.

Going past a horizontal white light signal is the same in law as a bus
driver going through a red traffic light, and carries the same penalties.

Statutory Instrument 2002 No. 3113 refers.
