(2) The display of a
green arrow on a traffic-control signal is a direction to a driver facing it
that opposing traffic has been stopped to enable him or her to proceed, or
that traffic does not conflict with his or her proceeding, in the direction
indicated by the arrow; and, where the arrow has not come into operation, the
display of a circular green signal, alone, is a direction to a driver facing
it that he or she may make the turn that would otherwise be indicated by the
arrow, but only if the movement can be made with safety, in the face of
oncoming traffic.
