What is the correct action a driver must take if they have already entered an intersection and an officer raises their arm vertically?
A)Stop immediately, regardless of their location in the intersection.
B)Continue their path through the intersection without stopping.Correct
C)Stop only if it can be done safely without obstructing traffic.
When an officer raises their arm vertically, all road users approaching the officer are required to stop, except drivers who cannot do so under sufficiently safe conditions. If this signal is given at an intersection, it will not require drivers who have already entered it to stop, since signals are given with sufficient time and the action of stopping inside the intersection, obstructing passage, would not be correct.
