This question evaluates the driver's understanding of the prioritization of signals in traffic management. In British Columbia, Canada, as well as in other regions, a police officer's instruction takes precedence over traffic lights and road signs. Specifically, drivers must comply with the directions given by law enforcement officers even when these directives contradict posted traffic signals. This rule is crucial for maintaining order and safety in scenarios where the standard traffic signals are not adequate, due to accidents, heavy traffic congestion, or construction sites. Thus, candidates must recognize and apply the hierarchy of authority in traffic control according to local regulations.
