Final answer:
Drivers are required to follow the instructions of law enforcement officers even when these instructions go against traffic signs or signals. Police officers have the authority to direct traffic to ensure public safety in various scenarios.
Step-by-step explanation:
Drivers must follow the commands of law enforcement officers even if it contradicts a sign or signal. Police officers, as representatives of governmental authority, have the discretion to override traffic control devices under specific circumstances to maintain safety or respond to an emergency. For instance, an officer can direct traffic at an intersection, effectively negating the usual rules associated with traffic lights and signs. The legitimacy of their authority in traffic control illustrates how citizens respond to authority in everyday life. This authority is based on laws and regulations that empower police officers to maintain public safety, which can include directing traffic in a manner that contradicts posted signs or signals.
