Which of the following must you obey over the others?

When navigating traffic, following directives from a police officer takes precedence over all other signals and signs. This is because law enforcement officers have the authority to manage traffic and enforce the law directly on the road. Their instructions may vary based on specific situations, such as directing traffic at an accident scene or a community event, where the normal road signals may not apply or be overridden for safety reasons.

While signals like a steady red light, flashing red light, and stop signs are important traffic controls that inform drivers when to stop, yielding to a police officer's instructions ensures compliance with the law and promotes overall safety. In scenarios where traffic lights or signs conflict with an officer's directive, prioritizing the officer's guidance is crucial to maintaining order on the road and responding to the dynamic nature of traffic situations effectively.
