Final answer:
You should follow the directions of a police officer or traffic control device, including keeping to the right, as they have legal authority over traffic management. There are exceptions for emergencies where breaking traffic rules might be justifiable. Drivers must always consider safety and legality in their actions.
Step-by-step explanation:
When given directions by a police officer or a traffic control device, it is generally required by law to comply, including keeping to the right when instructed to do so. In the context of a police officer issuing commands, their authority is limited to law enforcement-related tasks. Asking a driver to do something like mow their lawn would exceed the scope of their authority. Similarly, traffic control devices, which include road signage and traffic lights, are legally binding instructions for managing the flow of traffic to ensure safety and efficiency on roads.
There are exceptions to these rules, such as when an emergency situation arises. For example, running a red light at 4 am with a pregnant woman in labor in the vehicle could be justified if it's necessary to get to the hospital promptly and safely, and no other cars are around.
However, it is crucial for drivers to be aware that such actions could still be illegal and might require explaining the circumstances to law enforcement officers. In all situations, drivers need to use their judgment and prioritize safety while remaining aware of the legal expectations and responsibilities they hold.
