At an intersection, what does a police officer's directions overrule?

A police officer's directions at an intersection hold authority over road signs and give way rules. This means that if a police officer is directing traffic, their instructions take precedence over any posted signage or established traffic rules that typically govern vehicle movement. This is crucial for ensuring safety and smooth traffic flow, especially in situations where the normal rules might lead to confusion or potential hazards.

Under normal circumstances, road signs and give way rules dictate how vehicles should behave at intersections to prevent collisions and ensure safe navigation. However, a police officer may be positioned to manage traffic specifically during unusual circumstances, like an accident or a special event, where the usual rules might not apply effectively. Thus, following the officer's directions is essential for all road users to adhere to, regardless of the usual signage or rules that would typically be in effect.
