Korean Driver's License Practice Test 2025 – Complete Exam Prep

When a police officer is directing traffic, that officer has the authority to override the normal function of traffic signals. This means that regardless of what the traffic lights indicate, drivers and pedestrians must follow the officer's signals and commands. The role of the police officer in this context is to manage the flow of traffic, especially in situations where normal traffic control measures, such as lights, may not be sufficient or could lead to confusion, such as during accidents, parades, or other special events.

By directing traffic, the officer ensures safety and order on the roads, making real-time decisions based on the specific circumstances at that moment. Therefore, anyone in the vicinity must defer to the authority of the police officer over any existing traffic signals.

Traffic lights serve as automated guides for road users, but in a situation where a police officer is present and actively managing the flow, the signals are no longer the definitive authority.
