If a policeman signals you to stop at an intersection with a green traffic light, what should you do?

When a policeman signals you to stop, their authority takes precedence over traffic signals, including a green traffic light. This is crucial for maintaining safety and order on the roads. Law enforcement officers are trained to manage traffic and respond to situations that may not be apparent to an average driver, such as emergencies or the need to direct traffic for a specific reason.

Following the policeman's signal ensures that you comply with the law and contribute to the safety of all road users. In scenarios where there is conflicting information from traffic signals and police instructions, the directive from the officer must always be followed.

Understanding this will help in recognizing the importance of police authority and maintaining safe driving practices, regardless of what traffic lights indicate.
