When can a driver disregard a signal from a police officer directing traffic?

A driver must adhere to a police officer's signals directing traffic at all times, regardless of the situation. Police officers are authorized to manage and direct traffic for various reasons, and their signals take precedence over traffic signals and other indications. Therefore, even if an emergency vehicle is approaching or there is a conflict with a traffic signal, drivers are required to follow the officer's instructions. This ensures safety and order on the road, as police officers are positioned to manage traffic in real-time scenarios that may not be evident from traffic signals alone. Ignoring an officer's signal can lead to confusion and potentially dangerous situations on the roadway.
