When might an officer need to make traffic lights flash red?

An officer may need to make traffic lights flash red to draw attention to an accident. This action serves a critical purpose in alerting drivers to a disruption in the normal flow of traffic, particularly when an accident presents a potential hazard. Flashing red lights indicate that drivers should come to a complete stop and approach with caution, allowing for emergency vehicles to navigate the scene safely and for responders to assist those involved in the accident.

This procedure helps manage traffic and ensures safety for both the individuals involved in the accident and other road users. The use of flashing lights is an established protocol during emergencies, making it a necessary tool for law enforcement in specific situations where visibility and safety are compromised.
