During an incident, when is it imperative to switch on hazard warning lights?

Switching on hazard warning lights immediately upon arrival at the scene of an incident is crucial for several reasons. Firstly, activating the hazard lights serves as a visual warning to other road users, indicating that there is a potential hazard ahead. This action can help prevent further accidents by alerting drivers to slow down or maneuver around the scene, especially in situations that could obstruct traffic flow.

Furthermore, using hazard lights as soon as you arrive allows you to communicate the urgency of the situation to other drivers without needing to leave your vehicle or take other actions that could distract from monitoring the incident. It helps establish a safe perimeter around the scene, which is important for the safety of all involved, including any individuals who may have been directly affected by the incident.

While calling for help, moving vehicles away, or considering nearby traffic are also important actions to take during an incident, the immediate activation of hazard lights serves as the first line of defense in preventing additional accidents and ensuring everyone's safety.
