Which strategies are effective for managing traffic around an accident scene?

Deploying cones and flares and redirecting traffic is critical for managing traffic around an accident scene effectively. Such actions create a physical barrier to ensure that vehicles do not inadvertently enter a dangerous area, protecting both responders and motorists. Flares serve as a visual warning that captures drivers' attention, particularly in low visibility situations, while cones can help guide traffic away from the accident and into safer lanes.

Redirecting traffic is essential not just for the safety of those involved in the accident but also for the smooth flow of vehicles. It helps prevent further incidents that could occur if vehicles slow down or stop unexpectedly in a hazardous situation. This proactive approach reflects best practices in accident management and ensures that emergency responders can work without interference from passing vehicles.

Other strategies, like only asking drivers to slow down or relying solely on warning signs, lack the necessary physical measures to control traffic effectively. Waiting for traffic to clear on its own is impractical and could lead to further accidents or delays, as it does not take into account the current conditions and risks present at the scene.
