Setting up reflective triangles is crucial for protecting the area during an accident as it helps alert other drivers to the presence of an incident on the roadway. By placing reflective triangles at appropriate distances behind the vehicle, it creates a visual warning that can prevent additional accidents, ensuring the safety of everyone involved.

While moving vehicle occupants away from the area is important for their safety, the immediate priority is to make others aware of the hazard. Sounding the horn continuously may not effectively communicate the danger to approaching vehicles and could create confusion. Unloading cargo is not relevant in this context, as it doesn’t contribute to the immediate protection of the accident scene or the safety of personnel at the site. Therefore, setting up reflective triangles stands out as the most effective initial action to increase safety during an accident.
