A traffic accident is a horrible event. Aside from the obvious, this creates a dangerous scenario for the everyday driver. Many passers-by are focused on the accident, and not on the road, compounding the problem, and possibly leading to additional collisions. "Rubber necking" also creates a traffic flow issue, and keeps everyone from getting where they need to be. Let's try implementing a time proven system started in the UK . Responders would erect a temporary fabric wall that blocks the accident from the view of the public. With nothing to look at, the traffic will flow normally, and drivers will remain alert.
