Clearing the incident scene of vehicles is a highly effective method for reducing the hazard level during a traffic incident. When vehicles involved in an accident or breakdown are removed from the roadway, it minimizes the potential for secondary accidents, which can occur due to obstruction or the increased risk of collision with stopped or disabled vehicles. A clear scene allows emergency responders to work more efficiently and safely, ensuring that the situation is resolved as quickly as possible. This action directly addresses the physical presence of hazards on the roadway.

In contrast, while establishing safety barriers can enhance the safety of crews and responders, they do not remove the underlying hazard of the incident itself. Turning off all vehicle lights can actually create a more dangerous situation as other drivers may not see the vehicles involved in the incident, leading to confusion and potential collisions. Restricting traffic to one lane indefinitely may manage traffic flow but does not actively reduce the hazard; instead, it can lead to congestion and increase the likelihood of accidents as drivers attempt to navigate around the incident.
