MFA Follow On Practice Test

The key idea is protecting people from harm as vehicles move. The marshaller serves as a human traffic controller, guiding drivers with clear signals and maintaining a safe zone so nothing unexpected places workers in the path of a moving vehicle. That direct focus on preventing someone from being struck by a vehicle is what prevents injuries in this scenario—the action most tightly linked to worker safety during vehicle movement. Other safety concerns matter, but they don’t address the immediate risk in the same way. Securing a load prevents cargo from shifting, and ensuring equipment is safe reduces broader hazards, while considering weather helps plan the operation. None of these tackle the specific injury risk from a moving vehicle in the same direct, situational way that preventing personnel from being struck does.
