what should be worn at all times at a MVC unless you are directly involved in fire fighting or extrication

• A. Restroreflective vest
• B. Hard hat
• C. Safety glasses
• D. Respirator

Answer: (A)

Being easily seen is the top safety priority at motor vehicle collisions. A retroreflective vest makes you highly visible to drivers and other responders in daylight, dusk, or darkness, which helps prevent being struck while you’re working near or in roadways. That visibility is essential at all times unless you’re directly involved in firefighting or extrication, because those tasks shift your role and may require different gear or positioning.

Other PPE serves specific hazards rather than universal visibility. A hard hat protects the head from overhead hazards but isn’t needed for visibility all around the scene. Safety glasses guard the eyes from debris, but they aren’t universally required for every on-scene task. A respirator is used only when there are hazardous airborne contaminants, which isn’t a routine requirement at every motor vehicle collision.

So the retroreflective vest is the best choice because it consistently enhances safety through visibility for responders who are near traffic.
