HVSA shall be worn when uniformed law enforcement direct traffic, investigate crashes, or handle lane closures; not for which routine activity?

• A. Routine Traffic Stops
• B. Directing traffic at a crash scene
• C. Investigating crashes
• D. Handling lane closures

Answer: (A)

High-visibility safety apparel is required to protect responders when they are working on or near roadways with traffic, where they are exposed to moving vehicles and hazards. Directing traffic at a crash scene, investigating crashes, and handling lane closures all place personnel in or beside active traffic lanes or in temporary work zones, so being highly visible helps drivers notice them from a distance and reduces the risk of being struck.

Routine traffic stops are typically brief and can occur in comparatively safer, more controlled settings (often with a patrol vehicle present and lights on), so the same level of high visibility gear isn’t mandated in that context. That’s why routine traffic stops are the activity not covered by the HVSA requirement in this scenario.
