HVSA is the acronym for a category of protective clothing used to improve visibility. Choose the correct expansion.

• A. High Visibility Safety Accessories
• B. High Visibility Safety Apparel
• C. Hazardous Vehicle Safety Act
• D. Heavy Vehicle Safety Apparel

Answer: (B)

High Visibility Safety Apparel is the term that describes clothing designed to make workers easily seen by others, using bright colors and reflective material. The word apparel emphasizes wearable garments—like vests, shirts, jackets, or coveralls—rather than separate accessories or tools. This category is about what the person is wearing, not about a law or an unrelated vehicle concept. The other options don’t fit because “accessories” implies add-on items rather than full garments, the “Hazardous Vehicle Safety Act” isn’t a clothing category, and “Heavy Vehicle Safety Apparel” changes both the meaning and scope, misaligning with the standard purpose of improving daytime and nighttime visibility through proper clothing.
