Which combination of high-visibility apparel class is correct for day and night?

• A. Daytime Class 3; Nighttime Class 2
• B. Daytime Class 2; Nighttime Class 3
• C. Daytime Class 1; Nighttime Class 3
• D. Daytime Class 2; Nighttime Class 2

Answer: (B)

High-visibility apparel uses different classes to ensure visibility under different lighting conditions. In daylight, Class 2 provides enough conspicuity without being overly bulky. At night, drivers rely on reflective material to see workers, so Class 3 offers the highest level of visibility with more reflective coverage. Therefore, the safest and most appropriate pairing is daytime Class 2 for daylight work and nighttime Class 3 for night work. The other options either underprotect at night or overprotect in daylight, which isn’t needed and can be less practical.
