How to Choose a Work Wear Vest? | Match Class to Traffic Speed

Match the vest’s ANSI/ISEA 107 performance class to your job: Class 2 for most roadside and construction work, Class 3 above 50 mph.

A crew member wearing the wrong class of vest is exposed to traffic without the conspicuity the job actually demands. The right vest is not picked by color or price — it’s picked by hazard, traffic speed, visibility conditions, the garment’s standard label, fit, and required features. The guide below walks through each decision in the order a safety assessment should, so you can verify a vest spec quickly and know when a standard vest won’t do.

What Decides Which Class You Need?

ANSI/ISEA 107-2020 classifies high-visibility garments by Type and Performance Class: Type reflects the expected work setting, while Class reflects the amount of visible material and design attributes. Vehicle speed is the fastest separator.

• Class 1: low-risk settings — full attention to traffic, ample separation from vehicles, simple background, speeds not exceeding 25 mph.
• Class 2: complex backgrounds, inclement weather, tasks that divert attention, or traffic speeds above 25 mph but below 50 mph.
• Class 3: speeds above 50 mph, high task loads, or jobs needing conspicuity through the full range of body motion.

A vest alone may fall short of Class 3 needs if required visibility can’t be achieved through the full range of motion — in that case you need a compliant garment system, not just any vest.

What Should Be on the Label?

Look for the standard designation, Type, Performance Class, manufacturer information, and care instructions. ANSI/ISEA 107-2020 is the current edition identified by ANSI’s standards listing, and the CDC’s PPE reference outlines the standard’s scope. Do not rely on words like “high visibility” or “reflective,” or on a fluorescent color alone — confirm the garment’s actual classification on its label or manufacturer spec sheet.

The Type matters too. Type O is for off-road use, Type R for roadway and temporary traffic-control work, and Type P for public-safety activities. A roadway worker generally needs a garment labeled for that context, commonly Type R. A generic off-road vest shouldn’t be swapped in without confirming it matches the hazard. Also keep the standard straight: ANSI/ISEA 107 is not the same as ANSI/ISEA 207-2006, a separate standard historically tied to public-safety vests for emergency responders and law enforcement.

How Do You Verify Visibility and Fit?

Require coverage from all sides — OSHA training material identifies 360-degree visibility as a significant ANSI 107 requirement. ANSI addresses background, retroreflective, and combined-performance materials, covering their amounts, colors, and placement. Fluorescent material improves daytime conspicuity; retroreflective material is what carries you when illuminated in darkness. A vest that is dirty, damaged, covered by outerwear, or poorly fitted may not deliver its intended visibility.

Mesh improves ventilation in hot conditions, while solid fabric gives more wind and weather resistance. Choose pockets, radio loops, closures, and ID panels only if they don’t obscure required reflective striping. Size the vest over the clothing you’ll actually wear — it should close securely without restricting movement, and an oversized vest shouldn’t snag on equipment or hide visibility materials. Don’t cover reflective bands with jackets, backpacks, tools, or harness components. Inspect for fading, tears, contamination, missing reflective material, and failed closures, and replace a garment when wear cuts visibility.

Employers, not workers alone, should set the required class through the site hazard assessment — OSHA material says a competent person should select the appropriate class for the activity area. Employees exposed to public vehicular traffic must be provided warning vests or other suitable garments made with reflectorized or high-visibility material; garments meeting ANSI 107 are cited as appropriate examples.

Finally, remember ANSI/ISEA 107 is a garment-performance standard — not a guarantee against impact, heat, chemicals, flame, arc flash, or cold. Add separately required PPE and choose garments certified for those hazards where applicable. The Oregon OSHA fact sheet on high-visibility apparel is a useful summary for job sites.
