Class 3 Safety Vests

A Class 3 safety vest is the highest visibility rating under the ANSI/ISEA 107 standard. It is designed for workers exposed to high-speed traffic (over 50 mph), hazardous weather, or complex jobsite environments. Class 3 vests offer the most reflective tape and background fabric coverage, including full sleeves or additional torso visibility. These vests are ideal for highway crews, emergency responders, and other professionals needing maximum visibility from all angles.

To clean your hi-vis safety vest, always check the care label first. Most high-visibility vests can be machine washed in cold water on a gentle cycle using mild detergent. Avoid bleach or fabric softeners, as they can damage the reflective tape. Air dry your vest to maintain ANSI compliance and preserve long-lasting visibility and durability. For more details, read our blog posts on Can I Wash My Safety Vest? and How to Clean Reflective Clothing.

OSHA requires that workers exposed to vehicular traffic, flagging operations, highway work zones, or excavation near public roads wear high-visibility or reflectorized warning garments (29 CFR 1926.201) — typically vests in fluorescent colors with retro-reflective tape. For flaggers, OSHA specifies red or orange warning apparel and reflectorized material for night work. Under the General Duty Clause, employers must ensure worker visibility in traffic zones, which effectively means using vests that meet the ANSI/ISEA 107 standard. See OSHA's full guidance here: OSHA Standard Interpretation (Mar 11, 2002).
