Are Hi-Vis T-Shirts Safer? What the Regulations Say

High-visibility (hi-vis) T-shirts can significantly improve safety on job sites — but only if they meet the correct standards and are used in the proper environment. This article explores their effectiveness, what U.S. regulations require, and whether they’re a worthwhile investment.

Are Hi-Vis T-Shirts Safer?

Yes — when compliant with ANSI/ISEA regulations. Hi-vis T-shirts are designed to make the wearer more visible, especially in low-light or high-traffic conditions. They’re especially important for:
  • Construction workers
  • Utility and roadside crews
  • Warehouse personnel
  • Emergency responders

What Do the Regulations Say?

ANSI/ISEA 107-2020 Standard

In the U.S., high-visibility apparel is governed by the ANSI/ISEA 107-2020 standard. It classifies garments based on:
  • Performance Class (1, 2, or 3) – based on the amount of visible material
  • Type (O, R, or P) – based on work environment:
    • Type O (Off-road): Warehouses, parking lots
    • Type R (Roadway): Roadwork, construction
    • Type P (Public safety): Law enforcement, EMS
To comply, hi-vis T-shirts must have fluorescent background colors and reflective striping arranged for 360° visibility. They must also be labeled with the appropriate ANSI class and type.

Referenced Federal Regulations

  • MUTCD (Manual on Uniform Traffic Control Devices) – requires ANSI Class 2 or 3 garments for workers near public roads.
  • OSHA 1926.651(d) – mandates visibility protection for highway and road construction.

Are They Worth It?

Yes, in safety-critical environments. Compared to regular shirts, compliant hi-vis T-shirts offer increased safety, help avoid OSHA citations, and are often required by employers or contracts. Costs are reasonable (typically $10–$30), and many employers provide or reimburse them. They reduce accident risks and contribute to a culture of safety.

Limitations

Hi-vis T-shirts may not be sufficient in certain situations, such as:
  • Nighttime work – Class 3 jackets or long-sleeve gear may be required
  • High-speed traffic zones – more reflective material and limb coverage is necessary
