OSHA 1926.201: What Contractors Must Know About Hi-Vis on Job Sites

OSHA's requirement for high-visibility apparel on construction and roadway work zones is one of the most enforced personal protective equipment regulations in the United States. Yet many contractors remain uncertain about exactly what's required, when, and for whom. This article clarifies the essentials.

The Core Regulation: 29 CFR 1926.201

OSHA's construction standard at 29 CFR 1926.201 requires that workers on or near roadways exposed to traffic must wear high-visibility apparel meeting ANSI/ISEA 107 (or equivalent). The standard references ANSI performance classes but leaves specific class requirements to the controlling agency (typically MUTCD for federal-aid highway projects).

MUTCD Requirements by Worker Type

Night Work Requirements

For nighttime operations, OSHA and MUTCD require higher visibility levels. Class 3 garments are typically mandated for workers in active roadway lanes after dark. The retroreflective tape requirement is critical — ensure your supplier provides test reports showing retroreflection performance meets ANSI 107 Level 2 or Level 3.

Common OSHA Violations

• Workers wearing non-compliant vests that don't meet ANSI classification requirements
• Using Class 1 vests in Class 2 or 3 environments
• Garments with degraded retroreflective tape (faded or peeling)
• No hi-vis apparel at all for workers near traffic

Best Practice for Contractors

Establish a written PPE policy that specifies the minimum class required for each work zone type on your sites. Document that all hi-vis garments are ANSI-certified (retain purchase records and, where possible, test reports). Inspect garments regularly and replace any with degraded retroreflective tape.
