ANSI/ISEA 107 Classes and Types Explained Simply
Last updated: October 2026.
ANSI ISEA 107 classes help employers and workers choose the right level of high-visibility (hi-vis) apparel for the risk environment. The standard uses:
- Performance Classes (Class 1, 2, 3) and
- Garment Types (Type O, Type R, Type P)
This post explains ANSI ISEA 107 classes in plain English so you can match gear to job conditions.
Safety note: Always follow the garment care label and your workplace safety program.

ANSI ISEA 107 Classes: What The Classes Mean
Class 1
The minimum visibility level — for lower-risk environments where traffic stays slow (around 25 mph or less) and workers are separated from moving vehicles. Typical jobs: warehouse workers, parking attendants, sidewalk delivery. Typical garments: basic hi-vis vests. Class 1 requires the least background and reflective material of the three classes.
Class 2
A step up for moderate-to-high-risk environments: roadway construction zones, utility crews, airport ground staff, and drivers working near traffic. Typical garments: hi-vis vests with more coverage, jackets, and bib overalls. Class 2 is the most common requirement on active job sites.
Class 3
Maximum visibility for the highest-risk situations: night roadwork, high-speed highways, emergency responders in traffic, and flaggers. Class 3 needs full-body coverage — usually a Class 3 jacket, or a Class 2 vest combined with Class 2 pants/bibs (the ensemble route). The extra coverage keeps you visible through a full range of body movement.
ANSI ISEA 107 Classes: What The Types Mean
Type O (Off-Road)
For workers not exposed to public roadway traffic (but may have moving equipment).
Type R (Roadway)
For workers exposed to roadway traffic and temporary traffic control environments.
Type P (Public Safety)
For law enforcement and emergency responders working near traffic with job-specific design needs.
Class 1 vs Class 2 vs Class 3: Quick Comparison
| Class 1 | Class 2 | Class 3 | |
|---|---|---|---|
| Risk level | Low | Moderate–high | Highest |
| Typical setting | Warehouse, parking | Road construction, utilities | Night highway work, emergency response |
| Typical garments | Basic vest | Vest, jacket, bib overalls | Full-coverage jacket, or vest + pants ensemble |
| Commonly required by | Employer/site policy | Active job sites | DOT and high-risk site rules |
Why Care And Maintenance Still Matters
Even if your garment is labeled to a class/type, performance can drop if:
- reflective tape is peeling/cracking/dull
- fluorescent fabric is faded
- heavy grime/oil film blocks reflectivity
So use the right class/type, then maintain it properly.

FAQ
What class of hi-vis do I need for roadwork?
Most roadway work requires Class 2 minimum; night work and high-speed roads typically require Class 3. Your site’s safety plan makes the final call — ask your supervisor.
Can I combine two garments to reach Class 3?
Yes — a Class 2 vest worn with Class 2 pants or bibs can achieve an overall Class 3 ensemble rating, as long as the combination is rated accordingly.
Does the class still count if my vest is faded?
Not reliably — a faded, torn, or tape-damaged garment may no longer meet its rated class even if the label says Class 2. Inspect and replace it.
