ANSI/ISEA 107 sorts high-visibility apparel by type and class. Type O is for off-road work, Type R for roadway and temporary traffic control zones and Type P for public safety. Class 1 needs the least material, Class 2 more, and Class 3 the most, requiring sleeves or full-body coverage. Roadway workers usually need at least Class 2, and Class 3 is common for high-speed traffic, night work and flaggers.
The tag on a hi-vis garment shows its type and class. Wearing the right one is required on many jobsites and roads.
Types
| Type | Setting |
|---|---|
| O (off-road) | No traffic exposure, e.g. warehouses, oil fields |

Federal highway rules require high-visibility apparel meeting ANSI 107 for workers on federal-aid highways. Your employer’s traffic control plan may require more.
Colors and care
Fluorescent yellow-green, orange-red and red are the approved background colors. Fading and dirt reduce visibility; replace garments when they look dull. Follow wash instructions so reflective tape stays bright.
Complete the kit with hard hats and safety boots.

Common questions
What is the difference between Class 2 and Class 3 hi-vis?
Class 3 requires substantially more background and reflective material and covers the arms or legs, making the worker visible at greater distances.
Do I need Class 3 hi-vis?
Often for work near high-speed traffic, at night or in poor visibility. Your employer, the traffic control plan and federal and state rules decide.
What does Type R mean?
Roadway: apparel for workers exposed to traffic on public roads or in temporary traffic control zones.
Is a Class E garment real?
Class E pants or shorts are not compliant alone, but worn with a Class 2 vest or jacket they make a Class 3 ensemble.
