Four official pages name a garment class, a standard year, or a 1,000-foot line for work near moving traffic.
Key takeaways for the high-visibility check
- Garment class: The Minnesota page defines a high visibility garment as a Performance Class 2 garment or greater, while the Canadian page notes that CSA lists three classes of garments based on body coverage provided.
- Standard year: The California page requires warning garments manufactured in accordance with ANSI/ISEA 107-2004, and the Minnesota page specifies the same ANSI/ISEA Standard 107-2004 for its Class 2 definition.
- Visibility distance: The Federal Highway Administration page states that retroreflective material shall be visible at a minimum distance of 1,000 feet.
- Coverage: The Minnesota rule applies to each employee exposed to or working adjacent to moving motor vehicle traffic as part of the employee's assigned job, excluding police and fire protection personnel covered by subpart 3.
- Material colors: The Federal Highway Administration page lists orange, yellow, white, silver, yellow-green, or a fluorescent version of these colors as acceptable for the retroreflective material.
What high-visibility gear the official pages name for work near traffic
The Federal Highway Administration page states that retroreflective material shall be visible at a minimum distance of 1,000 feet, according to Federal Highway Administration. This distance requirement applies to the material specified on that page. The Minnesota Office of the Revisor of Statutes page requires that each employee exposed to or working adjacent to moving motor vehicle traffic be provided with and required to wear a high visibility warning vest or other high visibility garment, according to Minnesota Office of the Revisor of Statutes. This rule covers employees other than police and fire protection personnel covered by subpart 3. The Minnesota page does not specify a particular garment class in this quoted sentence, only the requirement for a high visibility warning vest or other high visibility garment. The Federal Highway Administration page specifies the visibility distance but does not name a specific garment class in this quoted sentence. These two pages address different aspects of high-visibility gear: one specifies the visibility distance of the material, and the other specifies the requirement for workers to wear high-visibility garments when near moving traffic. You must check which page applies to your specific work situation to determine the required garment and visibility standards.
What the flagger pages say the garment must meet
The Federal Highway Administration page specifies that the retroreflective material shall be orange, yellow, white, silver, yellow-green, or a fluorescent version of these colors, and shall be visible at a minimum distance of 1,000 feet according to Federal Highway Administration. The same page states that the apparel background (outer) material color shall be fluorescent orange-red, fluorescent yellow-green, or a combination of the two as defined in the ANSI standard according to Federal Highway Administration. It further requires that STOP/SLOW paddles shall be at least 18 inches wide with letters at least 6 inches high according to Federal Highway Administration. For night operations, the page notes that except in emergency situations, flagger stations shall be illuminated at night according to Federal Highway Administration.
What the Minnesota page says about workers next to moving vehicles
The Minnesota Office of the Revisor of Statutes sets specific requirements for employees who work adjacent to moving motor vehicle traffic. According to the Minnesota Office of the Revisor of Statutes, each employee exposed to or working adjacent to moving motor vehicle traffic as part of their assigned job must be provided with and required to wear a high visibility warning vest or other high visibility garment. This requirement applies to all such employees, with the specific exclusion of police and fire protection personnel covered by subpart 3. The rule is not optional; it mandates both the provision of the gear and its active use by the worker.
The page defines the specific standard this garment must meet. A high visibility garment is defined as being a Performance Class 2 garment or greater as specified by ANSI/ISEA Standard 107-2004, according to the Minnesota Office of the Revisor of Statutes. This establishes Class 2 as the baseline performance level for the required clothing. The standard year cited in this definition is 2004. If you are selecting gear for your crew, the garment must meet or exceed this Performance Class 2 threshold to satisfy the rule as written on this page.
There is an additional condition regarding manufacturer ratings. In these cases, the garment must be rated by the manufacturer as greater than or exceeding Performance Class 1 requirements, according to the Minnesota Office of the Revisor of Statutes. This sentence highlights that the garment’s rating must be verified by the manufacturer. You should check the manufacturer’s rating on the garment’s tag or documentation to confirm it meets this specific wording.
A filled reference table of the four publishers' high-visibility rules
The following table compares the specific high-visibility rules found in the four supplied official pages. Each row lists the publisher, the garment class named in that specific page, the standard year referenced, the visibility distance stated, and the workers covered by that rule.
| Publisher | Garment Class Named | Standard Year Named | Visibility Distance Named | Who It Covers |
|---|---|---|---|---|
| Federal Highway Administration | Not named in quoted sentence | Not named in quoted sentence | 1,000 feet | retroreflective material |
| California Department of Industrial Relations | Not named in quoted sentence | 2004 | 1,000 feet | Flaggers |
| Minnesota Office of the Revisor of Statutes | Performance Class 2 or greater | 2004 | Not named in quoted sentence | Employees exposed to or working adjacent to moving motor vehicle traffic |
| Canadian Centre for Occupational Health and Safety | Three classes | 2015 (R2020) | Not named in quoted sentence | Not named in quoted sentence |
The Federal Highway Administration page states that retroreflective material shall be visible at a minimum distance of 1,000 feet according to Federal Highway Administration. The quoted sentence does not name a specific garment class or a standard year for the material itself.
The California Department of Industrial Relations page requires flaggers to wear warning garments manufactured in accordance with the ANSI/ISEA 107-2004 standard according to California Department of Industrial Relations. The quoted sentence names the 2004 standard year but does not specify a garment class or a visibility distance.
A separate sentence on the same page states that the retroreflective material shall be visible at a minimum distance of 1,000 feet, according to California Department of Industrial Relations.
Where a flagger rule and a general traffic-garment rule are not the same duty
The California Department of Industrial Relations page for flaggers specifies distinct duties that differ from general worker exposure rules. Under the California Code of Regulations, Title 8, Section 1599, flaggers' stations shall be illuminated during the hours of darkness such that the flagger will be clearly visible to approaching traffic, and flaggers shall be outfitted with reflectorized garments manufactured in accordance with the requirements of the American National Standards Institute (ANSI)/International Safety Equipment Association (ISEA) 107-2004, High Visibility Safety Apparel and Headwear, according to California Department of Industrial Relations. This sentence names a specific standard year and ties the garment requirement directly to the flagger role during darkness. The same page states that the employer shall select the proper type (class) of high visibility safety apparel for a given occupational activity by consulting the Manual, apparel manufacturer, ANSI/ISEA 107-2004, Appendix B or the American Traffic Safety Services Association (ATSSA), according to California Department of Industrial Relations. This selection duty applies to the employer for a given occupational activity, not just to the flagger. Additionally, flaggers shall be trained in the proper fundamentals of flagging moving traffic before being assigned as flaggers, according to California Department of Industrial Relations. This training requirement is specific to those assigned as flaggers.
When your crew works near traffic, check whether the specific task involves flagging moving traffic. Use a page only when that page governs the work location and task. Write the garment class named on the page that applies and confirm that garment is on site.
Illustrative example of a practice sheet
Suppose a crew of 4 works beside moving traffic on 1 shift. Suppose the page that governs that location and task names class 2 or greater. You fill 4 rows and mark each garment on site. You also copy the 1,000 feet line when that page states one. These are round practice figures only, not a real crew record.
A blank sheet for today's high-visibility check
Use this blank sheet to record the specific check for your crew working next to moving traffic. Fill in the date, the specific person or role next to traffic, the garment class named on the page you used for that decision, and whether that garment is physically on site. Copy that line onto the Construction Daily Log Checklist for Supervisors. If the crew has another task sheet the same day, such as concrete grinding controls or a hot-work handoff, keep that sheet separate from this garment line.
| Date | Who is next to traffic | Garment class named on the page used | Whether that garment is on site |
|---|---|---|---|
| Example | One worker beside moving traffic | Class named on the governing page | On site or not |
