Last month, WorkSafe Victoria slapped a Melbourne traffic control crew with a $14,000 penalty after a contractor wearing a faded Class D hi vis vest was clipped by a passing ute at dusk. The vest didn’t meet AS/NZS 4602.1 requirements for low-light conditions, and the team had ignored repeated warnings about non-compliant gear. It’s a stupid, avoidable mistake that shuts down sites and puts lives at risk. Most Australian businesses think slapping any fluorescent vest on their team ticks the compliance box, but that’s where the trouble starts. If you’re sourcing AS/NZS 4602.1 hi vis vest options for your crew, you can’t guess your way through the standards. One wrong class, one faded garment, or one cheap import can lead to serious injuries, hefty fines, or full site shutdowns. Let’s break down exactly what you need to know to stay compliant, keep your team safe, and avoid the penalties that cripple small operators.
What AS/NZS 4602.1 Hi Vis Vest Standards Require
AS/NZS 4602.1 is the non-negotiable Australian standard for high visibility safety garments used in occupational settings. It sets strict rules for fabric colour, reflective tape performance, garment labelling, and design. Put simply, any vest without this standard printed on its care label is illegal to use on Australian worksites.
Reflective tape must meet AS/NZS 1906.4, with a minimum width of 50mm that fully encircles the torso. Only two fluorescent colours are approved: yellow-green and orange-red. No plain orange, pink, or blue vests are permitted, no matter how bright they look. Every garment must also display the manufacturer’s details, vest class, and date of manufacture. If that label is missing or illegible, the vest is non-compliant.
For site managers, this means you can’t trust a supplier’s word alone. Always check the label first. Our full compliance guide breaks down labelling rules in detail: https://safetyvest.com.au/compliance-guide
AS/NZS 4602.1 Hi Vis Vest Classes Explained
Vests are split into four classes, each designed for specific work conditions. Using the wrong class is the most common compliance failure we see on site.

Class D is for day use only. It has no reflective tape, relying solely on fluorescent fabric to stand out in full daylight. It’s only suitable for indoor warehousing with bright lighting, or outdoor construction work that never runs past dusk.
Class N is for night use only. It uses retroreflective tape to bounce light back to its source, with no requirement for fluorescent fabric. It’s only for work in full darkness, where there is no natural light.
Class D/N is the most versatile, designed for both day and night conditions. It combines fluorescent fabric with reflective tape, making it the go-to choice for crews that work across daylight and low-light hours.
Class R is mandatory for roadwork and traffic control. It meets additional AS 1742.3 requirements for traffic management, with specific tape placement to ensure visibility to passing drivers. Never use non-Class R vests on active roads with vehicle traffic.
Where Sites Go Wrong With AS/NZS 4602.1 Compliance
That’s where most sites get it wrong — they pick a vest based on price, not class. Here are the four mistakes we see weekly on Australian worksites:
Wrong vest class: Using Class D vests for night shifts, or Class N vests for daytime outdoor work. Class N vests are nearly invisible in full sun, while Class D vests are useless in low light.
Faded hi-vis: Fluorescent fabric breaks down after 6–12 months of UV exposure. We regularly see sites using vests faded to a pale pastel yellow, which no longer meets the standard’s visibility requirements.
Cheap non-compliant imports: $5 vests from overseas often have 30mm tape, tape that doesn’t encircle the torso, or no AS/NZS 4602.1 labelling. They’re illegal, and SafeWork NSW will fine you on the spot for using them.
Incorrect branding placement: Large logos across the back of vests that cover reflective tape, or block more than 10% of fluorescent surface area. Branding must never obscure the garment’s safety features.
Quick Compliance Checklist for Site Managers
Use this checklist to audit your current hi vis stock in 10 minutes:
- [ ] Vest label clearly displays AS/NZS 4602.1, vest class, manufacturer details, and date of manufacture
- [ ] Reflective tape meets AS/NZS 1906.4, minimum 50mm width, fully encircles the torso
- [ ] Garment colour is only fluorescent yellow-green or fluorescent orange-red
- [ ] Vest class matches work conditions (Class D for day only, Class N for night only, D/N for both, Class R for roadwork)
- [ ] Fluorescent fabric shows no fading, tears, or staining that obscures visibility
- [ ] Branding/logos do not cover reflective tape or more than 10% of hi-vis surface area
- [ ] Vests are replaced every 12 months (or sooner if fading/staining occurs)
Industry Examples: AS/NZS 4602.1 in Action
Real worksites get this right every day by matching vests to their specific operations:
Construction: A Sydney residential build uses Class D/N vests for all crew, as they often work from dawn to dusk. They replace vests every 9 months due to heavy UV exposure on open sites.
Traffic control: A Melbourne traffic crew uses Class R vests that meet AS 1742.3, with specific tape patterns for roadwork. Vests are checked daily for fading before shifts.
Warehousing: A Brisbane logistics centre uses Class D vests for all indoor crew, as bright LED lighting eliminates low-light risks. They use yellow-green vests to contrast with orange warning signage in the facility.
Mining: A Pilbara iron ore site runs 24/7 operations, so all crew wear Class D/N vests. Orange-red is mandatory to distinguish workers from yellow site equipment.
Events: A Gold Coast music festival uses Class D vests for day setup crews, and Class N vests for night shift security. Branding is only placed on the chest to avoid obscuring back tape.

FAQs: AS/NZS 4602.1 Hi Vis Vest Questions
Can I use a Class D vest for night work if my crew carry torches?
No. Class D vests have no reflective tape, so they are invisible to drivers at night. You need Class N or D/N for any low-light work.
How often should I replace hi vis vests?
Every 12 months, or sooner if the fluorescent fabric fades. UV exposure breaks down the fluorescent dye fast, even on high-quality garments.
Are plain orange hi vis vests compliant?
Only if they are fluorescent orange-red. Plain orange does not meet AS/NZS 4602.1 colour requirements, and will fail a compliance audit.
Can I print my logo on the back of a hi vis vest?
Yes, but it must not cover reflective tape or more than 10% of the fluorescent surface area. Our custom safety vests team can design branded gear that stays fully compliant: https://safetyvest.com.au/custom-safety-vests
