Working in barrier installation, traffic management, or road safety is among the highest-risk occupational categories in the UK. Workers operating adjacent to live traffic lanes, in car parks, on construction sites, and around moving plant are exposed to significant hazards every single shift. The right personal protective equipment (PPE) is not optional — it is a legal requirement and a fundamental component of any site's safety management system.
This guide covers everything you need to know about safety clothing and PPE for barrier and traffic management work in the UK, from high-visibility garment standards through to footwear, gloves, and head protection.
The Legal Framework
PPE in the UK is governed by several overlapping pieces of legislation:
- Personal Protective Equipment at Work Regulations 1992 (as amended 2022): Require employers to provide suitable PPE where risks cannot be adequately controlled by other means
- Health and Safety at Work etc. Act 1974: Places a general duty on employers to ensure the health, safety, and welfare of employees
- Construction (Design and Management) Regulations 2015: Mandate specific safety management arrangements for construction sites
- Traffic Management Act 2004 and New Roads and Street Works Act 1991: Establish the framework for safe working on or near roads
PPE must be appropriate to the risk, properly maintained, and workers must be trained in its use. Providing PPE and failing to train workers in its correct use does not discharge your legal duty.
High-Visibility Clothing: Classes Explained
High-visibility (hi-vis) garments in the UK are governed by EN ISO 20471:2013+A1:2016, which classifies garments into three classes based on the minimum area of fluorescent background material and retroreflective tape:
Class 1 (Lowest Visibility)
- Minimum 0.14m² fluorescent material
- Minimum 0.10m² retroreflective tape
- Suitable for environments with very slow vehicle speeds (car parks, pedestrian areas) where there is no direct exposure to moving traffic
- Typical garments: tabards, lightweight vests
- Not suitable for road or construction site use where vehicles move at normal road speeds
Class 2 (Medium Visibility)
- Minimum 0.50m² fluorescent material
- Minimum 0.13m² retroreflective tape
- Suitable for construction sites, loading bays, and environments with vehicle movement up to approximately 40mph
- Typical garments: bib vests, waistcoats, jackets
- The minimum class required for most UK construction site environments
Class 3 (Highest Visibility)
- Minimum 0.80m² fluorescent material
- Minimum 0.20m² retroreflective tape
- Required for work adjacent to live traffic on roads where vehicles travel at speeds above 40mph
- Typical garments: full jackets, coveralls, trousers with jacket combination
- Mandatory for traffic management operatives working on national roads and motorways
Colour Requirements
EN ISO 20471 recognises fluorescent yellow-green, fluorescent orange-red, and fluorescent red as approved background colours. In the UK:
- Fluorescent yellow (also called yellow-green) is the default and most visible colour in daylight conditions
- Fluorescent orange provides better visibility in certain lighting and environmental conditions and is sometimes specified for specific roles
- Retroreflective tape must be silver/grey in colour
Hi-Vis Garment Types for Traffic Management
For barrier installation and traffic management work specifically:
Hi-Vis Jackets
Fully EN ISO 20471 Class 3 compliant jackets with full sleeve coverage are the standard garment for operatives working on live roads. Key features to look for:
- Waterproof or water-resistant outer shell — essential for UK weather conditions
- Breathable membrane lining for comfort during physical work
- Multiple pockets — radio pocket, document pockets, tool loops
- Retroreflective tape on chest, back, shoulders, and sleeves
- ID badge holder window for site access passes
Hi-Vis Trousers
When Class 3 compliance is achieved by combining jacket and trousers (rather than a single Class 3 jacket), ensure the trouser retroreflective tape wraps around the lower leg to ensure 360° visibility to approaching drivers. Cargo pockets and knee pad pockets are useful for traffic management operatives.
Hi-Vis Softshells and Fleeces
For milder weather or layering under a waterproof shell jacket, hi-vis softshells and fleeces provide warmth while maintaining Class 2 or Class 3 compliance. Ensure any garment worn as the outermost layer is compliant with EN ISO 20471 at the required class.

Head Protection
Safety helmets (hard hats) for construction and road work must comply with EN 397:2012+A1:2012. For traffic management operatives, consider:
- Standard EN 397 safety helmets: Adequate for most construction site applications with no specific electrical, extreme temperature, or molten metal splash risk
- Hi-vis safety helmets: Available in fluorescent yellow and orange, contributing to overall EN ISO 20471 visibility compliance
- Bump caps: Not suitable for traffic management or construction — these are low-impact head protection for restricted-height environments only
- Helmet fit: Correctly adjusted head harness with chin strap for work in exposed or elevated positions
Replace safety helmets after any significant impact event, and replace as a matter of course every 3–5 years from date of manufacture (check the manufacture date stamped inside the shell).
Footwear
Safety footwear for traffic management and barrier work should comply with EN ISO 20345:2011. The key protection levels are:
- S1: Antistatic, fuel oil resistant, closed heel — minimum for light industrial environments
- S1P: S1 plus penetration resistance (steel or composite midsole) — minimum for construction and road work
- S3: S1P plus waterproof upper — the recommended standard for outdoor road and site work in the UK
- S5: S3 plus high-energy upper impact protection — for environments with heavy falling object risk
For traffic management operatives, S3-rated safety boots are the recommended standard. Look for boots with ankle support for extended periods of standing and walking on uneven road surfaces.
Gloves
Glove selection depends on the specific task:
- General handling gloves (EN 388): Cut, tear, abrasion, and puncture resistant — suitable for moving barriers, cones, and signage
- Impact-resistant gloves: For work in environments with significant struck-by or crush risk
- Anti-vibration gloves (EN ISO 10819): Where operatives regularly use vibrating tools (drills, impact drivers for sign installation)
- Cold-weather gloves: Insulated, waterproof gloves for winter operations — ensure dexterity is maintained for radio and sign operation
Eye and Ear Protection
- Safety glasses/goggles (EN 166): Required when drilling or cutting for barrier installation, or when adjacent to grinding or cutting operations
- Hearing protection (EN 352): Required where noise levels exceed 80 dB(A) (action level) — consult site noise assessment
PPE Inspection and Replacement
All PPE must be inspected before each use and replaced when:
- Fluorescent material has faded significantly (check against a new garment)
- Retroreflective tape is peeling, torn, or has lost reflectivity
- Garments are torn, dirty beyond effective cleaning, or repaired in a way that compromises compliance
- Safety helmets have been subjected to a significant impact
- Safety footwear shows exposed steel toecap, worn-through sole, or compromise to waterproofing
Frequently Asked Questions
What class of hi-vis do I need for working on a motorway?
Class 3 hi-vis (EN ISO 20471) is mandatory for working on or immediately adjacent to live motorway carriageways. This typically means a full Class 3 jacket, combined with Class 2 trousers for 360° visibility, or a specific Class 3 combination garment.
Can I wash my hi-vis jacket and maintain compliance?
Yes, most hi-vis garments are designed to be washed. Follow the manufacturer's care label — typically machine wash at 40°C, do not tumble dry at high heat. Be aware that fluorescent material degrades over time and with repeated washing. If the garment appears noticeably less bright than a new equivalent, it should be replaced.
Is there an expiry date on safety helmets?
Most manufacturers recommend replacing safety helmets every 3–5 years from the date of first use, or after any significant impact. The manufacture date is stamped or moulded inside the shell. UV exposure, chemical contact, and paint can degrade the helmet's structural properties over time.
Do subcontractors have to provide their own PPE?
Under the PPE at Work Regulations 1992, the duty to provide PPE applies to the employer. Where subcontractors are self-employed and effectively working for their own business, they are responsible for their own PPE. However, site rules generally require all persons on site to wear appropriate PPE regardless of employment status, and principal contractors have duties under CDM 2015 to manage this.
