Chapter 8 refers to Chapter 8 of the UK Traffic Signs Manual, which sets out the legal requirements for temporary traffic management (TTM) on highways. It specifies how roads must be signed, lit and protected during roadworks, including the use of barriers, cones, signs and vehicles. All Chapter 8 equipment must meet specific safety standards.
What is Chapter 8? — The Complete Guide to UK Temporary Traffic Management
If you've ever driven through roadworks in the UK, everything you saw — the cones, signs, barriers, signal boards and stop/go boards — was deployed in accordance with Chapter 8 of the Traffic Signs Manual. It is the definitive reference document for temporary traffic management on UK roads and compliance with it is a legal requirement under the Road Traffic Regulation Act 1984 and the Traffic Signs Regulations and General Directions (TSRGD) 2016.
The Full Title and Legal Basis
The full title is "Traffic Signs Manual — Chapter 8: Traffic Safety Measures and Signs for Road Works and Temporary Situations." It is published by the Department for Transport (DfT) and has been through several editions — the current version was published in 2009 (Part 1) and 2020 (updated guidance). Chapter 8 is given legal effect through the TSRGD and associated regulations. Non-compliance with Chapter 8 when working on or near a public highway exposes contractors to significant legal liability if an incident occurs.
Who Does Chapter 8 Apply To?
Chapter 8 applies to anyone working on the public highway in England, Scotland and Wales (Northern Ireland has equivalent but separate guidance). This includes:
- Highway authorities (councils, National Highways, Transport Scotland)
- Utility companies (water, gas, electricity, telecoms) carrying out streetworks under the New Roads and Street Works Act 1991
- Contractors carrying out works on the highway under Section 50 licences
- Event organisers using temporary closures under the Road Traffic Regulation Act
Anyone placing signs, cones, barriers or other traffic management on the public highway is expected to comply with Chapter 8 provisions, regardless of the scale of the operation.
Chapter 8 Approved Equipment
Chapter 8 specifies a comprehensive range of approved equipment for use in temporary traffic management:
Barriers
- Plastic water-filled barriers (also called Jersey barriers or New Jersey barriers) — for lane separation and site protection
- Rigid plastic barriers — step-barriers and traffic management barriers
- Armco (corrugated steel beam) barriers — for roadworks requiring vehicle restraint
- Pedestrian barriers — for separating pedestrians from road works
- Longitudinal traffic barriers — installed parallel to the road for carriageway separation
Traffic Cones
Chapter 8 specifies cone heights, spacing intervals and reflective qualities for different road types and speed limits. Cones must comply with BS EN 13422 for road cones.
Signs
All temporary traffic signs used in roadworks must comply with the TSRGD. Chapter 8 specifies which signs are required, where they should be placed, and the advance warning distances appropriate for different speed limits.
Lighting
Chapter 8 specifies lighting requirements for roadworks sites — including barrier lights, cone lights and vehicle-mounted lights. All lighting must comply with BS EN 12352.
Chapter 8 Training and Qualifications
Anyone installing temporary traffic management under Chapter 8 should hold the appropriate LANTRA Award for Signing, Lighting and Guarding (SLG) qualification. There are three categories:
- Category 1 — Low-risk locations: footways, cycleways, off-road, and minor roads
- Category 2 — Carriageway works on roads with speed limits up to 40mph
- Category 3 — Carriageway works on roads with speed limits exceeding 40mph
For high-speed (Category 3) locations, LANTRA also provides a higher-level qualification for Traffic Management Operatives working on National Highways motorway and trunk road schemes.
Chapter 8 Barriers — The Key Types
Water-Filled (Kentledge) Barriers
Water-filled barriers — often called "Jersey barriers" — are plastic shells that can be filled with water on-site to provide ballast and vehicle containment. They are interlocking and available in 1m and 2m lengths. When filled, a standard 1m water-filled barrier weighs approximately 300kg, providing meaningful resistance to errant vehicle impact. They are the most widely used Chapter 8 barrier type for lane separation and site protection on UK roadworks.
Rigid Plastic Barriers
Step-barriers and rigid plastic barriers are used where water filling is not practical. They are lighter and easier to handle than water-filled barriers but provide less vehicle containment.
Concrete Barriers
Precast concrete New Jersey profile barriers — typically 1.8m long sections — are used for higher containment applications, including on motorway schemes where they are specified under National Highways Interim Advice Note (IAN) requirements.
Chapter 8 and the New Roads and Street Works Act 1991 (NRSWA)
Chapter 8 works on public highways carried out by utility companies and their contractors are governed by the New Roads and Street Works Act 1991 (NRSWA). NRSWA requires that streetworks are notified to the relevant highway authority and that the works are carried out by operatives with the appropriate NRSWA qualifications (assessed by City and Guilds). Works must be safe, minimise inconvenience and meet the technical requirements of Chapter 8.
Common Chapter 8 Violations and Penalties
Non-compliance with Chapter 8 can result in: Fixed Penalty Notices from the highway authority, prohibition notices stopping works, prosecution under the Highways Act 1980 or Road Traffic Act 1988, civil liability if a road user is injured as a result of inadequate traffic management, and invalidation of insurance. Consequences for Chapter 8 breaches can be severe — especially if a serious accident occurs at an improperly managed roadworks site.
