Chapter 8 of the Department for Transport Traffic Signs Manual provides guidelines for companies operating on public highways. This Chapter sets out a code of practice to enable the legal requirements to be met in a wide variety of circumstances.

All authorities, bodies and organisations responsible for all types of roads to which the public have access, are strongly recommended to make compliance with the requirements of Chapter 8 a condition of contract in the case of works carried out on their behalf. These roads include toll roads, tunnels and bridges, industrial parks, retail parks, leisure parks, academic, hospital, dock, railway, Ministry of Defence, heritage, park, and similar estate roads etc. (chapter 8, section d1.3)

Chapter 8 affects any operator of large or small vehicles from HGV to road maintenance trucks, small vans and cars that intentionally stop for work purposes or inspections on high speed roads.

Aiming to protect workers and vehicles that have to work on all types of highways irrespective of speed limits, Chapter 8 (part 2 section 5) specifically cites the VEHICLE CONSPICUITY REQUIREMENTS such as:

Any vehicle stopping on the highway for work purposes must be of a conspicuous colour (yellow or white).

Any vehicle used to protect the workforce or form part of the signing of the works should be of conspicuous colour and carry appropriate markings.

Any vehicle stopping on high speed high roads for works purposes or inspections shall be equipped with high visibility rear markings of a specific shape and material.

Effective signing is fundamental to an efficient and safe temporary road management scheme and helps you achieve this. provides a range of materials to mark the rear, sides and front of your vehicles, helping you to meet the requirements enumerated in the Signing Principles of Chapter 8.

High visibility markings should comprise either:

  1. Signing to diagram 7403, or
  2. The alternative light arrow sign in accordance with Section O10.3, or
  3. Chevron markings comprising alternate strips of fluorescent orange-red retroreflective materials and fluorescent yellow non-retroreflective material, of not less than 150mm width each, inclined 45-60˚ to the horizontal and pointing upwards, or
  4. A solid block of fluorescent orange-red retroreflective material.

The chevron markings and solid block of retroreflective material should cover as much of the rear-facing portion of the vehicle as possible without obscuring windows, vehicle lighting or registration plates.

Where the main body of the vehicle being used is not a recognised conspicuous colour (yellow or white), then the above markings should be supplemented by a high visibility fluorescent yellow retroreflective strip, of not less than 50mm wide, along the side of the vehicle as a minimum.

Vehicles used for works purposes shall be identified by displaying to the rear “HIGHWAY MAINTENANCE”.

“MOTORWAY MAINTENANCE” may be used instead when working on motorways only. helps you meet the regulatory requirements clearly enumerated in the Traffic Signs Manual.

While chapter 8 is not yet a legislation, we are leaving ourselves open to potential legal action should any accident happen to our fleet. Because officially, the Health and Safety at Work (NI) Order 1978 requires all clients, employers, and employees to establish and maintain a safe system of work.
