Chapter 8 Guidelines

Chapter 8 of the Traffic Signs manual gives Department for Transport (DOT) guidance to companies operating on public highways. This includes the use of chevron safety markings on all vehicles that intentionally stop for work or inspection purposes (section O5).

While Chapter 8 Guidelines (Section O5) are all about protecting workers and vehicles on high speed roads, the DOT recommends the same specifications when operating on all types of highway, irrespective of speed limit.

  • Chapter 8 Guidelines

    • Chevron safety markings are required (or a solid block of fluorescent orange-red retroreflective material)
    • Chevron safety markings have to be alternate strips of fluorescent orange-red retroreflective material and fluorescent yellow non-retroreflective material:

      - Each at least 150 mm wide
      - Inclined at 45-60° to horizontal and pointing upwards
    • 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
