Chapter 8 markings: what we need to know

To quote Chapter 8 markings correctly we need the vehicle (make, model, weight, body and rear layout), where it works (especially roads of 50 mph and above), and whose specification applies. Chapter 8 is guidance that's usually made binding by your client's contract, and contracts often add their own requirements.

Last reviewed 10 November 2026

The vehicle

  • Make, model and year, plus date of first use (or manufacture, for trailers)
  • Gross vehicle weight: under 3.5 t, 3.5–7.5 t, or over 7.5 t
  • Body type and base colour
  • Rear layout: doors, shutter, tail-lift, lights and number plate, with photos and measurements
  • Rear-mounted equipment, such as crash cushions or cone-laying kit

How and where it works

  • The highest speed limit it regularly works on
  • What it does: inspection, works, mobile works, traffic management or incident response
  • Which nations it operates in

Whose rules apply

Send us your client's livery or conspicuity specification and any contract clause. Some specify material classes or layouts beyond the guidance. Larger goods vehicles and trailers may also need ECE 104 / UN R150 contour markings, which are a separate legal requirement.
