Chapter 8 of the Traffic Signs Manual (Traffic Safety Measures and Signs for Roadworks and Temporary Situations) was issued by the Department for Transport in 2006. On high-speed roads, all vehicles stopping on the highway for work purposes or inspections must comply with Chapter 8.
"On high-speed roads, all vehicles stopping on the highway for work purposes or inspections shall be equipped with high visibility rear markings."
HIGH VISIBILITY REAR MARKINGS SHOULD COMPRISE EITHER:

(b) a solid block of fluorescent orange-red retro reflective material.
The markings described should cover as much of the rear-facing portion of the vehicle as possible without obscuring windows, vehicle lighting, or registration plates. A vehicle used for work purposes should be identified by displaying a reflective sign with the phrase "HIGHWAY MAINTENANCE".
In addition, there are other specific circumstances that require reflective strips along the sides and rear edges of vehicles.
