Chapter 8 chevrons explained: does your vehicle need them?
Chapter 8 of the Traffic Signs Manual is the guidance for vehicles that stop or work on the highway, and it calls for rear markings of alternating red and fluorescent yellow retroreflective chevrons pointing upwards. Clients and contracts often require it, so always check your contract's exact specification before fitting.
What is Chapter 8?
Chapter 8 of the Traffic Signs Manual is the Department for Transport's guidance on traffic safety measures and signs for road works and temporary situations. It covers how works are signed and guarded, and how vehicles that stop or work on the highway should be made conspicuous to other road users.
When people talk about 'Chapter 8 chevrons', they mean the high-visibility rear markings that the guidance describes for these vehicles.
Which vehicles need rear chevrons?
Rear chevrons are used on vehicles that stop or work on the highway, where they are at greater risk of being hit from behind. Typical users include:
- Highway maintenance and road works vehicles.
- Utility vans working at the roadside, such as water, gas, electricity and telecoms.
- Vehicle recovery and breakdown trucks.
- Traffic management, surveying and inspection vehicles.
- Refuse, street cleansing and gully emptying vehicles.
- Contractors' vans working on sites that sit on or next to the highway.
What do Chapter 8 chevrons look like?
Rear markings use alternating red and fluorescent yellow retroreflective chevrons pointing upwards. The fluorescent yellow stands out in daylight, the red marks the rear, and the retroreflective material returns headlight beams so the pattern shows up clearly at night.
The chevrons cover the rear of the vehicle, typically the rear doors and any suitable panels around them, cut to fit around handles, lights, number plates and hinges so nothing important is covered.
Vehicles with tail lifts, roller shutters, barn doors or tipper bodies need the pattern planned around how the rear opens, so the chevrons show when the doors are closed and nothing stops them opening. Send photos of the rear of each vehicle type, with the make, model and body, so the kit can be cut to fit.
Why does the exact specification matter?
Chapter 8 sets out the principle, but clients, highway authorities and main contractors often add their own requirements in the contract. These can cover the grade of retroreflective material, how much of the rear must be covered, whether side markings or additional conspicuity markings are needed, and what other signs or beacons the vehicle must carry.
Always check your contract's exact specification before ordering a kit, and send it to us with the vehicle details. A kit that doesn't match the client's spec can mean the vehicle is turned away from site.
If your vehicles work for more than one client, check whether their specs differ. Fitting to the most demanding one means each vehicle can be sent to any of those contracts.
Why are fitted kits preferred over magnetic chevrons?
Magnetic chevron panels are available, but permanent fitted kits are generally preferred for vehicles that regularly work on the highway. The reasons are practical:
- Magnets only stick to flat steel panels, so they can't follow curves, rivets or aluminium and composite doors.
- They can slip or come off at speed or in strong wind, creating a hazard on the road.
- Dirt trapped behind a magnet can scratch the paint, and moisture can mark it.
- They are easy to forget, lose or fit upside down, leaving the vehicle unmarked on site.
- A fitted kit is cut to the vehicle's exact shape and stays in place.
How much does a chevron kit cost?
Guide prices for a red and fluorescent yellow retroreflective rear chevron kit, cut to the vehicle and fitted, excluding VAT and confirmed once we know the vehicle and the spec, are:
- Car-derived or small van: £325–£495.
- Medium or large van: £395–£695.
- Truck or tipper rear: £595–£895.
How do you keep chevrons effective?
Retroreflective material only works if light can reach it, so keep the rear markings clean. Road dirt quickly dulls them, especially in winter. Wash them with the rest of the vehicle using a soft cloth and mild detergent, and avoid aggressive pressure washing at the edges.
Check the kit regularly for damage, lifting edges and fading, particularly after reversing knocks. Replace damaged sections promptly, because a partly missing pattern is less conspicuous and may not meet the client's spec. For fleets, keeping the vehicle templates on file makes replacements and new vehicles straightforward to match.
