Banksmen and Site Vehicle Safety — Keeping Vehicles and People Apart (UK Guide)

Why It Matters

Vehicles on site are heavy, often have poor visibility around them, and frequently operate in spaces never designed for them. A reversing tipper, a slewing excavator or a fast-moving dumper can kill instantly, and the people most at risk are often not the driver but the workers on foot nearby — labourers, other trades, visitors and even the public near the site boundary.

The pattern in fatal and serious incidents is depressingly consistent: a pedestrian is in a place the driver cannot see, the vehicle moves — usually backwards — and there is no time to react. Most of these incidents were entirely preventable with better site layout, a competent banksman, or a simple rule that nobody walks behind a reversing vehicle. Treating workplace transport as a top-tier risk, not an afterthought, is what separates a safe site from a dangerous one.

The Law — What You Have to Do

Several pieces of UK legislation place duties on you to manage vehicle and pedestrian movements safely. You don't need to be a lawyer to comply, but you do need to know the framework:

• Health and Safety at Work etc. Act 1974 (HSWA): the overarching duty to ensure, so far as is reasonably practicable, the health and safety of employees and anyone else who could be affected by your work — including people on foot near moving vehicles.
• Workplace (Health, Safety and Welfare) Regulations 1992: require workplaces to be organised so that pedestrians and vehicles can circulate safely, including suitable traffic routes, and that vehicles and pedestrians are kept apart wherever practicable.
• Management of Health and Safety at Work Regulations 1999: require you to carry out a suitable and sufficient risk assessment of the transport risks and put control measures in place.
• Provision and Use of Work Equipment Regulations 1998 (PUWER): apply to the vehicles and plant themselves — they must be suitable, maintained, and fitted with appropriate safety features such as mirrors, reversing aids and lights.
• Construction (Design and Management) Regulations 2015 (CDM): where they apply, the principal contractor must plan and manage traffic routes and the separation of vehicles and pedestrians across the site.

Taken together, the message is simple: you must plan how vehicles and people move, assess the risk, and control it. "We've always done it this way" is not a defence after an incident.

The Core Principle — Separate People and Vehicles

The single most effective control is physical separation: keep pedestrians and vehicles apart wherever it is reasonably practicable to do so. A person who never enters a vehicle's path cannot be struck by it. Everything else — banksmen, alarms, hi-vis — is a backup for the situations where separation isn't fully achievable.

• One-way systems: route traffic so vehicles flow in a single direction and rarely need to reverse or pass each other.
• Designated routes: mark clear vehicle routes and separate walkways so people on foot have their own protected path.
• Barriers and edge protection: physically separate pedestrian areas from vehicle routes with barriers, fencing or kerbs rather than relying on paint alone.
• Crossing points: provide defined, well-signed crossing points where pedestrians must cross a vehicle route, sited where drivers can see them.
• Exclusion zones: keep people out of the slewing radius of excavators and the working area of plant — a digger's counterweight sweeps a wide arc that catches the unwary.

Plan separation into the site from the start. Retrofitting it after a near-miss is harder and means someone has already been put at risk.

What a Banksman (Signaller) Is and Does

A banksman — also called a signaller or traffic marshal — is a trained, competent person who directs vehicle movements safely. Their job is to be the driver's eyes for the parts of the manoeuvre the driver cannot see, and to keep everyone else out of the danger zone while it happens.

A competent banksman:

• Uses a recognised, agreed set of hand signals that both they and the driver understand before any movement begins.
• Stands in a safe position — never in the path of the vehicle — where they can always see the driver and, crucially, be seen by the driver in the mirrors.
• Keeps other workers and the public out of the manoeuvring area for the whole movement.
• Maintains eye contact and continuous communication, and signals the driver to stop the instant anything goes wrong or contact is lost.

A banksman is typically needed when a vehicle is reversing, when there are significant blind spots (large vehicles, plant with poor rear visibility), or when the area is tight, congested or shared with people on foot. The rule of thumb: if a driver cannot see the whole path of the manoeuvre and be certain it is clear, a banksman (or a reliable alternative such as a properly positioned camera and exclusion zone) is required.

Avoid Reversing Wherever You Can

Reversing is the highest-risk manoeuvre on any site. The driver's visibility behind the vehicle is worst exactly when the vehicle is heading towards an area they cannot fully see. The safest control is to design out the need to reverse altogether.

• Drive-through and turning areas: lay out loading and delivery points so vehicles can drive in, unload and drive straight out without reversing.
• One-way layouts: circulate traffic in a loop so vehicles always move forwards.
• Turning circles: provide enough space for vehicles to turn around forwards rather than reversing into or out of a working area.

Where reversing genuinely cannot be avoided, it must be controlled — with a banksman, an exclusion zone behind the vehicle, and reversing aids — never left to chance.

Visibility and PPE

Even with good separation and a banksman, you need to maximise the chance that people are seen and that drivers are warned. These are layers of protection, not replacements for separation:

• Hi-vis clothing: everyone on foot near vehicle routes should wear high-visibility clothing appropriate to the conditions — the banksman especially must stand out.
• Reversing aids: cameras, proximity sensors and additional mirrors help drivers see behind and around the vehicle.
• Audible alarms: reversing alarms and, where appropriate, other warning sounds alert people that a vehicle is moving — but never assume an alarm alone keeps people clear.
• Adequate lighting: ensure traffic routes, loading areas and working zones are well lit, particularly in winter, early starts and dusk finishes.

Key Rules That Keep People Alive

A handful of simple, non-negotiable rules prevent the majority of vehicle-strike incidents. Brief everyone on these and enforce them:

• Never stand directly behind a reversing vehicle. The blind spot directly behind a large vehicle can hide a person completely.
• Agree the signals before starting. The driver and banksman must confirm the hand signals and who is in charge of the movement before the vehicle moves.
• Stop the moment you lose sight of the banksman. If the driver can no longer see the banksman in the mirror, they must stop immediately and not move until contact is re-established.
• Stay in the cab where practical. Drivers should remain in the cab during loading and manoeuvring rather than standing in the danger area.
• Watch for blind spots on large vehicles. Tippers, telehandlers and articulated vehicles have large areas the driver cannot see — assume you are not visible unless you have confirmed eye contact.

Training and Competence

A banksman is not just whoever happens to be free. The role requires training and demonstrated competence: knowing the standard hand signals, understanding where to stand to stay safe and be seen, recognising blind spots, and having the authority to stop a manoeuvre. Drivers of plant and site vehicles must hold the relevant qualifications and be authorised for the equipment they operate. Keep a record of who is trained and competent for each role, and don't let an untrained person bank vehicles in a pinch — that is exactly how incidents happen.

Site Rules and Inductions

Everyone who comes onto site — your own crew, subcontractors, delivery drivers and visitors — should be inducted on the traffic arrangements before they start. Cover the one-way system and routes, where pedestrians can and cannot go, crossing points, exclusion zones around plant, where deliveries unload, and who the banksman is. Delivery drivers in particular often arrive unfamiliar with the site, so meet them, brief them and bank them in rather than waving them through. Clear site rules, consistently enforced, are what turn good intentions into a genuinely safe site.
