Dock traffic lights are red and green signals mounted outside and inside a loading bay to tell the driver and dock staff when it is safe to move or load. Interlocks are control links that stop equipment operating out of sequence, for example preventing the door opening until the trailer is restrained, or the leveller operating until the door is fully open.
What matters for dock traffic lights and interlocks in Briton Ferry?
Whether your unit in Briton Ferry has one dock or twenty, the survey looks at each bay's existing controls before we quote a fixed price in writing. Older docks in Briton Ferry with separate door and leveller controls can be brought into a proper sequence by adding interlocks that stop equipment working out of order.
Loading docks in Briton Ferry where drivers wait in their cabs for a hand signal can replace guesswork with a clear red and green light at every bay.
We do not give a fixed price without seeing the site. A free survey in Briton Ferry lets us check the details that affect the job, and the written quote that follows is a fixed price for the agreed scope. We plan the work around your operation, arrange out-of-hours access if you need it and manage specialist installation engineers throughout. Handover includes testing, a demonstration and the paperwork you need for your records.
What does HSE guidance say about stopping drivers leaving too early?
HSE guidance (followed by HSENI in Northern Ireland) says there should be safeguards against drivers driving away from a loading bay too early, and it names traffic lights as one of the measures. Vehicle or trailer restraints, and the person in charge keeping keys or paperwork until it is safe, are the others listed in HSE's guide to workplace transport safety (HSG136) and its loading factsheet.
Traffic lights are a signal, not a physical barrier, so they work best as part of a clear procedure or alongside a restraint. Your risk assessment should decide the combination. In Northern Ireland the regulator is HSENI.
Interlocks also touch on door safety law. Under regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, or the Northern Ireland 1993 equivalent, powered doors need suitable and effective features to prevent them trapping anyone. Interlocks must never bypass those features, and door control work should respect BS EN 12453, the standard for safety in use of power-operated doors.

Which interlocks should a loading bay have?
The most useful loading bay interlocks stop the door opening until the trailer is in place or restrained, and stop the leveller operating until the door is fully open. Beyond that, the right set depends on the equipment fitted and your risk assessment.
- Door to restraint: the door cannot open until the restraint is engaged or a trailer is detected.
- Leveller to door: the leveller cannot be raised until the door is fully open, which prevents the lip hitting door panels.
- Door to leveller: the door cannot close until the leveller is back in its parked position.
- Restraint release: the restraint only releases once the door is closed and the leveller parked.
- Shelter to trailer: an inflatable shelter only inflates when a trailer is docked.
On a bay without a restraint, a trailer presence sensor can take its place in the door logic, although it confirms a trailer is there rather than holding it. Combining interlocks with vehicle restraints gives the strongest protection against drive-away.
The same published guide range applies across Wales; access, out-of-hours working and site conditions are confirmed at the free survey.
Survey checklist for your dock
- Forklift and pallet truck loads crossing the leveller platform
- Asbestos register and any other site hazard information
- Bumper position and wear or damage on the dock face
- Gaps around trailers where heated or chilled air escapes
- Access for deliveries, cranes or lifting equipment during installation
- Working hours, shift patterns and windows for out-of-hours work
Options to discuss
Standalone LED traffic lights
A red and green pair for each bay, one outside for the driver and one inside for dock staff, switched manually from a control beside the door.
Door-linked lights
Lights that change automatically with the door position, using a door switch or a signal from the door control panel, so the outside light turns red as the door opens.
Planning, building control and safety law in Wales
Sites in Briton Ferry follow the rules for Wales. Forming a new opening or dock pit may need Building Regulations approval, and loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey, so any approvals are understood before the programme is fixed.
Questions about dock traffic lights and interlocks in Briton Ferry
Will you deal with building control and planning for a project in Briton Ferry?
We check at survey whether the work is likely to need approval. Forming a new opening or dock pit may need Building Regulations approval, a building warrant or building control approval, depending on the nation, and external structures such as loading houses can need planning permission. Where approval is needed, we explain what is involved, work with your designer or agent, and build it into the programme.
Is VAT included in your guide prices for dock traffic lights and interlocks?
No. Our customers are businesses, so guide prices exclude VAT, which is added at the standard rate. The same guide range applies in West Glamorgan as everywhere else: for dock traffic lights and interlocks, it is £650 to £3,400 per bay, excluding VAT. It covers supply and fit for a typical installation. Your fixed written quote after the free survey shows the net price, the VAT and exactly what is included.
Can you work alongside our main contractor on a new build in Briton Ferry?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
Which way round do the inside and outside lights work?
The inside and outside lights always show opposite colours. While a trailer is being loaded, the outside light is red so the driver stays put and the inside light is green so staff can work. When loading is finished and the door is closed, the inside light turns red and the outside light turns green for the driver.
Do traffic lights and interlocks need maintenance?
Yes. Lights, sensors and interlocks should be checked at each planned service visit, including testing the full sequence and confirming that steps attempted out of order are blocked. As part of the dock equipment they fall under PUWER, which requires work equipment to be maintained in a safe condition.
