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.
Is this right for your site in Melton Mowbray?
Older docks in Melton Mowbray with separate door and leveller controls can be brought into a proper sequence by adding interlocks that stop equipment working out of order. If a site in Melton Mowbray has had door panels damaged by levellers raised too early, a leveller-to-door interlock is a straightforward fix to consider.
Distribution centres near Melton Mowbray taking trailers from many different hauliers benefit from a signal every driver understands, regardless of language or familiarity with the site.
How does an installation in Melton Mowbray work? First, a free, no-obligation survey to measure up and understand the operation. Next, a fixed written quote. Then a programme agreed with you, so the work fits around deliveries, with out-of-hours slots if needed. The installation itself is carried out by specialist engineers who answer to us, and it finishes with testing, a walk-through for your staff and a handover pack.
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.

How much do dock traffic lights and interlocks cost?
Dock traffic lights and interlocks typically cost £650 to £3,400 per bay, supplied and fitted, excluding VAT. A pair of manually switched LED signals sits at the lower end, while a full interlock panel linking door, leveller, restraint and shelter sits towards the top.
What moves the price:
- Level of control: standalone lights, door-linked lights or a full interlocked sequence.
- Existing control panels: modern door and leveller panels often accept interlocks directly; older panels may need replacing with a combined bay panel.
- Sensors: door position switches, trailer presence sensors and restraint signals each add parts and wiring.
- Cable runs: distances between lights, panels and the power supply.
- Number of bays and timing: repeat bays reduce the cost per bay, while out-of-hours working adds to it.
These are guide budgets. After a free site survey we send a written quote, and that quote is the fixed price. VAT is added at the standard rate.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Drainage on recessed or sloping dock approaches
- Access for deliveries, cranes or lifting equipment during installation
- Yard gradient and the slope of the approach to the dock
- Dock height and the mix of trailers you load
- Gaps around trailers where heated or chilled air escapes
- Temperature requirements for chilled, frozen or ambient goods
Options to discuss
Full bay interlock panel
A single control panel that runs the door, leveller, restraint and shelter in the correct sequence, with indicators showing which step is active or blocked.
Restraint interlock package
Door, lights and vehicle restraint tied together so the door only opens once the trailer is held and the restraint only releases when loading is finished.
Regulations and approvals in England
Workplace safety in England is regulated by HSE. For a loading bay in Melton Mowbray, that means doors meeting regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, equipment maintained under PUWER and suitable safeguards against vehicles driving away too early. We check what applies at survey and design the bay accordingly.
Questions about dock traffic lights and interlocks in Melton Mowbray
Can you work outside our normal operating hours in Melton Mowbray?
Yes, by arrangement. Evening, night and weekend working can be planned so the installation causes as little disruption as possible to your loading schedule. Out-of-hours work can affect the price, so mention it at the survey and we will include it in the written quote. The agreed times are confirmed in the programme before the job starts.
How long does installation take at a site in Melton Mowbray?
It depends on the equipment, the number of bays, the condition of the dock and whether any building or electrical work is needed. We agree a programme with you after the survey, setting out which bays are out of use and when. Larger jobs are usually phased so that part of the dock stays open, and out-of-hours working can be arranged.
Can you work alongside our main contractor on a new build in Melton Mowbray?
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.
Can interlocks be fitted to a manual loading bay door?
Yes. A door position switch fitted to a manual door can confirm when it is fully open or fully closed. That signal lets the traffic lights change automatically and stops the leveller being raised until the door is out of the way.
