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 Gosforth?
Older docks in Gosforth with separate door and leveller controls can be brought into a proper sequence by adding interlocks that stop equipment working out of order. Food and chilled operations around Gosforth with inflatable shelters often add interlocks so the shelter only inflates once a trailer is docked and restrained.
Sites around Gosforth that run night shifts often find traffic lights easier for drivers to read than staff waving or knocking on the cab door.
Before anything is ordered, we visit your site in Gosforth for a free survey and then send a written quote with a fixed price. From that point we manage the installation, coordinating delivery, access and any other trades. Fitting is done by specialist installation engineers engaged and managed by us, at times that suit your operation, including out of hours where agreed. You get a tested installation, a demonstration for your team and the manufacturer documentation.
How do inside and outside dock traffic lights work together?
Inside and outside dock lights always show opposite colours: when the driver sees red, dock staff see green, and the other way round. Each light is aimed at a different person, so each one only ever gives one instruction.
- Outside light, facing the driver: red means stay on the bay because loading is in progress; green means the bay is clear to leave or to reverse on to.
- Inside light, facing dock staff: green means the trailer is in place and it is safe to open the door and load; red means do not open the door or enter the trailer.
Lights can be switched in three main ways:
- Manually, by a switch beside the door, relying on dock staff to change it at the right moment.
- By door position, so opening the door automatically turns the outside light red.
- By the restraint, so the light only changes when the trailer is physically held.
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.

Options to discuss
Trailer presence sensors
Sensors that detect a trailer on the bay, used to switch lights, enable the door or trigger an inflatable shelter where no restraint is fitted.
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.
Planning, building control and safety law in England
Powered doors and dock equipment installed in England may carry the UKCA or the CE mark, and doors are covered by the product standard BS EN 13241. We hand over the relevant documentation for each item fitted in Gosforth. Planning and Building Regulations questions are never assumed either way: we check what applies at survey, so you know before work is booked.
Questions about dock traffic lights and interlocks in Gosforth
Will you deal with building control and planning for a project in Gosforth?
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 the site survey in Gosforth free?
Yes. For new installations, replacements, upgrades, conversions and complete bays, the site survey and written quote are free and come with no obligation. The survey lets us measure the openings, check the dock and structure, and understand how the bay is used, so the quote reflects your site. Repair and servicing visits are different: they are chargeable, with the price agreed before anyone attends.
What details do you need from us to quote for dock traffic lights and interlocks?
To get started, send the site address in Gosforth, the number of bays or openings, approximate sizes, and photos of the dock from inside and outside. Tell us what vehicles you load, what goods you handle and any temperature requirements. Drawings help on new builds. We then arrange the free survey and confirm the details before the written quote is issued.
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.
Will interlocks slow down my loading operation?
Interlocks add a fixed sequence, but each step takes only moments and staff soon get used to it. In practice many sites find the sequence saves time overall, because there are fewer arguments about when to open the door and less damage from levellers being raised into part-open doors.
