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 Peterhead?
Sites around Peterhead that run night shifts often find traffic lights easier for drivers to read than staff waving or knocking on the cab door. Loading docks in Peterhead where drivers wait in their cabs for a hand signal can replace guesswork with a clear red and green light at every bay.
Distribution centres near Peterhead taking trailers from many different hauliers benefit from a signal every driver understands, regardless of language or familiarity with the site.
Here is what happens after you contact us about a site in Peterhead. We arrange a free survey, measure up and send a fixed written quote. If you go ahead, we manage the whole job, including ordering, delivery and coordination with your site team. Specialist installation engineers working under our management do the fitting, at times built around your loading schedule, with out-of-hours work by arrangement. Testing and handover documents close the job.
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.
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.

Survey checklist for your dock
- Drainage on recessed or sloping dock approaches
- Headroom above the opening and which track type will suit it
- Lighting inside trailers and at the dock face
- How drivers are prevented from pulling away too early
- Scope to convert ground-level doors into docks or add lift tables
- Dock height and the mix of trailers you load
Options to discuss
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.
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.
Planning, building control and safety law in Scotland
Energy standards for buildings in Scotland are set out in Section 6 of the Building Standards Technical Handbook. For new or replacement loading bay doors in Peterhead, we confirm the figure that applies to your project and check what applies at survey, rather than relying on rules written for elsewhere in the UK.
Questions about dock traffic lights and interlocks in Peterhead
Can you work outside our normal operating hours in Peterhead?
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.
Which building and safety rules apply to a site in Peterhead?
It depends on which UK nation the site is in. England and Wales use Building Regulations approval, Scotland uses building warrants and Northern Ireland uses building control approval from the council. Workplace safety is regulated by HSE in Great Britain and HSENI in Northern Ireland, and energy rules differ between nations. For your site in Peterhead, we check what applies at survey and design to it.
Will you deal with building control and planning for a project in Peterhead?
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.
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.
Are dock traffic lights enough on their own to stop drive-away?
Traffic lights on their own are a signal, not a physical barrier, so they depend on drivers obeying them. HSE lists traffic lights among the measures against early drive-away, and many sites combine them with key or paperwork control or with a vehicle restraint. The right combination should come from your workplace transport risk assessment.
