A vehicle restraint is a device at a loading bay that physically holds a trailer against the dock until it is safe to leave. In the UK most systems act on the rear wheel, either as a powered wheel-based restraint or a sensor wheel chock. Restraints guard against early drive-away and trailer creep, and are usually interlocked with the door and dock traffic lights.
Where does this fit at a dock in Gerrards Cross?
New-build distribution sheds in Gerrards Cross can have restraint rails and ducting planned into the yard slab from the start, which is simpler than cutting them in later. Operators in Gerrards Cross reviewing their workplace transport risk assessment often look at restraints when key control alone has proved hard to enforce across shifts.
A warehouse in Gerrards Cross that already uses traffic lights may want to add restraints so the door cannot open until the trailer is physically held in place.
We never ask you to commit before you have a fixed price. A free survey at your Gerrards Cross site comes first, followed by a written quote. When the order goes ahead, we plan the installation around your operation, book any out-of-hours working you need and manage the specialist installation engineers on site. The job ends with a full test, a run-through for the people who will use the equipment and a set of handover documents.
Wheel-based or hook restraint: which suits UK trailers?
Wheel-based restraints and sensor wheel chocks suit most UK trailers, because they act on the rear wheel rather than on the back of the vehicle. Hook restraints, which catch the rear impact guard (sometimes called an ICC bar), are common elsewhere but suit fewer UK fleets.
- Wheel-based restraint: a steel guide rail fixed to the yard, with an arm or chock that moves against the rear wheel, either powered or pushed into place by the operative. It works regardless of tail lifts or underrun guard design.
- Sensor wheel chock: a heavy chock placed in front of the wheel, with a sensor or parking station that tells the dock controls it is in position. Lower cost and minimal groundwork, but it relies on someone placing it each time.
- Hook restraint: mounted on the dock face and hooking the rear guard. UK and European trailers vary widely at the rear, and tail lifts often get in the way, so this type needs checking against your actual fleet.
How does a vehicle restraint work with dock lights and interlocks?
A vehicle restraint is normally linked to the dock traffic lights and the door controls, so engaging the restraint is what allows loading to start.
A typical sequence looks like this:
- The trailer reverses on to the bay with the outside light on green and the door closed.
- The restraint engages the rear wheel. The outside light turns red for the driver and the inside light turns green for dock staff.
- The door can now be opened, and the leveller can only operate once the door is fully open.
- When loading is finished, the leveller is parked and the door closed before the restraint can release.
- The restraint releases, the outside light turns green and the driver can leave.
The exact interlocks depend on your equipment and risk assessment. See dock traffic lights and interlocks for the options on signals and control logic.

Survey checklist for your dock
- Access for deliveries, cranes or lifting equipment during installation
- Wheel guide positions and yard markings for reversing vehicles
- Drainage on recessed or sloping dock approaches
- Bumper position and wear or damage on the dock face
- Control positions, isolators and any existing interlocks
- Dock height and the mix of trailers you load
Options to discuss
Sensor wheel chock
A heavy-duty chock with a sensor or parking station that tells the dock controls when it is in place. Minimal groundwork and suited to retrofit on existing bays.
Automatic wheel-based restraint
A powered arm on a yard-mounted rail that locates against the rear wheel at the push of a button and signals the dock controls once the trailer is held.
Which rules apply in England?
Sites in Gerrards Cross fall under the rules for England. Structural changes such as forming a new opening or a dock leveller pit may need Building Regulations approval, and external structures such as loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey and build any approvals into the plan.
Questions about vehicle restraints in Gerrards Cross
Can you work alongside our main contractor on a new build in Gerrards Cross?
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.
How do you price vehicle restraints for a site in Gerrards Cross?
Guide budgets for supply and fit are £4,200 to £9,800 per bay, excluding VAT. The figure moves with size, insulation, the operator, electrics, access, any pit or groundworks and out-of-hours working. Where levellers are involved, the guide assumes an existing, sound pit. After the free survey you receive a fixed written quote, and that is the price for the agreed scope.
What warranty comes with new loading bay equipment?
New equipment comes with the manufacturer's warranty, which varies by product. Our workmanship terms are set out in writing in the quote for your Gerrards Cross site, so you can see what is covered before you commit. Check the warranty terms for any servicing conditions, and we can quote for planned maintenance once the installation is complete.
Will a vehicle restraint slow down loading?
Engaging a restraint adds only a short step to each docking, and once it is part of the interlock sequence it becomes routine for dock staff. Many sites find that a clear sequence actually reduces delays, because there is less confusion about when it is safe to open the door or release the driver.
What happens if a powered restraint loses power?
Powered restraints are normally designed with a manual release so a trailer is not trapped on the bay if power is lost. Your site procedure should say who is allowed to use the release and what checks they make first. We explain the release method at handover.
