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 Dundee and Angus?
Operators in Dundee and Angus reviewing their workplace transport risk assessment often look at restraints when key control alone has proved hard to enforce across shifts. Yards around Dundee and Angus that park uncoupled trailers at the dock can see trailers creep under forklift traffic, and a wheel-based restraint helps keep the leveller lip on the bed.
Busy cross-dock and parcel operations in Dundee and Angus with frequent trailer swaps have more chances for an early drive-away, which is where a physical restraint adds real protection.
Before anything is ordered, we visit your site in Dundee and Angus 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.

You get a tested installation, a demonstration for your team and the manufacturer documentation.
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.
What is trailer creep and how does a restraint stop it?
Trailer creep is the gradual movement of a parked trailer away from the dock, caused by forklifts braking and accelerating as they drive on and off the trailer bed. Each movement pushes the trailer forward slightly, and over a full load the gap can grow.
Creep is more likely when:
- the trailer is uncoupled from its tractor unit and resting on its landing legs;
- air suspension or brakes have not been set correctly by the driver;
- forklifts are heavy, fast or carrying dense loads such as drinks or building materials;
- the yard falls slightly away from the building.
As the trailer moves, the leveller lip can lose its bearing on the trailer bed, and in the worst case the lip slips off with a forklift on it. A wheel-based restraint holds the wheel against the rail or chock, so the trailer cannot travel forward however many times a forklift drives on and off.

Questions
Can you work alongside our main contractor on a new build in Dundee and Angus?
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.
What details do you need from us to quote for vehicle restraints?
To get started, send the site address in Dundee and Angus, 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.
Is a vehicle restraint a legal requirement?
Not in every case: HSE guidance (followed by HSENI in Northern Ireland) says there should be safeguards against drivers driving away too early, and a vehicle restraint is one of the measures it lists. Traffic lights and the person in charge keeping keys or paperwork are the others. Which measures you use should follow your risk assessment. In Northern Ireland the regulator is HSENI.
Can a vehicle restraint be fitted to an existing bay?
Yes, restraints are commonly retrofitted to existing bays. The main questions are whether the yard concrete in front of the bay is sound enough to anchor a rail, how cables will reach the dock controls, and whether the existing door and leveller panels can accept interlocks. Sensor chocks are often chosen where groundwork needs to be kept to a minimum.
