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.
Why do sites in Renfrewshire and Inverclyde choose this?
Operators in Renfrewshire and Inverclyde reviewing their workplace transport risk assessment often look at restraints when key control alone has proved hard to enforce across shifts. New-build distribution sheds in Renfrewshire and Inverclyde can have restraint rails and ducting planned into the yard slab from the start, which is simpler than cutting them in later.
Multi-tenant logistics parks around Renfrewshire and Inverclyde can benefit from restraints when several tenants share yard space and trailers from different fleets arrive throughout the day.
It starts with a free site survey in Renfrewshire and Inverclyde, where we measure the openings, check the dock and talk through how the bay is used. You then receive a fixed written quote. Once you accept, we manage the job: specialist installation engineers carry out the work under our management, planned around your deliveries, and out-of-hours working can be arranged. At handover we test everything with you and leave the documentation.
What does HSE guidance say about preventing drive-away?
HSE guidance says there must be safeguards to stop drivers driving away from a loading bay too early, and it lists vehicle or trailer restraints as one of the measures. The others it names are traffic lights and the person in charge keeping the vehicle keys or paperwork until it is safe to leave.
This comes from HSE's guide to workplace transport safety (HSG136) and its loading and unloading factsheet. The guidance sets out the outcome rather than one fixed solution, so the right combination for your site should follow your own risk assessment.
Once fitted, a restraint is work equipment under the Provision and Use of Work Equipment Regulations 1998 (PUWER), so it must be suitable, maintained in a safe condition and inspected where deterioration could lead to danger. In Northern Ireland the equivalent is PUWER (Northern Ireland) 1999, and the regulator is HSENI rather than HSE.
Our guide to preventing drive-away and trailer creep compares the options side by side.
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.

Questions
Is the site survey in Renfrewshire and Inverclyde 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.
Will you deal with building control and planning for a project in Renfrewshire and Inverclyde?
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 vehicle restraints work with all trailers?
Wheel-based restraints and sensor chocks work with most trailers, because they act on the rear wheel rather than on the back of the vehicle. Vehicles with unusual wheel positions or very small wheels need checking, so we look at the vehicles you receive during the survey.
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.
