What this is
What is a trailer restraint and chock record?
What is a trailer restraint and chock record?
A record completed each time a trailer is worked at a dock, confirming that the vehicle is reversed and squared, the engine off, the restraint engaged and confirmed, and the driver's keys or paperwork held before anyone enters the trailer. It closes with the reverse sequence: forklift withdrawn, restraint released, keys returned, and any early departure attempt recorded.
Why does key or document control matter as much as the restraint itself?
Because the restraint only holds if nobody drives away while it is engaged, and the practical way to guarantee that is to physically hold the one thing the driver needs to leave. A restraint confirmed working with the driver still holding his keys is a control that has not been switched on, whatever the restraint field says.
Who signs it, and why two signatures?
The loader and the driver both sign at release. The loader is attesting that the site's control was applied correctly; the driver is attesting that he did not move the vehicle before it was released. A single signature only covers one side of the event that the record exists to prevent.
Scope
When is a trailer restraint and chock record required?
This record covers one trailer, at one dock, for the duration it is being worked. It is not the dock's own equipment check, and it is not where racking, yard or forklift condition belongs.
Use this template when
- A trailer is about to be loaded or unloaded and needs restraining before anyone enters it
- A trailer already at the dock is changing operation, from unloading to loading, and needs re-confirming before entry resumes
- The dock is being handed over between shifts with a trailer still attached
- A linked record needs this one to exist: links loading dock check, driver records
Do not use it for
- Loading Dock Safety Check, which confirms the dock's fixed equipment, leveller, barrier, lighting, is in working order generally, not that this specific trailer is restrained right now.
- Racking Damage Report, which reports damage found on racking, not vehicle or entry control.
- Powered Truck Daily Check, which covers the forklift's own condition, not the trailer it is about to enter.
- Pedestrian and Vehicle Segregation Assessment, which designs separation across the wider yard rather than controlling one vehicle at one dock.
- Anything outside KnowSafe, which belongs in the workspace that owns that process
Compliance mapping
Which ISO 45001 cl.8.1 requirements does this satisfy?
No standard names trailer restraint specifically. It sits under the general operational control duty to eliminate or reduce a recognised hazard, here a vehicle moving while someone is inside or on it, using the hierarchy of controls before falling back to procedure.
| Clause | Requirement | Where it lands |
|---|---|---|
| ISO 45001 cl.8.1.1 | Establish criteria for processes and implement control of those processes consistently, applied the same way at every load and unload | Header |
| ISO 45001 cl.8.1.2 | Eliminate hazards and reduce risk following the hierarchy of controls, applied to restraint and key control before entry | Before entry |
| OSHA Sec.5(a)(1) | General Duty Clause obligation to address a recognised hazard likely to cause serious harm | Before entry |
| ISO 45001 cl.6.1.2.1 | Hazard identification proactive and ongoing, covering physical condition of the workplace, here the trailer floor and support | Before entry |
| ISO 45001 cl.8.1.2 | Reduction of risk maintained through to closure, restraint held until the forklift is confirmed clear | Release |
| ISO 45001 cl.10.2 | Nonconformity identified and reacted to, proportionate corrective action taken | Release |
| ISO 45001 cl.7.5.3 | Documented information controlled and available to those who need it, evidenced by both parties' signatures | Release |
What it does not cover
- Loading Dock Safety Check, which confirms the dock's fixed equipment is in working order generally, not that a specific trailer is restrained at this moment.
- Racking Inspection, which checks pallet racking for damage, overload and missing components, a different hazard entirely.
- Racking Damage Report, which reports racking damage found at any time, not vehicle or entry control.
- Powered Truck Daily Check, which covers the forklift's own pre-use condition, not the trailer it is about to enter.
- Pedestrian and Vehicle Segregation Assessment, which designs separation across the yard rather than controlling one vehicle at one dock.
Global
Trailer Restraint and Chock Record requirements by country
No jurisdiction names trailer restraint as its own instrument. It is read into the general duty to control workplace transport risk, and enforcement follows from what a recognised hazard requires rather than from a dock-specific standard.
OSH Act General Duty Clause; OSHA general industry standards on materials handling and vehicle operations
No federal standard names trailer restraint devices, but a trailer separating from a dock while occupied is treated as a recognised, foreseeable hazard.
A record showing the restraint and key sequence was applied consistently is the evidence a citation defence relies on; a gap in the sequence reads as the hazard being known and unmanaged.
Workplace (Health, Safety and Welfare) Regulations 1992; HSE guidance on workplace transport
Duty to organise loading operations so vehicles and people are kept apart, with restraint and chocking named in HSE dock safety guidance as the expected control.
HSE inspectors treat a trailer worked without restraint, or restrained with the driver still free to leave, as a direct failure rather than a paperwork gap.
ISO 45001
Operational control clause requires the hierarchy of controls applied to a recognised hazard such as vehicle movement at a fixed workface, maintained consistently across every occurrence.
Certification audits sample individual records looking for the restraint and key fields moving together, not just for the template being in use.
How to complete it
How to complete a trailer restraint and chock record, step by step
The record prompts for a sequence of yes or no answers. The judgement calls sit in how those answers are read back, not in how they are entered.
Restraint Engaged confirms the mechanism is on. Keys Or Documents Held confirms the driver cannot act against it. Neither field alone tells you the trailer is actually secured; both together do. A record with one yes and one no has not completed the control, whatever the individual answers suggest.
Forklift Withdrawn, Restraint Released and Keys Or Documents Returned exist as three fields, but the sequence matters more than any one of them: releasing the restraint before confirming the forklift is clear reopens the exact hazard the entry sequence closed. A completed record with all three marked yes still needs the order checked, not assumed.
Trailer Floor Inspected and Trailer Legs Or Support Fitted describe a different hazard, a floor or support failing under a loaded forklift, and it is not solved by restraint or key control at all. A no on either should stop entry regardless of how the restraint fields read, and reading them as secondary detail is the gap that lets a rotten floor through.
Every other field describes what should have happened. This one records what a driver actually tried. A programme where this field is always no across every record for months is either genuinely working or nobody is asking the driver honestly, and the Case ID link exists precisely so a yes here does not disappear into the form.
What auditors find
Most common trailer restraint and chock record findings
Because the record is short and binary, findings rarely come from missing fields. They come from the sequence being right on paper and wrong in the order it actually happened.
| Finding | Clause | What fixes it |
|---|---|---|
| Restraint Engaged marked yes while Keys Or Documents Held is marked no. | ISO 45001 cl.8.1.2 | Treat the pair as a single control; a record with this combination should be queried, not filed. |
| Restraint Released recorded before Forklift Withdrawn on the same record. | ISO 45001 cl.8.1.2 | Enforce the release order at the point of entry, not by reviewing timestamps after the fact. |
| Trailer Floor Inspected marked no, with entry proceeding regardless. | ISO 45001 cl.6.1.2.1 | Stop entry on a failed floor or leg check; restraint status does not offset a structural finding. |
| Any Early Departure Attempt consistently no across every record for a haulier, with no corroborating driver interview. | ISO 45001 cl.10.2 | Spot-check the field against driver accounts periodically; a field that never moves is not evidence it never happens. |
| Second Signature missing or applied by someone other than the driver on record. | ISO 45001 cl.7.5.3 | Require both named parties to sign in person at release; a proxy signature defeats the record's purpose. |
| Restraint Indicator Confirmed answered not checked, with restraint still read as engaged. | ISO 45001 cl.8.1.2 | Treat an unconfirmed indicator as unverified restraint, not as a working one with a missing detail. |
Case in point
Case in point: the record that was complete and thirty seconds too fast
A cold-store site restrained a trailer, held the driver's keys, and had a picker inside it loading pallets within the correct sequence. Forty minutes later the load was finished, and the loader marked the record complete: forklift withdrawn, restraint released, keys returned, no early departure attempt. Every field read yes in the right places, no in the right places, and the record closed clean.
The keys had been handed back roughly thirty seconds before the forklift driver confirmed clear over the radio, because the loader was already walking toward the cab when the call came through and did not want to make a second trip. The trailer did not move. But the record described a sequence that, on a busier day with a driver less inclined to wait, had already stopped protecting anyone, and nothing in the completed fields would have shown that unless someone asked what order the two things actually happened in.

From a document you fill in to a programme that runs itself
The record itself is short. What decides whether it protects anyone is whether the release order is actually enforced, whether an early departure attempt gets followed up, and whether a haulier whose drivers keep testing the control gets flagged before it becomes routine.
Holds the restraint record against the register of docks and hauliers, and flags any record where restraint and key control fields do not move together.
Connects trailer floor and landing gear findings to the haulier's own vehicle condition history, rather than treating them as one-off dock observations.
Feeds trailer arrival and change-over data from the yard log, so a restraint record is expected the moment a trailer is at the dock, not filled in after the fact.

Watches for early departure attempts and repeated not-checked restraint indicators across hauliers, and raises the pattern before an incident does.

Trailer Restraint and Chock Record definitions and key terms
- Vehicle restraint
- A mechanical or hydraulic device that locks onto the trailer's rear underride bar or wheel, preventing it separating from the dock while a driver could still move it.
- Wheel chock
- A wedge placed against a wheel to stop a vehicle or an unattached trailer rolling, used with or instead of a restraint depending on the dock's fitted equipment.
- Landing gear
- The trailer's own support legs, extended once the tractor unit is uncoupled, and load-bearing before anyone works inside an unattached trailer.
- Key or document control
- Physically holding the driver's ignition key, or the paperwork he needs to leave, for the duration the trailer is being worked, so restraint cannot be defeated by simply driving off.
- Early departure attempt
- Any instance of a driver attempting to move the vehicle before it has been released, whether stopped by the restraint, by key control, or by intervention.
FAQ
Frequently asked questions about trailer restraint and chock record
Does the restraint on its own stop a trailer pulling away?+
Only if nothing has defeated it, and the most common way it gets defeated is the driver still holding his keys and simply driving off, restraint or not, on a dock without a hard interlock. Key or document control is what closes that gap, which is why the two fields are scored as a pair rather than independently.
What is the correct release order?+
Forklift withdrawn and confirmed clear, then restraint released, then keys or documents returned. Reversing any part of that order, especially returning the keys before the forklift is confirmed out, reopens the hazard the entry sequence was built to close.
Why does the record ask about the trailer floor and landing legs separately from restraint?+
Because a rotten or overloaded floor, or an unsupported trailer front, is a structural failure that restraint does nothing to prevent. A forklift can go through a bad floor with the trailer perfectly restrained. Both checks gate entry independently.
What should happen when Any Early Departure Attempt is marked yes?+
It should raise a case, using the Case ID link, rather than sit as a single field on an otherwise closed record. A yes here means the control was tested and either held or nearly failed, and that is worth more scrutiny than most other fields on the form combined.
Do both the loader and the driver need to sign, or is one enough?+
Both. The loader attests the site applied the control correctly; the driver attests he did not move the vehicle before release. A single signature only covers one side of the event, and a driver's account is exactly the version a restraint control exists to make unnecessary to rely on.
Is this the same thing as the dock's equipment check?+
No. The dock check confirms the dock's fixed equipment works in general. This record confirms one specific trailer was restrained and controlled for the load it is doing right now. A dock can pass its equipment check every shift while individual trailers on it are worked without this record ever being completed properly.
