What a vehicle restraint is, and why it has its own page
A vehicle restraint — also called a trailer restraint, truck restraint or dock lock — is the device at the base of the dock that physically holds a trailer in place while people and lift trucks are working inside it. Rear-impact-guard restraints engage the guard under the trailer; wheel-based types act on the wheels. A system may include inside/outside communication lights and interlocks with the leveler or dock door.
A restraint has its own mechanism, controls and service scope. A trailer that won’t release can stop a bay and leave a driver waiting, so describe that situation first.
MHI’s public standard descriptions identify ANSI MH30.3-2022 for vehicle restraining devices, separately from dock leveling and portable devices. That identifies equipment scope, not a repair or override procedure.
What's it doing?
Tell us what happened and what the lights are showing. The middle column is what a qualified provider looks at.
| What you're seeing | What a qualified provider may inspect | Why it matters | How to report it |
|---|---|---|---|
| Won't engage — trailer is in, restraint won't grab | The restraint mechanism, its controls, and whether the trailer's impact guard is in range | The bay can't be used safely, or gets used unsafely | "Bay 7, restraint won't hook the trailer" |
| Won't release — trailer is held and can't leave | The mechanism, controls, power, and any interlock holding it | There is a driver stuck at your dock right now. Say this first | "Restraint has the trailer and won't let go, driver is waiting" |
| Engages then drops off mid-load | Mechanism, wear, hydraulics or drive, and the fit to that trailer | This is the dangerous failure mode. The trailer is no longer held | "It grabbed, then let go while the lift was inside" |
| Lights show the wrong thing | Light heads, controls, wiring, and the restraint's position feedback | Incorrect signals can put drivers and dock workers at risk | "Shows green inside with nothing engaged" |
| Lights or panel message do not match the known operating state | Model-specific signal logic, control unit, wiring and position feedback | Different colors inside and outside may be normal; the actual state and instructions must agree | "Panel shows a fault and the signal has not changed" |
| Restraint won't move at all | Power, controls, motor or hydraulics, and the mechanism | Could be power, could be mechanical | "No response from the control box" |
| Interlocked door or leveler won't operate | The interlock chain and each device in it | The interlock is doing its job, or a fault in it is blocking a working bay | "Leveler won't run because the restraint won't clear" |
| Visible impact damage to the unit | The unit, its mounting, and the dock face behind it | Impact can also damage the mounting or dock face | "Trailer came in crooked and clipped it" |
| Fault code or alarm on the panel | That model's diagnostics | Codes are model-specific. They mean nothing out of context | "Panel is flashing, can't read what" |
This is the equipment we will absolutely not talk anybody through. No manual release procedure. No override. No "pull this to let the trailer go." Restraints are a safety interlock, they can be under load, and defeating one with a trailer at a live dock is how people end up between a trailer and a dock face.
If the restraint is holding a trailer: keep people and lift trucks out of the trailer, tell the driver not to attempt to pull out, take the bay out of use through your facility's normal process, and call. Don't have anyone go under or behind the trailer to look at the unit.
If a trailer is stuck, say that first.
Restraint types, in plain terms
You don't need to know which you have. If you do, it helps.
| Type | How you recognise it | Components a qualified provider may inspect |
|---|---|---|
| Hook-style (rear impact guard) | An arm or hook that rises from the dock face and catches the bar under the trailer bed | The hook mechanism, its drive, position sensing, and fit to non-standard trailers |
| Wheel-based barrier | A barrier or chock mechanism that engages the trailer wheels rather than the bar | Drive, track, debris and ice, and sensing |
| Manual with powered lights | A physical chock or bar you place, with the light system still tied in | Restraint hardware, sensing, light system and controls |
Some trailers — older ones, certain flatbed and specialty configurations, some intermodal chassis — don't present an impact guard the restraint can grab. If your restraint works on most trailers but not one carrier's, that's worth saying on the call, because it may be a fit problem rather than a fault.
Communication lights and interlocks
Communication lights convey model-specific dock instructions; color alone does not prove safe engagement or permission to move. In Rite-Hite’s published example, inside and outside signals are complementary—green outside/red inside is not inherently a fault. Follow the facility’s established process and the actual system’s instructions; do not infer a universal sequence from this page.
Interlocks may link the restraint, door and leveler. Report all affected equipment so the provider can assess the connected system.
When lights and reality disagree, that's a genuine hazard and it gets treated like one — not as a bulb. What a qualified provider checks: the light heads, the control unit, the wiring, and the position feedback coming back from the restraint itself.
Do not work around a light fault by telling drivers to ignore the signals. Report it and take the bay out of use until it's right.
If the fix involves new wiring or new power, note that Virginia's commercial contractor classifications — CBC and CIC — don't cover electrical work (18VAC50-22-30, checked September 17, 2026). Ask who's handling that piece.
Why restraints matter beyond the equipment
OSHA 29 CFR 1910.26 addresses using measures such as wheel chocks or sand shoes to prevent the transport vehicle on which a dockboard is placed from moving while employees are on the dockboard. Checked September 17, 2026. The applicable controls depend on the trailer, equipment and facility operation. A failed restraint does not make an improvised substitute acceptable.
That's why a restraint fault is worth reporting the same day rather than living with — and it's why "we just chock it for now" deserves a real conversation with your safety lead, not a shrug.
What to say when you call
Example wording for a first call. It's an example, not a script, and not a real job.
"The restraint at bay 7 in our Richmond DC won't release and the driver's waiting — I can give you the address."
Three steps after you call
- You describe it. Facility location, bay number, whether it won't engage or won't release, and whether a trailer is stuck.
- Your request may be shared. Calls may be shared with an independent commercial dock-and-door repair company.
- That company takes it from there. They confirm whether they can serve the address, what they can do, when, and what they charge — plus their own contract, work and warranty terms.
Useful, not required
Bay number. Whether a trailer is held. What the inside and outside lights are showing. Whether the leveler or door is interlocked and also blocked. Whether there was an impact. Whether it happens with one carrier's trailers or all of them. Any panel message you can read from a safe distance.
No completed checklist is required. The facility city or address, the bay number, and "restraint won't release" are enough. Nobody should be going under or behind a trailer to gather details.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
What we cover — and what we don't
In scope: trailer and vehicle restraints of common types, dock locks, their controls and power, position sensing, communication light systems inside and outside the bay, and interlocks with the leveler or dock door — at warehouses, distribution centers, plants, cold storage, food and beverage facilities and other commercial buildings.
Not in scope:
- Trailer towing or recovery, and remote instructions to defeat or manually release a restraint. Assessment and repair of a restraint that will not release remain in scope. Describe the held trailer first; the provider confirms the work it can undertake.
- Trailer and truck repair of any kind, including damaged impact guards → a trailer service shop.
- Structural concrete, the dock face and slab work → a concrete contractor.
- Parts-only orders → a distributor.
- Yard management software and telematics.
- Residential and marine equipment.
What affects the price
We can't quote your exact restraint repair from a web page. The price depends on the unit, the fault, parts, and access. Here's what to ask before you authorize work.
Ask whether the first visit is diagnostic. Ask whether the quote covers the mechanism only, or the controls and lights too, because mechanism, controls and signals are distinct assessment scopes. And ask what happens if the mounting turns out to be the problem.
| What drives it | Why it moves the number |
|---|---|
| Restraint type and model | Hook-style, wheel-based and manual units are different machines |
| Mechanical versus control fault | A bent hook and a failed control board are different jobs |
| Lights and wiring | Confirm whether diagnosis, replacement and electrical work are included |
| Interlocks | More devices in the chain means more to check |
| Mounting and dock face condition | Failed supports may need a separate structural repair |
| Whether the bay can be released | Hard to work on a restraint with a trailer in it |
| Parts lead time | Control boards and proprietary parts can be the long pole |
Repair or replace the restraint?
Ask for an assessment of the mechanism, mounting, controls, compatible parts and fit with the trailers using that bay. A failed component does not automatically justify a complete replacement, but repairing a unit that cannot suit the trailer mix does not solve the fit problem.
Compare the complete proposal: restraint hardware, electrical work, communication lights, any door/leveler interlocks, commissioning and records. Ask which existing components can remain and what the manufacturer permits. Your facility’s safety lead and the qualified provider need to address operation while the affected bay is unavailable—not an improvised override.
What local checks apply to restraint repair?
Separate repair of the restraint from changes to its anchorage, dock face, new power or interlocked door controls. Tell the building official exactly what will change and ask which approvals apply. Any trailer-impact-guard repair belongs to a trailer service shop, not a dock restraint repair by implication.
Check the contractor’s actual scope and active licence through Virginia DPOR. The class thresholds consider project and annual value; the classification or specialty must cover the proposed work. CBC or CIC alone does not authorize electrical work.
Ask the building official which permits the scope requires under Virginia’s §108 provisions, including new wiring or door controls. Use the actual facility jurisdiction: Richmond, Henrico, Chesterfield, Hanover, including Ashland building permits, or Petersburg. Checked September 17, 2026.

Restraint questions from Richmond docks
Our restraint won't release and a driver is stuck. What do we do right now?
Keep people and lift trucks out of the trailer, tell the driver not to try pulling out, take the bay out of use through your facility's normal process, and call. Say "trailer held, driver waiting" at the start of the call so the provider understands the situation. Don't have anyone go under or behind the trailer, and do not attempt a release based on a website’s instructions.
Is a restraint fault the same call as a dock leveler fault?
Different equipment; the provider must confirm whether it can assess both. Restraints, levelers and doors are frequently interlocked, so a restraint fault can stop the leveler and a leveler fault can look like a restraint problem. Describe everything that isn't working at that bay and let the provider sort out the chain.
The lights are wrong but the restraint seems to work. Is that urgent?
Treat it as urgent. Drivers and dock crews act on those lights, and a signal that does not match the actual system state can be hazardous. Report it and take the bay out of use until it's checked rather than telling people to ignore the signals.
Our restraint won't grab one carrier's trailers. Is it broken?
Maybe not. Not every trailer presents a rear impact guard in the position a restraint expects, and some configurations can't be engaged at all. If it works on everything else and fails on one fleet, say that on the call — it changes what gets inspected, and the provider and your facility’s safety lead must assess trailer compatibility and the appropriate documented controls.
