What a trailer restraint does
A trailer restraint, also called a vehicle restraint, truck restraint, or dock lock, is a device at the dock face that holds the trailer against the building while it's loaded. Most use a hook or bar that catches the steel bumper bar under the back of the trailer. Others work on the trailer's wheels. Red and green lights inside and outside tell the driver and the forklift operator whether the trailer is held.
| Type | How to recognize it | Worth mentioning |
|---|---|---|
| Hook-style restraint | A steel hook on the dock face that rises to catch the bar under the trailer | "Hook-style," door number |
| Barrier or bar-style restraint | A bar that moves up in front of the trailer's rear bar | "Bar-style," door number |
| Wheel-based restraint | A device on the drive approach that blocks a trailer wheel | "It's on the ground, at the wheel" |
| Communication lights | Red and green lights inside and outside the door | Which light is on, inside and out |
| Interlocks | The restraint is tied to the door or leveler so one can't run until the other is set | "The leveler won't work until the restraint engages" |
| Manual wheel chocks | Wedges placed under the wheels by hand | Missing or damaged chocks |
Vehicle restraint manufacturers include Rite-Hite, Blue Giant, and Kelley. Knowing the brand is optional.
What's the restraint doing?
A restraint that won't engage, won't release, or shows the wrong light means that door shouldn't be used until someone qualified checks it. Tell the provider exactly what the lights and the hook are doing. They decide what to inspect.
| What you see | What a qualified provider may inspect | Why it matters | How to say it |
|---|---|---|---|
| Inside light stays red with a trailer in place | Sensors, controls, the hook's position | Staff can't tell if the trailer is held | "Door 6 shows red inside and the hook looks up." |
| Outside light green while a trailer is at the door | Sensors, control wiring, light fixtures | The driver may think it's safe to leave | "The outside light's green but we're loading." |
| Hook won't rise or won't catch the bar | Hook drive, sensors, bar height | The trailer isn't held | "The hook won't come up." |
| Hook won't release after loading | Hook drive, controls | The trailer is stuck at the door | "The hook won't let go of the trailer." |
| No lights at all | Power, controls, bulbs | No signal to anyone | "The lights are dead at door 3." |
| Alarm keeps sounding | Controls, sensors, interlock | Something is out of sequence | "The alarm won't stop." |
| Restraint bent after a trailer backed in hard | Hook, housing, mounting | May not hold properly | "A trailer hit the restraint." |
| Leveler won't work because of the interlock | Interlock, restraint sensors | The system is doing its job, or the sensor has failed | "The leveler's locked out." |
Never bypass, jumper, or override a restraint or its interlock. Don't release the hook by hand. Don't tell a driver to pull away while the restraint shows it's engaged. Use your facility's own process for taking that door out of use.

What the safety rules say
Restraints exist because a trailer that creeps or pulls away during loading is dangerous. These federal rules explain why a failed restraint takes that door out of use.
| Rule | What it says, in plain words |
|---|---|
| 29 CFR 1910.178(k)(1) | When forklifts drive into highway trucks, the brakes must be set and wheel chocks placed under the rear wheels. |
| 29 CFR 1910.26(d) | Measures such as wheel chocks or sand shoes must keep the trailer from moving while people are on the dockboard. |
| OSHA interpretation, September 14, 2005 | OSHA has said a mechanical restraint such as a dock lock can be used in place of chocks when it effectively keeps the trailer from moving, is installed, maintained, and used as the manufacturer says, and is taken out of service when damaged. |
| ANSI MH30.3-2022 | The industry standard for vehicle restraining devices (ANSI listing). It's a voluntary standard, not a law by itself. |
That third point matters. A damaged restraint doesn't meet those conditions, which is one more reason to stop using the door until it's fixed. Our guide to vehicle restraints vs. wheel chocks goes deeper.
A restraint failed with a trailer at the door
Call (385) 325-7138 and say the restraint failed, with the address, door number, and whether a trailer is there. Keep people off the leveler and out of the trailer. Follow your facility's own process for that door. The independent company that takes the call tells you whether it can take the job and when.
Here's an example of what to say: "The restraint light at door 6 stays red and the hook won't release at our Ocala facility; the bay's out of use."
If the dock is down, say so first.

Cost, and repair vs. replace
We can't quote your restraint repair from a web page. The price depends on the restraint type, the fault, parts, and access. Here's what to ask before you authorize work.
| What drives the price | Why | What to ask |
|---|---|---|
| Sensor or control fault vs. mechanical damage | Controls and lights are a different job from a bent hook | "Is it the controls or the hook?" |
| Restraint type | Hook, bar, and wheel-based units use different parts | "What type is it?" |
| Interlock wiring | Tying the restraint to the door or leveler adds work | "Does the interlock need work too?" |
| Impact damage | A hard hit can bend the housing and mounting | "Is the mounting still sound?" |
| Parts availability | Older units may need hard-to-find parts | "Are parts still made for it?" |
| Trip charge and after-hours | Changes the total | "Is there a trip charge or an after-hours rate?" |
Repair or replace? Replacement comes up when the unit is badly damaged, parts aren't made anymore, or it doesn't fit the trailers you get now. Ask for both options in writing.
Ask the company how it will price the job.
Local checks
If the fix involves new electrical work, ask who's doing it and whether it needs a permit. Inside Ocala city limits, permits go through City of Ocala Building Services. In unincorporated Marion County, it's Marion County Building Safety. Check any Florida contractor license on DBPR's license search. The provider and the office confirm what applies.
Where we take calls
Distribution centers, warehouses, and plants anywhere in Marion County can call, including the commerce parks near I-75 and County Road 484. The provider confirms the address.

Trailer restraint questions
What does it mean when the dock restraint light stays red?
A red light inside usually means the system doesn't think the trailer is held, or it's warning of a fault. Don't load or unload that door until someone qualified checks it. Tell the provider what the lights show inside and outside.
Can we keep using the door if the restraint isn't working?
Follow your facility's own procedure. Federal rules require keeping the trailer from moving while people are on the dockboard, and OSHA's allowance for restraints depends on the restraint working and being taken out of service when damaged. Ask your safety lead what your procedure calls for, such as wheel chocks, while the restraint is down.
The hook won't let go of the trailer. What do we do?
Don't force it and don't let the driver pull away. Keep people clear and call. The provider decides how to release it safely.
Do you work on the trailer's rear bumper bar?
No. The bar under the trailer belongs to the trailer, and trailer repairs aren't covered. The restraint on your building is.
