Cargo theft prevention starts where the truck stops
Most straight cargo theft doesn't happen on the highway. It happens when a loaded trailer sits still and nobody is watching it: at a truck stop, in a drop yard, or over a long weekend.

Cargo theft by the numbers
Cargo theft prevention for a carrier comes down to the moments a loaded trailer sits still: near the shipper, at fuel and rest stops, overnight, and over holidays. Plan those stops before dispatch, lock and seal the equipment, track the load, and give drivers a written plan for when something goes wrong.
Cargo theft rarely looks like a movie hijacking. The U.S. Department of Transportation describes most of it in plain terms: stolen trailers, pilfered containers, and parked trucks taken from truck stops, terminals, and distribution centers.
I spent more than six years in risk management before I founded Simplex, and I have led it for more than 25 years since. I treat theft like any other loss exposure: decide where the load will stop before it leaves, make it harder to take than the next trailer, and know what you will do in the first hour if it is gone. Thefts that rely on deception, such as fictitious pickups and double brokering, are covered in our guide to freight fraud.

Key takeaways
Straight theft targets parked freight
DOT's own description of straight theft is stolen trailers, pilfered containers, and parked trucks at truck stops, terminals, and distribution centers.
Fewer thefts, bigger losses
CargoNet counted 677 incidents in the second quarter of 2026, down 26% from a year earlier, while estimated losses more than doubled to $304.6 million.
Plan the first stop before pickup
The 30-minute break after 8 hours of driving can be on-duty time, such as fueling with the driver at the truck, so it never has to mean walking away from a loaded trailer.
Holidays move the risk to the days around them
Over five Labor Days, 71% of thefts happened on the Thursday, Friday, Tuesday, and Wednesday around the weekend.
Locks and trackers buy time, not immunity
They make your trailer harder to take and tell you sooner when it moves. Someone still has to answer the alert.
Your policy may set its own conditions
Theft wording can depend on where and how a loaded trailer was left, so match your parking rules to your cargo policy.

What is cargo theft, and when are loads most at risk?
Cargo theft is the taking of freight while it moves between shipper and receiver, and loads are most at risk when they are parked. DOT's 2025 request for information on cargo theft splits it into two kinds: opportunistic straight thefts of trailers, containers, and parked trucks, and organized schemes such as fraudulent carriers, staged diversions, and insider collusion.
This guide covers the first kind, the theft you prevent with planning, equipment, and driver habits.
Is cargo theft a federal crime?
Yes. Under 18 U.S.C. 659, stealing goods that are part of an interstate shipment from a truck, trailer, warehouse, or depot carries up to 10 years in prison. The shipment counts as interstate at every point between origin and destination, regardless of any temporary stop, and the waybill or shipping document is evidence of where it was going. Keep the bill of lading with the load and a copy at the office.
Is cargo theft getting worse?
There are fewer thefts, but each one costs more. Verisk CargoNet counted 677 incidents in the U.S. and Canada in the second quarter of 2026, down 26% from a year earlier, while estimated losses rose from $135.7 million to $304.6 million.
CargoNet says organized thefts of unattended, loaded trailers fell that quarter, especially in California and Texas. Physical theft is still the larger share of the problem, though: 378 events were classified as theft, against 158 fictitious pickups.
Thieves follow value and resale. CargoNet reports metal thefts, led by copper, rising from 54 to 80 in the quarter, and organized groups taking enterprise computer and networking equipment that can be worth millions but moves as ordinary dry freight. Food and beverages, household goods, and electronics led its five-year Labor Day count.
How do you plan stops to prevent cargo theft?
You plan stops by deciding, before the truck is loaded, where the trailer will sit and who will be with it. Most effective cargo theft prevention happens at dispatch, not in the parking lot.
Step 1: Plan the first stop before pickup
Send the driver to pickup rested and fueled, so the first leg can run well away from the shipper before anyone stops. Under 49 CFR 395.3, a driver may not drive after 8 hours of driving without a 30-minute interruption, and that break may be off duty, in the sleeper berth, or on duty not driving. A fuel stop with the driver at the truck counts, so the break never has to mean walking away from the load.
Step 2: Decide where the 10-hour break happens
The 14-hour window will force a stop, so choose it on purpose: a fenced, lit, staffed lot rather than a ramp shoulder or a dark side street. Truck parking is short; Congress made the shortage of long-term truck parking a national priority under Jason's Law. Planning the day around the clock is covered in our time management guide.
Step 3: Don't let loaded trailers sit unattended
Drop a loaded trailer only in a secured yard, and book delivery appointments so freight doesn't sit through a closure. Over five Labor Day periods, CargoNet found 71% of thefts on the Thursday, Friday, Tuesday, and Wednesday around the weekend, and it links the physical risk to loaded freight sitting at rest during closures.
Step 4: Flag the high-value loads
Agree on which commodities or values trigger extra steps: a team or nonstop plan, a tracker in the freight, an approved parking list, or a call-in schedule. Write it down so dispatch applies it the same way every time.
Which locks, seals, and cargo theft prevention technology help?
The useful tools either slow a thief down, show that someone tampered with the load, or tell you quickly that the trailer moved. No single one does all three.
| Measure | What it does | Its limit |
|---|---|---|
| High-security lock on the rear doors | Slows a burglary of the trailer | Does nothing if the whole trailer is hooked and driven away |
| Numbered seal, recorded on the bill of lading | Shows whether the doors were opened | Shows tampering; it doesn't prevent it |
| Kingpin or air-line lock on a dropped trailer | Keeps another tractor from hooking up and leaving | Only as good as who holds the key |
| GPS tracking with door and geofence alerts | Tells you the trailer moved or opened | Useless if nobody answers the alert at 2 a.m. |
| Covert tracker inside high-value freight | Helps police find the load if the trailer is abandoned | Adds cost; worth it for flagged loads |
| Engine immobilizer on the tractor | Stops the truck from being driven off | Doesn't protect a dropped trailer |
Technology only works with a response plan. Name who watches alerts at night and on weekends, what they do first, and when they call the police. Our loss-prevention routine follows the same logic: software raises the alert, and a person closes it.
What should drivers do to prevent cargo theft?
Drivers prevent cargo theft by keeping the load out of sight, out of conversation, and within reach. Give them these rules in writing:
- Don't discuss the load, route, or destination on the radio, on social media, or in public.
- Back the trailer doors against a wall, fence, or another trailer when parked, so they can't be opened.
- Lock the cab and take the keys, even for a short stop.
- Check the locks and the seal number after every stop, and add them to the pre-trip inspection.
- Watch for a vehicle that follows the truck from the shipper.
- If followed or threatened, call 911 first, then dispatch. Never confront anyone over freight.
One rule belongs to dispatch: a change to the delivery address or contact after pickup is verified by calling a known number before the driver turns. CargoNet warns that a criminal who changes a delivery address after pickup can bypass controls that focus only on choosing the carrier.
What should you do if a load is stolen?
Call the police first, then the people who own and insure the freight, and preserve every record. Speed matters, because a tracker ping or a camera recording is easiest to use in the first hours.
- Police: report the location and time, and have the tractor and trailer VINs, plates, unit numbers, seal number, and bill of lading ready.
- Tracking: give officers the last known GPS position and any door or geofence alerts.
- Shipper and broker: tell them in writing, the same day.
- Your insurer: report the theft as your policy's notice conditions require, and send the police report number when you have it.
- Records: save ELD and GPS data, the driver's written statement, and a request to the truck stop or yard for camera footage.
Before the next loss, read your cargo policy for conditions on unattended vehicles, required locks, or approved parking; our guide to motor truck cargo insurance covers where those gaps sit. If freight is recovered damaged, follow our steps for documenting damaged cargo.
