SEMI-TRAILER
Find the right semi-trailer GPS tracker to monitor location, stops, and movement of your trailer fleet with live tracking on our platform.
A semi-trailer GPS tracker lets you keep track of a trailer that spends part of its life detached from any truck, parked at a yard, a customer site, or a border crossing. Unlike a vehicle tracker tied to one cab, a trailer unit has to work independently, often running on its own battery or on power pulled briefly whenever it is coupled. This category is built for transport companies, logistics operators, and owners of semi-trailers who need to know where a trailer is at all times, whether it is loaded, parked, or being towed without authorization.
Semi-trailers are frequently left unattended for days, which makes them an easy target for theft, and a loaded trailer represents real cargo value, not just the cost of the chassis. Tracking also helps with everyday operations: confirming a trailer reached the right yard, checking how long it sat idle before pickup, or proving delivery times to a customer.

Why semi-trailers need their own tracking approach
A truck tracker assumes constant power from the vehicle. A semi-trailer does not. It may sit disconnected for weeks, so the tracker needs either a strong internal battery, a backup battery that keeps reporting after main power is cut, or both. Movement and towing alerts matter more here than on a powered vehicle, since an unexpected move while the trailer should be stationary is usually the first sign of theft.
How to choose a tracker for a semi-trailer
Start with power. If the trailer has no reliable 12V or 24V supply when parked, a model with its own long-life battery, such as the Teltonika FMC234, is a better fit than one depending on vehicle power. For trailers that do get powered periodically, the Teltonika TAT140 4G works well as a backup unit, since it keeps reporting location even after the main power source is disconnected, which is exactly the scenario of an unhitched trailer.
Other points to check:
- Waterproof housing, since trailer mounting points are exposed to rain, dust, and road spray
- Battery life in idle mode, important for trailers parked for long periods
- Towing and movement detection, to get an alert if the trailer moves without the expected tractor unit
- 4G connectivity for stable reporting across the route, including the Teltonika FMC234 and Teltonika FMB204
Installation and subscription
Installation on a semi-trailer is usually simple: the unit is mounted in a protected spot on the chassis or inside a storage box, with no complex wiring needed on battery-powered models. Units that use backup or vehicle power need a connection to the trailer's electrical system, which our installers handle correctly for each model.
The subscription includes a SIM card provisioned for GPS data, access to our tracking platform, and mobile apps for live position, history, and alerts. A tracker sold without a subscription still has GPS hardware inside it, but with no SIM data plan and no platform access it cannot send its position anywhere, which defeats the purpose of tracking a trailer that moves on its own schedule. Our subscription keeps the SIM active, the platform running, and alerts configured for towing, geofence exit, and idle time.
Real use cases
A logistics company with a pool of forty semi-trailers uses tracking to know instantly which trailers are available at which yard, cutting the time spent calling drivers or walking the lot. A transport operator hauling high-value goods relies on towing alerts to get notified the moment a trailer moves outside of a scheduled pickup window. A trailer rental business tracks units across multiple customers to confirm they stay within agreed routes and are returned on time.
Frequently asked questions
Does a semi-trailer tracker need the trailer to be connected to a truck?
No. Models like the Teltonization FMC234 run on their own battery, so they report location whether the trailer is attached to a tractor unit or sitting alone in a yard.
Can I get a tracker without a subscription?
The hardware can be bought on its own, but without an active SIM and platform access it cannot transmit any location data. Our subscription is what actually makes the tracker useful day to day.
How long does the battery last on a parked trailer?
It depends on the model and the reporting interval set on the platform. Battery-powered units are chosen specifically for long idle periods between trips.
Will I get an alert if someone tows my trailer without permission?
Yes, movement and towing alerts can be set up on the platform so you are notified as soon as the trailer moves outside expected conditions.
