Thousands of law enforcement agencies trust All Traffic Solutions® variable message signs and radar speed signs to tackle their challenges. We’ve expanded our traffic sign trailer offerings to help power and mobilize the technology our customers rely on. Our plug-and-play solutions save time and reduce technology installation expenses, providing enhanced convenience and performance.
Learn about the tech-ready trailer options available to you:
LPR Camera-Ready Trailers

LPR camera-ready trailers are equipped with a radar speed or variable message sign along with LPR (license plate recognition) technology. The license plate readers capture the license plates of cars driving on roads. They are used to help locate vehicles of interest, apprehend suspects, and recover stolen vehicles. LPR cameras are mostly used by law enforcement.
Now, we are offering an option to enhance your existing system by offering a high-quality radar message trailer that is compatible with your existing LPR technology. We work with your preferred camera brand to ensure that the LPR camera system of your choosing is seamlessly installed on our mobile trailers. Over the past year, our skilled team has built over 100 LPR-ready trailers to meet the needs of our customers. With that experience, our skilled team knows the intricacies of integrating our trailers with numerous LPR cameras. This allows us to deliver a fully integrated and easy-to-deploy solution upon delivery.
We can attach cameras to our trailers in a variety of ways: in a two-camera enclosure box, to the crossbar at the top of the trailer, to the middle of the trailer frame, or in a compartment on the back of the battery box.


These trailers are equipped with either a radar message sign or a variable message sign, making them traffic sign trailers too. These signs enable you to share information, reduce speeding, and collect traffic data while also capturing license plates.
We offer two power options for the ATS LPR Camera-Ready Trailer:
- 190 LPR Camera-Ready Trailer: Ideal for powering one license plate reader camera
- 380 LPR Camera-Ready Trailer: Ideal for powering multi-camera license plate reader systems
Surveillance-Ready Trailers
The ATS Surveillance-Ready Trailer is a plug-and-play solution for surveillance cameras, giving you the power to deploy and easily move surveillance cameras whenever needed. This mobile surveillance trailer features a detachable telescoping mast that reaches a height of up to 22 feet. It can be fully extended in 30 seconds with the help of an easy-to-use, hand-operated pneumatic lift. When compacted and detached from the trailer hitch, it fits easily in the trunk of a car for hassle-free portability.

These trailers are highly mobile, making them easy to deploy in areas of interest. You won’t need to rely on other agencies for help with transportation or to borrow their equipment—these trailers give you the power of on-demand surveillance, whenever and wherever you need it.
This adaptable trailer is compatible with a wide range of surveillance cameras, so you can select the camera brand of your choice. Like the LPR camera-ready trailer, it is also equipped with a radar message or variable message sign. This adds more functionality to the trailer overall, including message sharing, traffic calming, and traffic data collection alongside camera operation.

This camera trailer is perfect for surveilling an area while also providing traffic or event information. They can be deployed to help manage traffic for special events, while also recording the area to capture evidence of any crimes being committed. Their presence can also be a deterrent for crime and is perfect for increasing situational awareness.

ATS 5 FLEX Trailers

The ATS 5 FLEX Trailer is a versatile, portable, plug-and-play solution. It can be equipped with the technology you need—whether it’s cameras, sensors, or other equipment.
Designed for rapid deployment, the ATS 5 FLEX trailer allows you to position and power your tech whenever and wherever needed. With 380W solar assist, this trailer provides extended runtime for your equipment. The power can support both the technology and data collection.
If you are simply looking for a trailer with additional power, the expanded solar and battery built into our FLEX trailers provide you extended run time to deploy the trailer with the traffic sign for longer periods of time throughout the year. In the meantime, you can still use this traffic sign trailer to share important information and reduce speeding in your community.
Integrating your technology with our trailer is hassle-free. All Traffic Solutions takes care of the installation, saving you time and money. If issues arise, we’re here to provide support for the trailers and radar/message signs. We want to ensure the ATS 5 FLEX trailer meets your needs as a surveillance trailer, AI camera trailer, sensor trailer, and more.
We offer two power options for the ATS 5 FLEX:
- 190W Trailer: Ideal for up to 30W solutions to achieve continuous and uninterrupted solar/battery power autonomy*
- 380W Trailer: Ideal for up to 50W solutions to achieve continuous and uninterrupted solar/battery power autonomy*
*Time of year, location & sign usage can cause variations in run times.
ATS 5 and ATS 3 Radar Speed and Message Traffic Sign Trailers
If you don’t need cameras attached to your trailers, we offer radar speed and message trailers that are perfect for reducing speeding, sharing information, and collecting traffic data.
ATS 5 Trailer
The ATS 5 is large enough to quickly catch motorists’ attention, while still being compact enough to fit on narrow road shoulders and medians. It is ideal for mounting our larger signs (SpeedAlert 24 or InstAlert 24). Use the traffic sign trailer to deliver messages and speed awareness with high visibility in any weather conditions. Beyond their speed feedback and messaging capabilities, they can come equipped with a red and blue violator strobe bar to flash at speeding drivers.

ATS 3 Trailer
The ATS 3 eliminates the need for a permanent pole to mount your smaller radar speed and message signs on. It is ideal for our smaller signs (Shield 12/15, SpeedAlert 18, and InstAlert 18). It is compact and convenient to deploy wherever needed. The pole of the trailer rotates 360 degrees so you can point your sign in any direction. This solution is perfect for resolving neighborhood speeding complaints.

Features All of These ATS Traffic Sign Trailers Have in Common
Radar Message or Variable Message Sign
Each trailer, whether FLEX, ALPR Camera-Ready, or Surveillance-Ready, can come equipped with either an InstAlert variable message board or a SpeedAlert radar message sign making them a traffic sign board as well.
SpeedAlert Radar Message Sign: Combines radar feedback with variable messaging, displaying tailored messages based on drivers’ speeds.

InstAlert Variable Message Sign: Displays up to six screens of custom text, chevrons, and images for versatile communication.

Mobility
Trailers feature a simple manual lever with a lift-assist system for a quick 1-person setup. No special equipment is needed to transport our trailers— they can be towed by any size vehicle with a 2” receiver hitch.
Built to Last
Our trailers are rugged and durable, withstanding harsh weather conditions. The continuous weld steel frame and marine-grade powder coat finish can withstand heavy rain, snow, ice, and extreme temperatures without rusting. Most of our trailers are still in use after 10+ years in the field.
