What is the story behind the Armadillo truck mounted attenuator?

The Armadillo truck mounted attenuator was developed by Verdegro, a Netherlands-based traffic safety manufacturer founded in 2003. The name “Armadillo” reflects the product’s core design philosophy: just as the armadillo uses its tough, layered shell to absorb and deflect danger, this crash cushion is built to absorb high-energy impacts and protect workers in active road zones. Below, we answer the most common questions about how the Armadillo TMA works, what sets it apart, and where it is used.

Who developed the Armadillo truck mounted attenuator?

The Armadillo TMA was developed by Verdegro, a traffic safety manufacturer based in Bergen op Zoom, the Netherlands. We have been engineering mobile traffic safety systems since 2003, and the Armadillo is one of our core crash protection products designed specifically for use on trucks operating in live traffic environments.

The name was chosen deliberately. The armadillo is an animal known for its hard, scale-like shell that shields it from predators, even scorpions. We use the same principle in the product’s engineering: a strong, structured crash cushion that can absorb a serious impact and keep the operator and road crew behind it safe. The design prioritizes real-world reliability over complexity, which is a philosophy that runs through everything we build.

The Armadillo sits within a broader portfolio of crash protection systems that includes the VanGuard TMA, the world’s first truck mounted attenuator designed for closed vans. Together, these products reflect our long-standing focus on practical, tested, and compliant safety equipment for road maintenance professionals.

What makes the Armadillo TMA different from other attenuators?

The Armadillo TMA stands out from other truck mounted attenuators through its upright transport design, single-stage deployment, and mechanical simplicity. These three features combine to make it faster to deploy, easier to maintain, and more practical in constrained work zones compared to many competing systems on the market.

Upright transport design

Most truck attenuators fold flat during transport, which reduces height but blocks access to the truck’s flatbed. The Armadillo takes a different approach. In transport mode, it stands upright at 3,940 mm (12.9 ft), leaving the entire flatbed completely clear. This means operators can carry additional equipment, tools, or materials without any obstruction, a meaningful practical advantage for road maintenance crews who use their vehicles for multiple tasks throughout a shift.

Single-stage deployment and mechanical simplicity

The Armadillo deploys in a single continuous motion in less than 20 seconds, even while the vehicle is moving at up to 80 km/h (50 mph). There are no secondary extension stages, which reduces mechanical complexity and the risk of deployment failure. The system operates without sensors or electronic feedback systems, relying instead on a straightforward hydraulic mechanism with two rams for raising and lowering the cushion. This design eliminates a significant source of potential failures and makes the system far easier to maintain in demanding field conditions.

With an overall width of 2,300 mm (7.5 ft), the Armadillo also maintains a compact footprint that allows it to operate in narrow lanes and tight work zones without excessive overhang. It offers the shortest possible turning circle in its class, which matters when maneuvering in restricted road environments.

How does the Armadillo truck mounted attenuator work in a crash?

In a crash, the Armadillo TMA absorbs the kinetic energy of an errant vehicle by deforming in a controlled way, redirecting the impacting vehicle and dramatically reducing the force transferred to the host truck and the workers behind it. The aluminum crash cushion is the primary energy-absorbing element, engineered to collapse progressively on impact.

The system is mounted to the rear of a support truck weighing between 7,228 kg and 12,475 kg (approximately 15,935 to 27,502 lbs). When a vehicle strikes the attenuator, the cushion absorbs and dissipates the crash energy rather than transferring it rigidly through the truck’s structure. Integrated underride protection is built directly into the steel framework, preventing an impacting vehicle from sliding beneath the system, a common cause of severe injury in road collisions.

The hydraulic components and electronics are enclosed in a sealed, protective housing, which keeps the system functional after minor impacts and reduces environmental exposure. Because the hydraulic rams are positioned away from the crash zone, there is no risk of oil leaks during or after an impact, an important consideration for both environmental compliance and post-incident safety.

After a crash, the aluminum cushion can be inspected and, if necessary, replaced or refinished. It can be delivered in any RAL colour to meet local road authority specifications.

What safety standards does the Armadillo TMA meet?

The Armadillo TMA is fully crash tested and approved according to MASH 2016 TL-3, the most current US safety standard for truck mounted attenuators. It also holds approval under the UK optional 110K test (TD49/07), making it compliant for deployment in British road environments. The system is delivered with official crash test certifications and carries CE marking and EMC compliance.

MASH 2016 (Manual for Assessing Safety Hardware) is the benchmark standard set by the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA). TL-3 certification covers impacts from vehicles traveling at highway speeds, which is the most demanding performance category for attenuators used on high-speed roads. The Armadillo has been tested across multiple MASH test designations: 3-50, 3-51, 3-52, 3-53, and the optional 3-54.

Beyond crash performance, the system also supports geofencing integration through platforms such as Waze, Flitsmeister, Apple Maps, and Here, allowing the attenuator’s position to be broadcast to approaching drivers as an active safety alert.

Where is the Armadillo truck mounted attenuator used?

The Armadillo TMA is used in active road work zones where a moving or slow-moving truck needs to protect workers and equipment from rear-end vehicle impacts. Typical deployments include highway maintenance operations, lane closures, resurfacing projects, incident management, and any situation where a shadow vehicle is required to absorb errant traffic.

Because it meets both MASH 2016 TL-3 and the UK TD49/07 standard, the Armadillo is suited for deployment across multiple international markets. It is used by highway construction companies, road maintenance contractors, municipal transportation departments, and government agencies responsible for managing traffic safety in work zones.

The compact width of 2,300 mm makes it practical for use in narrower European road configurations, while the MASH certification makes it equally viable for North American highway projects. The system’s support truck weight range, from 7,228 kg to 12,475 kg, covers a broad class of commercial vehicles commonly used in road maintenance fleets, giving fleet managers flexibility when specifying the host vehicle.

Optional accessories such as MASH-approved arrow board brackets, multi-truck brackets, jockey wheels, and reflective foil chevrons (to local country specifications) allow the Armadillo to be configured for specific national road authority requirements, further extending its range of deployment contexts.
