ProTx Arresta 100 vehicle arrestor: design and safety notes for roadwork engineers
Reviewed by Joe Ashwell

First reported on Roads & Infrastructure (AU)
30 Second Briefing
Queensland manufacturer ProTx has launched the Arresta 100, claimed as the first purpose-built vehicle arrestor specifically for temporary static roadworks, with a live demonstration at Brisbane’s Advanced Robotics Manufacturing Hub. The system is designed to rapidly slow or stop out-of-control or unauthorised vehicles entering work zones, providing a physical barrier where conventional cones and signage offer limited protection. For road and civil contractors, it signals emerging options for engineered temporary traffic control hardware beyond standard crash cushions and water-filled barriers.
Technical Brief
- System is configured for temporary static roadworks rather than permanent checkpoints or fixed barrier installations.
- Design intent includes interception of both out-of-control and deliberately unauthorised vehicles entering work zones.
- Physical arrestor provides a positive barrier layer beyond reliance on driver compliance with traffic control devices.
- Likely integration with existing temporary traffic management plans and Method of Working Plans for urban roadworks.
- Deployment has implications for updating temporary traffic control standards and pre-start safety briefings on civil sites.
Our Take
Queensland-based infrastructure safety products are relatively sparse in our 842-piece Infrastructure set, so ProTx’s Arresta 100 positions Brisbane as a small but visible node for locally developed road-safety hardware rather than just project delivery.
ARM Hub’s involvement signals that advanced manufacturing and robotics capabilities are starting to be applied to roadside safety hardware in Australia, which could make it easier for transport agencies in Queensland and other states to specify higher-performance, locally supported arrestor systems in future projects.
