In high-speed work zones, the Truck-Mounted Attenuator (TMA) is often the final critical barrier protecting roadway workers from errant vehicles. Among the many TMA options available, the Scorpion II TMA TL-3 consistently stands out as a top performer in safety, reliability, and real-world durability.
Western Highways Traffic Safety is an authorized dealer and certified installer of the Scorpion II TMA TL-3. Having equipped and supported hundreds of these units across California, we’ve seen firsthand why this system has become a preferred choice for professional traffic control contractors who demand the highest level of protection.
This article explores the engineering, performance, and practical advantages that make the Scorpion II TL-3 model stand out in demanding work zone environments.
Full MASH TL-3 Certification: Proven Crash Protection
The Scorpion II TMA TL-3 is fully tested and accepted under the rigorous Manual for Assessing Safety Hardware (MASH) 2016 at Test Level 3 — the current national standard for high-speed roadways (55 mph and above).
What TL-3 Certification Delivers:
- Successful performance in 62 mph small car and 70 mph pickup truck crash tests
- Controlled energy absorption that minimizes risk to vehicle occupants
- Excellent vehicle trajectory control with minimal underride or vaulting
- Strong structural integrity under high-impact forces
This certification gives contractors and agencies confidence that the system will perform as designed when a crash occurs.
Advanced Engineering Features
Multi-Stage Energy Absorption System The Scorpion II uses a sophisticated aluminum honeycomb cartridge design with progressive crush zones. This allows it to absorb impact energy in a controlled, staged manner — reducing sudden deceleration forces while bringing the vehicle to a safe stop within the attenuator’s length.
Robust Mounting and Structural Design The TMA mounts securely to the host truck with reinforced brackets and precision alignment. This ensures stability during normal driving and reliable performance during an impact event.
Integrated High-Visibility Arrow Board The system features a large, bright LED arrow board with multiple display patterns and auto-dimming technology. This provides excellent visibility during both day and night operations without creating dangerous glare for oncoming traffic.
Reliable Hydraulic Deployment Smooth, fast deployment and stow capabilities with redundant safety locks. The system transitions quickly between travel and work positions, supporting efficient operations.
Durable Construction for California Conditions Built with corrosion-resistant materials and protective coatings, the Scorpion II stands up well to coastal salt air, Central Valley heat and dust, and frequent highway use.
Real-World Performance Advantages
Contractors using the Scorpion II TL-3 report consistent benefits:
- Superior impact protection in documented high-speed collisions
- Reduced maintenance needs compared to older systems
- Easier compliance with Caltrans and local agency inspections
- Greater operational flexibility for day and night projects
- Better overall fleet reliability and uptime
These advantages translate into safer work zones, fewer project delays, and lower long-term equipment costs.
