Why Choose the TMA Max?

The TMA Max isn’t just about meeting safety standards—it’s about exceeding them with a fully-loaded package tailored for maximum productivity and protection. At its core, the Scorpion II TMA TL-3 provides full-width impact protection with patented curved aluminum tube frames that redirect errant vehicles away from the truck’s vulnerable “coffin corners,” minimizing crash severity. The energy-absorbing honeycomb core, encased in durable powder-coated aluminum modules, dissipates collision forces in progressive stages, ensuring both worker safety and cost-effective repairs.

What sets the TMA Max apart is its focus on the crew. The 60” wide man buckets offer ample space for workers to operate comfortably and securely, a standout feature that enhances efficiency when setting up cones or signs in high-speed zones. Hydraulically powered deployment makes it quick and easy to shift between travel and work modes, while its compact 12’ 10” deployed length—the shortest among MASH TL-3 TMAs—reduces incidental impacts and keeps your fleet agile.

Western Highways Traffic Truck Products takes it further with customizable extras: think advanced LED lighting for night operations, camera systems for real-time monitoring, or additional storage racks for tools and equipment. With the West Coast’s largest TMA inventory and a reputation for fast build-to-order service, we tailor each TMA Max to your exact needs—whether you’re renting, buying, or leasing. It’s not just a truck; it’s a lifeline for your team, backed by our commitment to quality and compliance with state and federal regulations.

Performance

The TMA Max is built to perform where it counts. Its Scorpion II TMA TL-3 features an open cartridge design that cuts wind resistance and boosts fuel efficiency—ideal for long highway hauls or extended deployments. The modular construction means only damaged sections need replacement after an impact, keeping repair costs low and downtime minimal. Integrated LED brake, directional, signal, and running lights enhance visibility, providing advanced warning to drivers day or night.

The 60” man buckets are a game-changer, offering a wider platform than typical options (often 38” wide), reducing worker fatigue and improving safety during traffic control setups. Optional upgrades like the Doctor Air Brake® system can lock the host vehicle’s brakes instantly upon impact, adding an extra layer of protection for the driver, impacting vehicle occupants, and nearby workers. This isn’t just a TMA—it’s a comprehensive safety ecosystem designed for the real world.
