TMA Trucks
Protecting Lives, Safeguarding Roads
What is a TMA Truck?
Truck Mounted Attenuator (TMA) truck is equipped with a crash attenuator mounted at its rear, specifically designed to enhance safety in work zones. By absorbing the force of collisions, the attenuator functions as a protective cushion, effectively minimizing the severity of crashes and safeguarding both roadside workers and drivers.
Core Functionality
TMA trucks function as mobile safety barriers, seamlessly offering a protective shield essential for roadway construction, maintenance, and traffic management operations.
Impact Mitigation
These trucks are meticulously engineered to redirect or halt errant vehicles, effectively minimizing the risk of injuries and significantly reducing damage.

How TMA Trucks Protect and Whom They Protect
Truck Mounted Attenuators trucks serve as vital safety barriers, purpose-built to safeguard both roadside workers and drivers in hazardous environments. By absorbing and dispersing the kinetic energy of vehicle collisions, these trucks play a pivotal role in minimizing injuries and damage, making work zones significantly safer.
How TMA Trucks Protect
1. Impact Absorption
At the core of every truck is a crash cushion strategically mounted at the rear. This cushion is specifically engineered to crumple upon impact, effectively absorbing collision forces. By reducing the energy of the crash, it prevents secondary impacts, protecting everyone involved.
2. Vehicle Redirection
In addition to absorbing impacts, TMAs are designed to redirect errant vehicles away from hazardous zones. This feature helps to mitigate the risk of additional collisions and ensures that vehicles are steered clear of workers and equipment.
3. Visual Deterrence
Equipped with high-visibility LED arrow boards, reflective panels, and warning signs, TMAs are not only functional but also serve as a powerful visual deterrent. These features alert oncoming drivers to reduce speed and navigate safely around the work zone, preventing potential accidents before they occur.
Whom TMAs Protect
1. Roadside Workers
TMA trucks act as a physical shield, creating a protective barrier between oncoming traffic and construction crews. This dramatically reduces the risk of injuries and fatalities, ensuring a safer working environment for everyone on-site.
2. Drivers
By absorbing crash forces, TMA trucks significantly decrease the severity of injuries for drivers and passengers involved in accidents. They transform what could be a catastrophic collision into a manageable situation, often saving lives in the process.
3. Equipment and Assets
In addition to protecting people, TMA trucks safeguard expensive roadwork machinery and minimize disruptions to ongoing projects caused by accidental intrusions. This helps keep projects on schedule while reducing repair and replacement costs.
Why these Are Critical
Every single day, TMA trucks save lives by providing a robust safety net in unpredictable and high-risk traffic conditions. Their presence not only ensures safer work zones but also helps reduce the severity of accidents. Furthermore, they reinforce compliance with regulatory safety standards, making them an essential component of modern traffic management and roadway maintenance operations.
TMA trucks are more than just equipment—they are a commitment to protecting lives and creating safer environments for workers and motorists alike.
Regulations Guides
TMAs trucks are critical for maintaining safety in work zones, but their usage is subject to state-specific regulations. These regulations define the guidelines for TMA deployment, required impact ratings, and compliance with nationally recognized safety standards, such as MASH (Manual for Assessing Safety Hardware) or NCHRP 350. Adhering to these standards ensures optimal performance and safety in every work zone.
