As a business owner operating a massive fleet of highway safety vehicles, I see the harsh reality of our roads every single day. Our crews put their lives on the line just to maintain the infrastructure we all rely on.
We send our teams out into active work zones with the best equipment available. But the environment they face is becoming increasingly hostile.
The statistics from the past two years are absolutely staggering. We have seen a massive spike in work zone intrusions across the country.
Specifically, TMA truck hits are up 47% since 2024. This is not just a random fluctuation in traffic data. It is a terrifying trend that demands immediate attention from every fleet operator and daily commuter.
Today, I want to pull back the curtain on what is really happening out there. We’ll look closely at dashcam data to understand why drivers are crashing into highly visible safety trucks.
UNDERSTANDING THE ROLE OF A TMA TRUCK
Before we look at the crash data, you need to understand what a TMA truck actually does. TMA stands for Truck Mounted Attenuator.
These heavy-duty vehicles have a massive crash cushion attached to the rear. We park these trucks at the beginning of a highway work zone.
Their entire purpose is to act as a physical shield for the road workers ahead. If a civilian driver fails to merge and enters the work zone, they hit the TMA truck instead of the vulnerable crew members.
- TMA trucks absorb the kinetic energy of a high-speed impact.
- They prevent civilian vehicles from penetrating the active work area.
- The crash cushion crumples strategically to save the life of the impacting driver.
- They are heavily weighted to prevent being pushed forward into the crew.
At SPA Safety Systems, we build and maintain these lifesavers. We know exactly how much engineering goes into making them effective.
THE STAGGERING 47 PERCENT INCREASE
When we look at the data from 2024 to 2026, the numbers are deeply concerning. A 47% increase in rear-end collisions with TMA trucks is unprecedented.
You might wonder how someone can miss a massive truck covered in reflective tape and flashing strobe lights. These vehicles are designed to be the most visible objects on the highway.
Yet, nearly every other day, we get a report of another impact. The frequency of these crashes is putting immense strain on safety fleets nationwide.
Replacing these attenuator cartridges costs a fortune. More importantly, the psychological toll on the drivers inside these TMA trucks is severe.
WHAT THE DASHCAM DATA ACTUALLY SHOWS
Every modern TMA truck in our fleet has high-definition dashcams. We have forward-facing, rear-facing, and cabin-facing cameras.
When an impact occurs, we pull the footage immediately. We analyze the seconds leading up to the crash to understand the driver’s behavior.
The dashcam data tells a very clear and very disturbing story. Most of these impacts are not caused by bad weather or mechanical failures.
Severe driver distraction causes them. The footage shows drivers making absolutely no attempt to brake or swerve before hitting a stationary truck at 70 miles per hour.
THE SMARTPHONE EPIDEMIC ON OUR HIGHWAYS
Our rear-facing cameras reveal the number one culprit: smartphone use. We can literally see the glow of the screen on the driver’s face right before the impact.
People watch videos, scroll through social media, and type long messages while operating heavy machinery at highway speeds. It is a recipe for absolute disaster.
- Drivers are looking down at their laps for five to ten seconds at a time.
- At 70 mph, a car travels over 100 feet per second.
- A five-second distraction means driving the length of a football field completely blind.
- By the time they look up, the TMA truck is right on their bumper.
This level of distraction completely negates the flashing arrow boards and warning signs we place miles ahead of the work zone.
THE FALSE SENSE OF SECURITY FROM ADAS
Another alarming trend we see in the dashcam footage involves Advanced Driver Assistance Systems. Many modern cars have lane-keeping assist and adaptive cruise control.
Drivers are treating these assistance features like fully autonomous driving systems. They take their hands off the wheel and their eyes off the road.
The problem is that these systems often fail to recognize stationary objects in a closed lane. The radar might track the car ahead, but if that car swerves to avoid the TMA truck, the system gets confused.
The dashcam shows the lead car merging safely, while the trailing car plows directly into our attenuator without ever braking.
THE PHYSICS OF A HIGH-SPEED IMPACT
When a civilian vehicle hits a TMA truck, the physics involved are incredibly violent. The attenuator is designed to crush and fold, absorbing the massive kinetic energy.
This controlled deformation is what keeps the civilian driver alive. Without the TMA, that car would hit a heavy construction vehicle or a group of workers, resulting in guaranteed fatalities.
Our dashcams capture the sheer force of these collisions. The impact lifts the rear of the TMA truck off the ground, despite its weight of thousands of pounds.
- The attenuator cartridge compresses in milliseconds.
- Energy is dispersed laterally and downward to prevent the truck from rolling.
- The host truck is pushed forward, which is why we maintain a strict roll-ahead distance.
- The civilian vehicle is typically totaled, but the cabin remains intact.
Seeing this footage reinforces exactly why we do what we do at SPA Safety Systems. These trucks are non-negotiable for highway operations.
THE FINANCIAL IMPACT ON FLEET OWNERS
As a business owner, dealing with a 47% increase in hits is a logistical nightmare. Every time a TMA is hit, that truck is instantly out of commission.
We have to dispatch a replacement truck immediately to keep the work zone secure. Then we have to tow the damaged truck back to our 19,200-square-foot facility in Flanders, New Jersey.
Replacing a crushed attenuator cartridge costs tens of thousands of dollars. While insurance covers the hardware, the downtime hurts our operational efficiency.
This is why we constantly stress the importance of having a robust backup fleet. You cannot afford to leave your highway crews unprotected for even an hour.

TRAINING CREWS FOR WORK ZONE SAFETY
Having the best TMA truck is only half the battle. You also need highly trained operators who understand work zone dynamics.
The driver sitting inside the TMA truck has a very dangerous job. They must brace for potential impacts while monitoring traffic flow behind them.
We always advise our clients to implement strict safety protocols. The TMA truck must be parked at the correct roll-ahead distance from the active crew.
If the truck is parked too close, a high-speed impact could push it right into the workers. Proper spacing is a matter of life and death.
THE CRITICAL ROLE OF ARROW BOARDS AND MESSAGE BOARDS
Visual communication is our first line of defense against distracted drivers. Long before a driver reaches the TMA truck, they need to know the lane is closed.
That is why we also supply top-tier arrow boards and message boards. Deploy these units miles ahead of the actual work zone.
Dashcam data shows that early warning systems work for drivers who are actually looking at the road. Clear, bright instructions give them time to merge safely.
- Deploy message boards at least two miles ahead of the closure.
- Use clear and concise text that can be read at highway speeds.
- Ensure all LED panels are fully functional and free of dead pixels.
- Combine arrow boards with strategically placed cone tapers.
At SPA Safety Systems, we provide the boards and cone trucks needed to create a comprehensive traffic control plan.
WHY CONE TRUCKS ARE ESSENTIAL
Setting up a work zone takes careful coordination. You cannot just throw cones out of the back of a standard pickup truck.
You need specialized cone trucks designed for efficiency and safety. These trucks have custom racks and low-riding platforms that help workers deploy traffic control devices quickly.
Our cone trucks support safer, more organized roadway operations. They keep the workers protected while they establish the lane closure.
Once the cones are set, the TMA truck moves into position to lock down the lane. This precise tactical maneuver requires the right equipment.
SCISSOR LIFT AND HI RAIL TRUCKS
Highway safety goes beyond just paving and painting. Much infrastructure work happens above the road or on railway tracks.
That is why our fleet includes versatile scissor lift trucks. These are designed for elevated roadway and maintenance work, like repairing overhead signs or bridge structures.
We also offer dependable Hi Rail trucks. These are dual-purpose vehicles built for railway maintenance. They can drive on the highway and then deploy steel wheels to ride on the train tracks.
- Scissor lift trucks provide a stable platform for high-altitude repairs.
- Hi Rail trucks offer unmatched versatility for infrastructure operations.
- Bucket trucks ranging from 36 to 70 feet are available for utility work.
- All our specialized trucks undergo the same rigorous safety checks as our TMAs.
No matter what kind of infrastructure project you are tackling, SPA Safety Systems has the exact vehicle you need to get it done safely.
THE FUTURE OF HIGHWAY LEGISLATION
The 47% increase in TMA hits is pushing state and federal agencies to take action. We need stricter legislation to combat distracted driving in work zones.
Many states are now implementing automated speed enforcement cameras in construction zones. If you speed past a TMA truck, you automatically get a massive fine in the mail.
As fleet owners, we fully support these legislative measures. We need severe consequences for drivers who put our crews at risk.
Until the laws catch up with the technology, we’ll keep relying on heavy steel and engineered crash cushions to protect our people.
