Innovating Vehicle Arresting Barrier Systems.
Designing and deploying high-performance vehicle arresting barrier systems that safely stop runaway trucks and errant vehicles
CatchNet® is a mechanical runaway truck arresting system engineered for locations where traditional gravel escape ramps cannot be constructed. Using high-strength energy-absorbing nets, CatchNet safely decelerates heavy vehicles in a controlled distance.
FlexNet® is a flexible vehicle arresting barrier designed for reversible lanes, managed lanes, and dynamic traffic control environments. The system deploys and retracts rapidly while maintaining the strength required to arrest out-of-control vehicles that enter restricted or opposing lanes.
HOV Lane Solutions
TrainGuard® is a high-performance net-based vehicle arresting system designed to prevent errant highway vehicles and busses from entering active rail corridors at high-speed rail crossings, hazardous materials routes, and other sensitive rail-adjacent locations.

What is a Vehicle Arresting Barrier?
A vehicle arresting barrier system is a purpose-built safety solution designed to stop or slow uncontrolled vehicles in a predictable, controlled manner. These systems are commonly used on steep mountain grades, emergency escape ramps, reversible traffic lanes, industrial roadways, ports, rail corridors, and other high-risk environments where traditional barriers or truck escape ramps are not feasible.
Arresting Barrier systems use engineered energy-absorbing components, including high-strength nets, structural towers, and controlled deceleration zones, to safely arrest vehicles weighing up to 90,000 pounds without catastrophic impact forces. The result is a safer outcome for drivers, first responders, surrounding traffic, and infrastructure.

Vehicle Arresting Barrier Are All Around Us.
For more than 50 years, vehicle arresting systems have been used to safely stop errant vehicles by transforming uncontrolled impacts into predictable, energy-absorbing events. Deployed on steep grades, rail crossings, mining haul roads, and in temporary traffic control environments such as festivals and parades, these engineered systems provide protection in locations where traditional roadway barriers are not enough.

About
Vehicle Arresting Barrier and Truck Escape Ramp Systems
Impact Technologies designs vehicle arresting barrier (VAB) and truck emergency escape ramp (TEER) systems that provide controlled vehicle stopping across modern transportation environments. These systems use energy-absorbing engineering and controlled deceleration technology to safely capture vehicles when roadway safety depends on reliable stopping performance.
Our engineering work began with truck escape ramp systems for runaway truck protection on steep mountain highways and expanded into a broader approach to vehicle arresting barrier technology. Every system is designed to deploy efficiently, store compactly, and deliver consistent vehicle capture and deceleration within a controlled stopping distance.
Vehicle Arresting Barrier Applications
Impact Technologies vehicle arresting barrier systems are installed across North America supporting multiple roadway safety applications, including:
• Truck escape ramps on steep mountain grades and freight corridors
• Managed lane access control and HOV lane enforcement systems
• Roadway closures for major public events and pedestrian protection
• Work zone vehicle protection on active highways
• Infrastructure protection for rail crossings, bridge openings, and restricted roadway access
The CatchNet truck escape ramp system provides runaway truck protection on steep grades and mountain corridors. The FlexNet vehicle arresting barrier system supports controlled vehicle stopping for managed lane access and roadway closures. The RailGuard vehicle arresting barrier provides protection for Class 7 rail crossings and transportation infrastructure environments.
Event Security and Roadway Closure Safety
For road closures at major public events, the Impact Technologies vehicle arresting barrier system has been reviewed by the National Transportation Safety Board (NTSB) for this application. Transportation agencies and event planners rely on vehicle arresting barrier systems to provide controlled vehicle stopping capability where pedestrian safety and roadway protection are essential.
Impact Technologies vehicle arresting barrier technology also protects mining haul roads, secures median bridge openings over rivers and rail corridors, and provides reliable vehicle stopping systems for transportation safety environments where controlled deceleration and capture are required.
Impact Technologies designs and deploys vehicle arresting barrier systems, truck emergency escape ramp systems, managed lane vehicle barriers, and deployable roadway closure barriers supporting transportation safety infrastructure throughout North America.
Real Stories. Real Saves.
Truck caught by the CatchNet
One Of Wyoming’s 2 ‘Catchnet’ Systems Saves Driver Of Runaway Truck On Teton Pass
One of Wyoming’s two “catchnet” systems to stop runaway vehicles saved the driver of a box truck that lost its brakes on Teton Pass on Thursday. The catchnet uses a series of energy-absorbing nets that can slow and stop high-speed and heavy vehicles.
Box truck stopped by Teton Pass catchnet truck arrestor on Thursday
A truck on Teton Pass lost its brakes and used the catchnet arrestor system to stop on Thursday, July 17.
Runaway truck ramp on Teton Pass makes two big saves
Two runaway vehicles on the Teton Pass have successfully been halted this month by the truck arrestor system, according to the Wyoming Department of Transportation (WYDOT).
WYDOT to begin working on retrofitting US16 CatchNET runaway truck syste
The Wyoming Department of Transportation Commission awarded S&S Builders of Cheyenne a $1.4 million contract to retrofit the runaway truck system on US 16 west of Buffalo at mile marker 85.40. Work will begin the week of May 29 and is scheduled to be completed by September 30, 2023.
Runaway Truck Escape Ramp in Garden City Opens
Cable barrier system to enhance safety on U.S. 89 A new truck escape ramp opened in October 2020 on U.S. 89 west of Garden City. The catch-net cable system was new to Utah and uses a series of cable nets to stop runaway semi-trucks coming out of Logan Canyon
New Truck Arrestor System Prevents Potentially Deadly Crash On Teton Pass
A newly opened truck arrestor system worked just as it is intended earlier this month—preventing a potentially deadly crash on Teton Pass. At about 5 p.m. on Friday, June 2, 2017, Jackson, Wyo. resident Andrew Williams was traveling over Teton Pass on a return trip from Idaho where his 1992 Ford Econoline bus had been at a shop. Williams lost control of his brakes over the pass, but his quick thinking saved the day.
Understanding Flex Lanes
Flex lanes operate as an additional two-lane roadway that carries one direction of traffic at a time and can alternate between north- and southbound depending on the greatest need due to capacity. The flex lanes are scheduled to open to travelers in Fall 2025.
First truck arrestor ramp for Virginia opens on U.S. 250
Today, a new truck arrestor ramp opens on U.S. 250 (Rockfish Gap Turnpike), and it’s the first of its kind in Virginia. This $5.5 million safety feature is designed to put the brakes on runaway big rigs and passenger vehicles descending Afton Mountain.
