A crash attenuator is a road safety device designed to absorb impact energy or redirect vehicles away from roadside hazards during a collision. It helps reduce the severity of crashes and protects motorists, roadside workers, and nearby infrastructure. Crash attenuators are commonly installed at the ends of concrete barriers, jersey wall barriers, medians, and other fixed objects where vehicles may collide with exposed edges.

The Delta TL-3 Crash Cushion uses durable steel thrie-beam panels supported by steel diaphragms. During a head-on impact, its panels deform through a controlled process that absorbs energy. The system can also redirect vehicles that strike its side, helping manage impacts from different directions.

The Delta TL-3 Crash Cushion is designed to protect hazardous roadside structures in permanent and temporary traffic applications. It is particularly useful for highways, road construction zones, traffic medians, and other locations where exposed barrier ends create a collision risk.

When installed alongside a concrete barrier, the crash cushion helps protect the exposed end of the barrier from direct vehicle impacts. It can complement concrete jersey barriers, a jersey barrier, or other jersey wall barriers used to separate traffic lanes and protect work areas. The appropriate system depends on the site layout, traffic conditions, and applicable road safety requirements.

The Delta TL-3 offers several practical benefits for road safety and traffic management.

• Impact energy absorption: Steel thrie-beam panels and shear bolts help dissipate impact energy during a collision.
• Vehicle redirection: Its non-gating design helps redirect vehicles that strike the side of the system rather than allowing them to pass through it.
• Quick installation: Its largely pre-assembled design simplifies installation and helps reduce workers' exposure to live traffic during setup.
• Durable performance: The system is designed to perform across a wide range of temperatures and weather conditions.
• Straightforward maintenance: Individual panels and diaphragms can be replaced when damaged, helping simplify repairs.
• Flexible installation: Its directional marker can be adjusted in the field to suit the installation's traffic approach.

The Delta TL-3 is MASH-tested, passed, and eligible at Test Level 3. Proper selection, anchoring, and installation are essential to ensure the system performs as intended.

Whether your project involves highway improvements, temporary traffic control, or roadside infrastructure, selecting the right crash attenuator is an important part of a comprehensive traffic safety plan. Pairing a suitable crash cushion with a concrete barrier or jersey wall barriers can help manage collision risks and improve protection for motorists and road crews.
