NCHRP 350 Performance at 113 km/h (70 mph)

The QuadGuard HS System has raised the bar in high-speed crash cushion performance by passing the NCHRP 350, TL-3 test matrix for redirective, non-gating crash cushions at the demanding design speed of 113 km/h (70 mph). The system features revolutionary space-frame diaphragms that allow it to provide high-speed impact protection for a wide range of vehicles, from small cars to high-center-of-gravity pickup trucks.

The QuadGuard HS System is the only crash cushion in the world tested to satisfy the stringent FHWA requirements based on NCHRP 350 criteria. During head-on impacts at speeds up to 113 km/h (70 mph), the QuadGuard HS System telescopes, effectively dissipating the energy of both light cars and high-center-of-gravity pickup trucks. During impacts at angles up to 20 degrees, the system redirects the impacting vehicle back into its original travel path.

Tested using NCHRP 350 criteria at 113 km/h (70 mph) Shields hazards up to 914 mm (3'0") wide Majority of components are interchangeable with standard QuadGuard® System Provides 60-70% reusability after design impacts
			Space-frame diaphragms provide high-speed impact protection for a wide range of vehicles.
