Deflection/Clear Zone

HighwayGuard™ is designed to absorb energy when impacted. When impacted between anchors

deflection occurs. No hazards or obstacles should be in the deflection area such as kerbs, work
materials/equipment.

Vehicle roll should be considered with taller vehicles as these may protrude beyond the barrier
deflection during impact.

Crash Cushions/Other Connections

Crash cushions should be used when impact to either the approach or departure end of a run of

HighwayGuard™

may occur.

Current Crash cushions/ Connections available;

-

Highway Care BG800™ Transition (

MASH Crash tested)

-

QuadGuard CZ (NCHRP 350 Engineered)

-

Tau II (NCHRP 350 Engineered)

An engineered connection is one that has been designed and jointly agreed by Highway Care and
the crash cushion developer as acceptable for use. These may also require approval from relevant
road authorities

–

check road authority approval for guidance on acceptable options available in

your market.

Modifications

No modifications are allowed to HighwayGuard™

components without prior approval from

Highway Care.
