Quest Impact Attenuator System

The QUEST System is a simple redirective, non-gating crash cushion that has been completely tested and has successfully passed the entire NCHRP 350 test matrix at test levels two and three. The 70mph Quest System has been tested and accepted by the FHWA after successfully passing NCHRP 350 test 3-31. The QUEST System consists of a series of W-beam fender panels supported by diaphragms with an innovative integrated trigger mechanism at the nose that releases a “front assembly” during impacts to absorb the energy of impact. The system is designed to telescope rearward during head-on impacts to absorb the energy of such an impact and to redirect vehicles during side angle impacts. The system provides protection for hazard widths ranging from 24”-36”.
