FHWA Review of ET-Plus

RETESTING OF THE ET-PLUS

In October 2014, FHWA requested that Trinity arrange for crash testing of the 4-inch ET-Plus at an independent, accredited test laboratory. The tests were conducted at Southwest Research Institute (SwRI) – a certified independent lab – in December 2014 and January 2015. The purpose of the tests was to "reset" the baseline to ensure that the ET-Plus complies with the crash test criteria that are applicable to this device—the NCHRP-350 testing criteria—criteria that have been applied to roadside safety hardware from 1993 to 2011 and to which a majority of roadside safety devices on the Nation’s roadway system currently comply.

8 crash tests took place:

FHWA worked to ensure the integrity and transparency of the ET-Plus retesting:

SwRI, FHWA and Dr. Gabler each independently evaluated the crash test results. Each independently concluded that the ET-Plus meets the NCHRP 350 criteria at both the 27.75-inch and 31-inch height.

We have posted the test results, findings, and related information below so that anyone wishing to compare the crash test data against the standards applicable to the device may have the benefit of the full and complete data set.
