FHWA and AASHTO Release Findings on Dimensions of ET-Plus Guardrail End Terminal

The Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO) have released the findings of a joint task force which evaluated field measurement data collected by FHWA engineers from more than 1,000 4-inch ET-Plus devices installed on roadways throughout the country.

The joint task force concluded that:

• There is no evidence to suggest there are multiple versions (i.e., ET-Plus 4-inch devices with markedly different dimensions) on our nation’s roadways, and
• The end terminals crash tested at the Southwest Research Institute (SwRI) between December 2014 and January 2015 are representative of the devices installed across the country.
