The Federal Highway Administration (FHWA) Office of Safety Research and Development conducted a pilot ISPE of the most widely used energy absorbing guardrail end terminals (GETs) in the United States, specifically: ET-Plus, ET-2000, Flared Energy Absorbing End Terminal (FLEAT), Slotted Kinking Terminal (SKT), Manual for Assessing Safety Hardware Slotted Kinking Terminal (MSKT), X-Lite, X-Tension, and Soft Stop.

Data were collected at test sites in four States that have agreed to participate in this pilot study: Massachusetts, Pennsylvania, California, and Missouri. This work is being done in cooperation with the National Highway Traffic Safety Administration (NHTSA), the Resource Center's Safety Technical Services Team, the Office of Safety and the division offices in each of the data collection States. The study did not collect data across the entire State. The pilot study only collected data in a few State-selected regions. For more information about this study, go to the main ISPE Resources page.
