Vehicle Barrier Resources

The Department of State has been working with the Department of Defense Combatting Terrorism Technical Support Office – Technical Support Working Group (CTTSO/TSWG) on a vehicle barriers project with three distinct elements:

  • An application guide that provides practical selection and application advice when the decision to use a vehicle barrier has been made.
  • A model procurement specification, based on that used by the Department’s Office of Overseas Operations, which facilitates the crafting of a comprehensive procurement document.
  • Market research in a spread sheet that allows a potential consumer to evaluate the plethora of commercially available barriers in a searchable format. Note: The products offered are to be used for informational purposes only to assist with Active Vehicle Barrier specification and selection processes. Department of State and TSWG have not established any new standards through these documents. Existing standards included are cited as such. Department of State and TSWG do not endorse any model or manufacturer included in these products.
