Vehicle Ramming Mitigation Resources
CISA's Vehicle Ramming Self-Assessment Tool
CISA’s Vehicle Ramming Self-Assessment Tool was developed in partnership with the Chicago Police Department to assist critical infrastructure owners and operators and federal, state, and local law enforcement agencies with evaluating areas of interest against the risk of a vehicle-ramming style of attack. It’s a web-based resource comprised of a series of simple questions that evaluate various components of a facility to assess potential vulnerabilities to a vehicle ramming attack. Based on responses, the tool provides recommended actions to reduce risk; it also includes access to a multitude of informational resources.
Accompanying the tool are a One-Page Overview and User Guide with instructions on how to operate the tool.
Vehicle Ramming Attack Mitigation Video

- American Society of Testing and Measures, Standard Test Method for Crash Testing of Vehicle Security Barriers: This Standard Test Method for Crash Testing of Vehicle Security Barriers provides a range of vehicle impact conditions, designations, and penetration performance levels. This will allow an agency to select passive perimeter barriers and active entry point barriers appropriate for use at facilities with a defined moving vehicle threat.
- Chicago Department of Transportation - Rules and Regulations for Construction in the Public Way: Effective management of this public space is vital for sustainable transportation and infrastructure, as well as for residents and local businesses.
- FBI Vehicle Rental Vehicle Ramming Video: The FBI, DHS, and TSA—in coordination with the Truck Renting and Leasing Association and the American Car Rental Association—have released a short training video to help vehicle rental employees identify suspicious activities and behavior by customers who may wish to use a rented vehicle for nefarious purposes.
- G4S - Vehicular Terrorism: The Threat Behind the Wheel (.pdf, 2.042KB): Recent vehicular attacks in France and Germany clearly highlighted the viability of vehicle ramming as a legitimate terrorist tactic and one that should be a focus for law enforcement, especially during special event planning. These attacks vividly demonstrate how challenging it can be to stop a vehicular attack once it has been launched.
- Health and Safety Executive, Managing Crowds Safely: A Guide for Organizers at Events and Venues (.pdf, 672 KB): This booklet aims to provide practical guidelines on managing crowd safety in a systematic way by setting out an approach which can be utilized by organizers of any event or venue. The venue may be used regularly, (e.g., shopping centers and sports grounds, or occasionally (e.g., fireworks displays and agricultural shows). The guide is aimed at organizers but will also be of interest to venue staff and contractors.
- National Capital Planning Commission, Designing and Testing of Perimeter Security Elements (.pdf, 1,955 KB): While protecting important public and private buildings is a legitimate need in the United States, that need has too often been dealt with by the placement of unsightly barriers that detract from the public space and create a fortified atmosphere. A major challenge that planners and designers in Washington face today is to develop effective perimeter security measures that respect existing dramatic views, gracious open spaces, and the city’s historic urban design. he plan proposes an expanded palette of attractive furnishings and landscape solutions to guard against the threat posed by bomb-laden vehicles while preserving the open space qualities of the capital’s urban design. Built on an urban design framework that identifies key areas and streets within Washington.
- New York City Pedestrian Level of Service Study, Phase I (.pdf, 3,255 KB): The objectives of this study are to evaluate the Highway Capacity Manual (HCM) pedestrian Level of Service (LOS) methodology in terms of its suitability for pedestrian planning in New York City, to compile a pedestrian characteristics database, and to make recommendations for changes in pedestrian LOS analysis in New York City.
- New York Department of Transportation, Highway Design Manual Chapter 10: Roadside Design, Guide Rail, and Appurtenances: This chapter also provides guidance for assessing existing facilities to determine the number of safety concerns and nonconforming features that are present in the roadside area and the amount of upgrading that would be appropriate when work is performed on that existing facility.
- Site and Urban Design for Security: Guidance against Potential Terrorist Attacks (.pdf, 38 MB): This publication focuses on site design aimed to protect buildings from attackers using vehicles carrying explosives. These represent the most serious form of attack. Large trucks enable terrorists to carry very large amounts of explosives that are capable of causing casualties and destruction over a range of many hundreds of yards. Perimeter barriers and protective design within the site can greatly reduce the possibility of vehicle penetration. Introduction of smaller explosive devices, carried in suitcases or backpacks, must be prevented by pedestrian screening methods.
