Following a vehicle attack involving a Ford Lightning in New Orleans on New Year’s Day, United States federal law enforcement agencies have issued warnings about the potential for additional vehicle-based terror attacks, reflecting heightened concern about the use of vehicles as weapons in mass-casualty incidents. The warnings underscore the difficult security challenge that vehicle attacks present, as the ubiquity and accessibility of vehicles makes preventing their use as weapons extraordinarily difficult compared to other attack methods.
Vehicle-based attacks have become a persistent security concern globally because of the simplicity and accessibility of the method, which requires no specialized weapons or training and exploits the freedom of movement that vehicles enjoy in public spaces. Protective measures including barriers, vehicle restrictions at major events, and enhanced surveillance have been implemented at high-profile locations, but the fundamental challenge of preventing vehicle attacks remains daunting. The federal warnings reflect the seriousness with which authorities are treating the threat following the New Orleans attack.
