Department of Homeland Security Vehicular Terrorism Prevention and Mitigation Act of 2025

H.R. 1608, the Department of Homeland Security Vehicular Terrorism Prevention and Mitigation Act of 2025, would require the Secretary of Homeland Security to produce a comprehensive report on emerging threats and countermeasures related to vehicular terrorism. In coordination with the Transportation Security Administration (TSA) and the Cybersecurity and Infrastructure Security Agency (CISA), the report must assess current and future threats from vehicle-based attacks—especially as technologies like connected and autonomous vehicles, ADAS, ride-sharing platforms, and other automotive tech evolve. It also calls for identifying high-risk locations and events, evaluating preventive measures (from physical barriers to geofencing and cybersecurity), outlining private-sector and law-enforcement coordination, and recommending research and deployment of technologies to deter, detect, and mitigate such threats. The report can be classified, but an unclassified executive summary must be published, and DHS must brief Congress within 30 days of its submission.
