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

This bill focuses on stopping vehicle-based attacks, like someone using a car or truck to harm people. It tells the Department of Homeland Security (DHS) to study current and new threats (including risks from self‑driving and connected cars, ADAS features, and ride‑share platforms) and report back to Congress within 180 days, working with TSA and CISA. The report will be classified, but DHS can post a short public summary online so communities can understand the main findings. The plan includes looking at higher‑risk places—airports, hospitals, government sites, parades, concerts, sports events, city centers, and other crowded spaces—and suggesting ways to protect them, like barriers, geofencing, vehicle‑stopping tools, better cybersecurity for cars, and clear response plans for emergencies. DHS must also coordinate with local police and first responders, offer training (including for smaller towns), and work with rental and ride‑share companies and car makers—while taking privacy and civil rights into account when using new tech and AI. Overall, it’s meant to organize a national plan to prevent and respond to vehicular terrorism and share the key takeaways with the public.

• When: DHS must deliver the report within 180 days of enactment and brief Congress within 30 days after that; a public executive summary may be posted online .
