H.R. 3629 – PARK IT Act

AI-Generated Summary

Updated February 8, 2026 at 3:47 AM UTC

The PARK IT Act directs the Secretary of Transportation to finish safety rules for vehicles with keyless ignition systems. Within two years, the Department must require manufacturers to add automatic engine shut‑off to stop carbon‑monoxide buildup and to install technology that prevents a vehicle from rolling away when certain safety conditions aren’t met. The rules would apply to most passenger cars and light trucks with internal‑combustion engines, affecting manufacturers and protecting drivers and passengers.

Key Provisions

Require the DOT, within two years, to issue a final rule amending FMVSS 114 so that keyless‑ignition vehicles with combustion engines automatically shut off after an idle period set to prevent carbon‑monoxide poisoning.
Require the DOT, within two years, to issue a final rule mandating roll‑away prevention technology for keyless‑ignition vehicles with automatic transmissions when the vehicle isn’t in park, exceeds a speed limit set by the Secretary, the driver’s seat belt is unbuckled, the service brake isn’t engaged, or the driver’s door is open.
Allow the Secretary to set different idle‑shutdown periods and maximum safe lock‑in speeds based on vehicle type and emissions characteristics.
