HB 1166 Missouri House · 2025 Regular Session

Establishes provisions relating to autonomous vehicles

HB 1166 establishes legal rules for fully autonomous vehicles (level 4/5 systems) operating without human drivers in public roads. It requires these vehicles to achieve a "minimal risk condition" during system failures, submit law enforcement plans to public safety, and prove financial responsibility. The bill defines the automated driving system as the legal "driver" for traffic law compliance and mandates vehicle registration/titling as "fully autonomous." This directly affects manufacturers and operators of autonomous ride-hailing services, commercial fleets, and transportation networks using self-driving technology.
