Requires driving automation systems to operate only within a clearly defined operational design domain (ODD). It would make manufacturers declare that ODD to the National Highway Traffic Safety Administration and publish the exact declaration on a public website.
Show full summary
- Manufacturers: Must ensure their driving automation systems do not operate outside the ODD and must submit a declaration of that ODD to NHTSA. They must publish the exact declaration online so buyers can see where a system is intended to work.
- Drivers and the public: Would provide clearer limits on where automated driving is allowed and public access to the system's operating conditions, including geography, time of day, and road or traffic characteristics.
- Regulators and enforcement: Creates a formal place in law for NHTSA to receive ODD declarations and enables civil penalties for violations tied to the new safe-domain rule.
- Legal definitions and timing: Modifies the federal definition of “motor vehicle safety standard” to include these safe-domain requirements and becomes effective 180 days after enactment.

New safety rules for automated driving
This bill would require manufacturers of automated driving systems to define an operational design domain (ODD). The ODD must list environmental, geographic, time-of-day, and traffic or roadway conditions where the system is meant to work. Manufacturers would have to keep systems from operating outside that ODD, submit the exact ODD declaration to the NHTSA Administrator, and publish the same declaration on a public website. If enacted, NHTSA would be able to treat those ODD requirements as motor vehicle safety standards and use civil penalties for violations. These requirements would take effect 180 days after enactment.
