§ 186.760

186.760 Definitions for KRS 186.760 to 186.779. As used in KRS 186.760 to 186.779: (1) 'Automated driving system' means hardware and software that are collectively capable of performing the entire dynamic driving task on a sustained basis, regardless of whether it is limited to a specific operational design domain; (2) 'Dynamic driving task' or 'DDT': (a) Means all of the real -time operational and tactical functions required to operate a vehicle in on -road traffic, including without limitation: 1. Lateral vehicle motion control via steering; 2. Longitudinal motion control via acceleration and deceleration; 3. Monitoring the driving environment via object and event detection, recognition, classification, and response preparation; 4. Object and event response execution; 5. Maneuver planning; and 6. Enhancing conspicuity via lighting, signaling, and gesturing; and (b) Does not include strategic functions such as trip scheduling and the selection of destinations and waypoints; (3) 'DDT fallback' means the response by: (a) The person or human driver to either perform the DDT or achieve a minimal risk condition after occurrence of a DDT performance relevant system failure, or upon

DT fallback' means the response by: (a) The person or human driver to either perform the DDT or achieve a minimal risk condition after occurrence of a DDT performance relevant system failure, or upon operational design domain exit; or (b) An automated driving system to achieve minimal risk condition, given the same circumsta nces identified in paragraph (a) of this subsection; (4) 'Fully autonomous vehicle' means a motor vehicle equipped with an automated driving system designed to function without a human driver as a level 4 or 5 system under SAE J3016; (5) 'Human driver' mea ns a natural person in the vehicle with a valid license to operate a motor vehicle who controls all or part of the dynamic driving task; (6) 'Minimal risk condition' means a condition to which a person, human driver, or an automated driving system may brin g a vehicle after performing the DDT fallback in order to reduce the risk of a crash when a given trip cannot or should not be completed; (7) 'Operational design domain' or 'ODD' means the operating conditions under which a given automated driving system i s specifically designed to function, including but not limited to: (a) Environmental, geographical,

sign domain' or 'ODD' means the operating conditions under which a given automated driving system i s specifically designed to function, including but not limited to: (a) Environmental, geographical, and time -of-day restrictions; and (b) The requisite presence or absence of certain traffic and roadway characteristics; (8) 'Public agency' has the same mea ning as in KRS 61.870; (9) 'Request to intervene' means a notification by an automated driving system to a human driver that the human driver should promptly begin or resume performance of part or all of the dynamic driving task; and (10) 'SAE J3016' means the 'Taxonomy and Definitions for Terms Related to Driving Automation Systems for On -Road Motor Vehicles' published by SAE International on June 15, 2018, as amended. Effective: July 15, 2024 History: Created 2024 Ky. Acts ch. 176, sec. 1, effective July 15, 2024.
