(7) "Driverless operation" means the operation of an ADS-equipped vehicle in which:   (a) no on-board user is present; or     (b) no on-board user is a human driver or fallback-ready user.       (8) "Driverless operation dispatcher" means a user who dispatches an ADS-equipped vehicle in driverless operation.     (9) "Driving automation system" means the hardware and software collectively capable of performing part or all of the dynamic driving task on a sustained basis.     (10) "Driving automation system feature" means a specific function of a driving automation system.     (11)   (a) "Dynamic driving task" means all of the real-time operational and tactical functions required to operate a motor vehicle in on-road traffic, including:   (i) lateral vehicle motion control through steering;     (ii) longitudinal motion control through acceleration and deceleration;     (iii) monitoring the driving environment through object and event detection, recognition, classification, and response preparation;     (iv) object and event response execution;     (v) maneuver planning; and     (vi) enhancing conspicuity with lighting, signaling, and gesturing.       (b) "Dynamic driving task" does not include strategic functions such as trip scheduling and selection of destinations and waypoints.       (12) "Engage" as it pertains to the operation of a vehicle by a driving automation system means to cause a driving automation system feature to perform part or all of the dynamic driving task on a sustained basis.     (13) "External event" is a situation in the driving environment that necessitates a response by a human driver or driving automation system.     (14) "Fallback-ready user" means the user of a vehicle equipped with an engaged level three ADS who is:   (a) a human driver; and     (b) ready to operate the vehicle if:   (i) a system failure occurs; or     (ii) the ADS issues a request to intervene.         (15)   (a) "Human driver" means a natural person:   (i) with a valid license to operate a motor vehicle of the proper class for the motor vehicle being operated; and     (ii) who performs in real-time all or part of the dynamic driving task.       (b) "Human driver" includes a:   (i) conventional driver; and     (ii) remote driver.         (16) "Level five automated driving system" or "level five ADS" means an ADS feature that has the capability to perform on a sustained basis the entire dynamic driving task under all conditions that can reasonably be managed by a human driver, as well as any maneuvers necessary to respond to a system failure, without any expectation that a human user will respond to a request to intervene.     (17) "Level four automated driving system" or "level four ADS" means an ADS feature that, without any expectation that a human user will respond to a request to intervene, has:   (a) the capability to perform on a sustained basis the entire dynamic driving task within its operational design domain; and     (b) the capability to perform any maneuvers necessary to achieve a minimal risk condition in response to:   (i) an exit from the operational design domain of the ADS; or     (ii) a system failure.         (18) "Level three automated driving system" or "level three ADS" means an ADS feature that:   (a) has the capability to perform on a sustained basis the entire dynamic driving task within its operational design domain; and     (b) requires a fallback-ready user to operate the vehicle after receiving a request to intervene or in response to a system failure.       (19) "Minimal risk condition" means a condition to which a user or an ADS may bring a motor vehicle in order to reduce the risk of a crash when a given trip cannot or should not be completed.     (20) "Object and event detection and response" means the subtasks of the dynamic driving task that include:   (a) monitoring the driving environment; and     (b) executing an appropriate response in order to perform the dynamic driving task.       (21) "On-demand autonomous vehicle network" means a transportation service network that uses a software application or other digital means to dispatch or otherwise enable the prearrangement of transportation with motor vehicles that have a level four or five ADS in driverless operation for purposes of transporting persons, including for-hire transportation and transportation for compensation.     (22) "Operate" means the same as that term is defined in Section 41-1a-102.     (23) "Operational design domain" means the operating conditions under which a given ADS or feature thereof is specifically designed to function, including:   (a) speed range, environmental, geographical, and time-of-day restrictions; or     (b) the requisite presence or absence of certain traffic or roadway characteristics.       (24) "Operator" means the same as that term is defined in Section 41-6a-102.     (25) "Passenger" means a user on board a vehicle who has no role in the operation of that vehicle.     (26) "Person" means the same as that term is defined in Section 41-6a-102.     (27) "Remote driver" means a human driver who is not located in a position to manually exercise in-vehicle braking, accelerating, steering, or transmission gear selection input devices, but operates the vehicle.     (28) "Request to intervene" means the notification by an ADS to a fallback-ready user indicating that the fallback-ready user should promptly begin or resume operation of the vehicle.     (29) "Sustained operation of a motor vehicle" means the performance of part or all of the dynamic driving task both between and across external events, including response to external events and continued performance of part or all of the dynamic driving task in the absence of external events.     (30) "System failure" means a malfunction in a driving automation system or other vehicle system that prevents the ADS from reliably performing the portion of the dynamic driving task on a sustained basis, including the complete dynamic driving task, that the ADS would otherwise perform.     (31) "User" means a:   (a) human driver;     (b) passenger;     (c) fallback-ready user; or     (d) driverless operation dispatcher.      Enacted by Chapter 459, 2019 General Session
