L. "Levels of driving automation" means the functionality of an automated driving system and allocation of roles between a human user (if any) and the driving automation system in performing the dynamic driving task and fallback. Levels of driving automation is categorized into six levels by the SAE in Standard J3016, Taxonomy and Definitions for Terms Related to Driving Automation Systems for On-Road Motor Vehicles. The six levels include:

(1) Level 0 means 'no driving automation' in that the performance by the driver of the entire dynamic driving task even when enhanced by active safety systems.

(2) Level 1 means 'driver assistance' in that the sustained and operational design domain-specific execution by a driving automation system of either the lateral or the longitudinal vehicle motion control subtask of the dynamic driving task (but not both simultaneously) with the expectation that the driver performs remainder of the dynamic driving task.

(3) Level 2 means 'partial driving automation' in that the sustained and operational design domain-specific execution by a driving automation system of both the lateral and longitudinal vehicle motion control subtasks of the dynamic driving task with the expectation that the driver completes the object event detection and response subtask and supervises the driving automation system.

(4) Level 3 means 'conditional driving automation' in that the sustained and operational design domain-specific performance by an automated driving system of the entire dynamic driving task with the expectation that the dynamic driving task fallback-ready user is receptive to automated driving system-issued requests to intervene, as well as to dynamic driving task performance-relevant system failures in other vehicle systems and will respond appropriately.

(5) Level 4 means 'high driving automation' in that the sustained and operational design domain-specific performance by an automated driving system of the entire dynamic driving task and dynamic driving task fallback without any expectation that a user will respond to a request to intervene.
