What’s in it

Under current law, a driverless-capable vehicle equipped with an automated driving system and meeting certain requirements is authorized to operate on highways while performing all real-time operational and tactical functions (dynamic driving task) regardless of whether a conventional human driver is present in the vehicle.519 and all applicable traffic and motor vehicle safety laws. This bill prohibits a driverless-capable vehicle transporting hazardous material from operating without a conventional human driver.

secretary of transportation to be capable of posing an unreasonable risk to health, safety, and property when transported in commerce, and which has been so designated.482. _____ than $855. Under current law, an automated driving system that is capable of performing the entire dynamic driving task must be designed to operate within the system’s operational design domain in compliance with the applicable traffic and motor vehicle safety laws and regulations that govern the performance of the dynamic driving task, unless an exemption has been granted to the vehicle by the department of transportation. The bill rephrases this provision to require the system to operate within the system’s operational design domain rather than be designed to operate in that manner. The bill imputes liability to the owner of a driverless-capable vehicle for personal injury, death, or property damage that results in connection with the operation of the vehicle and for violations of traffic or motor vehicle safety laws and regulations. A person who modifies an automated driving system of a driverless-capable vehicle without the manufacturer’s consent is liable for any damage related to the operation of the vehicle, unless the owner of the vehicle directed the person to modify the system, in which case the owner is liable.
