A bill for an act relating to the operation of driverless-capable vehicles, including associated civil and criminal liability, and making penalties applicable.

HSB 598 allows driverless-capable vehicles to operate on Iowa public roads without a human driver present, provided they meet safety conditions like achieving a "minimal risk condition" during malfunctions, complying with traffic laws, and being certified by the manufacturer. It specifically prohibits driverless operation for vehicles transporting hazardous materials, requiring a human driver in those cases. The bill establishes that the vehicle owner is liable for injuries, property damage, or traffic violations occurring when the automated system is engaged. Modifications to the automated driving system without the manufacturer's consent also create liability, unless the owner directed the change.
