Plain-language change summary

The revised version of Bill HB 581 shifts the focus from establishing a pilot program for autonomous transportation aimed at the upcoming Olympic Games to directing a large public transit district and the Department of Transportation to gather information on autonomous vehicles. This change simplifies the approach by removing specific grant opportunities for vehicle deployment and instead emphasizes a broader study of autonomous vehicle technology. This matters because it could affect how quickly and effectively cities can integrate autonomous vehicles into their public transit systems, ultimately influencing transportation options for residents.

Operation of motor vehicles equipped with an automated driving system.
(1) A motor vehicle equipped with a level two or level three ADS may operate on a highway in this state if:
(a) the motor vehicle is operated, whether by the ADS or human driver with a valid driver license, in compliance with the applicable traffic and motor vehicle safety laws and regulations of this state, unless an exemption has been granted;
[(b) when required by federal law, the motor vehicle:] [(i) has been certified as being in compliance with all applicable motor vehicle safety standards;
and] [(ii) bears the required certification label, including reference to any exemption granted under federal law;] - 30 - HB0581 compared with HB0581S02 [(c)] (b) when operated by an ADS, if a system failure occurs that renders the ADS unable to perform the entire dynamic driving task relevant to the intended operational design domain of the ADS, the ADS will achieve a minimal risk condition or make a request to intervene;
and [(d)] (c) the motor vehicle is titled and registered in compliance with Section 41-26-107.
(2) A motor vehicle equipped with a level four or level five ADS may operate in driverless operation on a highway in this state if:
(a) the ADS is capable of operating in compliance with applicable traffic and motor vehicle laws and regulations of this state, unless an exemption has been granted;
[(b) when required by federal law, the motor vehicle:] [(i) has been certified as being in compliance with all applicable Federal Motor Vehicle Safety Standards and regulations;
and] [(ii) bears the required certification label including reference to any exemption granted under federal law;] [(c)] (b) a system failure occurs that renders the ADS unable to perform the entire dynamic driving task relevant to the intended operational design domain of the ADS, a minimal risk condition will be achieved;
and [(d)] (c) the motor vehicle is titled and registered in compliance with Section 41-26-107 and Section 41-1a-202.
(3) A vehicle being operated by [an] a level four or level five ADS or a remote driver is not considered unattended.
(4) For a vehicle equipped with a level two or level three ADS:
(a) a human driver remains the operator for purposes of:
(i) monitoring the roadway and traffic conditions;
(ii) responding to system alerts and takeover requests;
(iii) maintaining compliance with traffic laws;
and (iv) civil and criminal liability if the human driver:
(A) fails to maintain required attention;
(B) fails to respond to system warnings;
or (C) engages the system improperly;
and (b) an ADS manufacturer remains liable for:
(i) system malfunctions that cause or contribute to violations or crashes;
