1. Short title This Act may be cited as the Designating Each Car’s Automation Level Act or the DECAL Act . 2. Information on highly automated driving systems made available to prospective buyers (a) Research Not later than 3 years after the date of enactment of this Act, the Secretary of Transportation shall complete research to determine the most effective method and terminology for informing consumers for each highly automated vehicle or a vehicle that performs partial driving automation about the capabilities and limitations of that vehicle. The Secretary shall determine whether such information is based upon or includes the terminology as defined by SAE International in Recommended Practice Report J3016 (published September 2016) or whether such description should include alternative terminology. (b) Rulemaking After the completion of the study required under subsection (a), the Secretary shall initiate a rulemaking proceeding to require manufacturers to inform consumers of the capabilities and limitations of a vehicle’s driving automation system or feature for any highly automated vehicle or any vehicle that performs partial driving automation. (c) Definitions (1) In general In this section— (A) the term automated driving system means the hardware and software that are collectively capable of performing the entire dynamic driving task on a sustained basis, regardless of whether such system is limited to a specific operational design domain; (B) the term dynamic driving task means all of the real time operational and tactical functions required to operate a vehicle in on-road traffic, excluding the strategic functions such as trip scheduling and selection of destinations and waypoints, and including— (i) lateral vehicle motion control via steering; (ii) longitudinal vehicle motion control via acceleration and deceleration; (iii) monitoring the driving environment via object and event detection, recognition, classification, and response preparation; (iv) object and event response execution
