Implications of Automation for Motor Vehicle Codes

Existing motor vehicle codes have been developed based on implicit assumptions about drivers maintaining continuous involvement in the driving task and continuous responsibility for managing traffic safety hazards. Automated driving systems significantly reduce the role of the driver, which means that some of these codes will need to be reconsidered. The incorporation of driving behavior into in-vehicle software also generates pressure to harmonize the rules of the road across jurisdictions. The objective of this research was to provide state departments of transportation (DOTs) and motor vehicle departments with guidance and resources to assist with the legal changes that will result from the roll out of connected and automated vehicles. This research does the following: (1) Provides a review applicable existing laws and regulations that may need reconsideration as connected vehicles (CV) and connected and automated vehicles (AV) become more widely used with a focus on how these codes need to be revised (and how soon). (2) Expected changes to motor vehicle laws, regulations, and statutes related to CV and AV may affect current driving practices and continuous responsibility for managing traffic safety hazards. (3) Identifies barriers to implementation of new Rules of the Road resulting from the roll out of CV and AV and develop strategies to overcome them. (4) Addresses processes and stages for modifying relevant motor vehicle code, laws, regulations, and statutes.
