Automated Vehicles State Legislation
• Many states are writing legislation allowing testing of automated CMVs
• Risk management for testing of advanced CMVs with ADAS should be considered by developers and the States

Federal Automated Policy
Version 2.0[Released September12, 2017]
• Voluntary Guidance for the operations of ADAS
• Intended to support stakeholders as they consider and design practices relative to the testing and deployment of AV technologies
• Listed FMCSA requirement for driver-monitored operations unless a waiver or exemption is granted
Version 3.0[Scheduled for release in 2018]
• Broader; DOT-wide
• Focus on the safe integration of road vehicles into the transportation system
• Topics may change if Congress passes its AV legislation
