The Washington State Transportation Commission (WTSC)’s Autonomous Vehicle Work Group has for several years looked at how to effectively regulate driverless cars operating on public roads in a way that ensures public safety while not impeding testing and deployment. Now, SB 5460 sponsored by Sen. Joe Nguyen (D-34) would create a legal definition for driverless cars operating in the state, though some stakeholders testifying at a Feb. 18 public hearing in the Senate Transportation Committee opposed provisions that would give the state Department of Licensing (DOL) additional rulemaking authority.
