Feds want robotaxis to signal ‘I’m driving’ with cyan-colored lights
Friday, October 23, 2026
The National Highway Traffic Safety Administration proposed changes to Federal Motor Vehicle Safety Standard No. 108 that would require autonomous vehicles to use cyan-colored lights to signal that no human driver is operating the vehicle. The proposal addresses years of industry discussion about how driverless cars should communicate their operational status to other road users. NHTSA has not yet finalized the standard or set an effective date.
