What it means

The U.S. National Highway Traffic Safety Administration () has proposed a new regulation that would require autonomous vehicles (self-driving cars) to be equipped with cyan-colored lights that activate when the vehicle is driving itself. This visual signal is intended to inform pedestrians, cyclists, and other drivers that the vehicle is in autonomous mode, compensating for the absence of a human driver who might otherwise make eye contact or hand gestures. The proposal moves toward a standardized method for autonomous vehicles to communicate their operating status, aligning with related efforts by SAE International and the United Nations.

Accuracy & sourcesGrounded

The claim is based on a direct report from The Verge covering a formal NHTSA rulemaking proposal. As a reputable secondary source citing a primary government document, the reporting carries high credibility for the existence and nature of the proposal. Earlier industry discussions and UNECE regulations on cyan/turquoise marker lamps for autonomous vehicles support the plausibility of the NHTSA action.
