New color on the road. Turquoise lights are meant to inform who is driving

The NHTSA is proposing changes to the FMVSS 108 vehicle lighting standard to accommodate automated driving systems, including vehicles without steering wheels or pedals. One key feature is the introduction of turquoise signal lights that would indicate when a vehicle is being driven by its system rather than a human. These lights would remain on during automated driving and turn off when human oversight is needed. Manufacturers would have the option to install this lighting, which must follow specific visibility and placement guidelines. The proposal is currently open for public comment for 30 days. Mercedes-Benz has already tested these lights in California and Nevada, with approvals for certain models starting in 2026, indicating that the presence of turquoise lights does not mean there is no driver present.
