NHTSA Proposes Cyan Lights for Driverless Vehicles Like Cybercab
NHTSA has filed a proposal to modernize the federal lighting standard FMVSS 108 for vehicles without a steering wheel or pedals, such as Tesla's Cybercab. The main change is optional cyan 'ADS marker lamps' that would indicate a vehicle is driving itself. Vehicles could use one or two per side, mounted at least 15 inches off the ground, and the lamps would stay steadily lit rather than flash. They would turn on when the vehicle drives without anyone expected to watch the road, and turn off when an occupant is expected to monitor it.…
- NHTSA proposes optional, steady cyan lights, only for driving without human supervision.
- The proposal will be published October 26, with a 30-day comment period.
- Tesla has over 300 Cybercabs in Austin, with Dallas rides expected next month.
🔎 Why it matters: The proposal amends FMVSS 108 for vehicles without a steering wheel or pedals, such as the Cybercab, and allows optional cyan ADS lamps. Its scope is limited to true driverless operation, not FSD (Supervised).
📈 Upside: It would create a common visual signal to identify when a vehicle is driving itself, and let the self-driving system handle turn signals, hazards, and headlights without physical buttons.
📉 Risk: NHTSA still has an open investigation into how the Cybercab was certified for commercial deployment, and the rule is not yet finalized.
