US grants self-driving truck makers five-year warning device exemption
The Federal Motor Carrier Safety Administration has granted Aurora Innovation, Kodiak AI and other self-driving truck developers a five-year exemption from a rule requiring drivers to place reflective warning triangles after a breakdown. The change clears a practical obstacle to commercialising autonomous trucks, which have no driver available to set out the devices, and allows them to use cab-mounted warning beacons instead.
The rule requires a human driver to pull over, switch on hazard lights and place warning triangles within 10 minutes. Aurora had challenged the requirement in court after its initial exemption request was denied, while the companies held a temporary waiver pending a decision. The article also reports that Redwood Materials has lost four vice-presidents amid a restructuring focused more heavily on energy storage, following layoffs of about 135 employees, or 10% of its workforce.
- US regulators approved a five-year warning beacon exemption.
- Aurora and Kodiak can use cab-mounted beacons on autonomous trucks.
- Redwood Materials has lost four vice-presidents amid restructuring.

Self-driving trucks are commercial vehicles designed to operate without human drivers. Several companies, including Aurora Innovation and Kodiak AI, are developing this technology, which could reshape the trucking industry.
Current transport safety rules require truck drivers to place reflective warning triangles within ten minutes of breaking down to alert other motorists. Autonomous trucks cannot comply because they have no driver to set out the devices manually, creating a clash between existing safety regulations and new technology.
The conflict between current safety requirements and autonomous vehicle capabilities represents a broader challenge for the industry. Developers argue that without changes to regulations written for human drivers, autonomous trucks cannot be deployed commercially even when the technology is otherwise ready.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
The purpose of warning triangles is to alert other motorists to a disabled vehicle; a cab-mounted beacon accomplishes this by providing visible warning. Requiring a physical triangle when there is no driver to place it is impractical and misses the underlying safety goal. If autonomous vehicles demonstrate superior safety overall, insisting on procedures that don't apply to their operation is counterproductive. A temporary exemption allows real-world data collection to prove the beacons are effective.
The case against
Warning triangles provide passive, physics-based safety that functions independently of electrical systems or equipment malfunction. A cab-mounted beacon relies on power, activation mechanisms, and proper functioning—introducing dependencies that a static, reflective device avoids. The exemption implements an untested solution without first establishing equivalence to the existing standard. Weakening safety rules without robust prior evidence may set a concerning precedent for future regulatory compromises.
