Zoox Halts Atlanta Self-Driving Tests After Staff Report Toxic Gas Exposure

Zoox, the autonomous‑vehicle arm owned by Amazon, has stopped its Atlanta test fleet after workers reported symptoms that match exposure to a poisonous gas.

The firm said it launched an internal probe after a worker lodged a complaint with the Occupational Safety and Health Administration. That filing led Zoox to pause all on‑road trials in Georgia while it evaluates the matter.

The complaint notes that the employees experienced headaches, nausea and respiratory irritation while operating in a garage that services the fleet. Zooth’s statement said the suspected exposure took place in a confined charging and maintenance zone, though it did not identify the specific chemical.

Acquired by Amazon in 2020, Zoox has been rolling out its autonomous‑driving initiative in multiple U.S. cities. The Atlanta location formed part of a larger expansion that also includes pilots in California and Nevada. The testing suspension arrives as the sector faces intensified scrutiny over safety measures and worker protection.

Regulators generally expect employers to address hazards swiftly, and OSHA inquiries can result in citations or required corrective steps. Zoox has not verified whether OSHA has opened a formal case, but it has pledged to cooperate with any investigation and reaffirmed its dedication to employee health and safety.

Industry analysts warn the episode could push back Zoox’s schedule for launching its robotaxi service in the Southeast. The company has previously promoted its “zero‑emissions” electric platform, and any hint of environmental or safety shortcomings could sway public and investor sentiment. Zoox gave no timeline for resuming tests, saying the decision will hinge on the internal review’s findings and any regulatory direction.
