SAN FRANCISCO — One of the founders of Otto, a self-driving truck company founded by former Google employees and acquired by Uber, has left the ride-hailing service.

Lior Ron — who along with Anthony Levandowski sold Otto to Uber in 2016, six months after leaving Google — was in charge of Uber Freight, a truck shipment booking service. Most of Uber Freight’s business does not involve the company’s autonomous trucks.

The departure followed a fatal crash involving an Uber self-driving car in Tempe, Ariz. The police said the car, driving in autonomous mode, had failed to slow down before it struck and killed a woman who was walking her bicycle across a street.

Uber has stopped testing of its autonomous vehicles in Arizona, California, Pittsburgh and Toronto while investigators look into the accident. A week after Uber halted testing, Arizona’s governor ordered the company’s self-driving cars off state roads. Uber also pulled an application to renew its permit for testing autonomous vehicles in California.
