An accident involving a Waymo robotaxi hitting a child near a Santa Monica school has prompted one of California’s largest unions to call for the Alphabet-owned driverless cab service to shut down statewide.

Teamsters California on Monday urged the California Public Utilities Commission (CPUC) to indefinitely suspend Waymo’s license to operate in the state, arguing that the incident highlights broader safety and labor concerns tied to autonomous vehicles.

“This incident is emblematic of the broader goal Big Tech companies need to replace skilled human labor with AI,” Teamsters Co-Chairs Peter Finn and Victor Mineros said in a statement. “They want to force millions of people into poverty by destroying their livelihoods, taking money that belongs to workers, and forcing our communities to reckon with the fallout from automation.

The union’s statement comes just days after the National Highway Traffic Safety Administration (NHTSA) announced it. opened a probe in the event.

The accident occurred on January 23 during school dismissal hours, when a child reportedly ran to school from behind a parked SUV and was hit by a Waymo robotaxi. According to Waymo, the car’s system detected the child immediately after they started running, prompting the car to brake hard and reduce its speed from nearly 17 miles per hour to less than 6 miles per hour before contact was made.

Waymo said that the boy stood up immediately after the collision and was able to walk on the sidewalk. The vehicle then called 911 and remained at the scene until law enforcement gave it the all clear to leave.

In announcing its investigation, NHTSA’s Office of Defects Investigation said it would examine whether Waymo “exercised reasonable precautions given, among other things, its proximity to an elementary school during drop off times, and the presence of young pedestrians and other potentially vulnerable road users.” The probe will also examine the desired behavior of the robotaxi automated driving system in school zones.

This is not the only NHTSA investigation involving Waymo and schools. Last month, NHTSA sent Waymo a letter announcing a separate investigation following reports that Waymo vehicles failed to stop for school buses with their lights on, instead driving around them.

Waymo did not immediately respond to a request for comment from Gizmodo. In a blog post about the accident, however, the company said, “We remain committed to improving road safety where we operate as we continue our mission to be the world’s most reliable driver.”

Teamsters California represents nearly 250,000 workers across industries, including construction, warehousing, trucking, and transportation. The union points to the ongoing school-bus investigation as evidence that regulators need to act more aggressively.

“Waymo vehicles continue to illegally ignore school bus stop signs despite a company-wide software recall and another, separate NHTSA investigation,” the Teamsters statement said. “Parents, teachers, school workers, and community members have asked that these vehicles be kept off school premises. Waymo and its parent company, Google, have chosen to ignore those warnings.”

The CPUC did not immediately respond to a request for comment from Gizmodo.

California isn’t the only place where robotaxi services have drawn opposition from workers. Last year, a coalition of unionsincluding Teamsters Local 25, backed a proposed ordinance that would commission a study of the impact autonomous vehicles could have on the city and use the assessments to develop rules for autonomous vehicle operators. The union is also backing legislation that would require robotaxis to accompany it human operators.
