Federal safety officials said on Thursday they are opening an investigation into an incident in which a Waymo autonomous vehicle struck a child near an elementary school in Santa Monica, California. The National Highway Traffic Safety Administration (NHTSA) described the event as occurring during normal school drop-off hours on Jan. 23 and resulting in only minor injuries to the child involved.
According to the agency's account, the child ran across the street from behind a double-parked SUV toward the school and was hit by the Alphabet-owned Waymo vehicle. NHTSA noted that other children were present in the area at the time, a crossing guard was on duty, and several vehicles were double parked in the vicinity.
The agency said it is initiating a preliminary evaluation to determine whether the Waymo autonomous vehicle exercised appropriate caution given its proximity to the elementary school and the presence of young pedestrians and other potentially vulnerable road users. NHTSA's stated inquiry will examine the vehicle's intended behavior in school zones and adjacent areas, especially during normal pick-up and drop-off periods.
Specifically, NHTSA plans to review, but not limit itself to, the vehicle's adherence to posted speed limits in school zones and nearby streets during those busy times. The agency also said it will investigate Waymo's post-impact response following the collision.
The incident occurred on Jan. 23 in Santa Monica. NHTSA's preliminary evaluation is the first formal step in its investigative process and is intended to collect information to determine whether a deeper or broader probe is warranted. The agency's review will focus on whether the autonomous system's programming and real-world behavior appropriately accounted for the heightened pedestrian activity typical of school drop-off windows.
No additional injuries besides the minor harm to the child were reported in the agency's statement. The probe centers on the vehicle's conduct in a setting with multiple potential hazards - including children, a crossing guard, and double-parked vehicles - which NHTSA highlighted in its description of the scene.
Context and implications
While the agency's announcement does not draw conclusions about causation or assign fault, it establishes that NHTSA will review both the vehicle's behavior leading up to the impact and its actions after the collision. The probe will consider how autonomous vehicle systems are intended to operate in environments where young pedestrians and other vulnerable users are likely to be present, and whether those systems adhere to traffic controls such as posted speed limits.
The investigation is ongoing and the agency's preliminary evaluation will determine what, if any, further steps are appropriate.
