Waymo’s latest safety data suggests its autonomous vehicles are significantly reducing injury-causing crashes in Metro Phoenix, where the company has accumulated more than 92 million rider-only miles.
According to new data released by Waymo, its autonomous driving system recorded a 71% reduction in crashes involving reported injuries in Phoenix compared with human drivers — representing 128 fewer injury-causing crashes. The Waymo Driver also recorded 90% fewer crashes involving serious injuries or worse and a 77% reduction in crashes involving airbag deployment.

The Phoenix results are part of a broader analysis examining more than 271 million fully autonomous miles driven through June 2026 across Phoenix, Atlanta, Austin, Los Angeles and San Francisco, including the Bay Area.
Across those markets, Waymo reported an 82% reduction in injury-causing crashes compared with human drivers and a 95% reduction in crashes resulting in serious injuries or worse.
Based on its analysis, Waymo estimates its autonomous vehicles were involved in 841 fewer injury-causing crashes than would have been expected if human drivers had traveled the same number of miles. About 55 of those crashes would have been expected to result in serious injuries or worse.
The company’s data also points to significant safety improvements for some of the road’s most vulnerable users. Across the five markets, Waymo reported 93% fewer injury-causing crashes involving pedestrians, 86% fewer involving cyclists and 82% fewer involving motorcyclists. Waymo estimates more than 175 of the injury crashes avoided would have involved pedestrians, cyclists or motorcycle riders.
For Arizona, the findings are particularly notable because Phoenix represents one of Waymo’s largest and most established autonomous vehicle markets.
Waymo also released footage illustrating situations in Phoenix in which its autonomous driving technology potentially prevented collisions. One involved a cyclist, while another showed a potential head-on collision.
