Alphabet Inc.’s Waymo unit on Tuesday became the first company to receive a permit from the state of California to test driverless vehicles without a backup driver in the front seat, the state’s Department of Motor Vehicles said.

California said Waymo can use about three dozen test vehicles without drivers behind the wheel in Santa Clara County. About 60 companies have permits in the state to test self-driving cars with a backup driver, including most major automakers and Apple Inc. As part of winning approval, Waymo must continuously monitor the status of test vehicles, provide two-way communication with passengers, carry at least $5 million in insurance and notify local communities.

Waymo’s permit includes day and night testing on city streets, rural roads and highways with posted speed limits of up to 65 miles per hour. The company said its vehicles can safely handle fog and light rain, and testing in those conditions is allowed.

“California has been working toward this milestone for several years, and we will continue to keep the public’s safety in mind as this technology evolves,” said Jean Shiomoto, director of California’s Department of Motor Vehicles, in a statement.

The company said it will begin driverless testing on city streets in Silicon Valley and expand to other areas after it notifies local communities. The company will begin tests with Waymo employees and eventually “create opportunities for members of the public to experience this technology, as we’ve done in Arizona with our early rider program.”

In Arizona, Waymo has been conducting some testing of vehicles without backup drivers and has said it plans to launch a commercial self-driving ride hailing service in the state by the end of 2018.
