Waymo and the California Department of Motor Vehicles announced Tuesday that the Golden State had approved a permit for the self-driving-car company to drive in a handful of Silicon Valley cities.

Those cities include Palo Alto, Los Altos, Los Altos Hills, Sunnyvale, and Alphabet's home city of Mountain View.

Waymo, which was formerly a division of Alphabet subsidiary Google, has been allowed under state law to operate autonomous cars since 2014. The new permit, the DMV says, "allows the company to test a fleet of about three dozen test vehicles without drivers behind the wheel."

While Waymo is the first such company to get this type of permit, the DMV also noted that 60 manufacturers have licenses that allow them to operate with "safety drivers."

According to the company, its permit allows "day and night testing on city streets, rural roads, and highways with posted speed limits of up to 65 miles per hour."

"If a Waymo vehicle comes across a situation it doesn't understand, it does what any good driver would do: comes to a safe stop until it does understand how to proceed," Waymo continued in a press release. "For our cars, that means following well-established protocols, which include contacting Waymo fleet and rider support for help in resolving the issue."
