From the Summon / InstantCab blog:

Today, Summon has become the first Transportation Network Company (TNC) to receive apermit from the California Public Utilities Commission (CPUC) allowing it to operate in California.

On-demand transportation apps form a new, exciting, and growing industry. California was the first state in the nation to pave the way for legalization of these types of apps, and Summon was the first company to meet each of California’s requirements and obtain an operating permit. Last September, the CPUC issued a decision requiring TNCs to obtain insurance to protect riders and members of the public in the event of an incident, conduct stringent background checks on drivers, have driver vehicles inspected, and complete several other safety-related steps to operate in California.
