The Kansas law requires transportation network companies, which is the legislature’s term for ridesharing, to adhere to certain rules including criminal background checks for drivers and carrying $1 million in insurance when a fare is in a vehicle. The state’s governor, Sam Brownback, actually vetoed the bill, but both the Senate and House there overrode his decision.

Uber issued a lengthy statement on its blog asserting that the legislation harmed citizen’s safety because people won’t be able to hail rides when drunk. The law also created “unbalanced, backward regulations” and was putting drivers out of work, according to Uber. Kansas is the only state so far to force the app out, and according to CNN Money, the insurance requirement is the sticking point between the company and the government.
