The San Francisco company's lobbyists are pushing lawmakers to exempt its drivers from obtaining commercial licenses before they can ferry passengers. Uber Technologies Inc. and its biggest competitor, Lyft Inc., depend on drivers with personal licenses who use their own cars to pick up fares hailed through a smartphone app.

Uber has spent almost a million dollars since 2013 on lobbyists in California. Responsible for a million daily rides worldwide, the company is fighting from the Pacific to the Atlantic to derail efforts by regulators, lawmakers and the taxi industry to extend rules governing cabs to the nascent ride-sharing industry.

"They hired a whole fleet of lobbyists," said Senator Jim Beall, a Democrat and chairman of the Transportation and Housing Committee who opposes the measure the company wants passed. "They're all over the place. You see them prowling around the capitol building."

New York Mayor Bill de Blasio last month dropped a proposal to cap Uber fleets after backlash from the company, its allies and Governor Andrew Cuomo, a fellow Democrat. In Nevada, company lobbyists in May persuaded lawmakers to let its drivers operate, including in the coveted Las Vegas market.

In the U.S., 54 cities and states have regulated and legitimized ride-sharing, Uber spokeswoman Eva Behrend said in an e-mailed statement. California is Uber's first and biggest U.S. market. It began operating in San Francisco in 2010 and offered its widely used uberX ridesharing service in 2013, billed as "like a taxi -- only quicker, cleaner and a little bit magical."
