Update: The New York City Council has voted to cap Uber vehicles.

As Uber has grown into a global behemoth, upending urban transportation networks and changing the way people get around, the company has often found itself clashing with local governments or trying to dig itself out of a public relations morass.

On Wednesday, it is likely to suffer one of its biggest blows.

The New York City Council is expected to vote on a cap for Uber vehicles — a move that would be a major setback for the tech giant in its largest American market.

The City Council plans to vote on a package of bills that would halt the issuance of new licenses for Uber and other ride-hail vehicles for a year while the city studies the booming industry. The legislation would also allow the city to set a minimum pay rate for drivers.

Why does the city say a cap is needed?

Mayor Bill de Blasio and Corey Johnson, the City Council speaker, say the bills will address worsening street congestion and improve low driver wages.
