Newark officials on Friday backed away from a pledge to begin towing vehicles belonging to Uber drivers at the city’s airport and train station, a setback in the city’s yearlong effort to crack down on the ride-sharing service.

The reversal by Newark officials marked another victory for Uber, which won a bruising battle with New York City Mayor Bill de Blasio last year over a proposed cap on new vehicles. The company argued such a limit threatened its growth and the popular service’s reliability.

In Newark, the towing was scheduled to start Monday, according to a letter Uber received in late January from Newark Chief Prosecutor Evans Anyanwu, who accused the company of violating the city’s taxicab laws.

On Friday afternoon, a spokesman for Newark’s mayor confirmed that the city is no longer planning to tow cars.

“Our Public Safety Department is still reviewing the Uber situation and determining what action to take, if any,” the spokesman said.
