Uber has launched legal action against new rules in London such as written English tests for its drivers, in the latest battle between regulators and the car ride app which has faced bans and protests worldwide.

Following months of demonstrations from drivers of the capital’s famous black cabs, public body Transport for London (TfL) launched a consultation last year on a raft of proposals to restrict the way private hire firms operate.

In January, it decided against imposing a five-minute wait time for rides on customers of services such as Uber, which allows customers to book and pay for a taxi on their smartphones, but said that it would bring in measures including compulsory language tests.

In recent months, the regulator has provided more detail including that drivers should have English reading and writing skills, that private hire firms must operate a London call centre and drivers must have insurance for vehicles even when they are not being used as private hire cars.

“The goalposts have moved at the last minute and new rules are now being introduced that will be bad for both drivers and tech companies like Uber,” its London general manager Tom Elvidge said.

Rapidly expanding tech start-ups are having to navigate regulations and opposition from some unions and existing service providers around the world. Uber said it backed drivers being able to speak English but the proposed tests were too rigorous.
