Uber is pursuing legal action in London after the government imposed new laws on ride-hailing services, hoping it can use legal channels to make it easier for the company to operate in England.

London has been working for the last year on methods to restrict ride-hailing services like Uber after taxi drivers in the city staged protests. The city imposed compulsory language tests on drivers, one of the main points Uber hopes to fight.

The new rules require all Uber drivers pass tests proving their English reading and writing skills. Uber says it’s fine with the requirement its drivers should speak English, but feels the testing is too rigorous.

London lawmakers also imposed a rule that ride-hailing companies must open London call centers by Oct. 1, and any drivers must have insurance for vehicles even when they’re not being used as rides.

Analysts say the regulations are bad for drivers and the companies that employ them, and that London is creating an atmosphere that will make it hard for start-ups to get a hold in the market. But London isn’t budging, promising to defend the laws in court.

“These have been introduced to enhance public safety when using private hire services and we are determined to create a vibrant taxi and private hire market with space for all providers to flourish,” a transport authority spokesperson told Reuters.
