According to the City of New York the answer is no. As of August 19th, New York City Yellow-Taxi drivers no longer have to take a language proficiency exam before they can drive. According to the man who sponsored the bill, Ydanis Rodriguez, a former livery driver himself, says this bill will help taxi drivers compete with other ride companies such as Uber and Lyft, both of whom lack an English Language exam. There has been a mix of reactions with many people worrying that the drivers will be unable to understand the location that the customer wishes to go. While others are fine with the change and are appearing unconcerned with a potential loss of communication with their taxi driver.
