'A congestion pricing surcharge for all for-hire vehicles traveling through some parts of Manhattan has begun. The surcharge kicked in February 2019, meaning Ubers, Lyfts and other car services driving south of 96th Street in Manhattan will see a $2.75 surcharge. That's on top of the base fares for each company. Yellow cabs will cost an extra $2.50, on top of the long-standing base fare of $5.50 just to get inside the vehicle. "Nowadays, the business is very slow," said M.D. Alam, a New York City taxi driver. "When this kind of thing happens, in the morning time people go to school, they walk blocks and blocks and don't take a cab. So it really affects our business." '
