These taxi drivers were really flying.

The city Taxi and Limousine Commission yanked 43 hack licenses from cabbies who flunked a mandatory annual drug test last year, The Post has learned.

The behind-the-wheel substance abusers tested positive for drugs such as marijuana, cocaine and amphetamines, TLC records show.

Pot showed up in 14 yellow-cab drivers’ results, while two screenings showed cocaine use.

Of “for-hire” livery-car drivers who were also tested, 17 were nailed for marijuana, nine for cocaine and one for amphetamines.
