A weekend sting operation by the New York State Department of Transportation and police put all 14 buses stopped at one Manhattan checkpoint off the road, according to a state official familiar with the investigation.
The official says the statewide operation directed by Gov. Andrew Cuomo comes a week after a horrific tour bus crash in the Bronx that killed 15 people.
The official spoke on the condition of anonymity because of the sensitivity of the sting operation involving police statewide that continued through Saturday.
At the stop, New York City police reported nine "major issues'' with drivers including lack of an updated log book required to see how long a driver has been behind the wheel.
New York City police also found 10 major vehicle issues and 40 minor infractions.
