DUI while he was employed by MTA

THE DRIVER of the tour bus that crashed in Queens early Monday, killing himself and two others, had his license suspended two years ago after he drove drunk and crashed into three people in Connecticut. Dahlia Group driver Raymond Mong, 48, pleaded guilty to driving under the influence and leaving the scene of a crash, which he caused with his personal car in 2015, records show. Mong was working at the time as an Metropolitan Transportation Authority bus driver, sources said. After he was arrested, the Connecticut state Department of Motor Vehicles notified the New York DMV, which passed along the info to the MTA. Mong was fired in 2015 for cause, according to MTA spokeswoman Amanda Kwan. He filed a grievance that was handled in arbitration, according to a source. In June, his grievance was denied. It was unclear Monday when Mong began working for Dahlia. He had an appeal left, scheduled for October. Connecticut state police records show Mong, driving a 2002 Honda Acura, rear-ended a 2004 Chevy Tahoe on the Exit 51 off-ramp from I-95 in New Haven on April 10, 2015.

The impact pushed the Tahoe into a 2011 Volkswagen Jetta being driven by a 22-year-old woman.

Mong, who was with his wife at the time, panicked and fled the scene. State police and New Haven police tracked him down and arrested him.

Barbara Wynne, the mother of Alexandra Wynne, the Jetta driver, recalled the emotional call from her daughter shortly after the rear-end collision.

“I remember her calling me up and being upset at being hit, and the driver took off. She got banged up,” Wynne said. “He was driving really erratically and he hit her and thank God she wasn’t severely injured.

“I don’t know why they would let someone like that drive a bus,” she added.

Cops slapped him with a range of charges in addition to drunken driving and leaving the scene. He didn’t have the proper insurance, was illegally tailgating and driving erratically, records show.

Three people suffered minor injuries.

Mong was sentenced on Oct. 20, 2015. He was ordered to serve 18 months’ probation, temporarily surrender his license and pay a $500 fine, according to his lawyer.

His Connecticut license was restored on Feb. 23, 2016, a source said.
