A motorcyclist was struck and killed by a drunk, unlicensed driver on the Long Island Expressway in Queens — just a month after the reckless motorist was busted for driving with a suspended license, police said Tuesday.

Juan Moncada, 63, was riding his Honda Rebel bike in the center lane of the LIE and heading west near 169th Street around 11:15 p.m. Monday when a Nissan Altima, which was driven by Korey Cox, veered into his lane.

Cox, 27, was traveling in the fast lane when he swerved into the center lane, crashing into the motorcycle and causing the bike to slide along the road and slam into a guardrail, police said.

Cox’s car smashed into a fence and overturned before landing upright, according to authorities.

Moncada, who was wearing a helmet at the time, was tossed from the bike and suffered trauma throughout his body. He was pronounced dead at the scene, cops said.

Cox, who is from Coram in Suffolk County, was not injured.

He was arrested and charged with aggravated unlicensed operator, driving while intoxicated, operating a motor vehicle while impaired by drugs, driving while ability impaired by alcohol and refusal to take a breathalyzer, cops said. He was also hit with a motor vehicle violation for driving without a license.

He is due in Queens criminal court Tuesday.

Cox was previously arrested on the morning of June 28, when he was pulled over after disobeying the posted height clearance on the Queens side of the Queens-Midtown Tunnel near Borden Avenue and the East River, police said. He was driving a 2012 International truck at the time.

When cops checked his DMV history, they discovered Cox’s license was suspended, authorities said.

Cox was charged with aggravated unlicensed operator of a motor vehicle, driving without a license, failure to obey a traffic device, police said.
