A traffic jam caused by a fatal motorcycle accident on the FDR Drive may have led to a road rage shooting that left one man dead in Upper Manhattan early yesterday, police sources said.

An individual in a yellow Nissan Xterra SUV pulled out a gun and began shooting at the driver of a maroon Honda Accord at 5:49 a.m., after both cars had been diverted onto First Avenue from the jammed up FDR, police sources said.

Police sources said they believed the driver of the Honda, which was carrying two passengers, drove northbound for three more blocks from the spot of the shooting near East 117th Street. The driver pulled over at East 120th Street and died of his wounds 20 minutes later.

The victim was identified by police officials as Jayson Tirado, 25, of Manhattan. Responding paramedics said he had been shot in the torso. He was taken to Harlem Hospital, where he was pronounced dead.

There was a small bullet hole visible in the cracked window on the back passenger’s side of the Honda, which was cordoned off with yellow tape where it had stalled at an angle in the intersection of 120th Street and First Avenue yesterday morning.

The motorcycle accident had occurred about 45 minutes earlier, a few blocks away on the FDR Drive at East 117th Street. The motorcycle driver had been speeding down the southbound side of the FDR Drive, police officials said. He tried to switch lanes, but struck the center divider of the expressway and hit his head on a light pole, police said.

The man then fell off his motorcycle and was pronounced dead at the scene.

The FDR was backed up on both sides following the accident, and police officials said the dispute between the maroon Honda driver and the person who later shot him began there, before they both turned off onto First Avenue.

Police said they were looking for the suspect yesterday evening.

The shooting yesterday is not the only incident of road rage that has ended in violent confrontation this year. Last week in Staten Island, a man allegedly punched and then ran his car into a woman as she was standing beside her car after he had accused her of cutting him off earlier.

There was also an incident involving a law enforcement agent who brandished an off-duty weapon at another driver, according to published reports. In January, an off-duty correction officer fatally shot a man who allegedly attacked him. The man had approached the officer’s car and allegedly began punching the officer in retaliation for honking at him as they were stopped at a red light near La Guardia airport, according to reports. Also this summer, two men assaulted an unarmed auxiliary police officer in a fit of road rage in the Brownsville section of Brooklyn.
