A TEENAGER was struck and killed by another driver as he changed a flat tyre in the centre lane of a major western Sydney road this morning.

Emergency services were called to James Ruse Drive in North Parramatta just before 11am to reports a pedestrian had been struck by another vehicle.

Paramedics raced to the scene and treated the 19-year-old from Wentworthville, but he couldn’t be revived.

A white ute could be seen in the centre lane with a spare tyre on the road next to it, the man’s body covered by a white cloth metres away.

It’s unclear why the driver decided to change flat on the road rather than pull into the emergency lane available on the road.

The driver of the car that struck the man — a 41-year-old Turramurra man — stopped after the accident and is co-operating with police.

He was taken to Westmead Hospital for mandatory blood and urine tests.

James Ruse Drive was closed northbound as police crash investigators examined the scene.

Investigators are asking for any witnesses who have not yet come forward to contact police.

Police said they especially want to hear from an Asian woman, who was wearing a blue top, as she was travelling in a nearby vehicle ahead of the collision and may have more information.

A report will be prepared for the coroner.
