A DRIVER allegedly four times over the legal limit ploughed through a roadwork zone on a rural road in Sydney's north west overnight, leaving a trail of destruction and a 60-year-old worker seriously injured.
The man, 41, was driving north on Wisemans Ferry Rd, Cattai, at about 11.30pm last night when he allegedly sped past a traffic controller into a roadwork area, losing control and steering his Toyota Hilux into the southbound lane on a collision course for a bustling work site.
The car scattered witches hats across the road before coming to rest between an embankment and a parked car.
The 60-year-old man suffered severe injuries to his leg and pelvis, as well as internal injuries, and was treated at the scene by paramedics before being airlifted to Westmead Hospital in a serious condition.
The force of the collision trapped the uninjured driver inside his damaged Hilux for a short time but he was soon freed and questioned by officers from the Hawkesbury Local Area Command.
The man refused a breath test at the scene and was immediately arrested and taken to Windsor Police Station where he underwent a mandatory breath test, allegedly returning a reading of .211- over four times the legal limit.
He is expected to be charged with a number of charges, including high range PCA.
Wisemans Ferry Rd is closed in both directions while officers from the Crash Investigation Unit conduct an examination of the scene.
The investigation is ongoing and anyone with information regarding this incident are urged to contact Crime Stoppers on 1800 333 000.
