Shocked Vaucluse residents found a 39-year-old ute driver dazed but uninjured after he left a trail of destruction on Old South Head Road on Tuesday night.

The man, who police allege was drunk behind the wheel, crashed his white Ford Ranger ute into three parked cars, one of which then smashed into another parked car.

Including his own car, that left five cars with a range of damages.

A silver four-wheel drive had its front bumper entirely ripped off and a silver hatchback was left with a severely crumpled bonnet.
