NSW family in head-on 'drunk driver' crash

A couple and their two young children have narrowly avoided an Easter tragedy after a head-on crash with an allegedly drunk driver in NSW's Hawkesbury region.

A 29-year-old Stanhope Gardens man was travelling with his wife, two-year-old son and one-month-old daughter, when the crash happened in Webb's Creek on Friday afternoon.

All four were uninjured, but all the airbags in the car deployed in the crash.

The driver of the second car, a 54-year-old Lower Portland man who was also not hurt, returned a positive reading of 0.120.

The man was later charged with mid-range drink-driving and driving an unregistered vehicle.

He was issued a field court attendance notice to appear before Windsor Local Court on May 14.
