A TWO-year-old boy has died in a head-on car crash near Clarence Town.
His 22-year-old mother was driving east along Limeburners Creek Road yesterday morning with her two sons, the toddler and a 14-week-old baby boy in the back of the car.
Near the intersection with Bucketts Way, the family's Holden Commodore station wagon collided with a small truck carrying boxes and equipment.
The truck was left lying on its side.
Emergency services were called about 9.25am. They rushed the injured toddler and his baby brother to hospital, but the older boy died from his injuries en route.
Their mother is in a serious but stable condition at John Hunter Hospital, and the baby has been placed under observation after suffering minor injuries.
A Newcastle Crash Investigation Unit spokeswoman said police did not believe the width of the unmarked country road contributed to the crash.
She said initial investigations had shown there was enough room for two vehicles to pass and it wasn't a case of the car or truck failing to pull over and let the other through.
The crash was the third fatal accident in the Hunter involving a truck in recent weeks.
On September 10, a Singleton school bus was hit by a truck, killing nine-year-old Harry Dunn and injuring two other young boys.
A tradesman was killed on Tuesday after his utility crossed into the path of a water truck near Lochinvar.
The male truck driver in yesterday's crash has undergone mandatory blood and urine tests and has been treated for minor injuries.
Police spent several hours at the scene yesterday afternoon and will conduct further inquiries into the accident before preparing a report for the Coroner.
Limeburners Creek Road was closed until yesterday evening.
