Thompson then called the ambulance but didn't tell officers his name, and went to work as usual yesterday, a colleague told theage.com.au.
Thompson has been hailed a hero for saving the life of the middle-aged, diabetic truck driver who had fallen unconscious because of low blood-sugar levels.
The local pub in Bellbird was buzzing yesterday with the news of the rescue, with locals joking that Thompson should have been fined for not having a truck licence.
The truck driver was treated at the scene and is now recovering in Cessnock Hospital, where his condition is said to be improving, theage.com.au reported.
