The Hazard Perception Test (HPT) is a practical, computer-based test. To get an idea of what the test will look like and how you will interact with the touch screen you should not just rely on the still image examples provided by VicRoads. Although these images are from the real test, they are not particularly helpful in preparing you for the HPT.
Luckily, Driving Test VIC has a handy resource that simulates the HPT very accurately. The practice tests consist of clips of real traffic situations and require a quick response, just like the real HPT. There are 5 practice tests, each with 7 questions for a total of 35 questions.
This is the number one (and essentially only) resource to practically prepare for the HPT. You can find links to the practice tests and Driving Test VIC commentary on the appropriate responses here.
