mtbc | Driving hazards game

I took my driving test in England well before the Hazard Perception Test was introduced. It is a simple computer game in which one watches video, as if from looking from the driver's seat, and must push a button to register that one has noticed each hazard that develops on the road ahead. It sounds like a peculiar game in which the challenge is not to notice the hazard but instead not to register it prematurely, not clicking when it is merely a situation to keep an eye on. It may work best to push the button at around the time even a driver with poor foresight would actually act. One is warned not to over-click but an alternative might be to click a few times while a hazard remains apparent. I wonder how effectively this test turns out to provide additional information about if a new driver's situation assessment is yet adequate. The test is not a precondition for taking driving lessons; our eldest was about ready to take the on-road test before getting around to taking and passing this test.
