The Hazard Perception test will consist of a series of film clips, shown from a driver's point of view. Before you start this test, you will be shown a short tutorial video that explains how the test works and gives you a chance to see a sample film clip. This will help you understand what you will need to do.
During the test you will be shown 19 film clips, each clip contains 1 or more developing hazards. You should respond by pressing the mouse button as soon as you see a hazard developing that may result in you, the driver, having to take some action, such as changing speed or direction. There are 20 score-able hazards in total.
Every time you click, a red flag will appear on the bottom of your screen in order to show your hazard has been noted. In order to pass this test you will need to score at least 67 out of 100.
In simple terms although you will see what you might consider to be a hazard during the video the real hazards are things that will make you change speed, direction or even stop. Identifying these hazard early will score you more points.
A-Class HGV / LGV Training School can supply you with the DSA official DVD-ROM Hazard perception for you to practice and the Official DSA Theory Test book for Drivers of Large Vehicles - which contains EVERY question which could be asked during the test.
