The Hazard Perception Test (HPT) is the second part to the theory test and is just as important to practice as the theory questions.
Here's how it works...
You will be presented with 14 video clips of real driving situations. Each clip will last for 30 seconds and during that time a number of hazards will appear on the screen. When you observe a hazard you need to register the observation by clicking the mouse button. This will tell the computer that you have seen the hazard. The sooner you click the mouse button the better your score will be. Scoring starts at 5 then 4... 3... 2... 1... & finally 0 for those hazards you respond too late to or miss completely.
13 of the clips will score you on a single hazard and in 1 of the clips you will be scored on 2 hazards. Therefore you will be scored on a total of 15 hazards each with a maximum score of 5.
15x5=75 points maximum score
The pass mark is 44 out of 75.
Thinking of cheating..... Think again!
If you were thinking that you could just sit there clicking the mouse button and hope that you click at the right moment, then think again. The software used to register your clicks is clever and will detect you clicking too often or in a rythmic pattern and score you a 0 for that clip! So be warned you can't cheat the system.
Practice is always the best way. There are a number of training tools available at very reasonable prices.
