The problem with the hazard perception is that it is completly stupid! The computer only scores at the point just before the incident happens. If as you have been, you've been driving, you spot the potential hazard to early for the computer to score it. As I said to my instructor after taking the PCV test. 'If I got into the position where I had to react , you'd rip my head off and mess with the hole for not reacting earlier'. There is a computer game disc that will help you. As an extra joy if 'you are driving commercialy, or the main part of your job is driving', then you have to take the Driver CPC. If however you're only driving private or the main driving is concerned with enginerring ,or you only drive as a small part of the job, then you don't need it. If you can work it out, please explain to the rest of us. The best answer would be to introduce a 'commentary drive' to the test. That's how the real proffesional do it!
