How does the scoring work in the Hazard Perception apps?

Most hazard perception clips include just one scoring hazard, one clip includes two scoring hazards.

Between 5 and 1 points are awarded for each scoring hazard, depending on how quickly after the hazard become apparent that you touch the screen (or clicked the mouse on the video) to indicate you've seen the hazard.

Each time you touch the screen a small red flag will appear along the bottom of the app's screen, the width of the screen represents the full time line of the clip:

After you've seen the whole clip you are given the option to review it and during this process the timeline shows:

  • The 5-1 scoring region of the video when you should have tapped
  • Red markers corresponding to when you tapped the - if the red markers align with the 5-1 scoring region you would score points

Though you won't be penalised for touching the screen at other times, be aware that (as in the real test) touching the screen rhythmically or randomly is likely to trigger the cheat detection system which will score you 0 points.

General Advice and Suggestions

We spend a long time looking at each hazard video before specifying the positions of the opening and closing brackets for the hazard itself, each one is placed with very specific and strict criteria – the same criteria as are used in the actual test.

A lot of people think that the aim of the Hazard Perception test is to click when you see something happening – but it is not. It is a test of your ability to PREDICT a problem occurring in the near-future, based on the evidence you see in the video frame. The Hazard Perception Test and the learning material that helps you prepare to take the test have been developed to enable less experienced drivers to gain the ability to foresee a problem that is developing which would otherwise only be acquired through experience.

You do not only need to click once per DEVELOPING hazard. You should aim to click between 1 and 3 times as follows:

  1. Your first click should be made when you get an inkling that something MIGHT be about to happen. If the thing you were thinking MIGHT happen then doesn’t happen, then this will be your only click. If this is a developing hazard and you are really good at predicting, then this click may sit BEFORE the 5 bracket – in which case it will score nothing, or it might score you 5.
  2. Your second click should be made if the scene develops as you were expecting it to, and the potential problem looks like it is in fact going to materialise. This click will likely fall in the 4-3 point bracket, but if your first one was before the 5 bracket then this 2nd click might score 5. If this click only scores you 4 points – then that is still a very good score.
  3. Your final "backstop" click should be made when the event is fully developed (the person that might have walked into the road, ACTUALLY walks into the road - for example). If you were not "paying attention" and this is in fact your first click, then this will likely earn you 2 or 1 points – which is a lot better than zero, but not a high enough number to get a pass if that's your average.

In general, you should not EXPECT to score 5 points on every hazard – that's just unrealistic. However, you should aim to score in the 5,4,3 range for every clip – and so long as you are doing that, then you will pass the learner hazard perception test quite easily.

Note that the aim of the learning material and the hazard clips we provide is not JUST to get you through the test. It is mostly intended to help you improve your hazard perception skills so that you will be a safer driver when you qualify (and as a by-product help you to pass your Hazard Perception test). That is why we use only REAL driving situations in our videos and why we provide a very large number of them – simply put it is the best way to improve your Hazard Perception skills. However, as a by-product of there being a lot of real-world situations, some of them develop over a long period and some of them develop over a much shorter period. Some will be obvious, some very subtle. That's the nature of real-world driving too – and that is what we are preparing you for.

The DVSA's clips are computer generated and they have complete control over the develop-time of each hazard. The test clips are not that realistic (you will likely find them very sterile compared to real-world clips), and so you will probably also find them much easier than our real-world clips – but, as our duty is to prepare you for the real world, not just the test, we strongly believe this is how it should be. Train hard – and the test itself will be easy.

    After failing the mock test I looked to see where I went wrong and most of the clips showed the exact same hazard I had clicked but still failed. I practiced literally 30 times and only passed once with 45 marks. I failed 29 times I am not able to understand why. I fully understand the importance of the hazard perception however I think the computer system is failure in order for it to realize that the correct hazard has been clicked. Not sure how can I get this right.

    Exactly same thing happened to me. I thought I was getting zero and one in most of them for a reason. Looked at the reviews for each clip and clicked on the same place for most! It's a good app to practise but not very good if you can't tell if you're getting them right or not unless you review. Doesn't fill me with hope for the real hazard perception!
