I have downloaded two different hazard perception apps and they very much seem to work on a different system. What is clear is you don't just click once for each perceivable hazard. On one app your supposed to click 5 times for the "real" hazard in the clip and non others count, plus you must not click too many times.

The other app doesn't explain how the hazard clicks work and im only getting 10-15 out of 30 and sometimes I click too often. This just makes no sense to me.

Hazards are very subjective and I don't know which ones must be accounted for and which ones must not. In real life ALL need to be accounted for.

plus some hazards progressively get worse and I am supposed to click more as it progresses but it doesn't state in what increments. This testing system is utter madness

hazards aren't my problem, I have been driving for almost 20 years, I very much know what a potential hazzard is but I just don't know the rules of the software. Can anyone explain the real system, or recommend an app that replicates the real test?

The instructions are shown at the start of the test (the same intro video is on YouTube)


Basically you click every time you see a 'potential' hazard...and then click also if a potential hazard starts to become a real hazard (the main hazard of the clip)

Just be aware that you can click too soon on the main hazard, so its advisable to click once as soon as you see it, then again a second or so later just incase your first one was too fast.

Just don't go on a click frenzy cos you'll end up with zero marks for that clip.

Yeah that's pretty much what I said, it's not straight forward is it. It's not explained properly at the start of my mock tests so I was worried it would not be explained properly on the real one, plus what is the point of practicing if the system is different.

If I was taken out on the bike I could point out every potential hazard to the examiner and explain why it's a hazard. Plus if I miss any I can explain why I do not consider it a hazard. I can't do this with a machine. For example on one of the mock test apps a kid was cycling alone with the flow of traffic, but on the pavement and with a grass verge of about 10-15 yards wide. I do not consider that a hazard, sure ill keep an eye on him but at that point I would consider on coming traffic more of a potential hazard. According to the app the kid was a hazard yet the oncoming traffic wasn't. you can't state your case to the computer can you?

If I click on every hazard its too many and I get disqualified. If I don't click on enough I fail. And what I consider more of a hazard than another the computer thinks otherwise. So to me it's very much pot luck if i pass

if I knew the criteria that the software uses to decide what's a hazard and what isn't I would pass no problem

it feels like I have been invited to play a game but no one is willing to tell me the rules
thanks for the heads up on you tube, ill go take a look. I don't suppose you could give me a direct link to that video could you?

Well, it is a joke to be honest and its about time it was scrapped.

But, you have to 'play the game' if you want to pass...and that's by doing what I described above. I did and I got something like 68 out of 75, which was way way above the pass mark.

Basically every time you see a potential hazard....click (once only for each) this includes bikes, pedestrians, cars at junctions..the lot....but the main hazard will be blindingly obvious....like a bus just pulling out into your path......you will have already clicked once when you saw the bus looking to pull out as it was a 'potential' hazard...but then the bus pulling in front of you becomes an 'actual' hazard so you click again. BUT,to be on the safe side, when the obvious main hazard comes along click again a second after, just to make sure your first click wasn't too quick and missed the scoring window.

It sounds complex but really it isn't as long as you follow the silly rules to the silly game.

From memory I think on average I clicked about 7 or 8 times per clip....about 5 or 6 clicks for 'potential' hazards and a couple for the 'actual' hazard.

Oh...and the 'potential' hazards are obvious ones too....they arethings like kids running along the side of the road,cars indicating to pull out, cars approaching your road from a side junction, a school crossing, kids on bikes, cars parked on the road with hazard warning lights on etc etc........not little things like traffic lights, trees blowing in the wind.

Personally I wouldn't click for normal cars just passing you in the opposite direction, cos if you clicked for every car it would be too much....and ill tell you now...none of the hazards are cars coming towards you that all of a sudden decide to hit you head on for no reason. The hazards with cars are normally ones where they approach from a side junction and just pull out in front of you....same with the silly kid on his bike who does the same....and the van etc etc.

The practise software I used was by LDC driving school and I found it to be very similar to the actual test - hopefully this is one of the versions you have. It got me through it.

On the software you should be able to review your clicks following the test, along with the 'click catchment areas' giving graded points according to how quick/slow you are in spotting the hazards. This should give you a good idea of how you can pick up points without clicking too much.

I sometimes get 'lazy finger' and click the mouse unintentionally so I held the mouse on its side during the test to avoid this, another tip.

Oh and don't forget...ONE of the clips has TWO 'actual' hazards in it, so watch out for that.

The hazard perception test is bloody stupid. I got 35/35 last time i did the theory, and barely passed the hazard perception, not because i couldn't spot the hazards, but because the way the test software works is completely opaque.

Why isnt it left click for potential hazard, and right click for actual hazard for a start, would that be so hard to implement?

And when i was using the practice software, i kept getting crap marks because i was clicking when i actually saw the potential hazard, and not when it THOUGHT i should see it (which was apparently a few seconds later).

Its a shambles. Just try to get through it.

there's two I have on my phone, ones simply called hpt1 and hpt2 the app icon is a learner "L". the other app is called free hpt practical test. the latter doesn't explain what I did wrong at the end, it just states there were 30 hazards I should of got and I missed nearly all of them, despite me clicking too many times on one of them. I mean how can I have clicked too many and not enough on the same test

the other app shows at the end that I need to click 5 times as the hazard is progressing. to get these clicks timed perfectly really has absolutely nothing to do with riding or indeed perceiving hazards, it's like a very badly designed video game.

it's sounds like the first app I have is the same as the test and the other is just something completely different. problem is I can't really practic as once I have done one clip once there is no point doing it again because I know when the hazard is coming so I need to download more video clips. I downloaded 10 and that cost me £4 for the privilege. it tool longer to download than it did to take the mock test. I have done it a few times but because I have already seen the clip I know what's coming so it's pretty pointless really

the sideways mouse idea sounds great, I will try that
ill have a look for an LDC app to see if they have one for Android

The way it works is that in each clip (bar one) there is one hazard. There is also a scoring window. The scoring window and the hazard sort-of line up. When the hazard starts happening (in someone's opinion) the scoring window opens and at that point a click is worth 5 points. This then counts down (behind the scenes) 4, 3, 2, 1, 0. By the time the hazard is really obvious the counter is down to about 2 or 3.

Clicking potential hazards does nothing for your score *except* gives you the possibility of getting 5 points *if* that potential hazard leads to the real hazard in the clip and the scoring window has opened at the point when you clicked it.

If, however, you click when the hazard is in its infancy and the scoring window hasn't yet opened and you don't click again at any point in the clip (thinking you've already snagged it) you will score zero.

So what you're relying on is that your opinion of when a thing becomes a hazard lines up with the opinion of the person who put the test together. This is why you're advised to click a few times as the hazard develops - just in case you were too soon for the 5 points, clicking again should at least ensure you score 4 or 3.

Click too many times and you're disqualified from the clip. This is why I would advise against clicking every single dog/kid/bicycle you see on a clip before it's done anything to suggest it might actually be the hazard. Click some if you like; it will probably do nothing for your score but increases the risk of you getting disqualified. Maybe it is the hazard and maybe a click then would be worth 5 but it's a judgement call - not whether you think it's a hazard but whether you think the software thinks it is. What you've got is a fairly basic binary algorithm enforcing what is nothing more than the opinion of whoever set the test.

As long as you're quick enough to spot the bicycle that wobbles out in front of you at the point it looks like it will become a danger you should at least get 4 points and 4 points on each clip is comfortably enough to pass.

FWIW, I got disqualified from 2 clips and passed fine. So if it happens don't let it put you off.

And as Puma says - one clip has 2 hazards in it - so don't just sit back when you've spotted one and wait for the next clip because you may completely miss one hazard.

This was exactly the same as the real test for me, with a lot of the same questions, I did a practice before I left for the real thing, and passed Thumbs Up

for hazard perception it's
Click once when you first see a hazard (lose points if you're slow)
Click again when the hazard is closer or developing
Click again if the hazard gets severe

Don't spam it, I clicked like 5 times for one as I thought it was getting more hazardy as I got closer, and it skipped it for overclicking Thumbs Down

This is a very clear and concise explanation. Are you 100% this is how the system scores you? I'm not doubting your knowledge, it just that both my phone apps are different to this. I have just downloaded another one but have yet to try it

if what your saying is the actual system they use i 100% understand now, all I have to do is find an app that uses the same system so I can practice

its daft that people bring apps out and say they are official but after buying them it turns out they run on different rules

https://www.theorytestadvice.co.uk/hazard-perception-test/about-the-hazard-perception-test.php

Only spotting the *actual* hazard earns you any points. It is unlikely but technically possible to only click once per clip (twice in the one with 2 hazards) hit each scoring window at the 5-point mark and score 100% for the whole test. I wouldn't advise you try it but in principle it can be done.

Some of this data might be a little out of date (re: number of clips/hazards etc) but as I understand it the principle is still the same.

thanks mate, it's all very clear to me now, I'm not stressing about the test anymore. now I know the rules I can play the game

if anyone reading this is looking for a good app for their android phone I have tried quite a few and this one is clearly the best out of all the ones I tried. it's £2 and in my opinion well worth it. it has 10 hazard perception videos and loads of theory test questions. it's very well put together and you can customize it more than any other app I have come across. you can set it so when you have answered a theory test question correctly x amount of times it doesn't ask you again. loads more other options. it's a really good easy to use app that from what I can make out follows the exact same rules as the proper test which obviously is a must Smile

One more thing... I would expect that in order to get 5 points for a particular hazard you have to have clicked it at the "there's a dog, it might run into the road" stage rather than the "oh that dog's running into the road" stage. This means that you have to have clicked the potential hazard rather than the actual hazard - the approach then becomes a balancing act between clicking anything that may become the hazard you're interested in (+ a few more clicks when it actually happens) and clicking too much and getting disqualified from the clip. What constitutes "clicking too much", and the point at which the hazard becomes worth any points are judgement calls made by the person who set the test and you don't get to know either. So it sort-of becomes luck as much as judgement.

I just want to thank everyone on this thread for helping me out and especially angryjonny as your advise helped a lot. I did my theory test yesterday and despite only having 4 hours sleep and almost falling asleep on the train I made it to the dsa centre and passed Smile
