Hazard perception test explained

Hazard perception test is the second part of the UK theory test

Hazard perception test is the harders part of the UK Theory test. Hazard perception test evaluates how well a learner driver is able spot and react to a hazardous situation on the road. Detecting a potential hazard early enough is an important skill that all drivers should have. Good hazard perception helps prevent road accidents and save lives.


What is the Hazard Perception test?

Learners will watch fourteen one minute long hazard perception test video clips (nineteen clips for lorry and bus candidates). Hazard perception clips are computer generated imagery (CGI) and filmed from the perspective of a passenger car driver. Learners have to indicate, usually by clicking a mouse button or touching the screen, when they observe a developing hazard. All of the hazard perception clips will include one developing hazard, and one will include 2 hazards. The sooner the student reacts to a developing hazard, the more points are scored. Points are from five down to one, with no score if the examinee reacts too late.

Hazard perception CGI

What does "hazard perception CGI" mean? CGI comes from Computer-Generated Imagery. CGI clips replaced the old filmed hazard clips in the hazard perception part of the theory test on 13 Jan 2015. The reason why they changed filmed clips to CGI clips was that the image quality wasn’t clear enough.

Differences between old and new hazard perception CGI clips

Here you can see a picture where on the right is an updated hazard perception CGI clip.

These new CGI clips looks clearer than the old ones. Even the clips are now CGI, there are no other changes in the test.

I am not an experienced driver as some who have posted, but have the same problem. I have NOT ONCE failed to spot a developing hazard on any of the practice tests I have completed yet I have failed every test due to marking the hazard too early. I have also made notes on what seems to constitute a "developing" hazard and find inconsistency even within the context of the DVLA test. I realise there is little point arguing with this as they will not change this test any time soon (certainly not before I take it), but I have not seen anyone praising the accuracy and efficacy of this test as a means to improve road safety. It seems to have been actively designed to arbitrarily punish examinees with good reactions and awareness.

Passing this test would seem to require knowledge about how to pass the test rather than relying on one's own awareness and common sense. This is a sure sign of a flawed test. I am now trying to determine exactly how many times I can flag before the test considers that I am cheating. This seems to be the optimal strategy to pass. Click as soon as you notice a hazard developing and then click every second or so up to a safe limit where you will not be failed for cheating.

The CGI part worries me even more as this surely just increases the scope for an arbitrary determination of when a hazard develops.

Basically.... Grrrr


Yes, I have done it also too early. Just need more practise.


Once you learn it, it's super easy to detect the hazards on time. Thank you for this service, helped me a lot! Just click when you feel you should soon react. That's my advice.


The easiest way to do the test is to watch for developing hazard, then click, then wait a second then click, then when ya at the hazard click, that way ya guaranteed points for the hazard, see how many times ya can click on one of these practise tests you'll be surprised. at least 10. and theres only 1 hazard on most clips, so 10 clicks is more than sufficient,


I have failed twice now and some of the hazards are so blatant but its scoring in the zone. I am surprised if you can click up to ten times. This is another money making scheme for the government and you just have to be lucky on the day.


I got accused of an unacceptable manner after just 3 clicks?! fair test? NOT!!


I would like to say that this site is really helpful and really good for passing my theory test thank you so much for this lovely site. Here are those new CGI hazard tests and they helped me a lot.

Mr khan

Excellent test site and it's very helpful for learners


I found the best way to practice was to just do the real test and if you fail, just do it again after claiming benefits from the government. they'll never know


a very british way of thinking hahaha


i never practiced i just went and passed 1st time so it does work

Eddie Saunders

Well I've had a full car linence since 1988 and a full motorcycle licence since 1996 however, I need to do the Hazard perception & Theory tests as I am imminently training to drive LGV.
The problem I have with the hazard perception test is that as a motorcyclist, I'm seeing and reacting to hazards long before the DVLA's scoring "window" opens, I'm seeing hazards that are very real to me but not the ones they want me to see so I have to be careful not to click too many times... it's just a nightmare, I really have doubts about whether I'm going to pass this first time.
I have made some videos about how I think these tests are not a fair representation of either someone's ability to avoid hazards or of their roadcraft in general and will maybe put those on youtube and post a link in the DVLA twitter feed.
I honestly think they are just a good way of getting the extra test fees for the re-takes.


I am also a biker and now doing a car licence. I also see hazards too early and while I consider myself a very aware rider (and car driver instructor confirmed) I have failed my hazard perception once already. I was shocked and re-taking test tomorrow


I know how you feel. I am not a biker but have been driving since I am 16 and was also shocked to see that I had failed the hazard perception. I was more worried about the multiple choice, which turned out I got 48/50 correct. The hazard perception test is very disciving, as at the begining they say that if you click too many times, the computer will think that you are just "clicking away" and you will be scored 0. There were a few occacions when I clicked on a potential hazard before the computer window opened, and therefore the computer did not recognize that I had already seen the hazard. Not a very good test and I am another £25 down.




Im 100% with you on this, I've passed my Hazard Perception for Car, and for Motorcycle. But after driving and Riding for 10 years Im now doing LGV, Im struggling with this because I'm seeing the Hazard develop alot sooner than the test allows! It doesnt allow for experienced drivers.

Jake Scott

This is exactly my problem !!

shaz coney..

i'm glad someone actually agrees with me on this as bikers we look for things ahead of maybe wot a car would do..  i took my test today and failed by one mark on the hazard bit.. i see the hazards but  because you click to early on some stuff it marks you down which i  think is very unfair.. surly its a good thing that you see things before you are nearly on top off them.. it is very outdated  on some of the questions too... and why they ask about trailers and towing things that will be next you watch...    wot i don't get is you can pull a trailor behind a car and not have any experiance and you don't need to do any theory for that but you do for the car.. its a big money making  thing


Totally agree. I have been driving for 36 years and also hold an LGV license and I too look a good distance ahead as breaking distance is obv greater, so I find myself clicking too early. Surely it's about how you are reading the road and not how you click on a computer.

Peter Allard

I totaly agree I have failed my HP twice now, as an experienced driver I spot the hazards in advance and having no sound or engine noise is very off putting, I think a fair system for people training to be ADI'S or HGV drivers or any other professional driver would be to have an half hour commentry drive. I also reckon that £83.00 for the test is very expensive compared to what novice drivers have to pay.

Anita Dean

I to failed my HP Test ive been driving for 30 years and as you say I also spot hazards a lot earlier than an inexperienced driver. I found the position of the camera view wrong as when you are actually on the road you do have some side vision. One of the clips showed the vehicle coming off a roundabout with a brick wall on the nearside the position of the camera made it feel as though I was actually going to drive into the wall which did put me off track a bit.


I think that u don't lose pounts when react more than once to the situation as long as u don't over do it!


I totally agree with this.They are made to take extra money from people and they don't represent driver real knowledge.It is a joke.I considering if I can go in other EEA country and take a test in English.I own full licence for the last 17 years from other non- EEA European country and government in UK lets me drive only for a year before I need to take a UK test again.Why they let me drive on the first place?!!!


Holy crap. I'm exactly the same as you, I'm seeing potential developing Hazards WAAY before the "scoring window" opens up and as a result of being a forward thinker I'm penalised? It's absolutely ludicrous.


I totally agree with you here Eddie. I just sat my hazard perception test and failed! I was very conscious of not over clicking but think that my perception of the hazards started before the clips scoring kicked in so my click wasn't counted! I sent an email to ask for my results to be analysed as I am very well aware of the hazards. I agree that I failed because they want me to take the test again for the fees not because I wasn't fully aware of the hazards!

Karl s

Hi yes I have done my theory test now 5 times and due my other on the 2nd of August.however each time I go that always seem to change the clips it's really frustrating I think your right it's just a way to get more resites of people it's wrong


I am also a motorcycle rider and have found the same problem. See the hazard and count to 2 then click - seems to be working in the practices!!


This has also been my experience, Eddie - that I am spotting hazards too early and they're not being registered. For almost every (practice) test I've taken I've spotted the hazard I'm meant to, but just before the clip registers the hazard, so it's not recognised that I spotted it. The way I learned to counteract that is to click 4-5 times in quick succession at the point of the hazard, and this seems to work OK. Not ideal because I guess I risk being penalised for over clicking, but I'm not sure what choice I have? Very frustrating. I'm taking my actual theory test in 2 weeks...


I agree! As an advanced driver my hazard perception skills are far better than a "normal" driver and I can notice hazards well ahead so I have scored zero on some clips as I've clicked far too in advance but don't want to click too much to be accused of "cheating"


Agreed. It's basically testing your ability to click in the fashion that they want.
