We're talking emergency stop, not slowly stopping. Some civilian appears on the middle of the road ahead of you. Would you go consider "Oh what do I press first?" or would you immidietly hit brake alone?
@potsu nfw you're going to develop .5 second muscle memory to hit the brake then depress the clutch before the vehicle stalls. If you fail and you're in an emergency maneuver w/o an engine you're screwed. Stupid.
He is half right and the other half is complete nonsense. I will explain. I will take the bad half first. Wheels locking up. This is actually performed by the ABS system. And it is very good at it because it is constantly measuring the RPM of the wheels. So you don't need to use any other control such as the clutch to stop the wheels locking up. It is not required. And wheels not locking up doesn't shorten the stopping distance. This is the myth that a lot of people have in relation to ABS shortening the stopping distance. It doesn't What ABS does is allow you to still control the car when turning the wheels so you can continue to brake whilst steering around an obstruction without losing steering control. First half: He is mostly right here. One method of slowing down a vehicle, which certainly used to be taught many decades ago, and I don't know if it still is, is that you can step down through the gears and reduce the amount of brake usage. Try it, travel at 30 miles per hour and then put the car into second gear and see what happens. So keeping the engine engaged to the driving wheels by keeping the clutch up can provide an additional braking effect. So it does make sense to keep the clutch up. However, keep the clutch up for too long, and as the car slows down it will eventually stall. But does that really matter? And as the clutch and brake are operated by different feet, there is no reason why you can't depress both at the same time. The important thing is to hit that brake pedal as hard as you can so that you are applying the maximum amount of braking force possible to the wheels. The fact is, much of the time people don't apply enough brake pressure and that is why systems such as brake assist have been invented. These recognise that you have applied less than the maximum brake pressure possible and the system will apply the extra pressure for you automatically so that the maximum pressure is applied to the brake pads.

No, not at all. If you're doing 250kmh(about 150mph) and there is a van or lorry pulling in front of you, you have to go down to at least 60 very quickly, these are clenching your ass moments lol
@@gyula6516 If you have a car, which is capable of going 250km/h and slowing down fast, you'll still experience more Gs, if you slow down from 60 km/h to 0. Because Gs are related to acceleration or deceleration, which can be computed as the change in velocity over time. And if you are going 60, you'll be able to slow down in significantly less of a time than if you are going 250 km/h and slowing to 60 km/h. Simply because the breaks won't be as effective at higher speed.
That's actually a very good stop 👍🏻. During emergency braking, it doesn't matter whether you go clutch first or brake first. The aim to respond very quickly and stop fast.
Definitely break, if you don’t clutch your car just goes off* and you still have an emergency break, that’s f you don’t break and just clutch, literaly nothing will happen, you won’t slow down at all, not even the engine is slowing you down at that point
It does matter- by putting the clutch down first the car will actually speed up- that’s why brake first clutch is to stop the car stalling- have you taken a driving test in the uk?
Nah if you suddenly push brake when you are driving at 20 or less you should hit clutch first then brake because if you do otherwise the car will be turned off kinda . If you are going at more than a 30 then yes brake first@@cookz-bs10gaming
@FuckashimaMonaCher hes trying to say if you have done that in india meaning another country… doesn’t matter if we ain’t in india it’s another country lol
@@gauravbassi8255 if only we had these kinds of driving tests before getting a DL in india.

So darn important to know the emergency brake! The instruction lady has a really calm voice and demeanour, I would have liked to have her as my instructor too.
@@weisdog2026 she wasn't encouraging the driver to run a red. That red light didn't apply to them, the pedestrian was not on the road nor did they have a zebra crossing.
@Zinnia Lorant-Pryor the pedestrian was close enough to reach the car before she could clear the crosswalk. Idk what the laws in Britain are but in the US the pedestrian always has the right away, even if they aren't in a cross area. So if that pedestrian decided they wanted some of that sweet sweet insurance money they could've walked a little faster or dove into the car. People are crazy in US so I think that's why people say the instructor was in the wrong for giving the driver issues about stopping.
@@dynamicskrillz7898 what I gather as a difference between us and uk (as someone that lives in England) is that pedestrians here typically don't cross the road until the cars are at a far enough distance to make it across with ease or stopped, if the learner or any other driver in the same situation were to continue driving past the crossing the pedestrian would've stopped, it's just how things are, the red light wasn't for the people turning onto the road we just have 2 sets of lights on some roads so people at junctions or far back can see if cars from either side of the road are about to go
Are u daft she’s incompetent as f*ck Panics bare Is even asking here what comes first the clutch or brake… if u stop in gear without ur clutch in which is what an emergency stop is… ur in gear driving and slam to a halt, if ur clutch is up u will stall and the car won’t stop it’ll jump forwards..
Hit them both at the same time as hard as possible. Here in Germany you are taught to do so and the engine has to keep running for you to pass the test. If you keep the clutch not pressed for too long the engine will even pull you a bit further against the force of your brakes until the engine shuts down. So especially at slow speeds the risk of stalling the engine is much smaller if you hit both at the same time. At higher speeds on normal cruising I'd say that you'll probably be in a gear that is reving relatively low to save fuel. In that case the engine braking is very weak.
That's kinda stupid, nobody does emergency stop on command, you have to decide yourself if it's necessary. And you do it the way it's easier for you to control the car, not using some specific algorithm.
@@ldmtagthe specific algorithm is to stop as quickly as possible without stalling the car (in case escape is required). Hence mash both pedals and let the ABS do the rest. Short of some fake-kid popup contraption hidden on the course, how else would you test their judgement when to emergency stop?
The fastest, safest and correct way of stopping is first brake, then quickly after press in the clutch. As long as you press the clutch in time the car won’t stall. On motorcycles you would first use the front brake, and whilst breaking start using the rear brake aswell, then clutch in
Professional driving instructor here: Strongly recommend switching to AM radio first when emergency breaking to ensure any and all public service announcements are considered before applying pressure to the break. Also consider your personal hygiene in these stressful situations, you may need to apply extra deo before completing the stop.
@@Rma0613 more like 30 but depends on the braking capacity of vehicle. because if you hit brake first you wouldn't have enough time to hit clutch before engine shutting down.
Doesn't matter what you do first. If it's a emergency stop, then whatever you can do first and fastest is what you should do. Just remember to check if there's anything behind you so you don't hit it when continuing to drive forwards!
@litalitvinaite891 sometimes people don't understand why you stopped suddenly and will try to swerve around you. That's why it's important to check your blind spots.
When I was learning (17 years ago now), I kept trying to do the stop like the highway code described, namely smooth and firm on the brake then clutch. After a few goes, my instructor told me thatjust hammer the brake as hard as I can, depress the clutch and trust the ABS. If you stall you stall, but you stop the car and that's what's important.
It's called engine braking my guy and it helps stop the car faster, but it's only recommended in emergencies for cars because it could damage the engine, although most of trucks and semi's have an engine brake it's usually common among them
You only use brakes when emergency braking. The reason is due to engine break working too and when fully pressed in break ABS will activate which will make sure you still have traction when braking. Engine will automatically stop using the engine brake when ABS activates so no need to hold clutch. Holding the clutch with brake is far more dangerous, expecially when going high speed since you can't manouvre anymore as you lock of everything except the brakes, granting no traction.
@@channel4ferrets Not really, you can stall if you lock up your wheels. And even if you have ABS, let's say you are in 5th gear going 60 mph, if you have to emergency break, you can break until you go down to ~45 mph, any less and you stall and then your breaks go out because the brake booster doesn't get any power.
@@bariczarnold3009Not exactly. The brakes are technically still usable, most people just aren't strong enough to use them. Not sure if ABS works while the engine is stalled
Yes but your forgetting you can stop a car with the engine and gearbox. The idea is the stalling engine will help stop the car quicker. Plus if your brakes fail atleast there will be a few mph knock off before hitting something.
@@PremiumJutub You have an engine break pedal on trucks. In the old days it was common to teach people to slow the vehicle with the engine. Thats why older people are so slow when approacing junctions and stuff because that were taught different methods.
Slam the brakes on as hard as you can, depress the clutch at about the same time, and check that you can feel the ABS pulsing in the brake pedal, if you can't you're not braking hard enough. The common mistake is for people not to hit the brake pedal hard enough and the vehicle does not stop in the shortest distance possible. If the ABS has activated then you have applied the maximum amount of braking force possible (for the road conditions). But it is important to note that ABS does not help you slow the car down.
@@sylviamcgeary3587 The point is to stop as fast as you can. ABS sort of "limits" your brakes so that you can retain control over your wheels while braking hard. If you don't hit that limit, you're not braking as hard as you can / not stopping as fast as you can.
Yes the main goal of abs is to keep control of the vehicule while breaking. But its also true that it makes the car stop in a little shorter distance because the friction is better when the wheel doesnt slide on the road.
@@4cemils The friction isn't less when the wheels are rotating. The friction is higher when the wheels are not rotating and they are sliding. Hear the screeching noise and heating up of the tyres? That caused by increased friction. ABS works by repeatedly releasing the brake pressure, which means the braking force is applied for less time than compared to no ABS system present. When the brake pressure is not applied, the car is not slowing down.
@@deang5622 You're wrong about the friction aspect. There is a greater stopping force due to friction when the wheels are rotating than when fully locked. When the wheels are rotating, the surface of the tire and the roadway are (effectively) stationary relative to each other, as the surface of the wheel is rolling past at the same rate as the road is being driven over. Due to that, the braking force is via static friction, as opposed to dynamic friction (sliding) when the wheels are locked. The reason for the heating up of the tires when the wheels are locked is that all of the frictional force is being applied to the same surface of the tires (since they aren't spinning), which causes that section of tire to heat up very rapidly. Armed with that knowledge, we can ask whether there will be greater braking force when the wheels are rolling (static friction), or sliding (dynamic friction). The static coefficient of friction is larger than the dynamic coefficient in almost all scenarios, and is between tires and roads. Given that, we can see that you will be able to generate larger braking force when the wheels are rolling. With respect to ABS potentially increasing stopping distance due to the pulsing of the brakes, you're technically correct, but only compared to theoretically optimal braking. The optimal braking maneuver (based on the above paragraphs) is one where the brakes are applied such that the wheels are being slowed as much as possible without breaking traction with the ground (without sliding). A highly skilled driver with sufficient experience with their car's braking capability could apply the perfect about of braking force to sit just below that threshold, and thus be applying maximal braking pressure the whole time. However, for the vast majority of drivers (and the amount is increasing as ABS becomes better and better) ABS will outperform their capabilities.
The reason it’s brake and the clutch is because when you press down the clutch, you take away the engine’s vacuum, causing less rolling resistance to the drive wheels since the transmission is no longer connected to the engine when the clutch is depressed. You’ll notice this is you’re going down the highway and you only press the clutch in, it’ll start to feel like your car rolls slightly faster, because it is. In an emergency situation, the goal is to stop immediately and cease all motion of the vehicle, not give it the opportunity to roll faster.
What do you mean the clutch takes away the engines vacuum? Engine is gonna be creating maximum vacuum when you are off the throttle regardless of if you step on the clutch or brake, I don’t get what vacuum has to do with this
In this instance the millisecond you save braking first enables the car to stop sooner / could be the difference between hit or miss or life and death. Brake, clutch neutral handbrake then continue if you haven’t hit anything.
Brake, that is what you want. In worst case the engine turns off, if you use clutch too late, but in emergency that does not matter. In best case like downhill the motor even supports breaking.
In a real emergency stop it does matter so long as you stop and are safe. No point thinking which foot first, you may stall it at that kind of stop especially if you are braking harder then this. But generally if your braking it’s brake first
For regular stop - break first. For emergency stop it is more complicated because you don't want your car to stall. If your car stalls you lose power steering and brake boost. Of course, the priority is also to start braking ASAP, so best is probably to hit the pedals at the same time, like the woman in the video.
Depends on your speed, and if you're going downhill or not. If you're going downhill it's far better to not even worry about the clutch because you'll loose aid from engine braking. You aren't going to stall until you're below 1k rpm anyways and the booster allows you to brake again after the car is off. Plus once you stall you will be going slow enough to yank the emergency brake.
@@tinyokami968 Emergency braking is traction limited (your brakes are more than powerful enough). Engine braking would't provide any additional support. Also, engaging emergency brake during braking is very bad idea as it completely locks up your wheels which takes away the control of your vehicle.
In any modern car you will have maximum brake force the moment you touch the brake, even at motorway speeds thus you depress both pedals simultaneously in a panic stop otherwise you are working AGAINST the inertia of the whole drivetrain and engine. this can greatly decrease the effectivness of the ABS doing its job. think of it this way: the ABS is trying to stop each wheel as close the the grip limit as possible and oscillates around that point several times a second, sometimes also overshooting a bit and stopping a wheel/the wheels completely for a short time. if the engine is still connected in that moment it also stalls the engine, then suddenly realeases the brake force a bit and the engine starts turning again. this happens several times a seconds. you can imagine it can greatly offset the effectivness of the whole system when you are dragging the engine with you all the time this way. of course, this only applies to a full panic stop. if you only do normal braking you dont press the clutch (until necessary for a smaller gear/stop).
How does pressing the clutch make you lose control of the vehicle actually in the specific situation of breaking suddenly it would create less effort on the breaks making this the reverse of true
@@PhysicsOperator you have engine breaking in a car, when you press the clutch in it frees the engine so you use that engine breaking to help you slow down
@@Caleb_Carter309 that depends on a lot of things but best thing on low speed is tk use clutch first, anyone saying otherwise is an idiot who doesn't know how to drive and never asked the right questions to their instructor.
@@Alex-ny1qg I wouldn’t say clutch first for low gear - perhaps simultaneously (if you understand your car). It’s better to just teach people to brake and then clutch as it covers all scenarios for maximum safety
For immediate stop in a manual vehicle, you step on the clutch until it gets in and then you step brakes, until the car stops immediately but for ordinary stop you step smoothly on the brake pad without clutch because it will help the car to be stopped by the gear you're in.
Both at the same time. Very few drivers have the skill to correctly work the pedals for an emergency stop, especially when it's a real emergency. In theory you should press the brakes first and then the clutch only when needed to prevent a stall. In most modern vehicles that window is incredibly small and not what you should be worrying about in an emergency stop.
It is a bit mad in terms of the test. It's like, you move over to the right to go past a traffic control (give way), you can see from that point the road ahead is completely clear and you know from your previous position there's nothing behind or beside you, but you can still fail for not checking the left blindspot before moving back to the left, just in case a cyclist has magically teleported next to you in those 2.5 seconds.
From the words of a supervising examiner. On a car that is fitted with abs you just press them both at the same time for a controlled/emergency stop. As long as you stop promptly and it's controlled an examiner doesn't really care.
Ideally Brake first then clutch or if you are an experienced driver you can do both at same time in emergency situation but that would reduce your reaction time by some good milliseconds which is very crucial.. so its better to break first then clutch
Someone really needs to test this, and they probably have. I always wonder at low speed and gear if the engine intertia and flywheel/clutch assembly mass would actually hinder the cars deceleration. Consider if you revved the engine near to redline, let off the throttle and during the rev hang (i.e. before the revs drop to idle) dump the clutch. You'd get a jolt forwards. This would be similar to having the clutch engaged and slowing the car down so that the RPM falls faster than the engine braking would cause it to. This would only apply in first and maybe second gear if it is an especially short ratio gear.
Every driving instructor will say ‘I will not get you to do that again’ unless there are external circumstances which would make the instructor feel the need to make them redo the emergency stop. It has nothing to do with whether or not your emergency stop was good.
Emergency stop is just that, first instinctual reaction to stopping the car and it needs to be quick, reason why a lot of instructors say the clutch doesn't need to be pressed. Not good for the engine but good for reaction time which in an emergency is vital.
..when breaks are pressed after applying clutch first ..then breaks really become strong ..cuz .. Engine is disengaged... .. while if breaks first used to reduce speed .. it'll take time as engine is also connected.
Clutch, then brake. If you are breaking and then need to get out of that situation you can pop back into 1st and skirt off before getting slammed into. Can't do that if you've stalled it out
Incorrect because then your coasting for a short amount of time which isnt good you should only press the clutch when you shift gears or when you break but you should always press the break pedal first
AIGHT SO, some people aren't getting the point of this Its an EMERGENCY stop, ie someone has just walked out in front of you without warning such as from behind a parked car. You want to stop AS SOON AS POSSIBLE so to kill your speed quicker, you want engine braking for as long as possible therefore you dont want to be putting the clutch down immediately. You want to be slamming the brake firmly, then clutch just before you come to a stop. As people have pointed out, on a test you'll literally only be doing this from a max of like 20mph so its not seen as a major issue if you push the clutch down first BUT the principle of it and the reason its on the test at all is so that you know brake first clutch after when this potentially happens at much higher speeds ie on a motorway or A road. In that case, the engine braking makes a big difference so instructors want you in the habit of leaving the clutch as late as possible so its second nature in AN EMERGENCY
P.P.S.: I feel ‘emergency stops’ within a city and a motorway are fairly different scenarios. Within a city an emergency stop more frequently is exactly that, a stop, ie, you’ll brake until you have come to a complete stop. At motorway speeds, the vast majority of the times it is when somebody suddenly moves into your lane (controlled or uncontrolled) that you’ll need maximum brake power but you very rarely would keep braking until a complete stop (additionally you more likely also have time to steer your car away from the obstacle). This additional time also enables you to think “Oh, I’m approaching idle RPMs, I better press the clutch now”.
Stop running over children. Full brake and clutch right after (not even needed). Nobody cares if you stall it. PS: Unless you have no ABS, in which case you need to avoid locking up the tyres.
Sure, brake and then 100 ms later as your RPMs come close to idling levels add the clutch. Which of course is ridiculous as nobody but racing drivers will be able to time that so precisely.
It depends on the speed if at 20 is clutch first, then brake. If at 30 mph or more, its brake first then clutch or can be both at the same time and dont need to worry if the car stalls as the purpose is to stop it.
Nope in an emergency stop, it's brake (hard) following by clutch just after, to bring the car to a quick but controlled stop without a stall. If you engage the clutch first you've lost any engine braking and are freewheeling at that point.
As long as clutch is pushed down before full stop it doesn’t matter, but it’s probably better to focus on brake first and then clutch but doesn’t matter
Why would anyone choose to brake before they clutch? For slowing down normally, for sure use the brake before coasting. But in any hard braking situation, just use the clutch first... You don't want the engine to be damaged or fight you when you stomp the brake pedal. Fun fact: The brakes on German built cars are required to be able to overpower the engine in case of a runaway. But even then. Either clutch at the same time or earlier.
I'm not from this country, I've read a bit in the first phase of driving school (theory, no practical) regarding engine brake of manual vehicles. But during the practical, the instructor taught me that emergency stop you are to press down both. I was confused, I didnt ask (kinda hated that instructor and am also introverted, parents forced me to driving school). First emergency stop I followed his instructions, no issue. Second emergency stop I do what I think shouldve been right/better and brake first, then press on clutch once I feel it's slow enough. I got an earful. Country is Singapore, btw. I'm still confused to this day.
Doesnt really matter. The crucuial part is that you manage to press the clutch down quicker than the brake therefore preventing your car to stall. Many people are taught/prefer to start breaking earlier and press brake first which is fine as well. Just keep in mind that you have to push really hard in order to reach the maximum breaking capacity. Its MUCH harder than you‘d ever expect, so be prepared in an emergency situation.
I always say both if a kid runs out in front of you main thing is stop fast and don’t stall secure car and once obstacle is clear check around safety check and drive off
Depends if ABS is fitted, if so both down at the same time, older cars with no abs used to be brake first followed almost immediately by clutch as you would have engine braking thus stopping quicker.
I personally always do both at the same time but in an emergency I wouldn't be thinking about which one I should be doing first I would just be focused on stopping safely
But stopping safely requires you to break first then clutch down because in the moment you put the clutch down first you actually reduce engine breaking meaning the car would be going slightly faster for that moment leading to a longer distance before coming to a stop.
@@lewis994roche994 like I said I wouldn't be thinking about those kind of things in an emergency I would most likely break first anyway as it's instinct
@@ChubiceOfChunckle20 The brake pads can only slow the car down so much. Engine braking makes it so that you can in theory slow the car down just a little bit quicker. Although let's be honest, the ABS would probably kick in before reaching max load on the tyre gripping on the road
@@Dehydratedpencil any modern car that passes the eu control will have enough brake power to lock the abs without utilizing engine breaking, this exercise is actually pointless nowadays. Still we all do it and are learned to do it that way
You’re not going to get engine braking unless you down shift. You’re actually going to be working against your brakes, but you have less control which clutch in. That’s why it’s brake first.
If it's emergency braking engine braking will have NO EFFECT on the braking distance. I was always taught to press the brake and clutch at the same time (with different force ofc).
If the car have in 1st or second gear ,then clutch first and then break , because in 1st or second gear speed is slow. 3rd or above gears we use first break and then cluth for emergency beark.
"Most ABS systems require the clutch and footbrake to be depressed harshly at the same time to brake in an emergency situation;" From the section on emergency braking in the DT1, sorry folks.
ABS kicks in when the brakes lock up the wheel and prevent it from spinning. When the system recognizes a decrease in wheelspeed thats too high, it will reduce the brake pressure. Try an emergency stop without the clutch, should work anyways - would be pretty dumb if it wouldnt. Imagine you're driving an automatic. no abs in those then, right?
@@ch1kenmeister103 the quoted part is from the DVSA (body setting the standards and the tests) guidance to examiners, it is NOT my opinion. So my answer to the original question posed will be the same, follow the instructions from the DVSA.
I never understood why you have to check your blind spot, like you just drove by this area 1 second ago, you know what's there, and then you will drive off forward only. What would you be checking for?
at higher rpm's break then clutch a bit later if u have the time for it. if not just let it stall. stopping asap is the point. She was going pretty slow so just breaking would get the car to jerk delaying the actual stop. i think in this case both was right. Hard to know for sure just on video
Brake slowly then clutch all in then when your ready slowly take your foot off the clutch slowly, then your ready to continue driving! Hope this helps😊❤
If there is an emergency, both at the same time! In this situation, with a dry road surface and at low speed, it doesn't matter which pedal, etc. If there is "time" to think and calculate, then brake first. On the highway, if the road surface is slippery and the speed is high, of course brake first and then the clutch.
She was going very slow, so she did right by pressing both pedals as she would stall. Rookie mistake was that she didn’t check the weather forecast before accelerating so that the traction control wouldn’t engage.
Almost always Break first especially if the speed is high, at low speed both are ok too. The engine makes a noise if at low speed a full break is used.
Break then at the last moment use the clutch so the car doesn’t stall, you want to hear the car grinding. It does damage the car however you do know that you have done it correctly because the car won’t travel as far.
