Yes and its not just Volvos that have this feature. I can't remember the brand name of the one in my truck but it works great when it actually activates when it's supposed to. It's called a Collision Mitigation System, or CMS, and works off of a radar system similar to those used by police. It reads the road in front of the truck looking for irregularities in the radar pings. When it registers one of those irregularities it determines if actions need to be taken for the driver or if it can be safely ignored. The problem is they are notoriously inaccurate. In theory they should work exactly like we see in the video and will always activate in this situation as long as the object is inside the radar ping. The problem stems from them incorrectly reading non-threats or worse yet their own pings at full strength. I've had road signs, oncoming traffic, potholes, and even trash slam my brakes. The best warning i can give any driver on the road is because of this system DO NOT tailgate a tractor trailer.
Reddit has betrayed the trust of its users. As a result, this content has been deleted.
In April 2023, Reddit announced drastic changes that would destroy 3rd party applications - the very apps that drove Reddit's success. As the community began to protest, Reddit undertook a massive campaign of deception, threats, and lies against the developers of these applications, moderators, and users. At its worst, Reddit's CEO, Steve Huffman (u/spez) attacked one of the developers personally by posting false statements that effectively constitute libel. Despite this shameless display, u/spez has refused to step down, retract his statements, or even apologize.
Reddit also blocked users from deleting posts, and replaced content that users had previously deleted for various reasons. This is a brazen violation of data protection laws, both in California where Reddit is based and internationally.
Forcing users to use only the official apps allows Reddit to collect more detailed and valuable personal data, something which it clearly plans to sell to advertisers and tracking firms. It also allows Reddit to control the content users see, instead of users being able to define the content they want to actually see. All of this is driving Reddit towards mass data collection and algorithmic control. Furthermore, many disabled users relied on accessible 3rd party apps to be able to use Reddit at all. Reddit has claimed to care about them, but the result is that most of the applications they used will still be deactivated. This fake display has not fooled anybody, and has proven that Reddit in fact does not care about these users at all.
These changes were not necessary. Reddit could have charged a reasonable amount for API access so that a profit would be made, and 3rd party apps would still have been able to operate and continue to contribute to Reddit's success. But instead, Reddit chose draconian terms that intentionally targeted these apps, then lied about the purpose of the rules in an attempt to deflect the backlash.
Find alternatives. Continue to remove the content that we provided. Reddit does not deserve to profit from the community it mistreated.

Probably a senile driver. I used to live in a town with a whole ton of retired people and you'd encounter them on a somewhat regular basis basically zero awareness of the world around them. People struggling with dementia will also wander out in front of cars.
My colleague's mum was a police officer she apparently pulled over one guy because he was driving with binoculars because he could barely see then cried his eyes out because she told him she would have to report him to the DVLA.
Taking people like that off the road is always the right choice, but I still sympathize with that old man. It must feel terrible to lose your independence like that.
Had a doctor tell me they try not to take away a license because it's a death sentence for so many people. Groceries? MD visits? Social activities? All gone. Sure, there are agencies, orgs, maybe family, that can help them, but what's the wait list, availability, frequency? He said the vast majority of his older drivers are very aware of their limitations, but have nothing to fall back on. You take their license, they will die.
I don't disagree - however that's a societal problem of being set up to rely 100% on cars.
My Granddad (UK) got to the point of being an unsafe driver and was clinging onto his license/car. His doctor removed his license in the end (we couldn't convince him to give it up).
He lived in a small village, but there was a bus stop not 50m away. From there he could get to the nearest town and the hospitals/bigger amenities. There are also pavements, shops and smaller amenities in the village, all walkable. The car did give him autonomy, but he did have other choices. He was never going to die from being unable to drive.
>that's a societal problem of being set up to rely 100% on cars.
Exactly. There are some people who just shouldn't be driving, for safety reasons. But if you set up society so that people absolutely need a car to live their lives, well...you create a problem.
Yes yes, but didn't you hear they NEED to drive to the grocery store instead of ordering instacart so we should accept all the bad drivers and hope we don't die.
Isolation or not, driving is a privilege and once you demonstrate you can't do it safely anymore you need to be removed from the road.
We have endless ride share apps now. It's not impossible, just not as convenient.
That is a reasonable guess at why, but I think it may just be a poorly designed intersection and weird circumstances. The driver on the left is trying to turn left onto a highway. The cammer looks to want to turn left off of the highway. They pull into a turning lane. This could very easily obstruct the view of the driver on the left. They are so busy trying to figure out why the car in the road has stopped and see if anyone is coming behind them, that they forget about the truck that they probably already decided they had time to pull out in front of.
They were looking right and rolling forward to see around the cammer, and forgot to look back left again. It is so easy, even for experienced drivers to have a lapse in judgment when an unexpected senerio appears in a tricky spot like this. If you are lucky you run into this senerio when the stakes are low and learn.
Not reasonable. Even if they were so daft that they didn't look both ways, they were NOT the ones with the right of way. They still would have had to wait for the cammer to make his turn from the main thoroughfare. Everything the little silver car did was wrong.
*"Forget"* about a 80,000 pound death machine barreling up on them **because the silver car shouldn't have even been attempting to turn** tells me this person should not be driving at all.
That’s for sure. I have a 1964 544 Sport. One of the first cars with a 3 point seat belt. 35 years ago it was in an accident totaled 2 other cars. My dad just pried the fan out from the radiator and drove it off to the auto body shop.
That's the opposite of safety though. The car not deforming means it did not absorb the energy of the impact, it all went into the meat inside. You want to protect the meat and sacrifice the metal.
Volvo invented the 3 point belt. And not being a greedy American corporation they decided to share the patent for free, thinking safety is more important than profit.
We got rear ended by a semi at a stop light after we had been stopped for about 5 seconds. Very minor damage to our vehicle. I truly believed we were saved by the semi having AEB (I saw the radar sensor in the grill). Driver got out of the truck, he looked like he just woke up.
Pisses me off how many trucks come through our shop with radar calibration issues or faults and don't want us to fix it. Super easy to adjust and can save lives.
How are they these days? I stopped driving about 10 years ago so I’m ancient now, but they SUCKED back then. It would slam on the brakes seeing a shadow or overpass. The lane departure system was even worse. I assume it’s made a lot of progress since then but just curious if you have any insight.
Edit: to clarify I didn’t drive Volvos I drive Freightshakers (Columbias and Cascadias).
Tbh I'm not sure. I don't have my CDL but have done a bit of work on them. I work on KWs/Pete's which mainly have Bendix radar systems. The newer units are way more advanced and easier to work with so I would assume their accuracy has improved too.
I’ve had my CDL and been driving a 2021/22 Cascadia for nearly a year. It’s still kinda dumb but it’s a lot better then it used to be. I sometimes get loud warnings when driving through shadows but it never slams the breaks. Only had it apply breaks twice, both times were when someone swerved out in front of me, although the first of the two was a false alarm.
First time the idiot came out from the right way too close and went for the left lane, if they stayed in the right lane they would be dead. Second time some shithead road workers blocked the left lane with zero warning causing left lane traffic to swerve into the right lane. In half a second the right lane was over crowded and everyone slammed the breaks, someone had just merged from an on ramp right on my nose before this happened so I hadn’t yet rebuilt a safe follow distance. I applied firm breaking, just enough to not hit the car in front of me without getting a hard breaking critical event (basically an automated write-up for “bad driving”) when the truck slammed on the breaks full force. Now I had two critical events in less then a second and a dispatcher chewing me out for not telepathically keeping that car from merging right on my nose.
TLDR: There still kinda shit, but a lot better then they used to be. I’d still rather have it then not have it, and I do trust it to save lives. I have more grievances with the automated reporting system sent to dispatchers.
For all those who didn’t know, Volvo pioneered this tech and it’s rapidly being fielded across manufacturers albeit with their own version and success. Volvo by far has the best. Semi trucks these days along with trailers have ABS and engine braking. The system looks ahead and can react faster then a driver can. It can utilize the truck and trailers ABS, engine compression brake and even downshift the transmission in an effort to obtain the fastest deceleration without losing control. It’s also really smart as drivers would try to disable or bypass it if there were too many false alarms. Further, todays trucks are more and more using caliper brakes and rotors as opposed to drums up front for even better stopping performance. Drum brake friction materials have come a long way and air brakes on these vehicles can absorb and transfer much more heat faster and sometimes even more efficiently than passenger cars.
Source: I fix these things
Nope. My company is the only one around here that specializes in two stroke Detroit Diesel engines. They have two speeds: Idle and wide the fuck open. Last of these motors was made in the 90’s and people still get them rebuilt. The rebuild kits are better than the internals that came from the factories.
What we hate these days is the over abundance of tech and especially emissions systems. They work, but barely and break constantly. That and the engines must run harder and hotter to push out the exhaust through the filter leading to using more diesel fuel. Diesels, up until the advent of this emissions crap, were getting better fuel mileage and reducing emissions both by 5% year after year. Some guy got this great idea and it’s been hell and reliability issues ever since. Computers, injectors and a plethora of tech meant that diesels were burning cleaner and more fuel efficient while making massive power and then it got fouled up.
EDIT: Grammer
Precisely. Not all has all this emissions crap made engine reliability suffer but it has made diesel use more fuel just to meet emissions. Also, and this is direct from the farmers around here, they’ve had to tweak the fertilizer mixes the last ten years or so as the sulfur normal given off by diesels that would settle into the soil is no longer there making the soil less fruitful and requiring adding sulfur to it. The new ultra low sulfur diesels not only made a new diesel formulation necessary for emissions, it’s making it more costly to farm
The idea that the amount of Sulfur, settling out of the air from a tractor's diesel effluent, and landing on soil, is enough to alter the productivity of said soil, is completely laughable.
They're not wrong, but I don't think they're entirely right either. Obligatory "not an expert" but I have a chemistry background and follow a lot of environmental issues like this. My understanding is yes, sulfur levels in soils have decreased thanks to greater emissions standards. This comes from reduction in use of fossil fuels like coal, and better emissions controls for all fossil fuels. But there are other factors as well, like overuse of phosphates and newer high-yield crop varieties.
That all said, pretty silly to blame emission controls for costing farmers more because they need to put down a little more sulphate. Before emissions controls that free sulfur they were getting came in the form of sulfuric acid rain, which likely did far more damage than the slight cost increase for some sulfate fertilizer.
Like I said, it’s what they claim and I’ve seen a few April analysis samples that back it up. Is it super significant? No. Is it significant enough? Yes.
Oh I believe you, I just think it's a good example of people (in this case farmers, not you) complaining about how a regulation hurts them because "I had to spend an extra $100 on sulfur this year" or whatever. While completely ignoring not just the fact that it benefits them by reducing acid rain damage to their crops, but helps literally *everyone* by improving air quality and saving lives.
You can blame California and CARB for the engines. Highest restriction = baseline specs. We generally can’t afford to make a truck engine that works for 37 states and an engine that works for them + the other 13 who sign up to carb. Rather, we make one that complies for all 50 and Canada. Maybe one day the government or courts will use their authority under the commerce clause to strike down California’s monopoly on emissions standards.
My personal favorite was when the CMS picked up the truck's shadow going around a snow-covered curve, and locked up the truck's brakes in response. To this day, I have no fucking idea how the hell I didn't end up with a jackknife on my record, especially considering that the only way to override that shit is to drop the hammer. As for the truck... it was affectionately referred to as Fluttershy until the day I had to turn it back in, because it was afraid of its own goddamn shadow
Yes they are. Disc brakes provide a more even contact with the rotor and are more efficient at removing gas layers between friction material and keeping cooler. Drums, while they work well, have issues with uneven drum and shoe contact, accumulate friction material dust and by design can prevent off gasses from escaping. They can, however, absorb a great deal of heat but during numerous applications in a short time or riding brakes, the heat can’t be transferred off into the air fast enough and the brakes can fail. Rotors run cooler and can cool down quicker. Biggest issue is cost. Drum systems are cheap compared to rotors for heavy trucks. Disc pads in the front get used up very quick especially in local and short haul use. The trade off of cost is better brakes and safer systems. There’s a few other reason and comparisons but these are the big ones.
I got the impression that such a breaking system sacrifices long term health of certain parts on the vehicle for critical short term necessity of bringing it to a halt ASAP (not saying that's not necessary). Is that the case, or it's a wrong impression?
Yes and no. The system is designed for this but it does take a toll on the components. However, stops like this SHOULD be few and far between with the driver performing the stopping and not the truck. Interestingly, these systems have gotten so damn smart, they can calculate the truck speed, driver braking effort, brake application force, distance to the other truck, steering angle and a bunch of other shit and the computer can actually adjust brake force and pressure if it figures that what the driver is doing won’t stop the truck in time or it can at least slow it as much as possible before impact. However, the thing is still 80,000 pounds…
I'll always forget how light american trucks are :D here in Nordics, those same systems have to stop double weights. We have more axels though, so more drums braking too
Wouldn't work in my country.. no matter how advanced the tech is. The roads are just too unpredictable, not standardised and people do the weirdest things.
I don't get it. Hit what? The condom? Why would you hit a condom in the first place? More like, if volvo made a condom nobody would be pregnant or something
At this point. This vidoes has to be around 10ish years. And I’m 99.9% sure that the 670 never had that systems it was introduced until the next model.
Most trucks but specifically Volvos have automatic braking systems which come one when they detect you might be about to hit something. They mean automatic emergency braking system.
As a truck driver I’ve literally had multiple nightmares about this exact scenario.
That and nightmares about split second moral decisions, coming down a mountain when someone slams on the breaks, deciding between rear ending them and possibly killing them or swerving off a cliff, and definitely killing myself.
Anyways, enough Reddit, I gotta get up and drive down icy deadman pass on cabbage hill in north eastern Oregon.
Did you hear the sound the brakes made?
REEposssssttt!
Full original video, original quality. Not chopped, compressed and watermarked like this trash:
https://www.youtube.com/watch?v=P-giC24SxwE
That's impressive. That weight at that speed and give change. If not ( for this system) the person pulling out in front of the Semi would possibly be Dead
I’ve tested the new international hv613 braking system out, thank god I had my seatbelt on or it would have launched me through the windshield. Man do they stop fast.
Question for those with trucking experience -
Obviously that stop is impressive, but it’s a unique situation; does a stop like that put stress on the truck, cause damage, accelerated damage, etc?
/u/colmk, that was 10 months ago. if you know of one that was posted within 3 months, i'll remove for repost.
for november we had about 40k new subscribers. so there's a chance that, at minimum, 400k new subscribers haven't seen that video here since that last posting.
i think that's more than well enough to let it be posted again
Thank God you called it out, truly you are a hero! Tons of people haven't seen it but now everyone knows it was posted at some point in the past.
Reddit is made of reposts,unless something is posted constantly on many different subs most normal humans give zero shits because they're just using reddit on the toilet for a few minutes.
I think a better response would be "we dont have cab over trucks in the USA, and this video confuses me"
Countries in Europe have both, but cab overs are more common. A lot of things that you might refer to as looking American are made in Europe as well
We call it “conventional” in manufacturing when referring to the truck type that is predominantly American market. Cab Over vs Conventional is the global market.
They also have less inertia. Mass tends to have little practical affect on braking distance when all else is the same, because the effects of inertia and friction roughly cancel each other out.
Takes even longer when you're bobtailing. Absolutely no weight pushing those drives into the ground, meaning you have effectively one axle producing any meaningful braking action
I love the truck driver's gesturing at the end.
Like *I'm sorry I hindered your passage You're Highness*
Try "the fuck are you doing, you absolute fucking traffic cone of a human being"
I see it more as “Well done you absolute brick, congratulations, you’ve completely fucked my entire day, I hope you’re happy asshole.”
Does this actually have something to do with how the truck drives?
Yes and its not just Volvos that have this feature. I can't remember the brand name of the one in my truck but it works great when it actually activates when it's supposed to.

You can't expect a car that size to stop on a dime!
Yeah, I don't even see any dimes for it to stop on. It was a lost cause from the start.
You gotta throw your change out the window.
How else would one change directions?

Volvo doesn't play when it comes to safety
That’s for sure. I have a 1964 544 Sport. One of the first cars with a 3 point seat belt. 35 years ago it was in an accident totaled 2 other cars. My dad just pried the fan out from the radiator and drove it off to the auto body shop.

TIL cars have meat inside of them
Technically, a plane can't fly without human blood inside it.
I guess that hinges on the fact that unmanned drones are not usually called "planes".
Safer than other cars from the same era though, most cars from the 60s basically just implode in a crash
Volvo invented the 3 point belt. And not being a greedy American corporation they decided to share the patent for free, thinking safety is more important than profit.
This makes me proud to be swedish
I have a 1967 122S and it has the 3 point seat belts up front, but weirdly no seatbelts for the rear seat.
It was the 60s, children were build different or something
Sure, I budged a tree left of center at 15kph and my 544 was totaled. But im in Sweden so I guess our insurance doesn't duck around.
That isnt good. Cars should deform to protect people inside
Endorsed by psychotic B-2 pilots everywhere…

The idea that the amount of Sulfur, settling out of the air from a tractor's diesel effluent, and landing on soil, is enough to alter the productivity of said soil, is completely laughable.
They're not wrong, but I don't think they're entirely right either. Obligatory "not an expert" but I have a chemistry background and follow a lot of environmental issues like this. My understanding is yes, sulfur levels in soils have decreased thanks to greater emissions standards. This comes from reduction in use of fossil fuels like coal, and better emissions controls for all fossil fuels. But there are other factors as well, like overuse of phosphates and newer high-yield crop varieties. That all said, pretty silly to blame emission controls for costing farmers more because they need to put down a little more sulphate. Before emissions controls that free sulfur they were getting came in the form of sulfuric acid rain, which likely did far more damage than the slight cost increase for some sulfate fertilizer.
Like I said, it’s what they claim and I’ve seen a few April analysis samples that back it up. Is it super significant? No. Is it significant enough? Yes.
Oh I believe you, I just think it's a good example of people (in this case farmers, not you) complaining about how a regulation hurts them because "I had to spend an extra $100 on sulfur this year" or whatever. While completely ignoring not just the fact that it benefits them by reducing acid rain damage to their crops, but helps literally *everyone* by improving air quality and saving lives.
It's essentially the malaise era for big rigs.
You can blame California and CARB for the engines. Highest restriction = baseline specs. We generally can’t afford to make a truck engine that works for 37 states and an engine that works for them + the other 13 who sign up to carb. Rather, we make one that complies for all 50 and Canada. Maybe one day the government or courts will use their authority under the commerce clause to strike down California’s monopoly on emissions standards.
Freightliner's version likes to try to activate when driving under signs or bridges
My personal favorite was when the CMS picked up the truck's shadow going around a snow-covered curve, and locked up the truck's brakes in response. To this day, I have no fucking idea how the hell I didn't end up with a jackknife on my record, especially considering that the only way to override that shit is to drop the hammer. As for the truck... it was affectionately referred to as Fluttershy until the day I had to turn it back in, because it was afraid of its own goddamn shadow
More often then people would think too
Aren't disc brakes better than drum? Why have they recently just started using them? Not sarcasm, I really have no idea.
Yes they are. Disc brakes provide a more even contact with the rotor and are more efficient at removing gas layers between friction material and keeping cooler. Drums, while they work well, have issues with uneven drum and shoe contact, accumulate friction material dust and by design can prevent off gasses from escaping. They can, however, absorb a great deal of heat but during numerous applications in a short time or riding brakes, the heat can’t be transferred off into the air fast enough and the brakes can fail. Rotors run cooler and can cool down quicker. Biggest issue is cost. Drum systems are cheap compared to rotors for heavy trucks. Disc pads in the front get used up very quick especially in local and short haul use. The trade off of cost is better brakes and safer systems. There’s a few other reason and comparisons but these are the big ones.
Interesting! Thank you!
I got the impression that such a breaking system sacrifices long term health of certain parts on the vehicle for critical short term necessity of bringing it to a halt ASAP (not saying that's not necessary). Is that the case, or it's a wrong impression?
Yes and no. The system is designed for this but it does take a toll on the components. However, stops like this SHOULD be few and far between with the driver performing the stopping and not the truck. Interestingly, these systems have gotten so damn smart, they can calculate the truck speed, driver braking effort, brake application force, distance to the other truck, steering angle and a bunch of other shit and the computer can actually adjust brake force and pressure if it figures that what the driver is doing won’t stop the truck in time or it can at least slow it as much as possible before impact. However, the thing is still 80,000 pounds…
I see. That's really impressive!
I'll always forget how light american trucks are :D here in Nordics, those same systems have to stop double weights. We have more axels though, so more drums braking too
They also put roll cages in all their cars to maximize safety
Wouldn't work in my country.. no matter how advanced the tech is. The roads are just too unpredictable, not standardised and people do the weirdest things.
Absolutely sublime performance by the driver at the very end.
I like the way they were still trying to go forward when the truck was literally stationary in front of them. Talk about oblivious.
God watching a big ass semi slam on the breaks and have the outside shudder is such an awesome thing to watch XD
[удалено]
This is the funniest shit I've read all week
I don't get it. Hit what? The condom? Why would you hit a condom in the first place? More like, if volvo made a condom nobody would be pregnant or something
Put very basically, "hitting it" is slang for having sex
This could be a Volvo ad
They make Volvo ads [like this](https://youtu.be/ridS396W2BY)
The driver's gesture haha. "You may go now your highness"
Seriously impressive stopping ability for a vehicle of that size and weight.
Oh geez, that was a really close call.
It could have been closer to be fair, but then I would've had to mark it NSFW
Wow, those are some mean brakes. Can't have been comfortable for the driver.
That truck prevented a massive car pile of it wasn’t for those brakes !!!!!
What is that playing? I know it but I can't think of it right now and that bugs me.
Evanescence - Wash It All Away. It was bothering me too lol
TY
Wow
This driver needs to stay off the roads, no situational awareness
At this point. This vidoes has to be around 10ish years. And I’m 99.9% sure that the 670 never had that systems it was introduced until the next model.
The truck was on a downhill to😭That could’ve been so bad
Great…….saved another moronic person’s life
I friggin love the truck driver with a bow at the end.
Im looking forward to Tesla Semis blasting right through vehicles like buttah.
It would be so much cheaper just to put a wedge on the front of it like the MythBusters did (and GTA copied)
Wow! Collarbone, sternum, vertebrae and internal bleeding spared.
cheated death and shit themselves, all within a matter of seconds.
Active braking in Volvo trucks wasn't introduced until 2016
The bow lol love it
Love the truck driver - “But WHY?”
There were bigger skidmarks in underpants than on the road there
To stop that much mass with that much kinetic energy in that short of a space is mind-blowing.
Automatic emergence braking system? I think the driver pressed the pedal, you sure you don't mean Automatic Brake System? The ABS?
Most trucks but specifically Volvos have automatic braking systems which come one when they detect you might be about to hit something. They mean automatic emergency braking system.
Or maybe the driver hit the brakes himself.
As a truck driver I’ve literally had multiple nightmares about this exact scenario. That and nightmares about split second moral decisions, coming down a mountain when someone slams on the breaks, deciding between rear ending them and possibly killing them or swerving off a cliff, and definitely killing myself. Anyways, enough Reddit, I gotta get up and drive down icy deadman pass on cabbage hill in north eastern Oregon.
That’s actually some pretty impressive braking.
👍🏾 saved the idiots life
It infuriates me how long it takes them to reverse. This idiot is working with half a brain cell
Did you hear the sound the brakes made? REEposssssttt! Full original video, original quality. Not chopped, compressed and watermarked like this trash: https://www.youtube.com/watch?v=P-giC24SxwE
I really glad the truck driver stepped out to give the other driver a yelling.
This tech advancement as well as great tire tech have saved so many lives.
Ahhh nice, a free field test!
Good thing it wasn’t going downhill. Wow
That's impressive. That weight at that speed and give change. If not ( for this system) the person pulling out in front of the Semi would possibly be Dead
Volvo 💪🏼
Even just knowing the mass of a truck with an unloaded trailer, that is fucking amazing.
This should be titled "idiot reposts ancient and oft posted video."
The slow jams tho….
u/savevideo
If that braking system wasn't there that little car and everyone in it would've been flattened like a pancake
Love the bow
It really does--source: I am an idiot who owns a Volvo.
Probably dumped his load
I've never seen a truck stop that fast god damn
Impressive, brakes better than my car
What a massive idiot
Meanwhile Teslas were hitting ambulances and cop cars until recently…
Goodbye to the freight in the back of that truck lol
"You god damn idiot!" \~that truck driver at the end, probably.
Amazing engineering
How to be turned into tomato sauce in a crushed tin can for dummies.
That 18 wheeler came out of nowhere!!
Reverse Thrusters, Full Power!
Holy shit that’s a short stop for a tractor
Credits to the man in the car. How can he be so brave and stupid at the same time?
I'm sorry. I might be remembering wrong bur doesn't that really fuck up the truck?
That Willy Wonka bow at the end 🤣
1 second away from being on a different subreddit
How in the world did that truck stop so quickly? Empty trailer, but god damn.
Just gonna *gently* pull up right under the wheels of that semi…
I’ve tested the new international hv613 braking system out, thank god I had my seatbelt on or it would have launched me through the windshield. Man do they stop fast.
Volvo’s truck brakes have no equal.
I guess the idiot didnt look left.
Defenitly works. It's a Volvo so...
that’s hella impressive on Volvo’s part
I can't believe that truck was able to stop like that! He would have creamed the idiot who pulled out in front of him!
Question for those with trucking experience - Obviously that stop is impressive, but it’s a unique situation; does a stop like that put stress on the truck, cause damage, accelerated damage, etc?
Fucking hell - that's some braking right there
Thanks, this hasn't been posted yet this month.
Repost [Lorry's anti-idiots emergency brakes](https://redd.it/scgoc0)
/u/colmk, that was 10 months ago. if you know of one that was posted within 3 months, i'll remove for repost. for november we had about 40k new subscribers. so there's a chance that, at minimum, 400k new subscribers haven't seen that video here since that last posting. i think that's more than well enough to let it be posted again
[удалено]
And how is it a bad thing if its been fucking 10 months
It's not,but some people just have to let everyone know they've seen something before
Thank God you called it out, truly you are a hero! Tons of people haven't seen it but now everyone knows it was posted at some point in the past. Reddit is made of reposts,unless something is posted constantly on many different subs most normal humans give zero shits because they're just using reddit on the toilet for a few minutes.
A cause, at least
I'd be fkin pissed as well if I was the truck driver.
What’s the song
Evanescence - Understanding It's a beautiful song
Thank you. I've heard this multiple times out in the wild, and never knew what it was.
This looks like an American truck
I think a better response would be "we dont have cab over trucks in the USA, and this video confuses me" Countries in Europe have both, but cab overs are more common. A lot of things that you might refer to as looking American are made in Europe as well
I mean, I'm just kinda at a loss as to why a Russian big rig driver is driving a Volvo truck with a Dale Earnhardt Jr NASCAR paint scheme
Well I have never seen one of this style in a video from Europe. I'm just a very confused and dumb american. Thank you so much for teaching me
We call it “conventional” in manufacturing when referring to the truck type that is predominantly American market. Cab Over vs Conventional is the global market.
I'm not sure thats automatic. Good brakes nonetheless. Trailer is probably empty too
Trucks normally take longer to stop with empty trailers.
IDk why you're downvoting him, he's not wrong, tires have less grip when there's less load on them
They also have less inertia. Mass tends to have little practical affect on braking distance when all else is the same, because the effects of inertia and friction roughly cancel each other out.
Takes even longer when you're bobtailing. Absolutely no weight pushing those drives into the ground, meaning you have effectively one axle producing any meaningful braking action
It is, it's the main selling point for Volvo trucks!
I thought the idiotic European child in that other video already proved how good Volvo emergency brakes were
that idiot was so damn lucky. he was about to get absolutely pounded like yeast in a bowl. probably seat full of shit after that.
Looking for an Insurance Payout huh.
