- This animation depicts the sequence of events during a multivehicle collision that occurred in Phoenix, Arizona on June 9, 2021, at 10:07 pm mountain standard time.
The animation begins with an overall map showing the location of Phoenix in Arizona, overlayed with an image of a Freightliner Cascadia truck tractor in combination with a Walker stainless tank trailer, like the combination vehicle involved in the crash. Next, a regional map of Phoenix shows the traveling route of the truck transporting milk from Stotz Dairy on the west side of Phoenix to the United Dairymen of Arizona cooperative plant on the east side of Phoenix. The crash location on State Route 202 is also indicated.
A map at higher magnification shows the crash location and the locations of two overhead dynamic message signs. Photographs of the two dynamic message signs are shown, along with the message that was displayed on both signs at the time of the crash: “LAW ENFORCEMENT AT PRIEST EXPECT TO STOP,” which alternated with dynamic travel times. The first message sign is located about 3 miles west of the collision location, and the second message sign is about 330 feet east of the collision location. The location of Priest Drive is also shown on the map.
A map at higher magnification shows the local geometry of the roads near the crash location on State Route 202, which was just east of Exit 4 to 52nd Street. The map is replaced with an overhead photograph of the eastbound 5 travel lanes, with the right lane where the collision occurred highlighted.
Forward-facing Lytx DriveCam video shows the truck-tractor passing the 52nd Street exit, approaching visible red brake lights of slowing and stopped traffic ahead that
had formed a queue in the right lane. The video is stopped just before the truck collides with the end car in the queue.
The collision sequence of the vehicles involved is described using three-dimensional vehicle models. The first graphic shows eight vehicles in the right lane in order: the Freightliner Cascadia truck tractor in combination with a Walker stainless tank trailer; a gray Ford; a black Toyota; a gray Chevrolet SUV; a red Nissan; a white Dodge; a black Mercedes, and a white Lexus. Each passenger vehicle is circled and labeled as they are listed.
A series of stop-motion graphics then illustrate the sequence of the collision, but the illustration is not an exact reconstruction. Also, the graphics do not attempt to replicate the weather or lighting conditions at the time of the crash. The view is generally from the right rear of the truck. The collision sequence is followed by an image showing the final rest of all 8 vehicles involved. As a result of the crash, 4 persons were fatally injured, and 11 persons were transported to the hospital; the truck driver was not injured.
Two photographs illustrate the condition of the vehicles on the morning after the collision. The first photograph is a view looking westbound, with the Chevrolet and truck tractor in the foreground and the Nissan, Ford, Toyota, Mercedes, Dodge and Lexus visible in the background. The second photograph is a view looking eastbound, with the Lexus, Dodge, Mercedes, Ford and Toyota in the foreground and the truck tractor and Chevrolet in the background.
first time ive seen all vehicles accurately depicted in an animation, nice to see for once
killer picture
@@Bket666 thank you bro
Interesting cross section of vehicles. Had it been where I live it would be 7 Ford f150s haha
All that devastation probably only took 2-3 seconds.
More like 10 to 15 seconds after the truck finally came to a stop 100 yards down the freeway.
@@golfandhike5598devastation. "Truck driver was not injured" I believe they are talking about the first bit of contact.
Am I the only one amazed by it being 8 different vehicle makes?
Oh no. I took notice too. 😂
No
Must be.
An odd circumstance; convenient for the makers of this video.
If it were new jersey / eastern Pennsylvania half would be German , two Asian, one American car and one good old American coal roller .
I use my 4 way/hazard flashers when in the back of a que like this. Rethinking how I typically turn them off when 1 or 2 vehicles is stopped behind me. Never thought how far a loaded big rig would push into the que.
Did you know that it is illegal in Florida to use your hazard flashers while your vehicle is in motion?
@@jstrahan2 it's also illegal to be crashed into by a semi truck. I think I know which I rather do
@@christopherredhead4182: This quote is from a Florida State Trooper: "“For as long as I can remember, I have preached not to use hazard lights while driving as it’s raining because it indicates to other drivers something is wrong with you or your car,” he answered. “Well, last year, Florida lawmakers decided to change the law to allow such behavior.”
Simply put, yes, Florida law now allows a driver in severe weather to activate their hazard lights.
Florida statute 316.2397(7) says, “Flashing lights are prohibited on vehicles except: (c) During periods of extremely low visibility on roadways with a posted speed limit of 55 miles per hour or higher.”
“I can almost guarantee you these lawmakers have never enforced traffic laws or investigated anything on our roadways,” Trooper Steve said. “When you activate your hazard lights, you indicate to other drivers that something is wrong, possibly creating a dangerous situation. If you feel obligated during a storm to activate your hazard lights, then maybe you should find yourself a parking lot or gas station to ride out the storm.”
Also, from someone else: "They are for stationery road hazards in or adjacent to the roadway. Not for traveling vehicles."
Flash your brake lights instead. They're much brighter, and they also light up that center "cyclops" light. If you have an automatic transmission, hold your car still with the hand brake, which doesn't activate the brake lights, and press the brake pedal repeatedly. That's an effective attention-getter, though it seems this truck driver was incapacitated - asleep or having a seizure or something.
It's a great idea to turn them on and leave them on!!
I’ve driven truck for 32 years. RAISE THE MINIMUM INSURANCE REQUIREMENTS FOR AUTHORITY. THEYVE BEEN TOO LOW FOR TOO LONG. Prosecute for bad hiring practices and lack of training. These types of accidents are completely senseless.
Hiring practices and training aren’t going to do anything about fatigued driving. This crash is an excellent example of why regulations exist. Without rules limiting driving hours, it becomes a race to the bottom of who drive longest with the least amount of sleep
Raising the insurance requirements is a dumb idea and wont improve safety. I’m an owner operator and have two guys working for me. In 2.5 years we’ve had no accidents; I can barely pay the insurnace now; rising the insurnace will put me and most owner ops out of business then y’all be left with only the big mega carrirers
My old man says that a big problem is "CDL mills". In other words, CDLs are basically given out.
@justinpoland1137 it would be interesting to see a comparison of crash rates from owner-operators with 5 drivers or less, medium sized companies, and large companies (cough cough Swift). I'd be willing to bet it's lower for owner-operators since you're focused on your equipment and employees, while the big companies couldn't provide that oversight if they wanted to
@@jed-henrywitkowski6470 that's an ignorant statement without any info on the driver's qualifications. This could have been a very seasoned, experienced driver who fell asleep.
Jeez that must have been terrifying
I would have been ashamed to show my face!!!
These videos are fascinating. Thank you.
That poor damn chevy
That (those) poor Chevrolet occupant(s) 😫
What's even worse is that they were the third vehicle in and would likely not even have seen that coming due to the cars behind them. There was probably no chance of them being able to do anything about their situation.
The milk tanker weights about 130,000 lb.
lol, not even close...full legal gross is about 80,000
@@neckarsulmeunless you have oversized markings AND permits
Yeah, that's for equipment and long loads...milk isn't going to be a permit load@@adventureoflinkmk2
No, it does not.
@@1320fastback how do you know?
Jeez.
Barely anything left of the Ford, makes me feel terrible forthe 2 people who got crushed
I sincerely hope this idiot truck driver is in jail now. He blamed it on fatigue (they ALWAYS put the blame on something/someone else), yet he still decided to get behind the wheel of an 80,000lbs killing machine, and he killed four people with it.
Fatigue was very likely the true cause. How is that now the drivers fault?
Did you even read my comment, genius? Fatigue WAS the cause. He knew he was tired, and STILL chose to get behind the wheel. Would you prefer if that was fault of the four people he killed? You’re not very bright are you? Geez.
@@anb7408 Dude who hurt you? I literally agreed with you.
So I cannot find any information about if the truck driver was held responsible. He needs to be, at the end of the day he caused this. This was reckless disregard for anyone else's safety on the roadways. He should be named, prosecuted, and held accountable for his actions.
The driver was detained by DOT where he went with in 3 hours to do a full blood and alcohol test and his dash camera that was facing in proved he was not on his phone nor being distracted by anything else in the cab of the truck. This is why it is called an "accident".
@@ronnieam33maybe it was highway hypnosis
How do you know he was being reckless? How do you know it was intentional?
@@ronnieam33 So he wasn't charged with anything? This guy should be in jail for a long time for this. If he wasn't distracted it's almost worse because he has no excuse for why he didn't see the stopped traffic.
Just because 4 people died, doesn’t mean “someone needs to be held accountable.” We are too into punitive procedures in this country. Unfortunate: yes, a crime: no.
Shame on the mess driver! So what was the NTSB famous "probable cause" and what are the recommendations to avoid a similar accident to occur?
Was driver texting? Was driver falling asleep? Was driver in regulation regarding his HOS?
Investigators found the driver had less than a six-hour opportunity for sleep the day of the crash and regularly worked 70 - 80 hours per week.
The trucking company, Arizona Milk Transport, operated under an “hours-of-service exemption” that allows unlimited driving hours for certain agricultural commodities within a 150 air-mile radius.
@@xftb-xq3gm I’ve heard of the rule for livestock (which arguably makes sense for living animals that have feed and water needs). That rule makes zero sense for commodities that aren’t alive.
@@andrewahern3730 Spoilable goods, maybe? (Not defending it, just thinking about it.)
"The National Transportation Safety Board determines that the probable cause of the Phoenix, Arizona, multivehicle crash was the truck driver’s failure to respond to the fully conspicuous traffic queue, likely as the result of fatigue. Contributing to the crash was Arizona Milk Transport’s (1) poor oversight of its drivers, (2) lack of fatigue management program, and (3) failure to enforce its own policies, such as those regarding on-duty hours-all a consequence of its inadequate safety culture. Contributing to the severity of injuries to several passenger vehicle occupants was their lack of or improper lap/shoulder belt use."
He blamed it on fatigue. BUT, he previously had an opportunity to get some sleep, and instead chose to drive. I guess making a few extra $$$ means more to him than killing four people.
Unreal!!
wow.. that is crazy
My mouth was dropped throughout the entire animated crash sequence
What about the milk?
It spoiled
You got it. Got milk.
The route 80 and 78 traffic in new jersey and Pennsylvania result in exit ramp backups , especially fall gameday at the penn state exist . The experience truck drivers know to keep a gap
I hate when traffic comes to a stop like that.
There’s the billion dollar question. Why are they sitting in a live lane of traffic? If they’re going to stay stopped, put your four ways on, and be ready to dodge following traffic.
@@jaysmith1408 are... are you blaming the victims?? and not the vehicle that caused the accident?
Well, other truck drivers usually do blame everyone but themselves. Just like the dumbass truck driver that ran into my truck two years. Too bad for him I had a windshield video camera.
If you're gonna have stationary vehicles on a 65mph highway and the only indication are 2 electronic signage boards no wonder that at some point this was gonna happen. Humans make mistakes, your system has be to designed around that fact.
Got almost every major car company.
that's crazy especially when you consider that the milk tanker weighs 370,000 pounds..
Please show your math. You're only 300,000# off
Twenty years in prison, at a MINIMUM is the correct outcome. However, being a trucker, he will get away with literal murder...as usual.
I'm not excusing the truck driver but I've been deceived by how quickly an upcoming stop causes a backlog well ahead of the stop I was warned about. The signage could have been way better.
I also wonder if the Chevy wouldn't have hitched to the trucker if it were a sedan like all the others?
The truck driver was driving down the road and could have clearly seen the lights ans stopped traffic. I am sorry but they do not let blind people drive for a reason. He is at fault completely for the deaths and injuries unless his truck failed to brake or had a stuck throttle. He could have also steered to the left.
Is there a report?..Why no link in the description?
Yes, lots. The crash happened 3 years ago. Just look up the date stamp and you can find articles-galore about it.
Why can't the narration be like on CSB channel(CSB) the videos there are so much better
Sheldon Smith is the king of narration
milk truk just arrive
1. Why not show the rest of the forward facing dash-cam on the truck?
2. Why were the police bringing traffic to a stop at Priest Rd. to begin with?
Never a cop when you need one, but plenty of them to gum up the works when you don’t.
whatever that traffic stop was there for, it greatly contributed to the accident.
1. Probably for the sake of those whose loved ones' died-? What a horrible thing to see in that case.
Let me guess, you are another trucker trying to pass the blame for lacking professionalism. This driver had multiple warnings about the danger ahead, there is video proof they didn't even touch the brakes, but yet you still try and find a way to blame someone else! Disgusting!
Damn, there's nothing recognizable of the Ford.
I Can't Watch This, Reminds Me Of My Parents Crash.
Sorry
Anyone know which car(s) the fatalities were in?
likely the chevy and prius and ford
Two in the Ford Fusion, one in the Chevy Equinox, and one in the Nissan Altima.
@@jonathankleinow2073 amazing the toyota prius driver survived
@@MetroBaltimoreDashcam Guess we can't knock on prius drivers so much any more, ahahahah.
@@jonathankleinow2073 The Ford and the Chevy I can understand, but the Nissan as well and not the Toyota? Wow
The Truck Tractor is called power unit. I never have heard the Truck or Rig or power unit called a truck tractor.
It's technically a "tractor" and "trailer".
I've heard it be called a tractor trailer all my life, but I've never once heard it be called a power unit.
Tomateo tomarto.
Hell, I still find it odd that Yanks call a piddly Ute a truck.
Though round here the actual trucks are much larger so maybe it's just relative.
The mitochondria is the powerhouse of the cell.
I call it a "bobtail". A "rig" is when it is rigged to a trailer. "Ute" is just short for "utility truck".
So why did the truck driver not react? Why did he not hit his brakes? Did he fall asleep at the wheel? Was he on drugs? That part is not explained here. Who just plows into the back of a line of stopped cars at 62 mph??
This portion is solely the accident reconstruction part. If you want everything else, you have to look up the full report, but to get you up to speed it was determined to be driver fatigue caused by him working 70-80 hours a week as per his company's timesheet records (Arizona has special labor law exemptions for the dairy industry which allows them to overwork their staff).
There was one aspect missing: Why was traffic stopped and was it preventable? It's easy to blame a single human, but stopped traffic in a busy road is a time bomb.
This video was just the crash reconstruction portion. Traffic was stopped due to a road closure, and it was preventable because had the driver not been pulling 70-80 hour work weeks they could have been awake and alert enough to see everyone was stopped dead.
Why are the police purposely causing a traffic jam?
Questions raised
Why are they at a standstill in a live lane of traffic without any rear warning
What is use of overhead display, which doesn’t seem to be using MUTCD approved terminology (I read it as there’s a police checkpoint, and be prepared to be pulled in, not disabled vehicles in right lane at milepost wherever it was).
The video very clearly stated the video evidence showed the driver had no reaction to brake lights, what makes you think the hazards would have snapped them out of it and prevented this accident?
Huh? You've never encounter randomly stopped traffic on a highway before? We don't know how long they were stopped there for but probably not long likely never even had a chance to change lanes. If anything maybe the first car is also at fault but how would it be the fault of the people behind him
Were they only stopped in the right lane?
Be prepared to stop means be prepared to stop for any reason, what is wrong with you?
REQUIREMENTS by law checked by INSURANCE: sat tracking recorders/ life to check speeding. To mutch speeding after warnings cancel ensurance.
damn!

how the heck did the trucker survive
the driver sits above a massive damage soaking engine block. The Chevrolet stuck under the front bumper was also soaking up a bunch of damage. If they remained consious after they were initially struck, side swiping the dodge and the center barier probably prevented them from escaping the vehicle on that side. My guess based on the curved track that the truck made prior to impacting the center median was the truck driver attempting to avoid other vehicles despite momentum. Once the trailer disconnected the cab has considerably less stopping power because there is no weight over the driven wheels and also lost the additional drag of the trailer.
oh but how did he survive when the tractor burned@@RowanHawkins
@@penginator89 it's called a door. He opened it and got out.
Did he sustain injuries?@@timothyhh
@@timothyhh how did he open the door if the truck was on fire
It seems the driver never hit the brakes.... unless they failed....could be other reasons..... an absolute tradgedy....rip and prayers for ALL involved.
It's ironic when a Dodge crashes.
I know the driver happen to
tired and texting ill bet
Why is the NTSB involved in a crash between truck and auto? Don't the state police handle that sort of thing?
All commercial vehicle accidents resulting in a death, the NTSB helps with the investigation.
Life in prison
Stupid comment of the day right here
@@andrewahern3730 Maybe not life but deserves at least 20 years. He killed 4 people all because he kept driving while "tired". His company should be held partially accountable for I assume pressuring him to keep working to get things done even though he was tired, but ultimately it was his decision to continue. Those 4 people (along with all the others injured) need justice served for this. Now if he had a medical event that caused it then fair enough it's truly an accident.
Why were the people stopped on the highway?
I see that you have never been on a freeway.
Another distracted viewer 😢
Trucker's son here: "truck tractor" is redundant.
I find it suspicious and somewhat annoying that government agencies possess and show a video for an investigation but then stop the video at some point and then tell you what the rest of the video showed. The whole “take our word for it” is not a stance that has proved trustworthy in history.
Given that there were fatalities, they'd probably be criticized for disrespect to the victims, or for showing "death porn".

Spilt milk. 😭🤬 What kind of stupidity is it to stop traffic on a Hwy ? There should have been one of those road repair spring loaded thucks that could have saved the lifes of people. 🥺😳 Auto pilot said you're on your own. Time to wake up! That's the breaks. Where ? Road check for seat belts. What the f.... ?
Huh? You've never encounter randomly stopped traffic on a highway before? 🤨
An Attenuator truck is what you're thinking of.
I hope no one cried.
Well... Now this takes the saying: "Don't cry over spilled milk!" to a whole new level! By the way... Why were a bunch of vehicles just randomly stopped on the highway? Sounds like the Lexus driver (or whoever was stopped at the front) should also be considered partially at fault for stopping on an interstate highway and impeding traffic flow!
If you watch the first part of the video, they stated that the overhead signs noted law enforcement had stopped traffic for some reason.
They're just showing the vehicles actually involved in the collision. The narrator mentioned that it was a queue of stopped cars, whether because of the police checkpoint, or to get off at an accident, isn't obvious in the truck video.
Stupid Arizona law no wonder the truck crashed, California should have that law here so maybe more lawyers get rich
Car brain will put the blame squarely on the milk truck driver. I think he is 50% at fault. The system (planners, government, automakers, DOT and big oil) takes the other half. Why? Humans make mistakes. Car-centric environments are not forgiving of human error. Car dependency kills 1.5 million sons, daughters, mothers, fathers, grandparents, aunts, uncles, nieces, nephews... It can be you today or tomorrow. Planning towns and cities around cars was, is and forever will be a mistake. Something has to change.
