You see people walking on the street while looking at their phones.
- They're playing games. - Yes.
It's called Pokemon.
I even saw someone catch a monster...
in the middle of an intersection while crossing.
It's fine if you're playing normally,
but playing while driving on the road...
- is very dangerous. - Yes.
- There is a strange bus in view. - What's wrong?
The bus was being taken away...
- with broken windows. - Was there an accident?
This ski resort bus got into an accident in January.
What could have happened?
The informer had the car pulled over to the shoulder.
- A moment later... - What's going on?
- The bus ran into the barricade... - Why did it run into it?
and fell to its side.
This is the rear camera. After a bus passes,
it's this bus following behind.
Why did that happen? Was the driver sleeping?
(The bus does not slow down and it crashes into the barricade.)
Some people climbed out, and some were clutching their heads.
- Some had bleeding legs. - I'm sure they got hurt badly.
There were 44 of them. That means the bus was almost full.
This accident threatened lives of over 40 people.
We looked into the reason behind it.
The bus driver wasn't paying enough attention.
He thought it would cause a bigger accident with another car.
He tried to dodge to the right and then crashed.
The driver didn't catch the red tail lights of the car in front.
When he finally realized and stepped on the brake,
it was already too late for the car to stop.
Like so.
The driver got distracted for a second.
Thankfully, all of the passengers had seat belts on,
so there weren't any casualties.
A bus should always be more cautious...
as it is responsible for lives of many others.
A moment of distraction can put others in danger.
The peace on this expressway didn't last very long.
There seems to be an accident.
At that moment...
What happened?
While our informer slowed down, another car drives right into it.
It just crashed into it.
While I was stepping on the brake, the other car crashed into me.
The car was damaged badly that it was scraped.
However, the accident didn't end there.
I got out and walked to the back.
Then I could hear more crashes and saw debris flying.
What happened?
(There were multiple crashes happening.)
Multiple crashes were happening.
There were 25 vehicles that were involved.
The expressway was paralyzed.
Why did such a thing happen?
It was icy.
- It was sleeting then. - Was it black ice?
The sleet on this cold day...
ended up making the roads icy.
Even if you're a little late, it's more important...
to arrive safe than to rush on icy roads.
This driver witnessed something shocking while driving.
I saw something I've never seen before.
I was so startled...
that my whole body just froze.
He always drove on this road.
However, it was a little different that day.
There is smoke as if there is a fire.
There are two cars that collided head-on.
There was a lot of smoke, and you could hear the engine.
The way that the car moved,
I assume sudden unintended acceleration.
After crashing into the taxi, the black car continues to make noise.
It ends up pushing the taxi even further.
It's dangerous if it goes that way.
Thankfully it avoided getting into a secondary accident,
but its front wheels continue to roll.
What could have happened?
At that time, one man rescues the unconscious driver.
The car is up in a smoke as it continues to roar.
Could it really be sudden unintended acceleration?
We met with a professional to ask.
The important thing is, the driver is stepping on the brake.
Why? Because the rear wheels are stagnant. It's just the front.
If that's the case, the driver definitely was braking.
It's not the driver's fault. It could be a defected car.
Was there really a defect to the car?
We asked a passenger that was in the car.
The driver has paralysis in the lower body.
He also gets hemodialysis treatment.
We were stopped at a red light.
When the light changed, we still weren't moving.
I told the driver to go, but I could see that...
- he had lost consciousness. - My goodness.
The sudden blood pressure change...
had brought shock to the driver.
(High blood pressure led to a shock.)
If it was a normal car...
where one has to step on the brake,
you can assume the car has a defect by looking at the smoke.
However, if this driver is handicapped...
and was driving with brake mechanisms with hands,
it's likely that the driver is at fault...
instead of the car.
That's right. It looks like the driver lost consciousness...
while having both the brake and the accelerator on.
If you step on both pedals at the same time...
Step on the brake then the accelerator as well.
The front wheels are rolling while making white smoke.
However, the rear wheels do not move...
because of the brake.
(It matches the accident scene.)
You can see that it's exactly the same as the accident car.
A shock can come to a hemodialysis patient at any time.
Do not forget to get enough rest before driving.
(Men in Black Box)
Recently, this driver witnessed something...
- unbelievable. - What is that?
At first, I thought someone was painting the wall.
After I thought about it,
I don't think anyone...
would work alone on Lunar New Year.
Someone is hanging from a building.
- What is that? - The person then suddenly...
slips down the building.
The worried informer decided to report it.
I called 911 first,
- but they couldn't find anyone. - Where did the person go?
The person definitely fell down the building.
There isn't a trace left behind.
The person disappeared.
Then who was the person that was caught...
on our informer's black box?
In order to solve the case, our team went to the building.
Could merchants at this building know about this person?
You can only go in and out through the front door.
This person ran away through another route.
It must be someone that knows the building.
Someone related to the building?
This is the CCTV footage from the building.
You can see dirt falling down from above,
but you cannot see anyone.
Why was this person hanging on the wall?
They could have potentially tried to break into the 2nd or 3rd floor.
Who could it be?
No matter their intention,
hanging on a building is very dangerous.
(Everyone is back home.)
Here is a passenger going home...
late at night on a taxi.
The passenger must be tired. They're not moving at all.
I'm not sure if he was conscious of the camera,
but I thought it was strange he kept his head down.
- I was doubtful. - What is it?
The driver was almost at the destination...
with his tired passenger...
when the car stopped on a red light.
At that moment,
the passenger is fleeing.
The taxi driver is at a loss for words.
It was about eight dollars.
Maybe a little over eight dollars.
I have a son his age.
- I worried for his safety. - He saw him as his son.
He ran away in between cars.
I was worried he might get hurt.
Could he have known how worried the driver was?
The passenger ran away without looking back.
- Don't take a taxi then. - How bitter.
It's not even that late. He should take a bus.
- What is that? - This is an expressway.
- It's a person. - No, it's not.
- It's a person. - It's definitely a person.
At first, I thought it was a stuffed animal.
- Could it be a tollgate staff? - It's like a movie.
The person looked young. Maybe they're in their 20s.
The person could fall if the truck continues to drive.
Of course.
The informer continues to honk to warn the driver.
The driver has no idea and doesn't plan on stopping.
The car drives quickly ahead...
to tell the truck driver about the man behind.
There's a person on the back.
What does the man in the back have to do with the driver?
They didn't know each other at all.
- The person just walked ahead. - What is that?
What if he fell...
- and the car behind had hit him? - I can't understand.
Hanging on a running car...
is like forfeiting your safety.
Do not do something like that.
(Frequent fatal accident site)
The accident happened just over there.
This informer experienced something he will never forget.
When I saw it,
it wasn't even a second.
He was going home late with his colleagues.
What is that?
There wasn't anything on the road before.
- What is it? - It was a man...
on an electric wheelchair.
That was a person?
- Yes, it was a person. - What happened?
The man was on a wheelchair...
- and was just sitting there. - Why did he do that?
- He wasn't moving at all. - He must be disabled.
This was definitely a road...
meant for cars. The informer couldn't have...
imagined seeing an electric wheelchair here.
It was so sudden, he couldn't dodge it.
He was really upset and sad.
He's in the reverse direction.
What will a professional think?
(Automobile incident specialist, Lawyer Han Moon Cheol)
At 70km per hour, you drive 20m in 1 second.
On top of that, there are no streetlights.
If you're at 70km per hour, you'd crash in 2 seconds.
If you see a person out of nowhere...
There is even a flowerbed in the middle.
No one could imagine seeing a person there.
If the electric wheelchair was driving in reverse direction,
we could see the wheelchair at fault for 60 to 70 percent.
Accidents on the road do not come with a warning.
The moment you hold the handle, you should think twice...
and keep to the basics. Then we'll reduce accidents.
There are still some people we're curious about.
That person hanging on the side of the wall. If you're watching,
please explain to us what happened.
A trauma on the road means big accidents.
There are guardrails to avoid such accidents,
but some of these guardrails are useless.
The shocking story behind guardrails.
Trauma will find out.
It's a miracle Ahn Seung Hyun is going back up this road.
The closer he gets to the accident site, his memories rush in.
I still have a hard time, so I don't use this road anymore.
I was traumatized...
- since then. - What could have happened?
- He's still traumatized. - Here.
- Is it here? - Yes.
What could have happened...
- on this road? - It's just a suburban road.
The road was icy after snow.
- The car slipped and fell down. - Is it falling down?
I crawled out after breaking the side window.
Other cars had fallen, too.
The tow truck driver told me that this place...
had many accidents before already.
Were there a lot of accidents here?
The car would fly down from there.
The car fell on that thing.
I don't know how many times.
- It was a lot. - A lot of cars fell?
Something is missing from the driver's black box footage.
They had no choice but to just fall down.
- Nothing is blocking the cars. - No.
There are no guardrails.
Only if we had guardrails then, I wouldn't have got in an accident.
It's unfortunate.
Drivers think that guardrails...
are the best safety measure for driving.
- An SUV fell. - However, the guardrail...
ironically makes accidents even bigger at times.
All drivers are facing risks while driving alongside guardrails.
- What is that? - It fell twice.
A suspicious fire broke out and was captured on CCTV...
at Banpo Road on the 3rd of this month.
- A car went into flames. - What is that?
From what people captured, you can only see the car on fire.
You cannot see the driver anywhere.
- That's true. - Did it fall down?
I'm not sure if the driver got out.
This witness was very close to the accident site that day.
- Hello. - How did it happen?
I heard some explosions. It kept going off,
so we couldn't go up close.
It came straight through here, and it didn't slow down.
After crashing here initially, it fell down over there.
One car was on Banpo Road when it crashed...
over the guardrail and fell down to the road below.
I'm worried about the driver.
As soon as it dropped, the car exploded and a fire started.
- That's what happens. - The driver...
could not escape the car and died in the car's fire.
- That's unfortunate. - Gosh.
This is the car the driver was riding.
Once the white cover was lifted, you can see how horrible...
the accident was from the ashes.
Why wasn't the car stopped from falling?
There was a blockade, but it was too low.
- If the car didn't fall, - Of course not.
- the driver wouldn't have died. - No.
The guardrail couldn't save the driver.
A small crash will end up...
bending or breaking them.
That means it's not doing its job.
I do not think they can protect drivers.
The life...
of the young 31-year-old driver was not protected.
His family believes that his death could have been avoided.
Had there been a proper fence,
he wouldn't have fallen down.
At the least, he would be alive.
There was another unfortunate accident.
A person, a person.
A driver had hit a guardrail.
They drove through a guardrail.
- They came down 60 to 70m. - They came all the way from there?
They flew down.
The accident car is crumpled like paper.
The driver that drove through the guardrail passed away.
Currently the guardrails in Korea...
are not that sturdy.
If a car bounces off a guardrail and goes to the other side,
then it would penetrate through everything.
That's scary.
Guardrails are made in order to avoid secondary accidents.
However, the reality is that guardrails...
can easily be broken down with a small shock.
A bus seems to be reversing...
on an overpass.
Gosh, what just happened? The bus fell down.
What if someone was down there?
The cars parked below were damaged as well.
- It came from the sky. - It's so unexpected.
At the time of its fall, the guardrails didn't help at all.
Just by looking at it,
you can see that the guardrails are too weak...
to stop a 10t bus.
We visited the accident site with a professional.
They just replaced it with the same thing.
This is below standard.
You can see that the repair was poorly done around the joints.
Do you see this empty space?
There is a bolt underneath. Look down here.
- This doesn't have one. - They didn't put it in?
They're all missing.
There are no bolts.
This one is missing, too.
If a car hits this, the shock will split them apart.
This cannot stop a car.
- It just looks like guardrails. - They will just break.
Frankly, these are useless.
Even after the accident, the guardrails were not fixed properly.
The problem is, they fixed it by putting back the broken ones.
They fixed it with the broken guardrails again.
We cannot install it if the height or size don't match.
We have to put in the same ones.
We noticed on the site that all the bolts were missing.
I have to check on that matter. I'll check on that.
These guardrails were installed in 1980s...
before efficiency tests were standardized.
They were put up 30 years ago.
Since they're not safe, they should replace them...
- with ones that have been tested. - They should change them.
Out of all the guardrails in Korea, more than half are dangerous...
and haven't gone through the efficiency test.
What is a proper guardrail?
On an expressway, a car shouldn't bounce off...
when driving at 80km per hour.
On a bridge where fatality rate is higher for a fall,
three-tiered guardrails should be installed...
to absorb the shock.
Curvy roads that have frequent falls require special guardrails.
On highly dangerous roads, rolling barrier guardrails...
should be installed.
- They're very efficient. - Is that rolling barrier guardrail?
- Yes. - That will make things safer.
- On a curvy road prone to falls, - Like that?
- a car crashes into the guardrail. - It just slips.
The damage is minimal to the rails as well as the car.
Usually when a car crashes into the guardrail,
the shock bounces the car back to the road.
You can witness cars getting partial destruction.
You'll be safe even after the crash.
Trucks are heavy and big.
- They can easily topple over. - Of course.
Once they cross over the guardrail, it'll be a huge accident.
Then when a truck runs into it,
will this guardrail still stand?
This experiment also took place where trucks frequent.
There are some broken fragments, but the guardrail did not...
break down and the car didn't fall over.
It doesn't bounce the truck back to the road either.
The remains after the crashes are very different.
If these guardrails were built slowly and sturdy...
while thinking of safety,
they would do their job in stopping cars from falling...
while avoiding tragic accidents.
7 years ago, a truck fell down and 14 people died.
The father who sent off his daughter on the bus...
still lives in a nightmare.
I regret sending her away on that bus.
I feel guilty for not being able to protect my child.
My wife and I are still tortured by it.
Seven years ago and even now,
the safety of the roads have not improved.
They never had crash tests before.
I'm sure many products will not pass the test.
That means we cannot trust the safety of these products.
You can tell just by looking.
You can think of it that way.
It's impossible to replace every guardrail in Korea at once.
- There's the budget, too. - Of course, the budget.
It's been five years since a safety guide...
was announced to make guardrails safer.
For the last five years,
how many steps to safety did we take?
The safety of our drivers should not fall anymore.
Guardrails are the final safety protection.
If they are 30 years old, that's before I was born.
The guardrails being installed now...
have passed the safety tests.
The problem is that more than half were installed before.
You can't exchange safety with money.
- Exactly. - They should...
replace the guardrails very soon.
Men in Black Box will continue to deliver safety information.
- Sundays with Men in Black Box. - Men in Black Box.
We're looking for victims or witnesses that experienced...
or saw harassment while dating in cars.
