I'm genuinely curious, so I'm sorry if this sounds rude, I just want to know more. Guardrail guy is a guy on KZread that makes videos of him walking around roads and showing every guardrail that's not installed correctly because his daughter was killed by an incorrectly installed guardrail. Is that actually an issue with the guardrails where if every bolt isn't put into the exact place it goes, can it actually kill someone? Because I feel like if that's true, wouldn't DOTs be making sure everyone knew how to install one before letting them go do it for real? Or wouldn't they have made some other regulation to prevent it?

I now pay more attention at the barriers around my city. This is knowledgeable and entertaining. Thank you Andrew!

@@Dragon_breeder all crashes are not accidents and it is often still possible to control the vehicle to a moderate degree during partial loss of control. When I was 19, I hydroplaned on the highway at 70mph in a curve in the rain, the water was too deep because of welling and my tire tread was too thin because I young and broke, I was on a direct collision path with a Grove of trees that would have very likely resulted in my death, so I chose to actively counter steer (a tactic used in rally racing to control the forward direction of the vehicle moving at a high rate of speed on terrain with low traction) and allowed my vehicle to engine brake instead of using my brakes because that would have locked up my wheels and resulted in complete loss of control. I am alive today because of my ability to drive and the choices in made during that crash. Instead of veering off to the right of the road and continuing straight into the trees with only a seatbelt to 'save' me (more like kill me, check vehicle crash stats and impact of seatbelts during collisions over 40mph for context), I guided the vehicle back to the left leaning curve and hit the wire guard rail. Initial impact with the railing ripped my entire left front suspension out of the vehicle, causing my brakes to fail and leaving me with only one wheel to steer and a cable pull hand brake that controlled the rear wheels. I spun out and continued to redirect the vehicle towards the rail to the left side instead of the hill to the right side. I hit all four corners of the vehicle on the rail and did 2.5 full spins, after which point I had slowed down and dissipated enough energy that I managed to straighten out the vehicle even with one wheel and used my handbrake to stop just on the right edge of the road. We're not all old or slow like you I guess. You can work on your reaction times through practice. If the only thing you know how to do in a car is travel in a straight line, you are certainly doomed in the event you lose control. There are advanced driving classes you can take to further expand your ability to mitigate danger in a loss of control event, like sliding on ice or hydroplaning or spinning out, I'd recommend you attend at least one. The only way that you cannot pick where you crash is if you have total loss of traction (rare occurence), your vehicle systems fail due to damage (possible, but unlikely), or you are suffering from a medical emergency. "That's dumb" personal experience and the entire racing industry begs to differ.

I remember in college, in our first actual engineering course, they had us do some problems about this exact topic to drive home how deadly serious engineering can be, and the hard decisions engineers sometimes have to make. If you're making the decision whether to install guardrails, you don't have infinite money. If we want to make calculated informed decisions about where and when to install guardrails, you will eventually need to solve for x, where x is the value of a human life. As much as we'd like to think a human life is infinitely valuable, that would make it impossible to determine when and where to spend on safety improvements instead of, say, improving the roads, providing public libraries, or delivering mail. So there must be a number. Who decides x? Hopefully it's never me.

This video made me feel a little bit safer, thank you. I've always had anxiety in cars from a few accidents I've had, understanding how things work always helps me overcome my fears though

My dad used to work for the state back in the 80’s. He said roadworkers got busted…sometimes, after an accident damaged a guardrail, if the machinery was tied up…the guys would just use older cull post to reattach to guardrail. These post were barely in the ground a few inches and were basically just cosmetic.

This was so cool. My dad was an engineer working on crash barriers in the 80's and 90's, and I went to a few crash tests as a kid. Unfortunately he passed away in the late 90's, so I never got to see his work as an adult, but then when you showed the first collapsible barrier I went "Hey, that's Dad's company's logo!" He's got several patents from '86-'98 on things like changing from the rigid guardrail ends to collapsible ends, as well as the crash barrels you showed. It was really cool to see the kinds of things he was instrumental in changing!

I'm suddenly remembering something I think I learned in driver ed circa 1983, to the effect of guard rails are deadly. They're there to protect the road and other traffic from the crash, not the people in the crashed vehicle. I hadn't explicitly thought about that since high school, but I shouldn't be surprised to learn that engineers have worked on them and gotten better and better over the course of time.

That's kinda funny although it shouldn't:(

A well engineered guardrail saved my life when I got into a crash last year. Long story short I spun out briefly and slammed into the guardrail at 65-55mph and the airbags were broken on my old 2003 Taurus. I strongly believe the only reason I got through with legit just a few bruises and a very minor concussion+very very mild whiplash was a combo between my heavier car, the fact I didn't tense up, the modern guardrail, my properly adjusted headrest, and a newer seatbelt designed to slow you down slightly slower

Thank you for making this video. Guardrails are one of those things that I drive by everyday and, see the changes and often wonder how exactly do they work. I drove a wrecker for about 5 years in the mid-2000s, saw a lot of accidents with injuries due to the older guardrails. I saw how those work first hand while trying to get vehicles off of them and just wondered how this newer technology works. Thank you

Since its your intro and thus a chance to learn -- I REALLY wanted to read the deaths per (something) per year but could not make it out. Deaths per million people, so 25,000 deaths in 1920? Or deaths per million cars? The new MASH guardrails image had type that was worse. Finally (I'm going to stop complaining after this one and just watch) the next was "...this compares two studies ..." which was ENTIRELY illegible. Why bother? Why frustrate us? One of my petty persistent complaint with YT is that the text is often too small to read ... unless I lean forward and peer, or pull the screen closer. I'm not even counting the number of times I've tried enlarging the screen. I tried googling: type script size per screen size but I didn't understand the results. Maybe you will. If you must use small print maybe you should read it aloud as well. "This chart show ..." Thanks for a good video. Oh. Recently a woman was subject to a PIT maneuver and her car rolled over. www.khou.com/article/news/nation-world/pregnant-woman-car-flipped-pit-maneuver-arkansas/91-0f48c495-f124-44bb-af4e-437014f5a97f The police officer who had his lights on was trying to pull her over for speeding. She slowed and put her hazards lights on, looking for a safe place to pull over. He wasn't happy and used a PIT. The road was under construction and had barriers on both sides, I think they were what you call "F" shapes. The officer thought she should have stopped anyhow. Maybe there should be signs up saying "No room for shoulder stop." to make it clear to everyone. Now she's suing the officer and the force. Oh, and Arkansas police killed 3 people this year so far using PIT.

YES! Please do more of this type of content. Dash cam reviews are a dime a dozen. THIS is interesting! In the 70s, I and my childhood friends were traveling with my dad on his work runs. We were in the bed of a camper shelled truck, when we were forced into a steel pole by another driver. The truck centered on the pole at the front bumper at about 30mph. Note, this is before seatbelt usage. Kids in the back were slammed into the back of the cab and the driver was propelled into the steering wheel. No major injuries. Why? We had hit one of the newly installed break-away poles that absorbed the impact and still kept us from careening over the overpass into freeway traffic. Roadway engineers are the silent protectors of us all!

I lived in Barcelona, Spain for 10 years and remember a public outcry to add a second guardrail under the upper one. There are a lot more motorcycles and scooters used on European roads than there are here. Motorcyclists were being killed by striking the posts, at an alarming rate. The government listened and installed a lower rail that undoubtedly has saved many lives. As a rider,I was happy to see the change.

I love how much engineering and research goes into these safety instruments. I assumed that highway barriers were there to protect against head-on collisions from accidental lane divergence. I didn't realize how much engineering went into the shape of the barrier in order to help dissipate impact forces, and kinetic energy; and to help contain rollovers, and vertical movement.

As an Ironworker working on barrier rail on the interstate for miles at a time. A lot of work goes into keeping people safer on the road. It takes over 2 days just to put in the rebar to get a 150 ft stretch that traffic blows past in 1.2 seconds.Then it has to be formed and poured and stripped and polished… construction takes forever..

Love how people are constantly innovating to save lives. As a side note, people often get upset when people in government say some life saving measures aren't cost effective but money is a finite resource and putting a bunch of it to protect against less likely hazards inevitably means stripping it from protecting against more likely hazards. It sounds callous but if your job is to save everyone you can with the budget you're alloted then you have to make sacrifices to get the most safety for your dollar.

what a fascinating video, thank you for sharing! I find it really interesting how safety is handled for different parts of society. Like in aviation, a single fatal incident can completely transform the industry, whereas with cars it's assumed that people are gonna die, and it's more about reducing fatality than eliminating it. It's too bad so much vehicle safety is focused on the occupants though while pedestrians and cyclists are completely overlooked. A few years ago I was in the passenger side of my friends car on the highway when a drunk guy crashed his suv into us. I thought we were dead but fortunately we made it, maybe due to improved highway safety features, so that's a relief :)
