- IIHS news release • January 28, 2021
Drivers want to save time, and local transportation agencies want to improve traffic flow, but at what cost? With posted speed limits increasing on roadways around the country, a vehicle’s ability to protect drivers in crashes is in doubt.
Small speed increases can have huge effects on crash outcomes, as shown in new crash tests by the AAA Foundation for Traffic Safety, the Insurance Institute for Highway Safety (IIHS) and Humanetics. The safety organizations conducted crashes at three different impact speeds (40, 50 and 56 mph). They found the slightly higher speeds were enough to increase the driver's risk of severe injury or death.

A. Driver education is non existent here. I’ve held drivers licenses in 3 different states and only 1 even had me drive on the highway during the road test.
B. People already don’t follow the laws in place. It’s normal for the flow of traffic to be 10-15 mph over the posted speed limit, with faster traffic doing 20-25 mph over the limit.
C. There’s little enforcement of the laws already. Say what you will about tickets and fines, but if they’re not being enforced, what’s the point of having the laws.
Spot on 👏🏾
Why educate when the capitalistic system prefers fines? Same with our schools. Same with our prison system. Laws are for poor people. Rich can just pay their way out of trouble.
Yet the US has a 74% higher fatality rate than Germany (per vehicle km).

Autobahn
Because germany has newer cars, newer roads, and most importantly, people actually know how to drive there
Lol germany has only 80 million people... u.s. has 380million
@@philleotardo8623 lol, look up what rate means.
Speed cameras are great…if your goal is to slow down traffic for 1/4 of a mile.
That and they'll be put on the absolutely slowest roads to make sure the state gets all that extra tax revenue.
The UK uses average speed check. Works very well.
@@MMM18092 lol... I'd have thought that the UK would have banned driving for non-commercial drivers already, along with guns, pointed knives, hurtful words, and blasphemy against Islam.
That depends on where you are driving and what you take from it.
Speed cameras should be illegal and are in a lot of states. Theres no way you should be able to ticket a car with an unknown driver. A lot of the time whoever owns the car isn't the driver.
I don't think people realize how easily they could die in an automobile accident.
if you are driving a compact/midsize car you can easily die in a 25-30mph head on collision if you hit an suv or truck. also an old car with no side airbags, you can easily die in a minor t bone crash too. if its an suv hitting you and 3/4ths of vehicles are suvs' now
Safety message: apply brakes, crash at 40 mph, survive.
You know how much road/time you need to go from 95mph to 40mph in a 2016 Ford Explorer?
If you watch dashcam vids all day you understand the braking in time is your best bet! Braking is your best option 99 out of 100 times :)
Please start doing crash test at 50 mph.
Why no one drives at 50mph do it at a more common speed on the highway like 70mph
@@ThatGuy-wz3or That's dumb. Because every vehicle would fail.
@@ThatGuy-wz3or a 70mph head on crash is always fatal. The human deceleration limit is 43-45 miles per hour. and designing a car to crash at those speeds head-on would make them impractical
@@ThatGuy-wz3or IIHS has even said that they only do 40mph because when they look at the higher speed test, auto makers will make the car stiffer, which makes it less safer in lower speed crashes.
Energy=mass * velocity^2
I think people need to be taught how to drive better. I say this for a number of reasons. The first being the fact places with speed minimums rather than limits have half the fatality rate than those who have limits. Another reason is think about how fast rally drivers and racers drive on road courses that are closed off and tracks and such. The fatality rate in golf his higher than a race. The point being if drivers where more skilled and knew more about what they where doing then we would have a significantly lower fatality rate. I've even met street racers who where taught on the track and took it to the roadways who haven't wrecked but once or twice, and some who had never wrecked.
The race cars have a special structure to make them safer don't they?
no, it doesnt undermine roadway safety. it exposes the shortcomings of our driver education system, and the overall design and physical condition of our roadways. they are falling apart and the arent repaired properly to begin with. they do the work as cheaply as possible and they are back within 5 years repairing or rebuilding the same section of road!!!
drive a semi for a while, youll start noticing the trend!
Is there a statistically significant trend of higher fatality rates per total miles driven in states that have increased their interstate highway speed limits to those that have not? Also, what has been the economic impact to the states that have increased the speed limits?
An IIHS study looked at the relationship between speed limits increases and crash rates. During 1993-2017, a 5 mph increase in the maximum state speed limit was associated with an 8 percent increase in fatality rates on interstates and freeways and a 3 percent increase on other roads.
@@iihs-hldi I'll be honest I have a hard time believing that. I say that because statistically areas with speed minimums rather than limits have half the fatality rate of those with limits.
@@dakotajones151 That's because Interstate Highways tend to have minimum speeds, whereas other road types do not. Interstate Highways also have many conflict reduction measures and nearly all feature crash barriers and breakaway sign posts, and of course have no pedestrians or cyclists. All these mean that the roads with minimum speeds are not comparable to roads without minimum speeds.
Self driving vehicles cannot get here soon enough. They currently give a license to anyone with a pulse. # of drivers looking at their phone while driving is astronomical, to say nothing of those under the influence of alcohol, pills, etc.
I was in a almost head on collision about 5 weeks ago some dude getting chased by police ran a stop sign on a blind corner and consequently I slammed into I’m I was going like 57 in a 55 and broke my ankle, safe to say when I start driving again Ima be a lot more cautious,
so why isn't the IIHS raising its test speeds? the front offset should have been 60mph by now.
We aren't raising our frontal test speeds because we don't want to encourage designs that will be too rigid to provide the best protection in the most common types of crashes. The vast majority of injury crashes involve forces similar to or less than those the result from 40 mph barrier tests.
@@iihs-hldi I very much appreciate this foresight. Often ruling ignores the unintended consequences of their actions.
@@iihs-hldi In the future, maybe cars can be designed to have different levels of rigidity at different speeds?
@@iihs-hldi That's why you continue using a certain 40 mph test of your chosing and also have a higher speed test so you make sure that you're protected in low and high speed impacts. For regular everyday driving and also highway driving collisions.
@@iihs-hldi Ok, but why not have the maximum rigidity you can before critical injury at slow-speed accidents occur? I feel like cars can be made even more rigid and (given advanced safety belts and perhaps better "sinking" steering wheels) you could easily survive at 40mph and 54mph? Shouldn't that be the goal if cars are anyways becoming faster and speed limits are increased? Imagine how many lives can be saved if cars are designed for any crash speed up to like 60mph (I understand this is very difficult, but surely car manufacturers must always be forced to maximise their safety whereas currently they just have a relatively easy test to pass)
I'd love to see how a MY2022 car would hold up during a 56mph crash..
Probably better, but g forces probably still kill, because 56 mph is very high g forces and at least today, impossible to absorb. in the future who knows, maybe it can save even at 56 mph.
Before 1974 a lot of roads had no speed limit at all out west
So what about the Autobahn with no speed restrictions?
Germany has a lot more requirements to get a license, making a crash less likely, additionally there are plenty of deadly crashes on the Autobahn, not as bad as the U.S., but they are there.
That’s a single road not a network across the country
Improve safety standards then no one drives 56mph no one follows speed limits 80 is what people drive build safety for that regardless of speed limits
Maybe car makers have been 'designing for the test' for too long. Lives would be saved if a cars cabin could hold up just a little better at speeds around 50mph. Hopefully high speed tests of newer cars are in the future
The reality is going from 40 to 56 mph nearly doubles the crash energy because energy increases as the square of the speed. This also drastically increases acceleration. It may not be possible to build practical, road going cars at prices people can remotely afford with such a requirement.
50 mph shows relatively strong integrity in the structure, though the airbags and seatbelts would probably need tweaking. But 56 mph is too much for the structure to handle.
So you talk about speed limits. My question, what speed do people actually drive?
Of course the insurance wants lower speed limits. The only thing they care about is not paying anything to anyone if possible, and lower speed limits is one cornerstone.
No, they do better if you are dead rather than injured. Costs more in medical bills at the hospital and care after you get home.
Maybe, but a byproduct of that motivation is fewer deaths.
All the things you have mentioned are detection and not preventive. Also most accidents happen close to home. The speed of the accidents on this video do not equal the speed on the highway.
which facility is this
These tests were run at Calspan in Buffalo, NY.
Speed doesn’t kill. Distracted drivers are the main culprit.
Exactly no one's going to be crashing that fast if they're attentive because they'll do everything they can to avoid it but the people on there phone filming instagram reels while cruise at 80 will be the ones under the ground
In Oregon DUI is first then speeding for crashes.
And insufficient training there needs to specifically be a freeway portion to driver training and lane management
This is flawed, in a real head on crash at this speed, the barrier would crumple more, here the red part doesn't crumple, whereas had it been another car, it would've crumpled absorbing some of the energy.
If you crash 2 CRVs head on at 56MPH, there would be less damage compared to the vehicle in this test.
This test is not flawed in any manner. If two identical vehicles were traveling at the same speed and they hit each other in this manner the outcome will be exactly the same because each vehicle would absorb half the energy of the crash with exactly 2x the energy input as this. Thinking one crv would crumple more than the other if both are traveling the same speed is simply naive and ignorant of simple physics that most people learn as a child.
@@djumps2455 No, this barrier didn't deform as much as the CRV did. The deformable part of the barrier only accounts for another car's crumple zones and not actually the cabin etc.
The barrier crushes the same amount at 40mph vs at 56mph, soo...
@@akj2387 Okay, I think I get what your stating in regards to the honeycomb aluminum deformation but I'm sure they have reasoning for it's manner of construction. But irrespective of the honeycomb , if 2 objects with identical mass and and construction travel the same speed towards each other and collide then their terminal velocity will be 100% equal 100% of time. The resulting deformation of material which form the masses which collide will be identical. That deformation will be equal to a singular projectile striking a solid immobile barrier. So two vehicles with the same mass+speed+construction(in regards to crumple zones etc.) will have identical deformation to each other and identical deformation to just one of those vehicles hitting a brick wall for example.
So pretty much both crvs would crumple at an equal amount, so it's possible the crv would have less deformation, but how much less? Also to get technical, the driver and passenger side of a lot of cars protected differently until iihs began testing both sides, at least in the small overlap test. That's when the manufacturers started making sure both sides protect the same.
Lets stop raising a generation of people afraid of driving because they think they will die if they go slightly over the limit and actually raise a generation of skilled defensive drivers that are confident. Experiencing a car in an uncontrolled slide and how to control it should be a part of driver training.
Dang
Now people go 80 mph on the expressway all the time
Farting about the safety then ,,,, DRIVES HOME AS USUALLY 20+ over the speed limit like everyone else
increasing speed limits a huge disappointment to us at triple AAA lmao they don't give a fuck about the safety of people they are an insurance all they give a fuck about is the money its costing them
**look at the Autobahn** speed does NOT kill… bad, and distracted drivers do.
Would it be possible for the U.S. to rebuild its highways, dramatically improve road maintenance, beef up its rules for driving licenses so they’re harder to get and require more training, and implement new laws and better techniques of enforcement? Yes. But in the meantime states may want to rethink the trend of increasing speed limits. The numbers don’t lie: During 1993-2017, a 5 mph increase in the maximum state speed limit was associated with an 8 percent increase in fatality rates on U.S. interstates and freeways and a 3 percent increase on other roads. In total, there were an estimated 37,000 more traffic fatalities during these years than would have been expected if maximum speed limits in 1993 had remained in place. In 2017 alone, there were more than 1,900 additional deaths. For more on that, check out go.iihs.org/speeding-over-25-years.
@@iihs-hldi, what about other factors such as distracted drivers on cellphones, high population of drivers on the road ways, and other things that play into affect. You bring up the number of 1,900 deaths but that’s only a 5% of the total deaths that year. Predictive analysis can be pretty close to correct but there is still a margin of error. What is the margin of error which y’all have figured out currently? I am obviously no expert on roadway safety however I do feel as if there are many other factors that play into this.
Another question I have is, what should the max speed limit be? Should it be what your highest speed test showed, high from that, or lower?
When I have to drive behind some jackass going 5 under the already pathetically slow 35 mph speed limit on a non-residential street (which should be 45)... Do you think that makes me MORE or less likely to pass him in an unsafe manner? 🤔
Sorry... but posting stupidly slow limits isn't helping anyone. The speed limit outside the Pittsburgh airport is 55mph...it's an F'n highway... everyone is going to go 65 or higher.
Sadly, the US infrastructure has become so incredibly subject to politics (local or federal), that nobody wants to pay for resurfacing or fixing the absolutely immense network.
In Germany, you will see roadworks on the autobahn everyday.
@@jasono2139 I get your frustration. It's not just about the number that's on the signs, but also the way the road is designed too. A highway that looks like a highway, and feels like a highway, feels wrong when you have do to 35mph. Same as how a residential street would feel weird to have a speed sign of 60mph posted in there.
When speed limits múst be lowered (either because of safety, policy, etc. Just some outside reason it's inevitable), the road should be redesigned to reflect the speed.
What about autoban
The Autobahn speeds? The CRV will get demolished
@@iamblepg How often is a head-on autobahn crash?
@@randomcrashingfacility31 le speed
Speed alone is not dangerous I think speed limits need to continue to rise but we need to be taught better how to drive in these conditions with how vast our country is we greatly need higher speed limits but we need to be taught better like they do in Germany, UK, Japan, Canada
Speed limits must go down, 80 mph is too high speed.
Speed is not the problem. It's the sudden stop. Groan!
do crash test at 80mph
IIHS isn't a regulatory body, so there's no requirement that vehicles perform well in our tests to be sold. We encourage consumers to use the information from our testing to choose a safe vehicle. This was a brand new crash test in 2014, so many models were performing quite poorly.
@@iihs-hldi damn I didn’t realize you guys were an NGO
@@iihs-hldi and yet your tests encouraged manufacturers to make safer cars. there might be no legal requirement, but every manufacturer still wants to look good by acing your tests. time to raise your test speeds.
At 80mph these cars wouldn't be recognizable and would catch on fire too. Wonder what EV high speed crash test would look like?
Like if people in USA follow speedlimits 🤣
I used to drive frequently drive over 100 mph but after watching these videos I drive very slow now lol

You should advocate for better driver training over everything else. Further, anything that's a fine isn't really a crime. Speeding isn't a crime, it's just a way for the government to siphon money out of your wallet.
they work hard to make sure you get a speed ticket easily
Next up: "Why banning cars altogether is the most effective way to reduce vehicle fatalities."
...then ask IIHS and AAA how excited they are by the news that they're out of a job.
Roads need to be straight as possible.
80mph is a perfect speed for the highway. Vehicles just need to be made to protect us at higher speeds as well as lower speeds.
Great idea. How do you suggest cars be made safer at higher speeds?
@@LivingTheDream77 problem is that puts a lot of force on the occupant as the vehicle will stop much faster.

Just drive under or at the speed limits n car makers need to make their cars safer
Until you are hit by a reckless speeding driver :(
Driving under the speed limit on an interstate can be dangerous since you're more likely to get rear ended
Ayo wtf here in Canada the biggest speed limits are 100km/h (60mph) the states be like 90mph
Most highways are 65 to 70 mph but some of them in the western / Southern states are higher.
Speed is bullshit , education yes , teaching at a young age how to handle a crash to the best of your ability is key.
This video is misleading. Studies have shown that the cause of accidents is not speed, per say, but the difference between speeds of vehicles. By INCREASING speed limits, many states have been able reduce the rate of collisions. This is because by raising speed limits, faster drivers are going less over the posted speed limit, and so the discrepancy between slower drivers and faster drivers is less - causing LESS accidents.
This idea - that speed variation, not speeding, is the real danger - is rooted in research conducted in the 1960s on two-lane rural roads, which found that vehicles traveling much faster or much slower than average were more likely to be involved in crashes (Solomon, 1964). However, that same research found that involvement in severe crashes increased with speed.
The thing is though if someone regularly goes 5 over the speed limit and then they increase the speed limit by 5 that person just going to go 5 over the new limit people will always go over the limit only reason they weren't going 10 over to begin with it's only when we get a ticket if you increase the speed limit people will just drive faster
