The airbag is perhaps the most popular car safety feature. It is also the most mis-sold and misunderstood (as seen in a recent FIR against a car maker). Here is a thread that I hope will provide more clarity on airbag functioning/effectiveness (1/n)
The word 'pedestrian' has two meanings:
1. A person who travels on foot.
2. Something that is not interesting and can be ignored.
Unfortunately, our road designers decided to go with the latter.

Summer is here. Along with the sweltering heat, summer also increases the likelihood of tyre burst crashes. To solve a problem, we must understand it first.
Here is a short guide on what can be done to prevent tyre bursts and how to handle them. (1)
#Roadsafety
This is the situation at just 7.5% household car penetration.
If our policy makers don't plan for alternatives, expect this situation all year round instead of only during vacations/long weekends.
The blame will be put on the parent/child/biker in such crashes.
But if you look closely, there is another important contributor. Can you guess who/what that is?
Never overtake so close to a truck as truck drivers have large blind spots around their vehicle.
Also, an 'indicator' is just that..an indication to other vehicles. We still need to be careful. An indicator does not give us a right to change lanes at will.
Another pile up coincidently involving a KSRTC bus. Is there a maintenance issue with KSRTC buses? or do KSRTC bus drivers like to tailgate?
Thankfully, the Wagonr driver survived.
The tall body that gives SUVs 'road presence' over other vehicles also makes them highly susceptible to roll over even at moderate speeds.
Remember: NCAP ratings do not apply to rollovers.
Always wear a seat belt no matter how 'tanky' the SUV may feel.
This is not a 'freak accident'.
This is a crash due to gross negligence (IPC 304-II) and should be reported as such.
I request the media and journalists to change their approach to crash reporting. Calling them 'freak accidents' is a disservice to the victims.
@dipakdashTOI
Warning: Disturbing video.
Freak accident caught on camera in UP's Gorakhpur. Three people walking on road were thrown into air after hit by a speeding car. Two victims- Moin Akhtar and Akil Ahmed died on spot. Another injured Tahir is currently batting with life in hospital.
The headrest is perhaps the most misunderstood and misused safety feature in a car. However, it saves us from one of the most common crash injuries.
Here is a thread on how the headrest helps us and how to use it correctly (1/n)
This clip highlights the biggest challenges for Road safety in India:
Lack of driver education combined with poor road design and inadequate enforcement.
Improving road safety will require a multi-pronged approach. Unfortunately, there is no silver bullet.
The downside to overselling safety.
3 adults dead and 3 children injured in the Taigun.
Online videos have led car buyers to believe that 5-star-rated cars are literal tanks.
This urges more risk-taking and crashes.
Even 5-star cars have many limits. Don't test them.
We are soon moving to a point where even pedestrians will have to wear reflective jackets and helmets.
This is what we get when roads are only designed for vehicles.
Another reminder that SUVs are highly susceptible to rollover due to their height, even if they are equipped with an Electronic Stability Control (ESC).
Refrain from sharp/jerky steers.

#CyrusMistry
which highlighted the importance of rear seat belt usage.
Keep this image in mind every time you get in the rear seat of the car.
Has there been any car feature as misused as the sunroof?
At this point,
@MORTHIndia
should consider banning this 'feature'. The risks far outweigh the benefits.
Hydroplaning can occur even at low speeds. Always maintain at least 3mm tread depth.
The bus driver will be blamed, but I believe the car's encroachment in the opposite lane instigated the bus driver's panic braking and steering.
It's good that we have built 120kph speed limit roads.
But these roads also require median crash barriers to protect drivers who lose control at such speeds.

Road: Delhi Mumbai Expressway.

@IndiaToday
Such crashes are more common than we realise. And no car stands no chance when sandwiched between two trucks.
@MORTHIndia
should make AEB mandatory, starting with heavy vehicles.
Until then, be extremely alert if you find yourself between two heavy vehicles.
Improving road safety requires an ecosystem change instead of partial approach.
E.g. We can make all cars 5-star rated but that won't matter much if there is no RTO enforcement against trucks/trailers with illegally built bodies or insufficient underrun protection.
@MORTHIndia
An example of what not to do while approaching a curve.
However, I am surprised with the amount of A pillar and door buckling on the Thar in a moderate speed, narrow overlap head-on crash against a similar mass, but slightly stiffer pickup
@theyawninchihua
@alokkumar6994
I don't see a rear underrun protection device (RUPD) in the truck.
It may not have had the crash, but a well-designed RUPD would have prevented the deaths by stopping the car from going under the truck.
#Monsoon
tip:
It only takes 6-9 inches of deep, flowing water to make a car float. Even less if the water/car speed is high.
Do not cross a patch of still or flowing water that is higher than your car's floor level.
#DelhiFloods
@kumarmanish9
Unfortunately, the role of the road designer/engineer will be ignored completely.
Considering the current status of driver education and rule enforcement in our country, we should be doubling down on safe pedestrian infrastructure. Not ignoring it entirely.
A driver safety tip:
Never grip the steering wheel above the steering control level in modern cars e.g. the 10-2 hand position
This is dangerous as an airbag deployment can send your arms flying into the pillars or into your face.
The 9-3 position is recommended for modern cars.
No number of airbags or strong 'build quality' is going to save you in rollovers.
Only wearing a seat belt can keep you safe.
Unbelted occupants, especially children, can get ejected through the windows and even get crushed under the rolling car.
Has decades of poor/nonexistent pedestrian footpaths habituated us to walk on the road even at places where there is a good footpath available?
@walkingproject
Such overtaking is why 2Ws also require blindspot sensors.
Parents fell down after impact, but the infant (on the tank) kept on going ahead with the bike.
The child miraculously survived but could have been severely injured.

Indians don't have car 'dependency'.
We have car 'aspirations', which is much worse.
This is the situation at <10% car ownership in a country where owning a car is linked to success.
Without a sustainable transportation policy, the situation is going to get even more dire.
@TopDriverIndia
It's none of that. Truck initiated pile ups in ghats are a result of driving in neutral with the engine turned off to save fuel. The vehicle cannot stop in time as engine braking is OFF.
Thoppur, Mumbai Pune Expressway, Ganpati Ghat near Indore are blackspots due to this reason.
Two-wheeler occupants constitute 45% of road traffic deaths in India. The helmet is the most important safety device available to two-wheeler riders. Choosing a helmet requires equal care as one wrong decision may have serious consequences. Here is a guide on choosing a helmet(1)
It's strange that using mobile phones while driving is (rightfully) considered as distracted driving.
But at the same time cars are allowed to have large, more distracting touch screens for all controls.
@sidpatankar
A reminder that NCAP crash tests are lab controlled and do not cover all crash types on the road.
Do not take unnecessary risks thinking that your 5-star car will save you in all crashes.
*Warning: Sensitive content*
Always check your mirrors or use the MSM (Mirror-Signal-Manuever) approach for changing lanes, especially near heavy vehicles as these vehicles have huge blindspots around them.
@RoadsOfMumbai
This road has a dangerously narrow left shoulder for a road with 3 lanes with a 100kph speed limit. I wouldn't be surprised if we see crashes with parked vehicles on the left side.
Everyone was standing in complete darkness. Absolutely no warning was given to approaching vehicles.
The car's driver did try to avoid the crash by braking. An advance warning would have given him more time and would have saved more if not all lives.
#ahmedabadaccident
4 dead, 1 critically injured when a car hit a tree in Erode.
A major factor behind the deaths is the lack of belt use by rear occupants.
A reminder that a 'safe' car is only safe if all occupants are belted.

We may not realise it, but the Indian car buyer has also entered this vehicular arms race.
As incomes rise, expect larger and larger SUVs on Indian roads.
Not ideal for a country with a high number of two wheelers and pedestrians.
@DriveSmart_IN
I think this is a case of sleep/medical issue than stopping distance. The truck is slow enough to stop quickly but kept on going. The police officer probably didn't notice/expect it.
I do agree the police should be careful and not assume that vehicles will stop on seeing them.
An airbag is a passive safety system that provides restraint and cushioning to occupants in a crash. The video below will help you understand what an airbag does and how it works. Airbags are designed to deploy and deflate in a very short duration. (3/n)
Please do not confuse vehicle integrity with plain dumb luck. The driver survived just because he was in a shorter car. The car or airbags did not save him (the car's roof can be seen cut in half just above the driver's seat). He probably would have died in a taller car.
@MORTHIndia

today. The BharatNCAP will provide star ratings to cars based on various parameters.
But there are some crucial details that NCAP ratings may not mention. Here are some points all car buyers must know about NCAP ratings. (1/n)
@DriveSmart_IN
I will rephrase it a bit and say that a poor design exposes your risk-taking.
@NHAI_Official
can't even put the signage correctly anymore. That 'Stop' sign should be for the joining traffic (along with a speed breaker). You can't ask main road traffic to Stop here.
E.g. of how crash tests can differ from real-world crashes.
Cars are stationary in side-impact tests. This is rarely the case on road where the forward momentum can cause cars, especially SUVs, to rollover.
The vehicle may be safe, but unbelted occupants will sustain injuries.
@ShivrattanDhil1
The nature of social media of 'doing one better' will encourage more risks and eventually lead to serious injuries/deaths.
@InstagramComms
and others should take responsibility and consider banning such videos to discourage risk taking.
This week, two lives were lost after they got trapped in a vehicle fire. Rishabh Pant's car also caught fire but he was luckily evacuated in time. A vehicle fire is an ever-present risk. Here is a short thread on safely handling vehicle fires (1)
@volklub
Then I would suggest to save some more and buy a truck.
This is what a Nilgai can do to an SUV.
Both frontal occupants sustained serious injuries here.
5 dead, incl 4 children, in a head-on crash between a school van and school bus.
It's distressing to see school buses/vans/autos overload children and drive rashly during school hours.
I request parents and schools to ensure that your child travels safely.
@NikhilCh_
No street lighting, no hazard lights, no warning of any kind. The SUV driver will be blamed, but poor post-crash scene management contributed more towards the deaths.
Yes, the car driver should be held accountable. But, losing 9 bystanders, 2 of them cops, is simply not acceptable.
Safe post-crash management is important too. Request all city police to follow a similar method to keep their officers and bystanders safe.
#Ahmedabad
#Accident
A result of poor guardrail end treatment.
Guardrail end terminals should be properly protected otherwise the beam can easily pierce any car's body. Luckily no one was seated on the left or back in this crash.
@NHAI_Official
Always use fog lights and low beams during low visibility conditions such as foggy weather.
Also, reduce your speed to ensure you do not over-drive the headlights.
@alokkumar6994
That school bag probably saved the girl from certain death.
But questions should be raised on why school girls had to walk on the road. Hopefully, legal action will be taken against the road developer as well Sir. Section 198A of the MVA has provisions for it.
@DriveSmart_IN
Another life that could have been saved if
@NHAI_Official
did its job of providing median barriers.
IMO mis-selling this NH as an 'Expressway' is one of the biggest blunders made by authorities, as this changed the driver's perception and expectations.
Additional fitments such as bull bars and crash guards may hamper airbag deployment as the sensors may not get the required inputs even in severe collisions.
Please do not use such fitments. (15/n)
Genuinely surprised to see the comments.
Yes, the pedestrian is not crossing straight and turned away.
But never forget that the pedestrian has the highest road priority.
Vehicles should slow down when a pedestrian is crossing, not expect the pedestrian to cross faster.
Airbags can also injure you if you are not properly seated. Here is an X-ray of a person who sustained severe leg and hip injuries as they were sitting with their legs on the dashboard when the airbags deployed. (7/n)
@TopDriverIndia
This is where engineering helps through median crash barriers.
@NHAI_Official
and other road development authorities have ignored median crash barriers for far too long.
A good example of how safe road infrastructure can help in reducing injuries even when humans make mistakes.
Road fatalities will only reduce when Humans-Vehicles-Road Infrastructure work in tandem.
The departure angle is too sharp for sleep. No sign of tyre burst or last moment avoidance either
My guess is a sudden steering failure or sudden physical disability.
What do you think?
@skc2000rpm
@SafetyOverSpeed
A must-read thread for those interested in NCAP ratings.
NCAP rating and its interpretation has become a classic case of why half-knowledge is dangerous.
Influencers or those with a brand bias have run riot with their half knowledge, completely missing the point of an NCAP.
The fascination with "stable bodyshell" gets more mysterious every day. The handful of people skeptical enough to even question this too-good-to-be-true narrative suggests there's more than meets the eye -- but let's stick to evidence for now.
Spot the car in the image below.
An India-specific safety tip:
If stuck in traffic, especially on a downhill, don't stay close behind a heavy vehicle. Otherwise, you risk being crushed if another heavy vehicle behind you loses control.
Another pile up coincidently involving a KSRTC bus. Is there a maintenance issue with KSRTC buses? or do KSRTC bus drivers like to tailgate?
Thankfully, the Wagonr driver survived.
@RoadsOfMumbai
The auto has priority here.
However, I wonder why the 2W just cut straight across the intersection instead of taking a proper right turn. The intersection alignment needs to be checked.
He also seems to only check his left and not the oncoming traffic.
Unpopular opinion:
A skilled driver does not necessarily mean a road-ready driver.
We need more drivers who are over-cautious but know the MSM rule or right of way at turns, rather than ones who can make near-impossible turns but dont know what a double solid lane line means.
@chiragbarjatyaa
@skc2000rpm
@SafetyOverSpeed
That's a good point you raised. Although not a factor for this crash, stray animals on the road cause a lot of conflicts.
I guess nobody wants to address the bull on the road. :)
@3rdEyeDude
@skc2000rpm
@SafetyOverSpeed
Yes. Kid crossing alone is a contributor no doubt. But none of the others contributed directly to the crash, except maybe the parked car. There is one factor which directly contributes or even creates the entire scenario here :).
The ‘SRS’ in airbag stands for ‘Supplemental Restraint System’ i.e. airbag helps out the car’s seat belt (Primary Restraint System) by providing some additional restraint. An airbag is not designed to replace the seat belt and by itself is not an effective restraint device. (4/n)
Please don't drink and drive this New year's Eve.
Not only does alcohol reduce steering control, it takes a driver up to 4 times longer to react when driving under influence.
Tyres have a speed limit or ‘speed rating’ that is denoted using a letter on the tyre. Driving near this speed for longer periods can wear out the tyres. The chart below explains the maximum speed for each rating letter. Maintain a speed of 75% or below the speed rating. (5)
Opinion: All market areas in towns and cities around the country should be declared 'No Vehicle' zones along with barricading.
This will make them safer and improve the overall experience.
Airbags are not soft, fluffy pillows either. An airbag is a controlled explosion that can easily kill you if you are unbelted. There are many cases of airbags causing facial injuries, flail chest, and punctured lungs. The seat belt also saves you from the airbag. (6/n)
Only blaming the driver is not going to prevent recurrence of such crashes. The municipal authority is equally culpable for not providing pedestrian infrastructure, forcing people to walk on the road
@SafetyOverSpeed
@Team_Road_Squad
To conclude, an airbag is an important safety feature but it cannot be relied upon in all crashes.
Don’t get complacent just because your car has 6 airbags or some online video/car sales guy gave you assurances.
The seat belt is still the most reliable car safety feature. (end)
@DriveSmart_IN
It's the other way around. Traffic not slowing down at u-turns (like the biker here) is what leads to crashes.
Also, bottlenecks are due to a high vehicle volume and not due to U-turns. Many cities in MH recently closed down U-turns/median cuts but that didn't lower congestion.
Here is a brief function of each airbag in a 6-airbag system:
1. Frontal airbags: protect occupants from frontal impacts
2. Side-curtain airbags: protect the occupant’s head in near-side impacts.
3. Side-thorax airbags: protect the occupant's abdomen in near-side impacts.
(9/n)
@DoctorAjayita
I am sorry but airbags and vehicular integrity played no role here. Just blind luck due to a low-height car. No car is designed to be 'strong' enough to withstand truck underrides.
Increase the car's height by 10-15 cm and the driver would probably be fatal.
And to those who are calling this jaywalking:
The Rules of the Road 1989, Section 11 clearly states that pedestrians have the highest priority at uncontrolled intersections and vehicles should slow down.
In case you do experience a tyre burst, remember not to panic. A tyre burst by itself will never cause a crash. How we react matters more. Do not brake hard or do any sharp steering corrections. Gradually bring the vehicle to a stop on the roadside using engine braking. (end)
With that said, AIRBAG DEPLOYMENT IS NOT DEPENDENT ON BELT USAGE in modern cars i.e. an airbag will deploy even if the occupant is not belted. Airbag deployment is linked to occupancy sensors in luxury cars, but not to belt usage. (5/n)
Please do not speed up when you see a pothole!
No two potholes are the same. Most potholes are long enough to take out tyres/rims and cause crashes. 'Jumping over' at high speeds can also damage the vehicle suspension.
Always safer to slow down and navigate around a pothole.
There are many different types of airbags, with each type performing a different function.
E.g a 6-airbag system has 2 frontal, 2 side-thorax, and 2 side-curtain airbags.
Some vehicles have knee airbags, central airbags, and even pedestrian airbags. (8/n)
It is quite rare for all 6 airbags to deploy in a crash.
At the most 4 airbags may deploy as some airbag modules are programmed to deploy curtain airbags in certain frontal collisions.
However, the threshold deceleration criteria should be met for deployment. (12/n)
This is because, unlike other safety features such as airbags, ABS, ESC, structural integrity, etc., the seat belt is effective in almost all crash types, and perhaps the only feature that can save us in rollovers. (3/n)
