what are the chances of survival for child being hit by a car travelling at 40mph?

Question

regarding public safety tv advert

Answer 1

In reality, not much (around 5%), but it depends how and where it is hit. TV adverts are pretty good at road safety.

Answer 2

40 mph 0-5% survival
35 mph 20% survival
30 mph 80% survival

The 40 mph crash

The injuries sustained by the child after the 40mph crash are as follows:

A fractured pelvis (though this is not visible) and radius and ulna bones (lower arm) along with a skull fracture (base).

Prior to the beginning of the film, the girl, 8 years old (120-130 cms, weighing 55 pounds), ran out into the road, the car (a Ford Fiesta) driving at 40mph in a 30mph speed zone, has hit her at 40mph. She has been hit initially on the pelvis. Her pelvis has broken. Having been hit initially in the pelvis she has been thrown approximately 28m from the car, and has fallen to the ground onto her arm initially, with her head hitting the road next, causing her skull to be fractured (hence the trickle of blood from the ear, and the blood in the hair). She has grazes on the side of her face (on her cheeks and temple) from where she has slid along the road. She has then been placed at the side of the road after being pronounced dead which is where the film begins.

The 30 mph crash

As the commercial goes on, the effects of the 40 crash recede and the body moves into the middle of the road to illustrate the difference in effect between being hit at 40mph versus 30mph. What you actually see are the bones going back into place (the arm), the wound on the head heals itself, and the scrapes recede.

In this scenario the girl, 8 years old (120-130 cms, weighing 55 pounds), has run out into the road, the car (a Ford Fiesta) driving at 30mph in a 30mph speed zone, having not seen her jump out has hit her at 30mph. She has been hit initially on the pelvis. Her pelvis is bruised. Having been hit initially in the pelvis she is thrown approximately 16 metres and falls onto her side, fracturing her arm (though it would not look distorted). She then hits her head, but not so hard as to concuss her. In this scenario she survives, taking a deep breath in as the commercial ends.

Answer 3

You are more likely to kill a pedestrian driving at 40mph than 30mph.
Specifically, if you hit a pedestrian while driving at 20 mph, the pedestrian has a 95% chance of survival.
If you hit an adult pedestrian while driving at 30mph, the survival chance is 80%. But if you hit a pedestrian while driving at 40mph, the pedestrian's chances of dying rises to 90%. (this lowers to 80% for a child).

Answer 4

Not good, I was hit by a BMW doing 28 mph and it knocked me 71 feet, broke my arm, scraped up my body and I was unconscious for 2 days. Luckily I went over the hood instead of under the car. The doctor said I would have died. I am a grown man.

Answer 5

It totally depends on where the kid is hit. Like if he's bending over and the bumper of the car hits him square in the head, or if he's reaching out and the side mirror smacks his right index finger. One has a much higher chance of killing the kid than the other..

Answer 6

At 40 mph, there is a 20% chance of survival.

At 30 mph, this increases to 80%.

Answer 7

If it's an 80% chance of death, I assume it's 20% for living.

Answer 8

20% at 40mph

Answer 9

depending on the mass of the car...

on the normal car mass, almost no chances of survival

if the car is one kilogram, it would be able to move the child one meter every kilogram of the child in one second

a typical car is more than ten kilo. this means more than ten times of the impact above...

Answer 10

20%
