devlian [24]

Answer: All of them seem to apply.

Explanation:

A., Its important to know if your car that is being collided is a small car or big truck, as they will end up effecting who gets hurt the most.

B., Same thing as A. but with the other vehicle.

C., The velocity matters a lot with a collision, since a slow crash won't have as much damage as a car going fast and hitting someone. Also it won't be as likely to be fatal if the car crashing into you is going slow.

D., This is the only one I'm not too sure on, but it seems like how fast the car can accelerate once collided with would be a big factor on whether it would come to a halt or skid across the road.
