That would depend on how many vehicles are involved. If only two vehicles are involved, and they both stop after the crash, then there is one collision
That's not what is meant. There is ALWAYS more than one collision when a car crashes. There are THREE (3) collisions in every crash. The car itself hitting the other car; your body hitting the dash or other part of the car depending on where you're sitting; and finally the collision that is inside the body, your organs and bones hitting against the inside of your body.
3
At least three 1. Car with object 2. Person with car 3. Internal organs with persons body If the car bounced off an object and hit something else that would be more collisions.
There are two collisions in a crash. The first collision is when the vehicle strikes the object and the second when the unrestrained occupants strike the interior of the vehicle.
objects go through deformation an example would be a car crash
One, if you only count the exact second fracture when the crash happens. Multiple, if you count all the collisions directly resulting from a crash. For example from ripped off parts of the vehicle fall on the ground, the person driving hitting the wheel, or the objects inside the car colliding together and falling to ground. One could say "as many collisions in a crash as there are individual moving objects"
Three collisions can occur in one crash between a car and a wall by the car initially colliding with the wall, then rebounding off the wall and colliding again before coming to a final stop against the wall. The initial impact, the rebound, and the final stop are considered three separate collisions within the same crash event.

Most car collisions happen within 1.2 miles (2km) of a persons home.
Safety researchers state there are three collisions in a motor vehicle crash. This would be the vehicle striking an object as the first, the second would be the occupants hitting the interior or exterior of the vehicle, and the third would be the internal organs of the occupants striking the internal structure of the body.
There are many car crash pictures in the Google image library. There are many other sites that show crash pictures but be aware that some of these can be very gory.
rear-end collisions
To many.
