what types of physical evidence are found in a head on collision between 2 cars?

Answer 1

1. Braking/or lack of braking skid marks
2. Gouges in the pavement caused by car dipping down from braking and being hit.
3. Distance of debris from resting place of vehicles.
4. In high speed crashes, the speedometer is analysed. Sudden deceleration can cause the arm on the odometer to stay in place, or scrape.(Many cars now have digital readouts however)
5. Distance of the vehicle if pushed back from point of impact.
6. Tire condition
7. Brake condition
8. Headlights, (if they were thought to be needed), can be examined (in a lab) to determine if they were on, even if the glass was broke.
9. Seat belts for stretching. (if extended as if worn)
10. Location of vehicle to determine if evasive action was taken.

Hopes this helps. This was not meant to be all that is found, but is the major things. There are many other factors, but you asked for physical evidence.

Answer 2

Besides the obviously two mangaled cars, other evidence might exist around the scene. Maybe a skid mark where someone tried unsuccessfully to stop or manuveur the car out of harm's way. The way the cars are hit and how much damage is done is important to determine which car was going where and how fast they were traveling. The way debris is spread out could indicate more precisly what happened. Also the presence of alcohol containers, illegal drugs, or drug paraphenalia can help investigators determine a cause of the accident. Weather also might have played a role in this collision. All of these would be important pieces of data for any crash scene investigator to know.

Answer 3

Some evidence I can think of off of the top of my head would include:

Damage done to each vehicle.

Skid marks (showing location and direction, and potentially minimum speed at time breaks were applied).

Damage to anything nearby.

Computer in each car showing the speed and control inputs during the last few seconds before the airbag deployed.

Contents of each vehicle, especially if there were open alcohol containers.

The driver and passengers of each vehicle.

Debris scatter from the accident (demonstrating force of impact).

Answer 4

The most obvious would be evidence of a head on impact, I.E. dents in the body of the car at the front of each car.

Answer 5

2 autos headon at thirteen m/s and inelastic if both are doing that %, might want to be double the speed of one million right into a wall. If their blended % is 13m/s it would want to be an same as a million right into a wall, and assuming the vehicle hitting the wall became also inelastic. the first case might want to be the more effective deadly.

Answer 6

Debris from each vehicle, exact location of impact on each vehicle, final location of vehicles after all motion stops, skid marks, condition of each vehicle, etc...

Answer 7

Two cars with the fronts stoved in.

Answer 8

Two cars with smooshed front ends?

Answer 9

Probably some crushed and mangled bodies.

Answer 10

You're not planning an insurance scam are you?
