Rear Ended Car Accident

Long Term outlook on Car Accident Treatment

Risk Factors

To review, we’ve covered two risk factors for getting injured in a rear ended car accident.  One is Awareness of the impending crash.  The other is the amount of G forces produced at 5mph.

Today’s article looks at another important risk factor. The position of the people in the vehicle at the time of the accident.  Studies show that people seated in the front of the car are hurt more often than people sitting in the rear seat.  No explanation is given as to why.

Risk Factor Variation

Having your head looking off to the side instead of looking straight ahead is another risk factor.  When your head is turned, the openings between the bones get smaller.  These openings are where the nerves go through.  This is a position to probable injury.  It’s not hard to understand that in this position you could get hurt, even at low speeds.

Conclusion

Getting hit from the rear position seems to be the worst possible way to crash. There have been over 50 papers published in the last 46 years that Proves the poor outcomes of people injured in rear end car accidents.  This table samples just a few of those papers and shows the percentage of people with who live with chronic injuries.
