How Most Whiplash Injuries Occur

The single most important type of crash regarding whiplash is from a rear impact.
It is clear that people become injured in rear impact collisions at lower crash speeds than are seen in frontal impact crashes.
One of the reasons is crash awareness.
When a person's vehicle is hit from behind, he or she is not aware usually that a crash is impending.
In a frontal crash, the oncoming vehicle is often seen prior and the person can brace for impact.
Studies have shown that people reporting to be unaware of an impending impact were 15 times more likely to have long duration or permanent symptoms compared to those who had warning.
Because of this and also because of the differences in kinematics between frontal and rear impact collisions, it is not unusual for those being rear ended to sustain injuries while those doing the rear ending are not injured.
The acceleration of the occupant is significantly higher in rear crashes than in frontal crashes at the same crash speeds, so the people in the car being rear ended are more likely to sustain injury.
Does there have to be property damage for whiplash to occur? The answer is a definitive NO.
Does there need to be radiological abnormalities for Whiplash to exist? Once again, the answer is absolutely NO.
Is it possible for the person hitting someone from behind to have no injury and the person being rear ended to sustain significant injury? The answer is YES.
The average speed at which people being rear ended are injured is less than people in front end crashes.
2 people are in the same car and get hit.
One is injured significantly and the other is not.
How is that possible? Factors such as age, bodily position, presence of other disease conditions (like osteoporosis), all can come into play during an auto accident.
Given the right circumstances and factors at play, one passenger may be paralyzed, another unscathed.
