What is the most common injury caused by rear-end crashes?

Whiplash injuries to the neck, back, and spine are by far the most common injuries caused by rear-end crashes. These injuries occur when the head moves forward and snaps back like the cracking of a whip due to the force from the rear-end collision. Whiplash is a serious injury that often requires a long recovery. In more serious cases, spinal injury caused by rear-end crashes can even lead to severe brain damage or paralysis.
