Also found in: Dictionary, Thesaurus, Medical, Encyclopedia, Wikipedia.
n. a common neck and/or back injury suffered in automobile accidents (particularly from being hit from the rear) in which the head and/or upper back is snapped back and forth suddenly and violently by the impact. The injury is to the "soft tissues" and sometimes to the vertebrae, does not always evidence itself for a day or two, and can cause pain and disability for periods up to a year. The degree of injury and the pain and suffering from whiplash are often in dispute in claims and lawsuits for damages due to negligent driving.
