Whiplash and whiplash-associated disorders (WAD) represent a range of injuries to the neck caused by or related to a sudden distortion of the neck.

Whiplash is commonly associated with motor vehicle accidents, usually when the vehicle has been hit in the rear; however, the injury can be sustained in many other ways, including falls from bicycles or horses or headbanging. It stands out as one of the main injuries covered by the car insurers.
