Whiplash is one of the most common injuries sustained in a road traffic accident, whether you are driving a car, lorry, van or motorbike. It is caused by the sudden movement of the head forwards, backwards or sideways such as happens when you are in a collision. The sudden jerk on your neck causes it to move beyond its normal range of movement and to such an extent that the ligaments, tendons, and muscles in the neck can be damaged by being over stretched. Whiplash injuries can also occur even if the impact is at a relative slow speed.
