How should you protect a person who, while driving without his safety belts fastened, has suffered an injury to the face and probably of the neck spine, but is conscious?

In case of a suspected cervical spine injury, it is crucial to immobilise the casualty's head to prevent further, irreversible damage to the spinal cord. Any sudden or uncontrolled movement can lead to paralysis or death. Therefore, the safest course of action is the manual stabilisation of the head in the position found, until the arrival of qualified emergency services who have the appropriate equipment.
