This paper analyses the influence of human factors in the context of accident prevention, paying particular attention to the physical capabilities of the driver in maintaining control over the vehicle at all times. Therefore the biomechanics of the human body are discussed and analysed in relation to the most important functions of the body which are particularly involved in the vehicle's management. The reduced capabilities of the driver is a consequence of stress which is related not only to the time involved but essentially to the environment including also the interface between the driver and the structure of the vehicle, such as the seat and the angle of visibility. Incorrect physiological posture of the driver or inadequacy of the structure, will produce stress or pain with a consequent reduction in capacity to control the vehicle. Obviously this situation will increase the probability of crashes and accidents. The parts of the human body particularly involved are the cervical and lumbar areas. As a conclusion of this paper the real possibilities of the driver to keep the control of the vehicle at a sufficient level can be envisaged.
