abstract="One of the aims of most driver screening practices, in addition to a variety of possible diagnostic and rehabilitation activities, is to exclude from the driver population those persons who are not &quot;safe enough&quot; to drive. In order to realise this aim, i.e., to decide whether or not somebody is &quot;safe enough&quot; to drive a car, we must estimate his or her individual risk as driver and compare this risk level with a threshold value.  <p>In the present paper, we claim that estimation of individual driver risk for screening purposes implicitly relies on the following assumptions: (1) there is such a thing as individual driver risk; (2) it can be expressed as one parameter; (3) it can be measured or estimated; and (4) thresholds dividing the driver population into safe and unsafe can be identified. The theoretical and methodological problems presented by these assumptions are critically discussed.</p>  <p></p>",
