Abstract
All drivers, suspected of drug addiction, whose licenses are withdrawn, must undergo medical and psychological investigation before they are allowed to drive again. In our examination of these drug addict drivers over the last 8 years, the means used by individuals to cure their addiction (methadone therapy, psychological therapy, placement in a therapeutic community, self-help) were taken into account. A follow-up study has been conducted of all those examined in 1979, 1980 and 1981. The different data made it possible to consider the role played by the medical-psychological team, whose task was to judge driving ability, in the therapeutic process itself.
