Abstract
Assessment of medical fitness to drive motor vehicles provided by both psychiatrists and addictologists is often required in connection with substance use or dependence. This is most often the case when medical fitness needs to be certified for the purpose of the reinstatement of a driver's licence after the expiry of a driving ban imposed as a sanction for driving under the influence of addictive substances.
However, it is also very common to assess the medical fitness of drivers who were found ineligible to drive as a result of their being reported by their doctors as entering substance use treatment or on the basis of their prematurely terminating or even successfully completing their treatment. The aim of this case study is to show some problematic aspects of assessing medical fitness to drive in the context of diagnosing substance addiction.
