[Medicolegal aspects of driving ability and discussion of study methods]

Medicolegal aspects of driving ability primarily concern patients themselves, because they are responsible when driving in traffic while under drug treatment. Pain patients taking analgesic medication prescribed by a doctor do not commit an offence, insofar as they are able to drive. A doctor's main duty consists of informing the patient about the way a given disease or drug intake affects driving ability. Patients have the duty to inform themselves about the drug they are taking and to assess their driving ability each time before they drive a car.
