Should the tram driver prior to commencing work, make sure that the medicine he is taking has no contraindications to driving vehicles?

The driver of a vehicle, and in particular a professional driver such as a tram driver, is required to exercise due care and not create a hazard in road traffic. Certain medications can impair psychomotor skills to a degree that makes safe driving impossible; therefore, checking their effect on the body is a key element of the responsibility for one's own safety and that of passengers.
