Drug testing in sport is always possible, especially in cases of accidents or accidental death of co-drivers and /or spectators. It is the responsibility of the competitors to ensure that any medication taken prior or during the races should be cleared by a doctor or qualified pharmacist. Any condition, which might adversely affect your driving skills, must be notified at least one (1) hour prior to the start of the event to the doctor or the organizers. Willfully withholding any information might have serious legal implications.
