1.2.3 Blackouts due to medical causes not covered in the standards
If the cause of the blackout is determined to be due to a medical condition not covered in the standards then first principles regarding fitness to drive should be applied (refer to Part A section 2 Principles of assessing fitness to drive). Considerations include the likelihood of recurrence of blackout and the treatability of the condition as well as the nature of the driving task. There should also be an appropriate review period. A more stringent approach should be considered for commercial vehicle drivers.
