Under what condition can a driver with diabetes be disqualified?

The condition under which a driver with diabetes can be disqualified is if they are insulin controlled. This is significant because insulin-dependent diabetes can pose various risks while driving. Drivers whose diabetes is managed solely through insulin may experience sudden and unexpected hypoglycemic events, where blood sugar levels fall dangerously low. These episodes can lead to impaired cognitive function, disorientation, and even loss of consciousness, all of which are hazardous while operating a vehicle.

In the context of the other choices, it’s important to consider that simply not reporting episodes or being unregulated does not automatically lead to disqualification if the driver can demonstrate that their condition is stable and has been managed properly. Also, just having more than two episodes might not necessarily disqualify a driver if those episodes are well-documented and managed effectively. Therefore, insulin control indicates a higher level of medical scrutiny is required and can meet disqualification criteria if it compromises safety.
