Hi and welcome to JA. I am Ray and will be the expert helping you tonight.
He may be able to keep his license.There will be a medical report but syncope is listed as one of the exceptions to suspension.
Not sure if the prior one will factor in here.
Reference from dmv..
Are there any exceptions to the rules?
Iowa law allows for an exception when a
medical report indicates the episode:
• Was a single, nonrecurring episode
with an identified cause and treatment
is not required for the condition.
• Has been identified as syncope.
• Occurs only when the person is asleep.
• Occurred when medications were
withdrawn by a physician, but the
person is episode free when placed
back on medications
He may be able to argue syncope and that it falls under the exceptions here since it was a syncope.But expect them to notify him that there was a report if he blacked out and he can challenge any suspension here and seek to keep his license. He is in a serious way here I would strongly urge him to seek local lawyer to see if he can avoid total suspension for medical condition here.The syncope can be argued as an exception.
I appreciate the chance to help you and him here.
