If you have a mental or physical condition that may impair your ability to safely operate a motor vehicle, even temporarily, you must provide DMV with a medical statement from your physician/nurse practitioner. Some of these conditions include:
Level of consciousness
Seizures
Vision changes
Impairment of judgment
Loss of motor functions
DMV's Seizure/Blackout Policy, established by our Medical Advisory Board, states that a person must be seizure-free or blackout-free for at least six months to establish medication and regain proper medical control before driving. If a person is currently licensed and DMV is notified that the person has experienced a seizure, loss of consciousness or blackout, DMV will suspend the person's driving privilege for a period of six months from the date of the last episode.
DMV will evaluate the medical information to determine if a driver's license may be issued or restricted.
This is from the dmv's website *** Does this mean, if a friend goes out and gets drunk, having a blackout, that the dmv can suspend his driving privledges or does this only have to be a medical problem...
