My 76 year old father had a dui many years ago that he did not do anything about. He wants his license and did an assessment and said he was low risk. The DMV required him to get an IID installed. He is not in the best of health and is unable to breathe long enough for the device to let him drive. Are there any exemptions he can ask for to help him? He only has social security as income so he cannot afford a lawyer.

IID waivers are rare but sometimes possible, and medical problems are probably the best reason. Proving in court that he cannot blow into an IID breathalyzer, however, might be difficult and would require very detailed testimony from a doctor. Depending upon the prosecutor, there might be a way to get by with a sufficiently detailed letter from the Doctor, but either way, this will be an uphill battle for your Dad, especially if unrepresented. Instead, if his heath is that poor, he might want to start looking at alternate forms of transportation, such as ride sharing services online, which he will probably need regardless as he ages.
