If on probation for drinking and driving, can a person possess a firearm and why does a probation officer never visit an individual’s home?

Assuming this is the only conviction you have AND its a misdemeanor conviction, this conviction should not prevent you from owning a gun.

Check your probation terms to make sure but it is customary that a person on probation cannot use or possess any firearms or weapons. Usually the PO will visit the house initially to validate the address.

This depends on the terms in the probation order. The probation agents do not usually visit homes of people on probation for misdemeanors.

It depends upon the terms of the probation, and it is not required that the probation officer actually visit the person's residence. For from opinion I would have to have all of the details.

If you are on probation for drinking and driving, you are on what's called summary probation and it is not monitored probation that is why a probation officer does not come and check up on you. Also a DUI conviction is a misdemeanor unless you seriously injure someone while intoxicated than it will be filed as a felony. Since your conviction is a misdemeanor, you can own and posses a firearm. That being said, if you are convicted of a felony and you are on monitored formal probation you CANNOT own a firearm or even ammunition. One last thing if you are convicted of a misdemeanor and charged with Domestic Violence, even though it is misdemeanor you CANNOT own or possess a firearm under this circumstance as well.
