Aaron Carter can finally close the book on his DUI case from 4 years ago in Georgia — and he’s gotta be pretty happy, because he’s walking away without doing a day in jail.

A court clerk from Habersham County … Aaron struck a deal with prosecutors, agreeing to plea no contest to reckless driving for the 2017 stop where he refused to submit to a breathalyzer test. The DUI charge goes away.

We’re told Aaron will be placed on 12 months of probation, while also having to complete 40 hours of community service and take some DUI risk reduction classes … plus, shell out around $1,500 in court fees and fines. AC will also be subjected to a drug and alcohol evaluation, and has to comply with whatever other treatment is seen as appropriate.

Assuming all goes well during his probation, he won’t have to spend any time behind bars — which was technically on the table as a possibility when he got arrested.

You’ll recall … Aaron got pulled over in Habersham while cruising with his then-girlfriend, Madison Parker, but declined to submit to the breathalyzer when cops suspected he was under the influence.

Now, the case is officially over and done with.

So, what’s next for Carter? He previously told he’s eyeing another celeb boxing match after losing his first one to Lamar Odom.

Based on that first fight, he should pray Lamar shows as much mercy as prosecutors did on the DUI case!!!
