Per statute, you cannot receive a withhold of adjudication on DUI. Was the charge reduced?
A judge cannot withhold adjudication on a DUI charge. It's illegal. Now, if the DUI was reduced to reckless driving, for example, a judge could withhold adjudication of guilt.
A withholding of adjudication simple means that no conviction was imposed for a charge after a plea of guilty or no contest. It's called different things around the country, but in Florida, that's the term.
In the State of Florida, a Judge may not withhold adjudication on a DUI case. If your DUI charge was reduced to a Reckless Driving, then a withhold would keep points from being assessed.
