FL H0949

Amends Florida Statute 316.193 to revise penalties for driving under the influence convictions, maintaining existing fine and imprisonment terms for first and second offenses.

Requires mandatory placement of ignition interlock devices for at least 1 year on all vehicles owned or leased by persons convicted of a second DUI offense, at the convicted person's expense.

Authorizes courts to withhold adjudication for first-offense DUI convictions (second degree misdemeanor) when the person voluntarily installs or has court-ordered placement of an ignition interlock device and has no prior withholding of adjudication or other convictions.

Defines "conviction" for DUI purposes as a determination of guilt resulting from a plea or trial, regardless of whether adjudication is withheld or a nolo contendere plea is entered.

Takes effect October 1, 2017.
