Key Florida DUI Rules

No Adjudication Withheld

Unlike most other criminal charges in Florida, § 316.656 prohibits judges from withholding adjudication on DUI charges. Every guilty finding or plea results in a formal conviction on the defendant's record. This makes DUI one of the harshest charge categories in terms of permanent record impact.

Implied Consent

Under § 316.1932, driving in Florida constitutes implied consent to submit to breath, urine, or blood testing when lawfully arrested for DUI. Refusal results in an automatic 1-year license suspension for a first refusal and 18 months for a second. A second refusal is also a first-degree misdemeanor.

DUI Manslaughter

If a DUI results in death, the charge escalates to DUI Manslaughter under § 316.193(3)(c)3, a second-degree felony carrying up to 15 years in prison and a minimum mandatory sentence of 4 years.

DUI Defense Strategies

Common DUI defense approaches in Florida include challenging the legality of the traffic stop, the administration and accuracy of field sobriety exercises, breathalyzer calibration and maintenance records, the officer's probable cause for arrest, and violations of the defendant's constitutional rights. Given the permanent nature of a DUI conviction in Florida, investing in an experienced DUI defense attorney can be particularly valuable.
