The rule that accepting a Florida driver's license means agreeing to submit to chemical testing if lawfully arrested for DUI — with consequences for refusing that are now criminal as well as administrative.

The premise is that driving is a privilege extended by the state, and accepting it carries a condition attached: consent to an approved test of breath, and in defined circumstances urine or blood, if lawfully arrested for DUI.

Implied consent isn't self-executing. It attaches after a lawful arrest, and the officer has to inform the person of the specific consequences of refusing before a refusal counts.

Trenton's Law rewrote what those warnings must include. The advisory now has to cover criminal prosecution, not just license suspension — a first refusal being a second-degree misdemeanor and a second or subsequent being a first-degree misdemeanor, in addition to the suspension periods.

That's a meaningful defense issue right now. Agencies had to update their advisory language and their training, and the accuracy of what was actually read in a given case is a fact question with a recorded answer.

The warnings changed recently enough that what was read to you is worth checking. ---
