When an under-21 driver refuses the breath test, the refusal itself carries a penalty, a license suspension longer than a low reading would bring, and it can be used against the driver in court. For a young person, the refusal decision and its aftermath need careful handling. Here is what follows a refusal and how it can be challenged.
| Item | Detail |
|---|---|
| First refusal | 1-year license suspension |
| Second or subsequent refusal | 18-month license suspension |
| How it is triggered | Refusing a lawful breath test after the under-21 implied-consent warning |
| Admissible at trial | The refusal can be used as evidence in any related criminal case |
| The deadline | 10 days to request a review of the suspension |
| Implied consent | Operating a vehicle is deemed consent to testing under Florida law |
The under-21 refusal suspension runs through the zero-tolerance process in section 322.2616, and the implied-consent rules are in sections 316.1932 and 316.1939, Florida Statutes. Procedures and figures last verified June 2026.
The refusal penalty, and why it cuts both ways
A first refusal suspends the license for one year, and a second for 18 months, longer than the six-month suspension a 0.02 reading would bring. The refusal is also admissible at trial as evidence. So refusing avoids producing a specific number, but it trades that for a longer suspension and a fact the state can use. Whether it helped or hurt depends on the specific facts, which is why these cases call for individual review rather than a blanket rule.
How a refusal suspension is fought
Like any administrative suspension, a refusal suspension can be challenged within ten days. The review looks at whether the stop and detention were lawful, whether the implied-consent warning was properly given, and whether the refusal happened as the officer claims. A defective warning or an unlawful stop can invalidate the suspension. And because a refusal does not block a criminal DUI, the criminal side still has to be defended on the impairment evidence, covered in the field sobriety exercises and breath test sections.

Underage refusal questions
What happens if an under-21 driver refuses the breath test?
Refusing a lawful breath test after the implied-consent warning carries a one-year license suspension for a first refusal, and 18 months for a second. The refusal can also be used as evidence in any related criminal case. Like the zero-tolerance suspension, a refusal suspension can be challenged within ten days.
Is refusing the test a good idea for a young driver?
It is rarely a simple choice, and the consequences cut both ways. Refusing avoids producing a specific number, but it triggers a longer suspension than a low reading would and can be used against the driver at trial. Whether refusal helped or hurt depends entirely on the facts, which is why these cases need individual review rather than a rule of thumb.
Can a young driver be forced to test?
In a routine stop the driver chooses whether to submit, with the suspension as the consequence of refusing. But in a crash involving serious injury or death, Florida law allows a forced blood draw. Implied consent treats operating a vehicle as consent to testing, and refusing carries its own penalty.
Can the refusal suspension be fought?
Yes. You have ten days to request a review, and the issues include whether the stop and detention were lawful, whether the implied-consent warning was properly given, and whether the refusal occurred as alleged. A defective warning or an unlawful stop can invalidate the suspension.
Does a refusal still allow a criminal DUI?
Yes. A refusal does not prevent a criminal DUI charge. If the officer alleges impairment, the state can pursue a DUI under section 316.193 using the field sobriety exercises, the driving pattern, and the refusal itself as evidence. The refusal affects the license track and adds to the criminal case rather than replacing it.

This page is general information about Florida law, not legal advice, and it does not create an attorney-client relationship. The under-21 zero-tolerance suspension is governed by section 322.2616, Florida Statutes, and a criminal DUI by section 316.193. Deadlines are short and the rules change, so confirm current requirements with the DHSMV or an attorney. Every case turns on its own facts, and past results do not guarantee a similar outcome.
