A DUI charge does not automatically end a Florida commercial driver’s career, but it does move fast against a much lower bar. CDL holders operate under a 0.04% BAC limit, half the standard 0.08%, and a qualifying conviction or test refusal typically triggers a disqualification period. Your next move matters: request an administrative hearing within the statutory window and talk to a DUI attorney before your temporary permit expires.
TL;DR:
- A CDL holder in Florida faces disqualification periods that escalate rapidly, especially for repeat offenses or when transporting hazardous materials.
- Refusing a breath or blood test results in immediate administrative suspension, which can grow longer with multiple refusals, complicating license reinstatement.
- Reinstating a commercial license after a DUI typically requires completing court sanctions, substance abuse evaluations, and paying fees, not just waiting out the disqualification.
- Administrative and criminal cases run on separate timelines, making early legal intervention crucial to minimize income loss and license suspension.
- A first DUI causes at least a one-year disqualification, with longer bans if transporting hazardous materials or if it’s a repeat offense.

How Florida Law Treats Alcohol and CDL Holders
Florida holds commercial drivers to a different standard than everyone else on the road. Under Florida Statute 322.62, the legal limit for someone operating a commercial motor vehicle is 0.04% BAC, not the 0.08% that applies to a passenger car driver. That number was not picked at random. Federal regulators and state legislators treat a fully loaded tractor trailer or a bus full of passengers as a fundamentally different risk than a sedan, so the tolerance for impairment drops by half.
The rule goes further than just the limit. Any measurable alcohol in a CDL holder’s system while operating a CMV can trigger a temporary out-of-service order, even below 0.04%. That order is not a formality. Driving a commercial vehicle during that 24-hour window counts as a separate moving violation under Florida law.
This CMV-specific rule does not replace the general DUI statute. It stacks on top of it. A CDL holder arrested for driving under the influence can face charges under both Florida Statute 316.193 (the general DUI law) and the CDL-specific provisions in Chapter 322. That means a single arrest can produce:
- A criminal DUI case in county court
- A separate administrative disqualification action against the commercial license
- The 24-hour out-of-service order if alcohol was detected during a stop
Do not assume you are in the clear just because you were not over the 0.08% legal limit for regular drivers.*
How Long Does a CDL Disqualification Last for DUI?
The disqualification periods are fixed by statute, and they escalate fast for repeat conduct or hazardous cargo. Under Florida Statute 322.61, a first qualifying major offense, DUI included, carries a minimum one-year disqualification from operating a commercial motor vehicle.
The timeline changes sharply if you were hauling hazardous materials at the time. A DUI conviction while transporting a hazmat load raises the disqualification to a longer period. Federal rules under 49 C.F.R. § 383.51 mirror this same 1-year/3-year structure, so Florida is not an outlier here; it is following the federal backbone that most states adopt for CDL discipline.
Repeat offenders face the harshest outcome:
- First major offense (DUI, refusal, leaving the scene of an accident): 1-year disqualification
- Major offense while transporting hazardous materials: 3-year disqualification
- Second major offense on your driving record: potential lifetime disqualification
Keep the two tracks separate in your head. The disqualification is an administrative action against your commercial driving privilege, decided by the Florida Highway Safety and Motor Vehicles department. The criminal case, with its fines, probation, or jail time for a first-offense conviction, runs through the court system. Losing one does not automatically decide the other, but a criminal conviction is usually what triggers the administrative disqualification in the first place.
What Happens If You Refuse a Breath or Blood Test?
Florida operates under implied consent, meaning any driver lawfully arrested for DUI has already agreed, by holding a license, to submit to a breath, urine, or blood test. Officers are required to explain the consequences of refusal at the time of arrest under Florida Statute 316.1932. Refusing does not make the DUI charge disappear. It adds a separate administrative penalty on top of it, and for a CDL holder, that penalty compounds an already fragile situation.
Here is the sequence that typically follows a refusal:
- Administrative suspension is triggered immediately. A first refusal carries a suspension of a substantial period; a second or subsequent refusal results in a longer suspension.
- A 10-day temporary permit is issued at the time of arrest in many cases, giving you a short window to drive while you sort out next steps, per Florida Statute 322.2615.
- The department has five days to transmit test results or refusal documentation and process the suspension.
- You can request a formal review hearing to challenge the suspension before it becomes permanent.
Refusal can also be introduced as evidence in the criminal case, which surprises a lot of people who assumed refusing meant “nothing to use against me.” It usually means the opposite.
Reinstating Your CDL: The Realistic Roadmap
Getting your commercial license back is rarely automatic, even once a suspension period technically ends. Practitioners who handle these cases regularly point out that reinstatement typically requires completing court-ordered sanctions first, not just waiting out the calendar.
Expect this general sequence:
- Complete a substance abuse evaluation, often through a DUI program approved by the state
- Finish any required treatment based on that evaluation’s recommendations
- File proof of compliance with FLHSMV
- Pay reinstatement fees, which vary depending on the underlying violation
- Retake required testing if your CDL lapsed during the disqualification period
One option a lot of drivers do not realize exists: you can voluntarily downgrade to a Class E license while disqualified, which preserves your ability to drive a regular vehicle even though your commercial privileges are on hold. The catch is that if your CDL actually expires while you are downgraded, you may face additional testing requirements to earn it back once your disqualification period ends.
Pro Tip: Start the substance abuse evaluation the moment you’re charged, not after your case resolves. Reinstatement moves faster when the paperwork trail is already built by the time your disqualification period ends.
If a court also ordered an ignition interlock as a condition of any reinstated driving privilege, getting that paperwork filed correctly the first time avoids a second round of delays.
What Should You Do Immediately After a CDL DUI Arrest?
The first 10 days decide a lot. Florida’s administrative process moves on strict deadlines, and missing one can mean losing the chance to challenge a suspension before it takes effect.
- Comply with the stop, but say little. Provide your license and registration; you are not required to answer questions about how much you had to drink.
- Request a lawyer before answering further questions or agreeing to additional testing beyond what implied consent requires.
- Preserve every piece of paperwork the officer gives you, including the citation and any temporary permit.
- Request an administrative review hearing within the statutory window. Hearing officers under Florida Statute 322.2615 decide these cases on a preponderance standard, and their review is limited to specific procedural and evidentiary questions.
On the defense side, a few angles come up again and again in these cases: whether the officer had legitimate probable cause for the stop, whether the breath or blood testing device was properly calibrated and maintained, chain-of-custody gaps in how a blood sample was handled, and procedural defects in how the administrative suspension notice was issued.
Pro Tip: Fight the administrative suspension and the criminal charge at the same time. A win in one proceeding does not bind the other, and delaying the administrative hearing while you focus on the criminal case can cost you the hearing entirely.
Can You Get a CDL in Florida With a Prior DUI?
A disqualifying offense on your record does not necessarily bar you forever, but it does bar you until the suspension or disqualification period has run its course, or until you have satisfied whatever the court and FLHSMV require. Florida Statute 322.64 ties commercial disqualification directly to an unlawful BAC arrest or a testing refusal, and that status stays attached to your driving record until it is formally cleared.
Before applying:
- Check your status directly with FLHSMV rather than assuming a suspension has lapsed
- Gather proof that any court-ordered evaluation, treatment, or fee payment has been completed
- Confirm whether a prior refusal or conviction triggered a longer disqualification window than you expected
What a Local Defense Practice Prioritizes in These Cases
A CDL DUI case is really two cases running on two clocks: one administrative, one criminal. The firms that handle these well treat the administrative hearing deadline as seriously as the arraignment date, because losing that window by even a day can cost a driver a year of income before the criminal case is even resolved. Coordinating substance abuse evaluations early, rather than after sentencing, is what actually shortens the path back to a working CDL.

FAQ
Can I Get a CDL in Florida With a DUI on My Record?
Yes, but only once any disqualification or suspension tied to that DUI has expired or been resolved. If the DUI led to a one-year disqualification under F.S. 322.61, FLHSMV will not issue or reinstate a CDL until that period ends and any required evaluations are complete.
Is a DUI a Felony in Florida?
A standard first or second DUI is typically charged as a misdemeanor in Florida, not a felony. It becomes a felony under specific circumstances, such as a third DUI within 10 years, a DUI causing serious bodily injury, or a fourth DUI conviction overall.
What Is the 10-Day Rule for DUI in Florida?
The 10-day rule refers to the temporary driving permit issued at arrest under F.S. 322.2615, which lets you drive for a limited window while your case is pending. It also marks the deadline to request a formal review hearing to challenge an administrative suspension before it takes full effect.
What Is the BAC Limit for CDL Holders in Florida?
The legal limit for a CDL holder operating a commercial motor vehicle is 0.04% BAC, compared to 0.08% for a standard driver. Any detectable alcohol can also trigger a separate 24-hour out-of-service order regardless of whether the 0.04% threshold was reached.
Does Refusing a Breath Test Help Avoid a DUI Conviction?
No, refusing typically makes your situation worse, not better. It triggers an automatic administrative suspension under Florida’s implied consent law, one year for a first refusal and 18 months for a second, and the refusal itself can be used as evidence against you in the criminal case.
