You are currently viewing How a DUI Can Affect Your Commercial Driver’s License in Florida

For a commercial driver, a DUI can threaten both driving privileges and the ability to earn a living. A DUI in your personal vehicle can affect your commercial driver’s license, even when you are off duty. Florida’s commercial licensing penalties apply in addition to the consequences of the criminal case.

Drivers in Sarasota, Bradenton, and throughout Florida should understand the difference between a DUI charge, an administrative license action, and a conviction.

Can a DUI in Your Personal Car Affect Your CDL?

Yes. Florida Statutes section 322.61 provides for a one-year commercial driving disqualification when a CDL or commercial learner’s permit holder is convicted of DUI while operating a noncommercial vehicle.

Driving your personal car, being off the clock, or having no connection to your employer does not eliminate this consequence.

How Long Can You Lose Your Commercial Driving Privileges?

The principal conviction-based consequences include:

Circumstances Commercial driving consequence
First qualifying DUI conviction Generally one year of disqualification
Qualifying offense while transporting hazardous materials covered by the statute Three years of disqualification
Two qualifying major offenses arising from separate incidents Permanent disqualification under Florida law

The permanent-disqualification rule is not limited to two DUI convictions. A DUI combined with another qualifying major offense can trigger it. The driver’s complete history must be reviewed.

Is the Alcohol Limit Lower for Commercial Drivers?

When operating a commercial motor vehicle, an alcohol concentration of 0.04 or greater is a separate basis for commercial disqualification. Federal regulations identify this alongside DUI and refusal to take a required alcohol test as major disqualifying offenses.

Holding a CDL does not automatically make 0.04 the DUI threshold when driving a personal car. Florida’s general DUI statute applies when a driver’s normal faculties are impaired by alcohol or specified substances, or when the driver has a blood- or breath-alcohol level of 0.08 or higher. A reading below 0.08 does not necessarily prevent an impairment-based DUI prosecution.

Can Your CDL Be Affected Before a Conviction?

Yes. An arrest is not a conviction, but an administrative disqualification can begin before the criminal case is resolved.

Florida Statutes section 322.64 authorizes separate commercial disqualification for specified unlawful-alcohol-level and test-refusal circumstances. The disqualification begins on the date the notice is issued.

A driver may request formal or informal review within 10 days after issuance of the notice of disqualification. Any temporary permit issued under this provision authorizes only noncommercial driving, subject to eligibility. It does not allow the driver to continue operating a commercial vehicle.

What Happens If You Refuse a Breath Test?

Refusing a lawfully required alcohol test can itself trigger commercial disqualification. Under federal rules, a first qualifying refusal generally carries a one-year disqualification, with increased consequences for certain hazardous-materials operations and subsequent qualifying incidents.

A driver should not assume that refusing testing protects a CDL or that avoiding a DUI conviction necessarily resolves the refusal consequences.

Can You Get a Hardship CDL to Keep Working?

No. A hardship license does not authorize operation of a commercial motor vehicle during a commercial disqualification.

FLHSMV expressly states that drivers disqualified from operating commercial vehicles cannot obtain a hardship license to operate one. Depending on eligibility, a driver may obtain restricted noncommercial driving privileges, but those privileges do not permit a return to commercial driving.

This distinction is especially important for truck drivers, bus drivers, and others whose employment requires a CDL.

Does a Dismissed or Reduced DUI Charge Automatically Protect Your CDL?

Do not assume that the criminal case’s outcome resolves every licensing issue. The administrative proceeding must be addressed separately, and Florida law treats an administrative disqualification under section 322.64 as a conviction for purposes of calculating federal commercial-disqualification periods.

Before accepting a proposed resolution, have counsel examine the criminal charge, administrative notices, driving record, and potential commercial-license consequences together.
