For commercial drivers, a DUI conviction in Florida is categorically more severe than for non-CDL holders. A single DUI can end a trucking career. Understanding the CDL-specific consequences — and how FR44 fits in — is essential for any commercial driver facing a DUI charge in Florida.

CDL and DUI: The Federal Standard

CDL holders are subject to both Florida state DUI law and federal FMCSA (Federal Motor Carrier Safety Administration) regulations. These run on separate tracks:

• Florida criminal DUI (0.08%+): Standard DUI charges apply regardless of CDL status
• FMCSA/CDL disqualification (0.04%+ while operating CMV): 0.04% BAC in a commercial motor vehicle triggers CDL disqualification — half the adult threshold
• Personal vehicle DUI (0.08%+): Still triggers CDL disqualification under FMCSA rules — a DUI in your personal pickup truck disqualifies your CDL

CDL Disqualification Timeline

Offense	CDL Disqualification	Notes
First DUI (personal vehicle)	1 year	3 years if transporting hazmat at time of offense
First DUI (CMV)	1 year (minimum)	3 years if hazmat
Second DUI (any vehicle)	Lifetime disqualification	Permanent under federal law
Refusal of chemical test	1 year (treated same as DUI)	Implied consent applies to CDL holders
Leaving scene of accident (CMV)	1 year
Felony involving CMV	Lifetime

The lifetime CDL disqualification for a second serious traffic violation is federal law — no state-level appeal, no hardship exception, no reinstatement path in most circumstances. A CDL holder with two DUIs at any point in their lifetime loses their CDL permanently.

Florida License vs CDL: Two Separate Issues

The Florida regular license and the CDL are distinct. A DUI conviction may suspend your Florida driver license for 6 months to 1 year (standard first offense). Separately, FMCSA requires CDL disqualification for 1 year from the same offense. These timelines run simultaneously but are administered by different systems:

• Florida DHSMV handles your regular Class E license — FR44 and hardship license apply here
• FMCSA/CDLIS (Commercial Driver License Information System) handles CDL disqualification — FR44 and hardship licenses do NOT apply to CDL driving privileges

Getting FR44 and a hardship license lets you drive a personal vehicle during your FL license suspension. It does NOT restore your ability to operate a commercial motor vehicle. CDL disqualification is absolute during the disqualification period — no hardship CDL exists under federal law.

Employment Consequences

Employers are required to check the CDL driver’s Pre-Employment Screening Program (PSP) record, which includes roadside inspection violations and crashes. A DUI conviction triggers mandatory reporting to FMCSA and shows in the PSP. Most carriers will not hire a driver with a DUI conviction in the past 3-7 years, and some have lifetime exclusions for DUI. FMCSA’s Drug and Alcohol Clearinghouse also records violations — visible to all motor carriers.

FR44 for CDL Holders After DUI

FR44 is required to reinstate your Florida personal driver license after a DUI — the same 100/300/50 coverage for 3 years from reinstatement. Get this filed as early as possible to maintain your personal license (driving personal vehicles). Your personal license reinstatement does not affect your CDL disqualification timeline, but maintaining your regular license is essential for daily life during the 1-year CDL period and for the path back to commercial driving after the CDL disqualification expires.
