CDL DUI Defense in Jacksonville
Eagle Rock Defense Group represents commercial drivers facing DUI charges in Jacksonville and across Northeast Florida. CDL holders face stricter BAC limits (0.04% versus 0.08%), mandatory disqualification periods, and career-ending consequences that require immediate, specialized defense to protect their livelihood and driving privileges.
Commercial drivers convicted of DUI face mandatory CDL disqualification under Florida law, even for a first offense committed in their personal vehicle. The legal threshold for commercial drivers is 0.04% BAC — half the limit that applies to non-commercial motorists — and a conviction triggers an automatic one-year disqualification from operating any commercial motor vehicle.1 For drivers transporting hazardous materials, that period extends to three years.2

What Makes CDL DUI Cases Different From Regular DUI Charges?
CDL holders are subject to a 0.04% BAC limit when operating a commercial vehicle and face automatic disqualification penalties that do not apply to non-commercial drivers. Florida Statute 322.62 establishes that any person driving a commercial motor vehicle with a BAC of 0.04% or higher commits a DUI offense, regardless of whether they exhibit signs of impairment.1 This is a strict liability standard — the state does not need to prove you were actually impaired, only that your BAC met or exceeded the threshold.
Even when driving your personal vehicle off-duty, you remain subject to standard DUI laws under Florida Statute 316.193, but a conviction still triggers CDL disqualification under Section 322.61.23 The Florida DHSMV automatically processes the disqualification upon notification of conviction, regardless of whether the judge imposes a hardship license for personal driving.4 There is no hardship or business-purposes-only CDL available during the disqualification period.
How Long Is CDL Disqualification for a First DUI?
A first DUI conviction results in a one-year CDL disqualification, or three years if you were transporting hazardous materials at the time of the offense. Florida Statute 322.61 mandates these periods with no exception for work-related need or economic hardship.2 A second DUI conviction — even decades after the first — triggers lifetime disqualification from holding a commercial driver license.
The disqualification clock begins on the date of conviction, not the date of arrest. If you plead no contest or are found guilty at trial, the DHSMV receives notice within days and issues the disqualification order. The one-year period applies even if the underlying criminal DUI charge is reduced to reckless driving, so long as the original charge was DUI and you held a CDL at the time. Refusing a breath, blood, or urine test when requested by law enforcement adds a separate one-year disqualification on top of any conviction-based penalty.
Can You Get a Hardship License to Keep Driving Commercially?
No hardship or restricted CDL exists under Florida law. While non-commercial drivers may petition for business-purposes-only licenses after enrolling in DUI school, commercial drivers facing disqualification have no similar avenue.4 The disqualification is absolute for the entire administrative suspension term. You may be eligible for a hardship license to drive a personal vehicle for work, medical appointments, or education, but that license does not authorize operation of any vehicle requiring a CDL.
This means most CDL holders lose their employment immediately upon conviction. Trucking companies, transit agencies, and delivery services typically terminate drivers who cannot legally operate commercial vehicles, even if the DUI occurred off-duty in a personal car. The economic impact is severe: one year without CDL privileges often means one year without income in your chosen profession, plus the challenge of finding an employer willing to hire a driver with a DUI conviction after reinstatement.
What Defenses Apply in CDL DUI Cases?
CDL DUI cases can be challenged on the same procedural, technical, and constitutional grounds as any DUI arrest, including unlawful stop, inaccurate testing, and failure to observe mandatory waiting periods before breath testing. In Jacksonville and the surrounding counties, we examine whether the traffic stop was supported by reasonable suspicion, whether field sobriety exercises were conducted according to National Highway Traffic Safety Administration standards, and whether the arresting officer followed Florida Administrative Code rules governing breath test administration.1
Breath test results depend on proper calibration, maintenance logs, and a twenty-minute observation period free of eating, drinking, smoking, or regurgitation. Blood test results can be challenged based on chain-of-custody gaps, contamination, or improper storage. Because the 0.04% threshold is so low for commercial vehicle operators, even minor testing errors or residual mouth alcohol can produce a false positive. Suppression of breath or blood evidence often leads prosecutors to reduce or dismiss charges when their case depends entirely on chemical test results.
| Driver Type | BAC Limit | First Offense Penalty | Hardship License Available? |
|---|---|---|---|
| Non-commercial (personal vehicle) | 0.08% | 6-month license suspension | Yes, after 30 days |
| CDL holder (personal vehicle, off-duty) | 0.08% | 1-year CDL disqualification + criminal penalties | No CDL hardship; personal hardship only |
| CDL holder (operating CMV) | 0.04% | 1-year CDL disqualification + criminal penalties | No CDL hardship; personal hardship only |
| CDL holder (CMV with hazmat) | 0.04% | 3-year CDL disqualification + criminal penalties | No CDL hardship; personal hardship only |
Why Immediate Action Matters After a CDL DUI Arrest
You have only ten days from the date of arrest to request a formal review hearing with the DHSMV to challenge an administrative suspension of your driving privileges. The formal review hearing is separate from your criminal case and offers an early chance to preserve your driving privileges while the criminal case proceeds.
Early retention of a defense attorney also allows us to subpoena dash-cam and body-cam footage, calibration records for the breath test instrument, and dispatch logs before they are overwritten or destroyed. In Jacksonville, the Sheriff’s Office and Jacksonville Beach Police Department typically retain video for 90 days unless a legal hold is placed. Requesting these records on day 89 is often too late. We also investigate whether the traffic stop occurred at a location known for pretextual enforcement or whether the arresting officer has a history of dismissed DUI cases due to procedural errors.
If you hold a CDL and were arrested for DUI anywhere in Duval, St. Johns, Nassau, Clay, Flagler, Baker, or Bradford County, call Eagle Rock Defense Group at 904-310-7501 for a confidential consultation. We will review the arrest report, identify defenses, and file your formal review hearing request before the ten-day deadline expires.
Frequently Asked Questions
Does a DUI in my personal car affect my CDL?
Yes. Florida Statute 322.61 mandates CDL disqualification for any DUI conviction, regardless of whether you were driving a commercial vehicle at the time. The one-year disqualification applies even if the offense occurred off-duty in your own passenger car.
Can I keep my CDL if I plead to reckless driving?
It depends on how the plea is structured. If the original charge was DUI and you held a CDL, the DHSMV may still impose disqualification even after a reduction to reckless driving. Negotiating a withhold of adjudication on a reduced charge can sometimes avoid disqualification, but this outcome is not guaranteed and depends on prosecutorial discretion and your prior record.
What happens if I refuse the breath test?
Refusal to submit to a lawful breath, blood, or urine test results is an automatic one-year CDL disqualification under Florida’s implied consent law and is a separate misdemeanor offense in and of itself separate from any criminal DUI charge. If you are later convicted of DUI, the refusal disqualification runs concurrently with the conviction-based disqualification, but you face both the criminal penalties and the administrative suspension.
How do I get my CDL back after disqualification?
After the one- or three-year disqualification period ends, you must apply for reinstatement with the DHSMV, pay reinstatement fees, provide proof of completion of DUI school and any other court-ordered requirements, and possibly retake the CDL knowledge and skills tests. You will also need SR-22 insurance and must disclose the DUI conviction to any prospective employer, as it remains on your driving record.
Will my employer find out about the DUI arrest before conviction?
Federal Motor Carrier Safety Administration regulations require you to notify your employer within 30 days of any traffic conviction, but notification is not required for an arrest alone. However, if your license is administratively suspended following the arrest, your inability to legally drive will become apparent immediately. Many employers conduct periodic motor vehicle record checks and will discover pending charges. Related Resources:
