⚠️ CDL DUI arrested? First offense = 1-year disqualification. Second offense = lifetime ban in California. Your career is on the line. Call David Chesley now — (800) 755-5174
Your CDL Is Your Livelihood. A DUI Conviction Ends It.
You drive for a living. The commercial driver's license in your wallet is not just a credential — it is your income, your career, your family's financial security. And now you have been arrested for DUI. Maybe you were driving your commercial vehicle. Maybe you were driving your personal car on your day off. It does not matter. Under federal and California law, a DUI conviction triggers an automatic one-year CDL disqualification for a first offense. A second DUI conviction — even years later, even in a personal vehicle — results in a permanent, lifetime CDL disqualification with no reinstatement option in California.
This is not a suspended license you can get back after a few months. This is not a fine you can pay and move on. This is the permanent loss of your ability to earn a living in the only profession you know. No restricted CDL exists. No hardship license applies to commercial driving. No employer will hire you without a valid CDL. One conviction, and you are out of the industry for a year. Two convictions, and you are out forever.
The stakes for a CDL holder facing a DUI are not the same as for a regular driver. The BAC limit is half. The consequences are exponentially worse. And the timeline to fight — both the criminal case and the DMV disqualification — is measured in days, not weeks.

Why CDL DUI Cases Are Different — and Harder
Commercial drivers operate under a different legal framework than regular drivers. You are subject to both California state law and federal regulations from the Federal Motor Carrier Safety Administration (FMCSA). This dual jurisdiction creates harsher rules, lower limits, and more severe consequences.
The BAC limit is 0.04% — half the standard limit. Under California Vehicle Code § 23152(d) and federal FMCSA regulations, it is unlawful to drive a commercial vehicle with a blood alcohol concentration of 0.04% or higher. This is not 0.08%. This is 0.04%. One or two drinks can put you over the limit. At 0.04%, you may show no visible signs of impairment. You may be driving perfectly safely. None of that matters. The statute presumes intoxication from the measured BAC alone.
The 0.04% limit applies only when you are driving a commercial vehicle. If you are driving your personal car, the standard 0.08% limit applies. But here is the critical point: a DUI conviction in your personal vehicle still triggers CDL disqualification. You can be arrested for a 0.09% BAC in your personal vehicle on your day off, convicted of a standard misdemeanor DUI under VC § 23152(a) or (b), and lose your CDL for a year even though you were not driving commercially at the time.
There is no restricted CDL. Regular drivers can often obtain a restricted license that allows them to drive to work, to school, to medical appointments. Commercial drivers cannot. Federal law does not allow restricted commercial driving privileges during a disqualification period. If your CDL is disqualified, you cannot drive any commercial vehicle at all — not to work, not for training, not for any reason. Your income stops the day the disqualification takes effect.
A second DUI is a lifetime ban in California. Under 49 CFR § 383.51 and California law (VC § 15302), a second DUI conviction — whether in a commercial vehicle or a personal vehicle, whether five years later or fifteen years later — results in permanent, lifetime disqualification of your CDL. California does not offer reinstatement after ten years (though federal law allows states to permit it in some cases with rehabilitation). In California, a second DUI conviction means you will never hold a CDL again.
CDL Disqualification Penalties — First Offense vs. Second Offense
The difference between a first CDL DUI and a second is not a matter of degree. It is the difference between a one-year suspension and a permanent career-ending ban.
First DUI Offense — One-Year CDL Disqualification:
- A first DUI conviction — whether you were driving a commercial vehicle with a 0.04% BAC or a personal vehicle with a 0.08% BAC — results in a mandatory one-year disqualification of your CDL. This applies under both federal FMCSA regulations and California law. The disqualification is automatic upon conviction. There is no judicial discretion to reduce it, no hardship exception, and no restricted CDL available for commercial driving.
- If you were transporting hazardous materials at the time of the DUI, the disqualification period extends to three years rather than one.
- If you refused chemical testing after a lawful DUI arrest, the CDL disqualification is also one year (or three years if transporting hazmat). Chemical test refusal carries its own set of DMV penalties on top of the criminal case, and for CDL holders, refusal is almost always a worse outcome than submitting to testing.
- During the one-year disqualification, you cannot drive any commercial vehicle. You can, however, apply to downgrade your license to a regular Class C (car) or Class M (motorcycle) license and obtain a restricted license for personal driving if you meet the requirements. This allows you to drive a personal vehicle to work — but it does not allow you to work as a commercial driver.
- After the one-year disqualification period ends, you can reapply for your CDL. You will need to pass the written knowledge test and the skills test again, meet all medical certification requirements, and pay reinstatement fees. There is no guarantee of reemployment — most trucking companies have policies against hiring drivers with DUI convictions, even after reinstatement.
Second DUI Offense — Lifetime CDL Disqualification:
- A second DUI conviction triggers permanent, lifetime disqualification of your CDL under federal law (49 CFR § 383.51) and California law (VC § 15302). This applies regardless of how much time has passed since the first DUI. A first DUI in 2015 and a second DUI in 2026 results in lifetime disqualification.
- The second DUI does not need to occur in a commercial vehicle. A DUI in your personal car counts. An out-of-state DUI counts. A wet reckless conviction counts as a prior for CDL disqualification purposes, even though it is technically a reckless driving charge under VC § 23103.5.
- Federal law allows states to offer reinstatement after ten years if the driver successfully completes a state-approved rehabilitation program. California does not offer this option. In California, a second DUI conviction means permanent loss of your CDL with no possibility of reinstatement, ever.
This is why the stakes on a first CDL DUI are so high. You are not just fighting to avoid a one-year disqualification. You are fighting to preserve your eligibility to work in this industry for the rest of your life. One conviction puts you one arrest away from a permanent ban.
The Dual Threat: Criminal Case and DMV Disqualification
A CDL DUI triggers two separate proceedings: the criminal case in court and the administrative disqualification by the DMV. Both must be fought, and they operate on different timelines with different rules.
The Criminal Case:
The criminal DUI charge is prosecuted in Superior Court under Vehicle Code § 23152(d) if you were driving a commercial vehicle, or under VC § 23152(a)/(b) if you were driving a personal vehicle. The penalties for the criminal conviction are similar to a standard DUI: jail time (up to six months for a first offense), fines ($390 to $1,000 base plus penalty assessments), DUI school, probation, and all the standard DUI conditions.
The criminal case is where your attorney challenges the evidence: Was the traffic stop lawful? Was there probable cause for the arrest? Was the breathalyzer properly calibrated and maintained? Was the blood sample collected, stored, and tested in compliance with Title 17 regulations? Was the BAC test conducted within three hours of driving? If the prosecution cannot prove the DUI beyond a reasonable doubt, the case is dismissed and the CDL disqualification does not occur.
The DMV Administrative Disqualification:
Separately from the criminal case, the DMV initiates an administrative action to disqualify your CDL. This happens automatically when you are arrested for DUI while holding a CDL — the arresting officer confiscates your license and issues a temporary driving permit, and the DMV disqualification process begins.
You have ten days from the date of arrest to request an administrative hearing to challenge the disqualification. If you do not request a hearing within ten days, the disqualification goes into effect automatically after 30 days. The DMV hearing is your opportunity to contest the disqualification on administrative grounds: Did the officer have reasonable cause to stop you? Did the officer have probable cause to arrest you? Was your BAC 0.04% or higher (for a commercial vehicle) or 0.08% or higher (for a personal vehicle) at the time of driving?
The DMV hearing operates under a lower burden of proof than the criminal case. The DMV only needs to show by a preponderance of the evidence (more likely than not) that you were driving with an unlawful BAC. Hearsay is admissible. The hearing officer — not a judge — makes the decision.
Winning the DMV hearing prevents the automatic administrative disqualification, which buys time and preserves your ability to drive commercially while the criminal case is pending. Losing the DMV hearing results in immediate disqualification.
Special Rules That Make CDL DUI Cases Harder
Beyond the lower BAC limit and the harsher disqualification penalties, CDL holders face additional legal burdens that do not apply to regular drivers.
- Employer notification is mandatory. Under federal FMCSA regulations, you must notify your employer within 30 days of any traffic conviction, including a DUI. Failure to notify can result in separate penalties and termination. Most trucking companies terminate drivers upon DUI arrest — before conviction — due to insurance requirements and company policy.
- Out-of-state convictions count. If you are licensed in California but arrested for DUI in Nevada, Arizona, Oregon, or any other state, the conviction is reported to California and triggers the same CDL disqualification as a California DUI. Interstate commerce means your driving record follows you across state lines.
- The FMCSA Drug and Alcohol Clearinghouse tracks all violations. Every DUI, every refusal, every disqualification is entered into a national database maintained by the FMCSA. Employers are required to check the Clearinghouse before hiring any CDL driver. A DUI conviction in the Clearinghouse makes you effectively unemployable in the industry, even after reinstatement, because most carriers will not hire drivers with Clearinghouse violations.
- No "wet reckless" benefit for CDL disqualification purposes. In a standard DUI case, reducing the charge to a wet reckless under VC § 23103.5 avoids some of the harsher DUI penalties. For CDL holders, a wet reckless conviction still counts as a DUI for federal disqualification purposes. The FMCSA treats wet reckless as a major offense, and the one-year disqualification applies. A wet reckless is better than a DUI conviction for criminal sentencing and personal license purposes, but it does not save your CDL.
- You cannot get court supervision to avoid the conviction. In some states, CDL holders charged with DUI can seek "court supervision" or "deferred adjudication," where successful completion of probation results in no conviction being entered. California does not offer this for DUI cases, and even if it did, federal FMCSA regulations do not recognize court supervision as avoiding disqualification. For CDL purposes, a guilty plea with supervision is treated the same as a conviction.
Defending a CDL DUI — Where the Fight Is
A CDL DUI defense operates on multiple fronts: challenging the criminal DUI case, fighting the DMV disqualification hearing, and negotiating for the best possible outcome when the evidence is difficult to overcome.
- Challenge the underlying DUI arrest. Every element of a standard DUI defense applies here. Was the traffic stop supported by reasonable suspicion? Did the officer have probable cause to arrest? Were field sobriety tests administered according to NHTSA standards? Was the breathalyzer calibrated within the required timeframe? Was the blood sample properly collected, stored, and tested under Title 17? Was the BAC result reliable, or are there physiological factors — rising BAC, mouth alcohol, GERD, diabetes — that could produce a false reading? If the DUI cannot be proven beyond a reasonable doubt, the case is dismissed. No conviction means no CDL disqualification.
- Fight the DMV hearing aggressively. The ten-day window to request a DMV hearing is critical. Missing this deadline forfeits your right to contest the administrative disqualification. At the DMV hearing, your attorney cross-examines the arresting officer, challenges the reliability of the chemical test, and presents evidence contesting the disqualification. Winning the DMV hearing keeps your CDL valid while the criminal case is pending, which preserves your income and your job.
- Negotiate for a charge reduction. If the DUI evidence is strong, the goal shifts to the best possible resolution. For CDL holders, "best possible" often means avoiding a DUI conviction altogether. A reduction to a dry reckless (VC § 23103 without the alcohol enhancement) avoids CDL disqualification because it is not a DUI-related offense under federal law. This is difficult to achieve and requires weak DUI evidence or significant mitigating factors, but it is the outcome that saves your CDL. A wet reckless (VC § 23103.5) is better than a DUI for criminal sentencing purposes, but as noted above, it still triggers CDL disqualification under federal law. If a dry reckless is not achievable, a wet reckless at least avoids the harsher criminal DUI penalties and preserves some future flexibility.
- Present mitigating evidence to support negotiation. Prosecutors and judges consider the totality of the circumstances. If your BAC was barely over the limit (0.05% in a commercial vehicle, 0.09% in a personal vehicle), if you have no prior record, if you have completed alcohol treatment since the arrest, if you have a long history of safe commercial driving, these factors support a reduction. An attorney who knows how to present this evidence persuasively can influence the outcome.
- Understand what victory looks like. For a CDL holder, "winning" a DUI case does not necessarily mean a trial acquittal. It means avoiding a DUI conviction — through dismissal, reduction, or suppression of evidence — so that the CDL disqualification does not occur. That is the only outcome that preserves your career.
Frequently Asked Questions About CDL DUI in California
Does a DUI in my personal car affect my CDL?
Yes. A DUI conviction in your personal vehicle — even on your day off, even with no commercial driving involved — triggers the same one-year CDL disqualification as a DUI in a commercial vehicle. Federal FMCSA regulations require CDL disqualification for any DUI conviction, regardless of the type of vehicle you were driving.
Can I get a restricted CDL to drive to work?
No. Federal law does not allow restricted commercial driving privileges during a disqualification period. If your CDL is disqualified, you cannot drive any commercial vehicle for any reason. You may be able to downgrade to a regular Class C license and obtain a restricted license for personal driving, but that does not allow you to work.
What is the BAC limit for CDL holders?
It depends on what you are driving. If you are driving a commercial vehicle, the BAC limit is 0.04% under VC § 23152(d). If you are driving your personal car, the standard 0.08% limit applies. However, a conviction at either level triggers CDL disqualification.
Will my employer find out about my DUI arrest?
Yes. You are required by federal FMCSA regulations to notify your employer within 30 days of any traffic conviction, including a DUI. Additionally, most employers conduct regular checks of the FMCSA Drug and Alcohol Clearinghouse, which tracks all DUI arrests and convictions for CDL holders. In practice, most trucking companies terminate drivers immediately upon DUI arrest due to insurance and liability concerns.
Can I get my CDL back after a lifetime disqualification?
Not in California. Federal law allows states to offer reinstatement after ten years if the driver completes a state-approved rehabilitation program. California does not offer this option. A second DUI conviction in California results in permanent lifetime disqualification with no possibility of reinstatement, ever.
Does a wet reckless conviction avoid CDL disqualification?
No. While a wet reckless (VC § 23103.5) is treated more favorably than a DUI for criminal sentencing purposes, federal FMCSA regulations treat wet reckless as a major offense for CDL disqualification purposes. A wet reckless conviction still triggers the one-year disqualification. Only a dry reckless (VC § 23103 with no alcohol enhancement) avoids CDL disqualification.
What happens if I refuse a chemical test?
Refusal to submit to a chemical test after a lawful DUI arrest triggers a one-year CDL disqualification (or three years if you were transporting hazardous materials). The refusal is treated the same as a DUI conviction for disqualification purposes. Additionally, refusal carries enhanced DMV penalties and makes defending the criminal case more difficult.
Your Career Depends on What Happens in the Next 10 Days
You have been arrested for DUI. The criminal case will take months to resolve. But the DMV disqualification process moves on a ten-day clock. You have ten days from the date of arrest to request a hearing to challenge the administrative disqualification of your CDL. If you do not request the hearing within ten days, the disqualification takes effect automatically after 30 days, and you lose the ability to contest it.
While the DMV hearing is pending, you can continue driving commercially. If you win the hearing, the administrative disqualification is set aside and your CDL remains valid while the criminal case proceeds. If you lose the hearing but win the criminal case, the disqualification is eventually lifted. But if you never request the hearing, you forfeit your only chance to delay or prevent the disqualification.
This is not a case where you can wait and see what happens. This is a case where the decisions you make in the first 72 hours determine whether you are still employed next month.
