You can only keep your CDL after a DUI arrest if the case does not end in a conviction or an administrative finding that triggers disqualification. Federal rules leave very little room: there is no diversion, no deferred judgment, and no hardship CDL. Your realistic options are to act fast on the administrative hearing, challenge the stop and the test evidence, and fight for dismissal, acquittal, or a reduction the facts actually support.
Key takeaways
- A DUI conviction or test refusal in any vehicle means a mandatory CDL disqualification: 1 year for a first offense, 3 years if hauling hazmat, life for a second.
- Federal law bars states from masking, deferring, or diverting a CDL holder’s conviction.
- Administrative hearing deadlines are short, often 10 to 30 days depending on the state.
- The paths that save a CDL are a suppressed stop or test, an acquittal, a dismissal, or a fact based reduction to a non disqualifying offense.
- You must tell your employer about a disqualification by the end of the next business day.
The honest starting point
Most “save your license” advice is written for regular drivers, and much of it does not apply to you. Under 49 CFR 383.51, a CDL holder convicted of driving under the influence, or who refuses an implied consent test, is disqualified from driving a commercial motor vehicle for at least 1 year. That is true in a CMV or in your own pickup. A conviction in a CMV at 0.04 or higher triggers the same result, even though 0.08 is the limit for everyone else. See the 0.04 vs 0.08 limit for how that works.
The federal definition of “conviction” is broad. It includes a guilty or no contest plea, a finding by an administrative tribunal, a forfeited bond, or even paying the fine, whether or not the sentence is suspended or probated. If any of those happen on a DUI charge, the disqualification is mandatory. A judge cannot waive it, and your state cannot issue you a temporary or provisional CDL during it under 49 CFR 384.210. Our page on the CDL hardship license explains why a work permit for your car does not let you drive a truck.
So keeping your CDL means avoiding the conviction or the disqualifying administrative finding in the first place. Here is how drivers and their attorneys approach that.
Step 1: Meet the administrative hearing deadline
A DUI arrest usually starts two separate cases. The criminal case runs in court. The administrative case runs through your state’s licensing agency and decides whether your license is suspended based on the test result or refusal. In many states the administrative finding can disqualify your CDL even if the criminal case is later reduced or dismissed, so you cannot ignore it.
The window to request the hearing is short and varies by state. Texas gives 15 days from the notice, California and Florida give 10 days, and Georgia and Arizona give 30 days. Miss it and the suspension usually takes effect automatically. Read the notice the officer gave you, and see our full guide to the CDL DUI administrative hearing.
Even when the hearing is hard to win, it often gives your attorney a chance to question the officer under oath and see the evidence early, which can help the criminal defense.
Step 2: Challenge the stop and the arrest
Police need a legal reason to pull you over and probable cause to arrest you. If the stop was not justified, or the arrest was made without enough evidence, a court may suppress the evidence that followed, including the breath or blood result. Without that evidence, many DUI cases cannot move forward.
Things an attorney will look at include:
- The stated reason for the stop, compared with dash cam or body cam video
- Whether a checkpoint followed the rules your state requires
- How field sobriety tests were given, and whether conditions (weather, footwear, a sloped shoulder, fatigue after a long shift) affected them
- Whether the officer had probable cause before making the arrest
Step 3: Examine the breath or blood test
Chemical test results are often the core of the case, and they are not beyond question.
Breath tests
Evidential breath machines must be maintained, calibrated, and operated according to state rules, usually with an observation period before the test. Maintenance logs, operator certification, and the testing sequence can all be reviewed. Mouth alcohol, certain medical conditions, and timing issues are sometimes raised.
Blood tests
Blood cases turn on how the sample was drawn, stored, labeled, and analyzed. Chain of custody gaps, lab errors, and fermentation or preservative problems are common lines of attack. Your attorney may request a split sample for independent retesting.
Refusals
If you refused, the question shifts to whether you were properly warned of the consequences and whether what happened legally counts as a refusal under your state’s law. A refusal is a major offense on its own. Our guide to refusing a breath test with a CDL covers the details.
Step 4: A reduced charge, only if the facts support it
This is where CDL holders get the most bad advice. The federal masking rule, 49 CFR 384.226, says a state must not mask, defer imposition of judgment, or allow diversion that keeps a CDL holder’s traffic conviction off the record, in any type of vehicle. That shuts the door on first offender programs, deferred adjudication, and “probation before judgment” style deals that regular drivers often use. Read more in our CDL masking law guide.
What the masking rule targets is hiding or deferring a conviction. A genuine plea to a different offense that is then reported as what it is, such as reckless driving, is handled differently. Whether a prosecutor will offer that depends on the evidence. If the test result is weak, the stop is questionable, or a key witness is unavailable, a reduction may be realistic. If the evidence is strong, it usually is not.
Keep in mind that a reduced charge still has consequences. Reckless driving is a “serious traffic violation” under Table 2 of 383.51, and two serious violations within 3 years bring a 60 day disqualification (for violations in a personal vehicle, only if the conviction leads to a suspension or revocation of your license). Some states also treat certain alcohol related reductions as a DUI for licensing purposes. Ask a licensed attorney in your state exactly how any proposed plea will appear on your CDLIS driver record before you accept it.
Step 5: Dismissal or acquittal
If the evidence is suppressed, the prosecutor may dismiss the case. If the case goes to trial and you are found not guilty, there is no conviction under 383.51. Either outcome protects you from the criminal side disqualification. You still need to deal with the administrative side, which may have been decided separately. Rules differ by state on whether an acquittal undoes an administrative suspension, so ask about this early.
When the disqualification starts
Federal rules require the state to disqualify a driver “as expeditiously as possible” after a disqualifying conviction. In practice, timing depends on your state and on which track acts first. An administrative suspension can begin within days or weeks of the arrest if no hearing is requested. A criminal conviction disqualification starts once the court reports the conviction to the licensing agency. The disqualification is added to any other periods you are already serving. You can estimate the length with our free CDL disqualification checker.
What happens to your job
Federal rules put notification duties on you:
- Under 49 CFR 383.33, you must notify your employer of a suspension, revocation, or disqualification before the end of the business day after you receive notice of it.
- Under 49 CFR 383.31, you must notify your employer in writing within 30 days of a conviction for any traffic violation other than parking, in any vehicle.
An employer cannot let a disqualified driver operate a CMV, so a disqualification means you cannot drive for that period. Whether you keep a non driving position is up to the company. If the arrest happened while driving a CMV, a citation for driving a CMV under the influence counts as “actual knowledge” under 49 CFR 382.107, which can lead to a Clearinghouse report and the return to duty process. See the Clearinghouse guide, and for the longer view, trucking jobs after a DUI.
What to do this week
- Find the notice the officer gave you and note the hearing deadline.
- Talk to a licensed attorney in your state who handles CDL cases, before the deadline.
- Write down everything you remember about the stop, the tests, and what was said.
- Do not plead guilty, pay a fine, or sign a diversion agreement until you understand how it affects your CDL.
- Plan your employer notification so you meet the federal deadlines.

Frequently asked questions
Can I keep my CDL if I am convicted of DUI?
No. A DUI conviction in any vehicle triggers a mandatory CDL disqualification of at least 1 year under 49 CFR 383.51, 3 years if you were hauling hazmat, and life for a second offense. You may be able to keep a regular license on restrictions, but not drive a CMV.
Can I get a DUI deferred or diverted to protect my CDL?
No. Federal law, 49 CFR 384.226, forbids states from masking, deferring judgment, or allowing diversion that would keep a CDL holder’s conviction off the record, in any type of vehicle.
Can a DUI be reduced to reckless driving for a CDL holder?
Sometimes, if the evidence supports it and the prosecutor agrees. A real plea to a different offense is not the same as masking, but it still goes on your record. Reckless driving is a serious traffic violation, and two within 3 years can mean a 60 day disqualification.
How long do I have to request a hearing to save my CDL?
It depends on your state, and it is often short. Texas allows 15 days, California and Florida 10 days, and Georgia and Arizona 30 days. Check the notice you received and talk to an attorney right away.
Do I have to tell my employer about a DUI arrest?
Federal rules require you to notify your employer of a suspension or disqualification by the end of the next business day, and of a conviction in writing within 30 days. Your employer’s policy may require you to report an arrest sooner.
