Usually not for a first offense. A single misdemeanor DUI rarely ends a nursing, teaching, or real estate career in California. But you will have to report it, or your licensing board will find out on its own, and how the case resolves matters more than most people realize. Commercial drivers are the exception. For a CDL holder, a first DUI conviction in any vehicle means a one-year disqualification with no restricted license.
Orange County runs on licensed work. Nurses at Hoag, MemorialCare, UCI Health, and Kaiser. Teachers in the districts under the Orange County Department of Education. Real estate agents in every city from Seal Beach to San Clemente. Truckers moving containers out of the Ports of Long Beach and Los Angeles. A DUI arrest for any of them starts two cases, one in criminal court and one with a licensing body, and the second case is usually the one people are least prepared for.
How Licensing Boards Find Out About a DUI
They find out from the Department of Justice, and they find out fast. Every licensed nurse, credentialed teacher, and real estate licensee in California was fingerprinted through Live Scan when they applied. Those prints stay on file with a flag that tells the DOJ to notify the licensing agency of any subsequent arrest. When you are booked for DUI and fingerprinted, the match triggers an automatic notice to your board.
So “will they find out” is the wrong question. The board typically knows about the arrest before your first court date. The real questions are whether you have a separate duty to report, what the deadline is, and what the board does with the information once the case resolves.
What “Substantially Related” Means
Under Business and Professions Code Section 490, a board can suspend or revoke a license when the licensee is convicted of a crime that is substantially related to the qualifications, functions, or duties of the profession. Each board has its own regulations spelling out what that means for its licensees.
For a first DUI with no aggravating facts, boards often conclude the conviction is not substantially related, or that it is related but does not warrant formal discipline. The facts that change that analysis are the ones you would expect: a high blood alcohol level, a collision, an injury, a child in the car, a prior DUI, or any connection to the job, such as driving to a shift, driving a work vehicle, or a teacher arrested on a school day.
Does a DUI Affect Your Nursing License in California?
The Board of Registered Nursing has the most specific rule of any board in this post. Under Title 16, California Code of Regulations, Section 1441(c), a registered nurse must report any conviction, including a plea of guilty or no contest, to the Board within 30 days. Failing to report within 30 days is itself unprofessional conduct, separate from whatever the DUI is. The Board has also written into the same regulation that failing to produce requested documents within 15 days, or failing to cooperate with a Board investigation, is unprofessional conduct.
The 30 days runs from the conviction, not the arrest. A pending case does not have to be reported under Section 1441(c), though it will need to be disclosed on your next renewal application, and the Board already knows about the arrest from the DOJ.
The Board’s regulations on substantial relationship and rehabilitation were rewritten after AB 2138 took effect in 2020. Under those rules, the Board considers the nature of the crime, the time that has passed, and the evidence of rehabilitation. For a first misdemeanor DUI with a low BAC and no collision, the common outcomes are a closed file, a public letter of reprimand, or a citation. Probation with terms such as alcohol testing and worksite monitoring becomes more likely with a high BAC, a prior, or a refusal. Revocation for a single DUI is uncommon. None of that is guaranteed, and the Board’s response is shaped by what it sees in the court file and what you send it.
Does a DUI Affect a Teaching Credential?
The Commission on Teacher Credentialing does not set a standalone deadline for a credential holder to self-report a DUI conviction. Two other things happen instead. The DOJ notifies the Commission of the arrest through the fingerprint match, and you must disclose the conviction on your next credential renewal or application. Answering that question falsely is treated as falsification of the application, which is a far bigger problem than the DUI.
Once notified, the Committee of Credentials has authority under Education Code Section 44242.5 to open a discretionary review of your fitness to hold a credential. For a single misdemeanor DUI with nothing else attached, the Committee often takes no action or closes the matter with a warning. A second DUI, a DUI during school hours, a DUI on school property, or a DUI with a student in the vehicle changes the picture completely, and suspension or revocation becomes realistic.
Employment is a separate track. A school district can have its own reporting expectations under its contract and policies, and may learn of the arrest before the Commission does. Read your contract and talk to your union representative early.
Does a DUI Affect a Real Estate License?
The Department of Real Estate has a statutory reporting rule. Under Business and Professions Code Section 10186.2, a licensee must report in writing to the DRE, within 30 days, any conviction of a felony or misdemeanor, including a plea of guilty or no contest, and any felony complaint, information, or indictment. The DRE’s form for this is RE 238. Failure to report is itself a cause for discipline.
A misdemeanor DUI arrest does not have to be reported at the arrest stage. A misdemeanor DUI conviction does. The DRE then reviews the conviction under Section 10177(b) to decide whether it is substantially related to the functions of a real estate licensee. For a first DUI, the DRE’s typical response ranges from no action to a restricted license. Formal revocation is unusual without aggravating facts or a pattern.
Does a DUI Affect a Commercial Driver’s License?
This is the profession where a first DUI has the hardest consequence, and it is written into the Vehicle Code rather than left to a board’s discretion.
Under Vehicle Code Section 15300, a driver is disqualified from operating a commercial motor vehicle for one year after a first conviction for DUI under Section 23152(a), (b), or (c) while operating any motor vehicle. The words “any motor vehicle” matter. A DUI in your personal car on a Saturday night disqualifies your CDL just as a DUI in the truck would. Refusing a chemical test is a separate one-year disqualifier under the same section. If the violation occurred while transporting hazardous materials, the disqualification is three years.
Two more rules apply. In a commercial vehicle, the per se limit is 0.04 percent under Section 23152(d), half the limit for everyone else. And under Section 15302, a second qualifying conviction at any point disqualifies you for life. There is no restricted commercial license during a DUI disqualification. You may be able to drive a personal vehicle on a restricted license. You cannot drive the truck.
For drivers working the Port of Long Beach and the Port of Los Angeles, a one-year disqualification is a one-year loss of income. The DMV hearing and the criminal case both need to be fought on the driving and testing issues, and a wet reckless, if it can be negotiated, does not trigger the Section 15300 disqualification because it is not a conviction under Section 23152.
Why a No Contest Plea, a Wet Reckless, or an Expungement Doesn’t Make This Go Away
A no contest plea is a conviction. Section 490(c) of the Business and Professions Code defines a conviction as a plea or verdict of guilty, or a conviction following a plea of nolo contendere. The Board of Registered Nursing and the DRE both use that same language in their reporting rules. Pleading no contest to avoid admitting guilt in a civil case does nothing for you with a licensing board.
A wet reckless is a conviction. Vehicle Code Section 23103.5 creates a reckless driving conviction with a notation that alcohol was involved. It is a misdemeanor conviction, it must be reported under the same 30-day rules, and it is priorable for DUI purposes for 10 years. Boards generally treat it as less serious than a DUI, and for a CDL holder it avoids the automatic disqualification, so it is often worth pursuing. It is not invisible.
An expungement under Penal Code Section 1203.4 does not erase a conviction for licensing purposes. Section 490(c) says a board may act on a conviction irrespective of a subsequent order under Section 1203.4. Applicants for a new license have more protection after AB 2138, but for a current licensee, the board can still discipline on an expunged DUI. Expungement is still worth doing for employment and other reasons, and our page on DUI expungements explains how it works. It just is not a licensing shield.
Diversion has a similar limit. Business and Professions Code Section 492 states that successful completion of a diversion program under the Penal Code does not prohibit a healing arts board from taking disciplinary action or denying a license for the underlying conduct, even though the arrest record itself is sealed. For a nurse, that means completing military diversion or another diversion program avoids the conviction and the 30-day report, but the Board of Registered Nursing can still review what happened. Section 492 applies to boards under Division 2 of the code, which covers the healing arts. It does not on its face reach the DRE or the Commission on Teacher Credentialing, which have their own rules.

What to Do If You Hold a License and Were Arrested for DUI
Request the DMV hearing within 10 days. Then tell your DUI attorney about the license before the first court appearance. The right resolution for a nurse is often different from the right resolution for a truck driver, and a plea that looks fine on its own can be the wrong plea once the board’s rules are in the room. In some cases the licensing issue calls for a separate licensing defense attorney, and the two should be coordinated rather than run in parallel without talking.
Do not wait to see whether the board finds out. It will. Self-reporting on time is treated as a mitigating factor. A missed report is treated as its own violation.
Frequently Asked Questions: DUI and Professional Licenses
Do I have to report a DUI to the BRN?
Yes. Under 16 CCR Section 1441(c), a registered nurse must report any conviction, including a guilty or no contest plea to a felony or misdemeanor, to the Board of Registered Nursing within 30 days of the conviction. The Board also learns of the arrest from the Department of Justice through your fingerprints, and you must disclose the conviction on your next renewal. Missing the 30-day report is separate unprofessional conduct.
Will a first DUI get my license revoked?
For nurses, teachers, and real estate licensees, revocation for a single misdemeanor DUI with no aggravating facts is uncommon. Boards more often close the file, issue a warning or reprimand, or impose probation. Commercial drivers are different: a first DUI conviction in any vehicle brings a mandatory one-year CDL disqualification under Vehicle Code Section 15300, with no restricted commercial license available.
Does a DUI affect a teaching credential?
It can. The Commission on Teacher Credentialing is notified of the arrest by the DOJ and can open a fitness review under Education Code Section 44242.5. A single misdemeanor DUI unconnected to school usually results in no action or a warning. A second DUI, or any DUI tied to school hours, school property, or students, can lead to suspension or revocation. You must disclose the conviction on your next credential renewal.
Does a wet reckless still have to be reported?
Yes. A wet reckless under Vehicle Code Section 23103.5 is a misdemeanor conviction, and the 30-day reporting rules for nurses and real estate licensees apply to any misdemeanor conviction. Boards tend to treat a wet reckless less seriously than a DUI, and for a CDL holder it avoids the automatic disqualification, but it is not exempt from reporting.
Does an expungement remove a DUI from my licensing record?
No. Business and Professions Code Section 490 lets a board act on a conviction irrespective of a later dismissal under Penal Code Section 1203.4. Expungement helps with employment and lets you answer some questions differently, and it is still worth doing, but a licensing board can consider the underlying conviction when deciding on discipline.
