For engineers and surveyors, section 490 is the gate
A California DUI arrest does not mean that the California Board for Professional Engineers, Land Surveyors, and Geologists automatically disciplines a professional engineer or professional land surveyor. For an existing licensee, discipline decisions fall under Business and Professions Code section 490, and that section allows discipline for a conviction only if the crime is substantially related to the licensed profession.
This matters because many engineers and surveyors hear the wrong warning in the first 24 hours after arrest. The warning sounds like this: "DUI equals board discipline," and that is wrong for a California professional engineer or land surveyor under Business and Professions Code section 490.
California professional engineers and land surveyors are regulated by the Board for Professional Engineers, Land Surveyors, and Geologists, but that board is also within the Department of Consumer Affairs. As a result, it cannot treat every DUI conviction as an automatic professional license case, and it has to tie the conviction to the qualifications, functions, or duties of the license under section 490.
Avoid confusing that with the DMV problem. A civil engineer who drives from Sacramento to a grading meeting, or a land surveyor who drives to three field sites in San Diego County in 1 day, can face a work crisis from a driver license suspension before the board ever sends a letter, and the professional license and the driver license are separate problems.
That is the trap.
The work problem starts with the 10 day DMV clock
After a California DUI arrest, you have 10 days from the arrest to request a California DMV administrative hearing. Requesting that hearing also allows the driver to request the DMV discovery packet; the clock is 10 days.
For many professional engineers and land surveyors, the DMV hearing is the first practical career issue because field work depends on driving. A survey crew assignment, a construction observation schedule, or a site inspection route can fall apart if day 31 arrives and the driver license issue was ignored, and although the board may have no immediate discipline file, your employer may still need you to drive on Monday.
The DMV case is not the criminal court case, and a plea later in court does not automatically fix the administrative license track or stop the 10 day DMV deadline. If the DMV hearing is requested, the discovery packet can give the police paperwork early enough to use it in both tracks.
I want the DMV request handled before anyone guesses about the Board for Professional Engineers, Land Surveyors, and Geologists, because a missed 10 day DMV deadline can create the job problem that people wrongly feared from the board on day one. The order matters here.
- Request the California DMV administrative hearing within 10 days from arrest.
- Ask for the DMV discovery packet when the hearing is requested.
- Keep the DMV issue separate from any section 490 board concern.
The pink DS-367 gives 30 days of full California driving
The pink DS-367 issued after a DUI arrest is a full, unrestricted California driver license for the 30 days it covers if your license was valid at arrest, and a chemical test refusal does not change that 30 day status. For those 30 days, the DS-367 is not a work only license.
This point gets misstated constantly. If the DS-367 covers the 30 days after arrest, the problem is not that the paper itself limits you to a commute, a project site, or a survey yard; it does not.
The restriction question belongs to what happens after the 30 day DS-367 period, not to the pink paper itself, and that distinction can matter if your supervisor asks whether you can drive a company truck to a job site in Orange County during the first month after arrest. During the DS-367 period, the answer is tied to the 30 day full license status, assuming the California license was valid at arrest.
A refusal allegation is still serious in the DUI case and the DMV case, but it does not turn the first 30 days of the DS-367 into a restricted license; say that clearly if someone at work is reading the pink paper wrong.
A section 490 conviction includes pleas people overlook
Business and Professions Code section 490 defines a conviction to include a guilty plea, a guilty verdict, and a conviction following a nolo contendere plea. For board purposes, a no contest plea is not a magic shield; section 490 says it counts.
This is why the criminal case has to be shaped before the plea is entered, because a fast plea can create the exact section 490 record the Board for Professional Engineers, Land Surveyors, and Geologists later reviews, even if the sentence in court feels manageable on the day it is imposed. The court result becomes the licensing record.
Section 490 also controls timing. The board may act on a conviction only after the time for appeal has elapsed, the conviction has been affirmed on appeal, or an order granting probation has been made suspending imposition of sentence. That means an arrest by itself is not the same thing as the section 490 conviction trigger.
There is a practical language point here, because if your employer asks about an arrest, you should not describe it as a conviction unless there has been a guilty plea, guilty verdict, or nolo contendere conviction under Business and Professions Code section 490. Words matter.
Substantial relationship is the engineering and surveying fight
For a California professional engineer or professional land surveyor, the board question is not "Was there a DUI?" The section 490 question is whether the conviction is substantially related to the qualifications, functions, or duties of the licensed profession, and that is a proof issue.
The analysis is fact specific. A DUI in a personal vehicle after dinner in Los Angeles is not the same professional record as a DUI tied to a work vehicle, a project site, or conduct that directly touches licensed engineering or surveying duties, and section 490 still requires the substantial relationship link.
No one at the board gets to skip that link just because the word "DUI" appears in the court file, and the Board for Professional Engineers, Land Surveyors, and Geologists has to use the general Department of Consumer Affairs framework in Business and Professions Code section 490. A first DUI is not a special automatic discipline category for this board.
Ignoring the board issue is not the answer. It means the defense record should be built with the right target in mind. Look at the facts of the DUI. Note the absence or presence of any work connection. Record the court disposition. Then apply the section 490 substantial relationship standard. Those are four separate points.
I also separate mitigation from admissions. If there is treatment, education, or a sober driving plan, it should be presented in a way that helps the court and does not hand the board unnecessary statements, because a section 490 record can last longer than the courthouse conversation.
Penal Code section 1203.4 helps later, but not the way many licensees think
Penal Code section 1203.4 can allow dismissal after successful completion of probation, and for employment and background questions, that later dismissal can matter. For an existing professional engineer or land surveyor, it does not erase the section 490 discipline risk.
Business and Professions Code section 490 says a later Penal Code section 1203.4 dismissal does not prevent the Board for Professional Engineers, Land Surveyors, and Geologists from disciplining an existing licensee based on the underlying conviction. That sentence is the correction many licensees need to hear before they plead. Expungement is not a board eraser.
Timing is part of the misunderstanding. Penal Code section 1203.4 belongs after successful completion of probation, not the morning after the DUI arrest, and if the board already has a section 490 issue based on the conviction, the later dismissal does not make that issue disappear for an existing licensee.
That does not make Penal Code section 1203.4 useless. It can still be worth pursuing when the time is right, and it has different value for applicants under Business and Professions Code section 480(c). But a licensed California PE or PLS should not plead today based on the belief that a later 1203.4 dismissal will wipe the board problem away.
Applicants live under section 480, not the same licensee rule
Applicants to the Board for Professional Engineers, Land Surveyors, and Geologists are in a different statute. Business and Professions Code section 480(a) generally permits denial based on a substantially related conviction only if the conviction occurred within the 7 years preceding the application, and that 7 year limit is an applicant rule.
The 7 year applicant limit in section 480(a) does not apply to serious felonies under Penal Code section 1192.7, offenses requiring sex offender registration under Penal Code section 290, or financial crimes for certain fiduciary professions. A standard DUI analysis usually starts elsewhere, but the statutory exceptions still matter because section 480(a) names them, so you should not mix those exceptions into an existing licensee section 490 analysis.
Business and Professions Code section 480(c) gives applicants another protection. A board may not deny an application because of a conviction dismissed under Penal Code sections 1203.4, 1203.4a, 1203.41, 1203.42, or 1203.425, or a comparable dismissal or expungement, and that is not the same rule that applies to an existing licensee under section 490.
Section 480(f) also generally prohibits boards from requiring most applicants to disclose criminal history. A board may request voluntary mitigation information with notice that not providing it will not affect the decision, but that applicant rule should not be copied into an answer for a person who already holds a California professional engineer or land surveyor license.
This distinction comes up with engineers in training, survey applicants, and people moving from application status to full licensure. If the application is pending, section 480 may be the main statute, but if the license already exists, section 490 is the discipline statute.
A wet reckless changes the court record the board sees
Vehicle Code section 23103.5 is California's wet reckless statute. In a DUI negotiation, that statute can matter because it changes the conviction record from a DUI conviction to a reckless driving conviction with an alcohol notation, while the board still applies the right licensing statute.
A wet reckless is not invisibility. Vehicle Code section 23103.5 still creates a conviction, and Business and Professions Code section 490 defines conviction broadly for existing licensees, so the question remains whether the conviction is substantially related to professional engineering or land surveying work.
The value of a Vehicle Code section 23103.5 result is that the board and employer are not looking at the same court record as a DUI conviction, and that can matter in a section 490 substantial relationship argument and in an employment discussion about driving to project sites. It does not cancel the DMV case.
The DMV track must still be defended on its own 10 day clock, and a later reduction in court does not automatically undo every administrative license issue that began with the arrest. That is why the DMV hearing request and the criminal negotiation should be handled as connected decisions, not as two unrelated chores.
If a board accusation is served, the answer deadline is 15 days
If the Board for Professional Engineers, Land Surveyors, and Geologists serves an accusation governed by the Administrative Procedure Act, Government Code section 11506(a) gives the licensee 15 days after service of the accusation to file a Notice of Defense, and that is a real deadline. Count it.
An accusation is different from an arrest, a court date, a DMV notice, or an employer question, and the 15 day Notice of Defense deadline under Government Code section 11506(a) starts after service of the accusation. Avoid treating old arrest paperwork as the same thing.
The work you do before any accusation can still matter. The criminal record is part of it. The DMV record is part of it. So are the facts of the stop. The chemical test evidence also belongs in that file. The final court disposition closes it out. All of those materials can shape a later section 490 dispute. The best board answer usually starts with a careful DUI defense file.
For a California professional engineer or land surveyor, I would keep three files straight from the start: the criminal case, the DMV hearing, and the Board for Professional Engineers, Land Surveyors, and Geologists issue under Business and Professions Code section 490. Mixing them leads to bad decisions, so start with the 10 day DMV deadline.
