What is California Vehicle Code CVC 23140?
California Vehicle Code 23140 makes it illegal for anyone under 21 to drive with any measurable alcohol in their system. This is not the same as a standard DUI. The law sets a much lower threshold for underage drivers. Even a small amount of alcohol can trigger this violation. Penalties include fines, license suspension, and mandatory DUI education programs.
Common scenarios
Scenario 1
An 18-year-old driver is stopped at a DUI checkpoint. The officer smells alcohol and administers a PAS test showing a BAC of 0.02%. The driver had one beer at a party two hours earlier. The driver receives a CVC 23140 citation and a one-year license suspension notice.
What to do: Save evidence immediately and compare the cost of paying against fighting by written declaration.
Scenario 2
A 20-year-old is pulled over for speeding. The officer notices the driver is young and asks if they have been drinking. The driver admits to having a glass of wine with dinner. A breath test shows 0.03% BAC. The driver is cited under CVC 23140 and must attend a DUI program.
What to do: Save evidence immediately and compare the cost of paying against fighting by written declaration.
Scenario 3
A 19-year-old uses alcohol-based mouthwash before driving to work. An officer stops the driver for a broken taillight and administers a PAS test, which shows 0.01% BAC. The driver receives a citation even though they did not consume any alcoholic beverages.
What to do: Save evidence immediately and compare the cost of paying against fighting by written declaration.

Detailed guide
California Vehicle Code 23140: Zero Tolerance Underage DUI
What CVC 23140 Means in Plain English
California Vehicle Code Section 23140 is the state's zero tolerance law for drivers under 21 years old. If you are under 21 and drive with a blood alcohol content (BAC) of 0.01% or higher, you can be cited under this code. This is different from a standard DUI charge under CVC 23152, which requires a BAC of 0.08% or higher for drivers 21 and over.
The law exists because California prohibits anyone under 21 from consuming alcohol. The zero tolerance policy means that even trace amounts of alcohol can result in a violation. A single drink, mouthwash, or certain medications can push your BAC above 0.00%.
This is a civil violation, not a criminal charge in most cases. However, it still carries serious consequences that can affect your driving privileges, insurance rates, and future opportunities.
How the Violation Occurs
Law enforcement typically discovers CVC 23140 violations during traffic stops. An officer may stop you for a traffic violation, equipment problem, or DUI checkpoint. If the officer suspects you have been drinking and you are under 21, they will likely ask you to take a preliminary alcohol screening (PAS) test.
Under California's implied consent law, drivers under 21 must submit to chemical testing when lawfully arrested or detained on suspicion of driving with alcohol in their system. Refusing the test can result in a one-year license suspension, even if you were not actually drinking.
The officer will use a breathalyzer or may request a blood test. If your BAC registers at 0.01% or higher, you will likely receive a citation under CVC 23140. The officer will also typically issue an immediate administrative license suspension notice from the DMV.
Penalties and Consequences
Fines and Fees
The base fine for CVC 23140 is typically $100. However, with penalty assessments, court fees, and other charges, the total cost usually ranges from $431 to $469 or more, depending on your county. Some counties add additional fees that can increase the total.
License Suspension
The DMV will suspend your license for one year for a first offense under CVC 23140. This is an administrative action separate from any court proceedings. You have only 10 days from the date of your arrest to request a DMV hearing to contest the suspension. Missing this deadline means the suspension goes into effect automatically.
For a second or subsequent offense within 10 years, the suspension period increases. You may be eligible for a restricted license that allows you to drive to work, school, or a DUI program, but this is not guaranteed.
DUI Education Program
You may be required to complete an alcohol education or DUI program. The length and type of program depend on your specific case and whether this is a first or repeat offense. These programs typically cost several hundred dollars and require multiple sessions over weeks or months.
DMV Points
CVC 23140 violations typically result in 2 points on your DMV driving record. These points remain on your record for 10 years for DMV purposes, though they affect your negligent operator count for only 3 years. Accumulating too many points can lead to additional license suspension as a negligent operator.
Insurance Impact
An underage DUI violation will almost certainly increase your insurance rates significantly. Insurance companies view any alcohol-related driving offense as high-risk behavior. Your rates may double or triple, and some insurers may cancel your policy entirely. These increased rates typically last for at least three years.
Criminal vs. Civil Consequences
CVC 23140 itself is typically handled as a civil matter. However, if your BAC was 0.05% or higher, you may face additional criminal charges under CVC 23152 or 23153. If there was an accident, injury, or other aggravating factors, criminal charges become more likely.
What to Check on Your Citation
When you receive a CVC 23140 citation, examine it carefully for the following information:
Your age at the time of the offense. The violation only applies if you were under 21. If the officer made an error about your age, this is a complete defense.
The BAC level recorded. The citation should indicate what your blood alcohol content measured. If it was below 0.01%, you should not have been cited under this code.
The date and time of the stop. Make sure these are accurate. Errors can sometimes help your defense.
The location of the stop. Note exactly where the officer stopped you. This may be relevant to whether the stop was legal.
The reason for the stop. The officer must have had legal justification to stop you. This should be noted somewhere in the police report or citation.
Your court date and deadline. You typically have a specific date by which you must respond. Missing this deadline can result in additional penalties, including a license suspension and possible warrant.
The DMV hearing deadline. You have only 10 days to request a DMV hearing. This deadline is separate from your court date and is critically important.
Evidence to Gather
Building a strong defense requires collecting evidence as soon as possible after the citation:
Photographs of the stop location. Take pictures of where you were stopped, including traffic signs, lighting conditions, and road layout.
Witness statements. If anyone was with you or saw the stop, get their contact information and written statements about what happened.
Receipts and timeline. Document where you were before driving, what you consumed (if anything), and when. Receipts from restaurants, stores, or other locations can help establish your timeline.
Medical records or medication lists. Some medications, health conditions, or even certain foods can affect BAC readings or cause false positives.
Mouthwash or other products. If you used mouthwash, breath spray, or consumed certain foods before driving, document the specific products. Many contain alcohol that can cause a false reading.
Calibration records for the testing device. You or your attorney can request maintenance and calibration records for the breathalyzer used. Poorly maintained devices can give inaccurate readings.
Video evidence. If the stop occurred at a location with security cameras, try to obtain footage. Some police vehicles have dashcams that may have recorded the stop.
Your own notes. Write down everything you remember about the stop while it is fresh in your memory. Include what the officer said, how the test was administered, and any other details.
Your Options Before Paying
Paying the fine is the same as pleading guilty. Before you pay, consider these options:
Request a DMV Hearing
You must request a DMV administrative hearing within 10 days of your arrest. This hearing is separate from your court case and focuses solely on whether your license should be suspended. At the hearing, you can challenge the suspension by questioning the officer and presenting evidence. Requesting a hearing also stays (delays) the suspension until the hearing is completed.
Fight the Citation in Court
You have the right to contest the citation in court. You can plead not guilty and request a trial. During the trial, the prosecution must prove that you were driving, that you were under 21, and that your BAC was 0.01% or higher. You can challenge any of these elements.
Trial by Written Declaration
California allows you to contest many traffic violations through a Trial by Written Declaration. However, CVC 23140 cases may not always be eligible for this option, especially if there are criminal charges involved or if the court requires your appearance. Check with the court listed on your citation to see if this option is available. If it is, you submit a written statement explaining your defense without appearing in court. The officer also submits a written statement, and a judge decides based on the documents.
Negotiate a Reduction
In some cases, it may be possible to negotiate with the prosecutor for a reduction to a lesser charge or alternative penalties. This typically requires appearing in court or having an attorney represent you. The prosecutor may consider factors like your prior record, the specific BAC level, and the circumstances of the stop.
Attend a DUI Program Voluntarily
Sometimes completing a DUI education program before your court date can help demonstrate responsibility and may influence the outcome. However, do not enroll in a program without understanding how it might affect your case. Consult with a legal professional first.
Traffic School Eligibility
CVC 23140 violations are not eligible for traffic school. Traffic school is only available for certain moving violations and cannot be used to mask alcohol-related offenses. Even if you complete a DUI education program, the violation will still appear on your driving record.
When to Seek Legal Advice
CVC 23140 is a serious matter that can have long-term consequences. You should strongly consider consulting with a licensed attorney if:
- Your BAC was 0.05% or higher, which may result in additional criminal charges
- You are facing license suspension and need your license for work or school
- You believe the stop was illegal or the test was inaccurate
- You have prior alcohol-related offenses
- There was an accident or injury involved
- You are under 18 and may face juvenile court proceedings
- You need help navigating both the DMV hearing and court case
ClerkHero may not handle all case types, especially those involving criminal charges, suspended licenses, or complex DUI matters. A licensed DUI attorney can evaluate your specific situation, represent you at the DMV hearing, and defend you in court.
Understanding Your Rights
You have important rights when facing a CVC 23140 violation:
The right to remain silent. You do not have to answer questions beyond providing your license, registration, and insurance. Anything you say can be used against you.
The right to contest the charges. You are presumed innocent and have the right to challenge the evidence against you.
The right to a DMV hearing. You can contest the administrative license suspension separately from the court case.
The right to see the evidence. You can request police reports, calibration records for testing devices, and other evidence through the discovery process.
The right to legal representation. You can hire an attorney to represent you in both the DMV hearing and court proceedings.
Long-Term Impact
A CVC 23140 violation can affect you for years:
Employment. Some employers conduct driving record checks, especially for jobs that involve driving. An underage DUI can affect your job prospects.
Education. Some colleges and universities ask about disciplinary actions and legal violations. A DUI violation may need to be disclosed on applications.
Professional licenses. If you are pursuing a career that requires a professional license (nursing, teaching, law, etc.), an alcohol-related driving offense may complicate the licensing process.
Future DUI offenses. If you are convicted of another DUI offense after turning 21, the CVC 23140 violation may be considered a prior offense, leading to enhanced penalties.
Insurance. The insurance impact can last three to five years or longer, costing you thousands of dollars in increased premiums.
Taking Action
If you have been cited under CVC 23140, time is critical. The 10-day deadline for requesting a DMV hearing comes quickly. Do not wait to take action. Review your citation carefully, gather evidence, and consider your options. Whether you choose to fight the charge, negotiate, or seek legal help, understanding the process and acting promptly gives you the best chance for a favorable outcome.
This is legal information, not legal advice. Every case is different, and the outcome depends on the specific facts and circumstances. Consider consulting with a licensed attorney who can evaluate your individual situation and provide personalized guidance.

Common defenses
Defense ideas to review if written declaration is available
Every ticket is different. These issues can help you organize facts, evidence, and questions before deciding whether to pay, correct the issue, or check eligibility.
Defense 1
The breath test device was not properly calibrated or maintained, leading to an inaccurate BAC reading that should be excluded as evidence.
Defense 2
The BAC reading was caused by mouthwash, medication, or other non-alcoholic sources rather than consumption of alcoholic beverages.
Defense 3
The officer did not have reasonable suspicion or probable cause to stop your vehicle, making the stop illegal and any evidence obtained inadmissible.
Defense 4
You were not actually driving or in physical control of the vehicle at the time the officer observed you, which is a required element of the violation.
Defense 5
The officer did not follow proper procedures when administering the chemical test, such as failing to observe you for the required period before testing.
Defense 6
There were errors in the citation or police report, such as incorrect age, BAC level, or other material facts that undermine the prosecution's case.

Frequently asked questions about CVC 23140
What should I do first after getting a CVC 23140 citation?
Request a DMV hearing within 10 days of your arrest to contest the license suspension. This is your most time-sensitive deadline. Also note your court date, gather evidence such as receipts and witness information, and take photos of the stop location. Write down everything you remember about the stop while the details are fresh. Consider consulting with a DUI attorney who can help with both the DMV hearing and court case.
Can a CVC 23140 violation be reduced or dismissed?
Yes, depending on the specific facts of your case. Common factors that affect outcomes include whether the stop was legal, whether the testing device was properly calibrated, what your actual BAC level was, and whether there is evidence the reading came from non-alcoholic sources. Cases with procedural errors, inaccurate tests, or weak evidence are more likely to be reduced or dismissed. An attorney can evaluate your case and identify the strongest defenses.
What facts matter most for fighting a CVC 23140 charge?
The legality of the traffic stop is critical because without a valid reason to stop you, all evidence may be suppressed. The accuracy and calibration of the testing device matters because faulty equipment can produce false readings. The time between your last drink and the test affects BAC calculations. Whether you used mouthwash, medication, or consumed certain foods can explain a low BAC reading. Witness testimony and video evidence can contradict the officer's version of events. Documentation showing procedural errors strengthens your defense.
Will I definitely lose my license for one year?
Not necessarily. If you request a DMV hearing within 10 days and present a strong defense, you may be able to keep your license or obtain a restricted license. The DMV hearing is separate from court and focuses on whether the suspension is justified. Winning the DMV hearing means keeping your license even if you still face court proceedings. However, if you miss the 10-day deadline or lose the hearing, the one-year suspension will take effect.
More FAQs about CVC 23140
Can I get a restricted license to drive to work or school?
Possibly, but it depends on your specific circumstances and whether you meet certain requirements. Restricted licenses for CVC 23140 violations are not automatically granted. You typically need to enroll in a DUI program and may need to install an ignition interlock device. The DMV will evaluate your situation and determine eligibility. Having an attorney can help you navigate the process and improve your chances of obtaining a restricted license.
How will this affect my insurance rates?
Your insurance rates will almost certainly increase significantly, often doubling or tripling. Insurance companies view any alcohol-related driving offense as high-risk behavior. Some insurers may cancel your policy entirely, forcing you to find coverage through high-risk insurance providers. These increased rates typically last at least three years and can cost you thousands of dollars. Shopping for new insurance after a CVC 23140 violation is difficult and expensive.
Is CVC 23140 a criminal charge or a civil violation?
CVC 23140 is typically handled as a civil violation, not a criminal charge. However, if your BAC was 0.05% or higher, you may face additional criminal DUI charges under CVC 23152. If there was an accident, injury, property damage, or other aggravating factors, criminal charges become more likely. Even as a civil violation, CVC 23140 has serious consequences including license suspension, fines, and long-term impacts on your record and insurance.
What happens if I refuse the breath or blood test?
Refusing a chemical test when you are under 21 results in an automatic one-year license suspension for a first refusal, and longer suspensions for subsequent refusals. This suspension is separate from any suspension for the CVC 23140 violation itself. California's implied consent law requires drivers under 21 to submit to testing when lawfully detained on suspicion of driving with alcohol. Refusal does not prevent you from being charged and may actually make your situation worse.
What is VC 23140?
VC 23140 is another way California courts and citations may refer to CVC 23140 for Under 21 DUI. VC means Vehicle Code, while CVC means California Vehicle Code.
Is VC 23140 the same as CVC 23140?
Yes. On California traffic tickets, VC and CVC can refer to the same California Vehicle Code section. VC23140 is the compact version of VC 23140.
Can I fight a VC 23140 ticket?
You may be able to contest it depending on the facts, evidence, and court process. ClerkHero can help eligible California drivers prepare self-help documents for review.
