Is on the Line,
Experience Matters
A first DUI arrest in California can feel like a fixed outcome before the case has even started. The officer writes a report. The DMV begins a license action. The prosecutor files a complaint. A court date appears on the calendar. To many people, it seems as though the system has already decided what happened.
That is not how a DUI case is supposed to work.
A first-time DUI charge in San Diego is an allegation. It is not a conviction. The prosecutor still has to prove the case. The evidence still has to be tested. The officer’s decisions still matter. The chemical test still has to meet legal and scientific standards. In some cases, a first DUI can be dismissed. In others, it may be reduced to a lesser offense such as wet reckless or dry reckless. Sometimes the best result is not a complete dismissal, but a negotiated outcome that avoids the harshest consequences of a DUI conviction.
The Law Office of Joshua R. Bourne represents people charged with DUI and other criminal offenses in San Diego County. Attorney Joshua R. Bourne is a former San Diego prosecutor who founded his criminal defense firm in 2006. His experience on both sides of criminal cases gives him insight into how prosecutors review DUI evidence, what weaknesses may matter, and how a first-time DUI case can be positioned for the best available result.
California DUI cases are commonly charged under Vehicle Code section 23152. Prosecutors often file two separate counts in alcohol-related cases. Vehicle Code section 23152(a) prohibits driving under the influence of alcohol. Vehicle Code section 23152(b) prohibits driving with a blood alcohol concentration of 0.08 percent or higher. Drug DUI allegations may be charged under Vehicle Code section 23152(f), and combined alcohol and drug cases may be charged under Vehicle Code section 23152(g).
These charges may sound straightforward, but each has legal elements that must be proven. The prosecution must show that the accused person drove a vehicle. For an impairment charge, the prosecutor must prove that alcohol, drugs, or a combination impaired the person’s ability to drive with the caution of a sober person under similar circumstances. For a per se alcohol charge, the prosecutor must prove that the driver’s BAC was at or above the legal limit at the relevant time.
That last point is important. A breath or blood test taken after a traffic stop does not always prove what a person’s BAC was when driving. Alcohol absorption, timing, test procedures, calibration issues, medical conditions, and officer observations can all matter.
A first DUI may be defensible even when there is a chemical test. It may also be defensible when the officer claims there were signs of impairment. DUI cases are built from many separate pieces. If one key piece fails, the entire case may change.
A dismissal means the criminal charge is no longer being pursued in court. This can happen for several reasons. The prosecutor may decide not to proceed after reviewing the evidence. A judge may grant a defense motion that removes critical evidence from the case. The prosecution may be unable to prove an essential element. A witness may be unavailable. A constitutional violation may make the case too weak to continue.
Dismissal is different from a reduction. If a case is reduced, the DUI charge is replaced by or resolved through a plea to a different offense. A reduced charge may still carry consequences, but it can be less damaging than a DUI conviction.
Dismissal is also different from winning the DMV hearing. The DMV administrative process and the criminal court case are separate. The DMV focuses on driving privileges. The court focuses on criminal guilt, punishment, and probation terms. A favorable result in one forum can help, but it does not automatically control the other.
No attorney can promise that a first DUI will be dismissed. However, certain issues can create real leverage for dismissal or for a major reduction.
Many DUI cases begin with a traffic stop. The officer may claim the driver was weaving, speeding, drifting, failing to signal, committing an equipment violation, or driving suspiciously late at night. Police do not need proof of DUI to stop a car, but they do need a lawful basis.
If the stop was based on a hunch rather than specific facts, the defense may challenge it. A motion to suppress evidence under Penal Code section 1538.5 can ask the court to exclude evidence obtained after an unlawful stop or detention. If the court grants the motion, the prosecutor may lose the observations, field sobriety test evidence, statements, and chemical test evidence that followed the stop. In some cases, that can lead to dismissal.
The details matter. Dash camera footage, body camera footage, dispatch logs, officer notes, and the exact language in the police report may reveal whether the stated reason for the stop holds up.
A lawful traffic stop does not automatically justify a DUI arrest. The officer must have probable cause to believe the driver was under the influence. Probable cause is usually based on several claimed observations, such as odor of alcohol, red or watery eyes, slurred speech, poor balance, admissions of drinking, driving pattern, and field sobriety test performance.
These observations are not always as strong as they sound. Fatigue, allergies, nervousness, medical conditions, poor lighting, bad footwear, uneven pavement, and confusing instructions can affect how someone appears during a DUI investigation. A person may smell like alcohol without being impaired. A person may admit to one drink without being over the legal limit. A person may decline or struggle with field sobriety tests for reasons unrelated to intoxication.
If the arrest was not supported by probable cause, the defense may seek suppression of evidence. That can significantly weaken the prosecution’s case.
Chemical testing is often treated as the center of a DUI case, but BAC evidence is not immune from challenge. Breath machines must be maintained and calibrated. Officers must follow proper testing procedures. Blood samples must be collected, stored, labeled, transported, and analyzed correctly. Chain of custody matters. Contamination, fermentation, anticoagulant issues, and lab errors can create problems.
Breath testing can also raise timing questions. A person’s BAC may be rising after the stop, especially if drinking occurred shortly before driving. If the test occurred significantly later, the result may not accurately reflect the BAC at the time of driving.
A first DUI case with a borderline BAC, such as a result close to 0.08 percent, may be particularly vulnerable. Even small testing or timing issues can matter. The same is true when there are inconsistent results, delayed testing, medical issues, or a lack of strong driving evidence.
California DUI law requires proof of driving. In many cases, driving is obvious because the officer personally saw the person operate the vehicle. In other cases, the issue is more complicated. The person may have been found parked, asleep, outside the vehicle, or near a disabled car after an accident.
The prosecutor may rely on circumstantial evidence, such as warm engine parts, witness statements, vehicle location, keys, or admissions. The defense may challenge whether that evidence actually proves driving beyond a reasonable doubt. If the prosecutor cannot prove that the accused person drove while impaired or over the limit, the DUI charge may not stand.
Vehicle Code section 23152(a) focuses on impairment, not just drinking. It is not illegal for a person 21 or older to drive after consuming alcohol unless the person is under the influence or has a prohibited BAC. A DUI impairment case can be weak when the driving was normal, the stop was for a minor reason, the field sobriety tests were poorly administered, and the officer’s observations are vague or exaggerated.
This distinction can be important when the BAC evidence is missing, suppressed, delayed, or below 0.08 percent. The prosecutor may still pursue an impairment theory, but the defense may argue that the evidence does not prove the person was unable to drive with the caution of a sober person.
A reduction usually occurs through negotiation. The defense identifies legal, factual, evidentiary, or mitigation issues that make the DUI charge less certain or less appropriate. The prosecutor may then agree to resolve the case as a lesser offense.
The most common DUI-related reductions in California are wet reckless and dry reckless.
Wet reckless is not a separate offense that police arrest someone for at the roadside. It is a negotiated resolution to a DUI case. It is based on reckless driving under Vehicle Code section 23103, with an alcohol-related notation under Vehicle Code section 23103.5.
A wet reckless can be better than a DUI conviction in several ways. It may involve reduced custody exposure, shorter probation, lower fines and fees, and a shorter alcohol education program depending on the case. It can also carry less stigma than a DUI conviction.
However, wet reckless is not consequence-free. It still creates a criminal record. It can still affect insurance. It may still include probation terms. It also counts as a prior DUI-related offense if the person is later arrested for another DUI within the statutory lookback period. That means a future DUI could be punished as a repeat offense.
For many first-time DUI defendants, wet reckless is a meaningful reduction, but it must be evaluated carefully.
Dry reckless is a reckless driving conviction without the alcohol-related notation. It is generally more favorable than wet reckless because it is not treated the same way as a prior DUI-related conviction in a later DUI case. Prosecutors are usually less willing to offer dry reckless unless there are significant problems with the DUI evidence.
Other possible outcomes may include exhibition of speed, traffic infractions, diversion-like negotiated terms in rare circumstances, or dismissal after completion of certain agreed conditions. These outcomes depend heavily on the facts, the prosecutor, the judge, and the strength of the defense.
A first-time DUI is not reviewed in a vacuum. Prosecutors look at risk, proof, and policy. They may be more open to a reduction when the facts are less aggravated and the evidence has weaknesses.
Common factors include:
A reduction is not given simply because it is a first offense. It is usually earned by showing why the DUI charge is harder to prove than it first appears or why a lesser outcome is appropriate under the circumstances.
Some first DUI cases are treated more seriously than others. Vehicle Code section 23578 allows the court to consider certain aggravating factors, including a high BAC of 0.15 percent or more or a refusal to submit to a chemical test. Excessive speed, reckless driving, a collision, a child passenger, or disrespectful behavior during the investigation can also make prosecutors less flexible.
If someone is injured, the case may be charged under Vehicle Code section 23153, which addresses DUI causing injury. That is a different and more serious category than a standard first misdemeanor DUI. Injury cases require a separate defense strategy because the prosecution must address not only impairment or BAC, but also an unlawful act or negligent act that caused injury.
Even when aggravating facts exist, the defense may still have arguments. A high BAC result can be challenged. A refusal allegation can be disputed. An accident does not automatically prove intoxication caused the crash. A careful defense review can still affect the outcome.
The honest answer is that it depends on the evidence. A first DUI may be dismissed if the stop was unlawful, the arrest lacked probable cause, the prosecutor cannot prove driving, chemical test evidence is excluded, or the case is otherwise too weak to prove beyond a reasonable doubt. A first DUI may be reduced if the defense can show weaknesses in proof, mitigating facts, a borderline BAC, procedural problems, or reasons why a DUI conviction is unnecessarily harsh.
The worst approach is to assume that nothing can be done. The second worst approach is to assume that a first DUI will automatically be reduced because the person has no prior record. Neither assumption is reliable.
A DUI case should be investigated. The evidence should be tested. The DMV and court processes should be handled with a coordinated strategy. The goal is to identify every available path toward dismissal, reduction, or a sentence that protects the client’s future as much as possible.
A first DUI arrest in California does not have to define the rest of your life. The charge may be defensible. The facts may support a reduction. The evidence may be weaker than it looks on paper. The sooner you understand your options, the better positioned you may be to protect your license, record, and future.
