Protect Your Rights With An Experienced California DUI Defense Attorney
In California, you can face a driving under the influence (DUI) charge if alcohol, drugs or a combination of both impair your ability to operate a vehicle safely. A single decision, often made in a moment without clear judgment, can lead to serious criminal charges that threaten to reshape your entire future.
People make mistakes, but one error in judgment shouldn’t affect the rest of a person’s life. If you’re facing DUI charges, you are likely feeling overwhelmed by the uncertainty and are worrying about your job, your ability to drive and your future. However, a DUI charge is not the same as a conviction, and you don’t have to face these challenges alone.
I am Marc Pelta, a DUI defense lawyer who represents clients throughout San Francisco and the Bay Area. Having worked as a prosecutor before starting my criminal defense practice at Pelta Law, I know how the state builds DUI cases and where it often falls short. I carefully examine every detail to identify opportunities to protect my clients’ rights and pursue positive outcomes.
Understanding DUI Laws In California
Under California Vehicle Code Section 23152, a person can face DUI charges if they drive while impaired by alcohol, drugs or both. Even prescription medications or legal marijuana can lead to a DUI charge if they affect your ability to drive safely.
For alcohol cases, the state measures impairment through blood alcohol concentration (BAC) tests. BAC shows how much alcohol is in your bloodstream at the time of testing. A person may face charges if they meet or exceed the following BAC limits:
- .08% or higher for most drivers
- .04% for commercial vehicle operators
- .01% for drivers under 21 (zero tolerance law)
- .04% for rideshare and passenger transport services
California also follows “per se” laws, which means that these numbers alone are enough to support a DUI charge. The arresting officer does not need additional proof that the defendant’s driving was impaired. A person can also face DUI charges even if their BAC is lower than these limits if the officer observes signs of impairment in their behavior or driving.
Take note that California also has an implied consent law. This means that by driving on state roads, you’ve agreed to chemical testing if law enforcement suspects impairment. Refusing these tests triggers automatic penalties, including a one-year license suspension, separate from any DUI conviction consequences.
Potential Consequences Of A DUI Conviction
A DUI conviction carries serious consequences that can affect your life for years. Immediate penalties can include:
- Fines ranging from $390 to $1,000, plus court costs exceeding $3,000
- Jail time of 48 hours to six months
- Three to five years of probation with regular check-ins
- Mandatory DUI education programs
- License suspension for six months or longer
- Installation of an ignition interlock device
A DUI conviction can also leave lasting challenges in one’s daily life. Their car insurance rates might double or triple, often lasting for years. Others find themselves spending thousands of dollars on alternative transportation during license suspension and paying ongoing probation fees.
The professional impact can be equally severe. Employers often run background checks. If a person works in transportation or needs a professional license, a DUI conviction on their record could limit their career options or even cost them their current job.
Common Defenses For DUI Charges
DUI convictions rely on proper procedures and accurate evidence. Defending against a DUI charge may involve:
- Questioning whether police had legal cause to pull you over in the first place
- Showing that the field sobriety tests weren’t properly conducted
- Proving that breath or blood tests were mishandled or inaccurate
- Demonstrating that your BAC was lower while driving but rose afterward
- Explaining how medical conditions affected your test results
I will make sure to carefully examine every detail of your case, from the initial traffic stop to the final test results, to protect your rights and potentially challenge any evidence against you.
The DUI Legal Process In California
The DUI process involves both the Department of Motor Vehicles (DMV) and court proceedings. Here’s an overview of what typically happens:
- Arrest and booking: Police take fingerprints and photos, usually releasing the defendant within hours.
- California DMV hearing: A person facing DUI charges has 10 days to request this hearing to protect their license.
- Arraignment: This first court appearance includes hearing charges and entering a plea.
- Pretrial: This involves meetings to review evidence and negotiate with prosecutors.
- Trial: If needed, the defendant’s case goes before a judge or jury. This is only if the parties can’t reach a satisfactory agreement during pretrial negotiations.
Most cases are resolved before trial, but being prepared for each stage is crucial. I will work to protect your rights at every step of the DUI defense process, from the DMV hearing through the final resolution of your case.

Answers To Common Questions About California DUI Cases
Will I lose my driver’s license immediately after a San Francisco DUI arrest?
Not necessarily. A DUI arrest in California may trigger two separate cases: your criminal case and a DMV administrative action. You have only 10 days after your arrest to request a DMV hearing if you want to challenge a potential driver’s license suspension.
Because the DMV process moves quickly, it is important to understand your options and meet the applicable deadlines.
How will a Bay Area DUI charge impact my career and professional reputation?
A DUI charge can affect far more than your ability to drive. Depending on your profession, it may influence employment opportunities, professional licensing, security clearances or your reputation at work. For many professionals in San Francisco and the Bay Area, those consequences can be just as concerning as the criminal charges themselves.
As a former prosecutor, I understand what is at stake. I develop defense strategies that address both the criminal case and the practical concerns that can affect your career, your reputation and your future.
This is my first DUI in San Francisco. Am I going to jail?
Not necessarily. A first-time DUI does not automatically result in jail time. The outcome depends on factors such as your BAC, whether anyone was injured, your prior criminal history and the circumstances surrounding your arrest.
Every case is different. Courts consider the specific facts of the arrest, and the available penalties can vary depending on the circumstances.
What happens if I refuse a breathalyzer or blood test during a California DUI stop?
California’s implied consent law imposes additional consequences if you refuse a chemical test following a lawful DUI arrest, including the possibility of a separate DMV driver’s license suspension. A refusal may also become an issue during your criminal case.
However, refusing a test does not automatically determine the outcome of your case. The legality of the traffic stop, arrest and investigation may still affect how the case proceeds.
Should I just plead guilty to get my San Francisco DUI case over with?
Before you plead guilty, you should understand the long-term consequences. A conviction may affect your driver’s license, insurance rates, employment opportunities and professional reputation.
As a former prosecutor, I know how the state evaluates DUI cases and where weaknesses may exist. Before making a decision, it is important to understand your legal options and the potential consequences of a guilty plea.
