A first-time DUI charge in California can be a life-altering experience. Many drivers facing their first offense are not hardened criminals—they are often everyday people who made a single mistake. At The Law Offices of Johnson & Johnson in Walnut Creek, CA, we understand the emotional weight and legal uncertainty that comes with a first DUI. Our goal is to help you fully understand the penalties you’re facing and to fight for the best possible outcome in your case.
What Constitutes a First DUI in California?
In California, a DUI (Driving Under the Influence) is typically charged when a driver is found operating a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher. A “first DUI” refers to the first time a person has been charged with this offense within 10 years. Even if no one was harmed and your driving was otherwise safe, the consequences can be significant.
Criminal Penalties for a First DUI in Contra Costa County
While each case is unique, most first-offense DUIs in Contra Costa County carry the following potential criminal penalties:
- Jail Time: Up to six months in county jail, though in many first-time cases, jail time may be converted to probation or alternative sentencing.
- Fines and Fees: Base fines range from $390 to $1,000, but once penalties and assessments are added, total costs often exceed $2,000.
- Probation: Typically three to five years of informal (unsupervised) probation, which comes with strict conditions including avoiding alcohol-related offenses and completing court-ordered programs.
- DUI School: Attendance in a state-approved DUI education program, usually lasting three to nine months, depending on your BAC level at the time of arrest.
License Suspension and DMV Consequences
Separate from the court process, the California Department of Motor Vehicles (DMV) will impose administrative penalties:
- License Suspension: A first DUI generally results in a six-month suspension. If you refuse a chemical test, the suspension can be up to one year.
- Restricted License: In some cases, you may be eligible for a restricted license, provided you install an ignition interlock device (IID) and enroll in DUI school.
- Ignition Interlock Device (IID): As of recent California law, first-time DUI offenders may be required to install an IID for six months, depending on any aggravating factors, allowing them to drive without other restrictions during this time.
Aggravating Factors Can Increase Penalties
Certain circumstances can elevate a first DUI into something much more serious. These include:
- A BAC of 0.15% or higher
- Refusal to submit to a chemical test
- Causing an accident or injury
- Having a minor in the vehicle at the time of arrest
- Excessive speeding while under the influence
If any of these factors are present in your case, enhanced penalties—including longer DUI school, longer license suspension, or mandatory jail time—may apply.
Collateral Consequences of a First DUI
Aside from legal penalties, a DUI conviction can carry lasting consequences that affect your personal and professional life:
- Increased car insurance premiums
- Loss of employment (especially for jobs requiring driving or a clean record)
- Difficulty obtaining professional licenses or security clearances
- Social stigma and personal stress
Why You Shouldn’t Plead Guilty Without Legal Advice
Many first-time offenders believe they have no choice but to plead guilty and accept the penalties. However, there are often defenses available, such as improper traffic stops, flawed breathalyzer results, or procedural error, that can result in reduced charges or even dismissal. An experienced DUI defense attorney can assess the specifics of your case and help you explore every option.
