First DUI Penalties in California (2026)
Complete guide to what happens when you get your first DUI in California — jail time, fines, license suspension, and what you can do about it.
Understanding First-Offense DUI in California
A first-offense DUI in California is classified as a Misdemeanor. While this is the least severe DUI charge, the consequences are still significant and can affect your life for years. California uses a 10-year lookback period, meaning any subsequent DUI within that window will be treated as a repeat offense with harsher penalties.
California has a 10-year lookback period for DUI offenses. IID is mandatory statewide for all DUI convictions. Expungement is available after completing probation. The BAC (Blood Alcohol Concentration) limit in California is 0.08% for standard drivers, 0.04% for commercial drivers, and 0.01% for drivers under 21. Being at or above these limits creates a "per se" DUI charge — the prosecution does not need to prove impairment.

What Happens After a First DUI Arrest in California
After being arrested for a first DUI in California, you will face two separate proceedings: a criminal court case and an administrative license suspension through the DMV. California has implied consent laws, meaning you automatically consent to chemical testing by driving on state roads. Refusing a test triggers additional penalties.
The criminal case will determine whether you are convicted and what sentence you receive. Meanwhile, the DMV will independently suspend your license. In many cases, you have only 10 to 30 days to request a DMV hearing to challenge the suspension. Missing this deadline means an automatic suspension.
How a DUI Attorney Can Help
An experienced DUI attorney in California can challenge the traffic stop, question the accuracy of breath or blood tests, negotiate reduced charges (such as a "wet reckless"), protect your driving privileges, and minimize the long-term impact on your record. Attorney fees for a first DUI typically range from $2,000 to $5,000, but the savings in reduced penalties and protected employment can be far greater.
In California, a first DUI may be eligible for expungement After probation completion. An attorney can advise you on the specific requirements and timeline.
