With nearly 1,900 DUI arrests every year, Rancho Cucamonga is one of Southern California’s most active enforcement zones, especially along the 210 Freeway, Foothill Boulevard, and near Victoria Gardens. If you’ve been arrested here, you’re facing a system designed to secure convictions. The San Bernardino County Sheriff and CHP are extremely active, and the local District Attorney prioritizes DUI prosecution.
At Liberty Criminal Defense, Attorney Evan Vargas fights back. With over 20 years of experience, we know how to navigate the West Valley Courthouse. We understand that a DUI conviction in San Bernardino County carries strict penalties, including mandatory IID installation in many cases. Fight for your freedom with a leading Rancho Cucamonga DUI defense attorney.
Evan Vargas has over two decades of experience winning complex cases. He has defended clients against every type of DUI charge, from simple first offenses to felony DUIs with injury. This longevity means he has earned the respect of judges and prosecutors, which can be a decisive factor in plea negotiations.
We have deep experience with the specific personnel at the West Valley Courthouse. We’re familiar with the common flaws in CHP arrest reports in this area and with the breathalyzer models used by local agencies. We know which prosecutors are open to plea bargains and which require a more aggressive trial posture. This local intelligence is invaluable.
We don’t just hold your hand while you plead guilty. We aggressively challenge the evidence before trial. We have successfully argued for case dismissals based on procedural flaws in the arrest report and Fourth Amendment violations. We fight for the best possible outcome every time.
San Bernardino County is known for tougher DUI sentencing compared with its neighbors. Penalties often include license suspension ranging from 30 days to 3 years, mandatory IID installation (as this is a pilot county), and strict probation terms that often include search clauses (Fourth Waiver).
Whether you are charged under 23152(a) for alcohol or 23152(f) for drugs, the consequences are severe. Drug DUIs are becoming more common in Rancho Cucamonga. We challenge the blood tests and the officer’s DRE (Drug Recognition Expert) evaluation, which is often subjective and flawed.
If you have prior DUIs, the penalties quickly increase. A second offense carries a mandatory minimum of 96 hours in jail. We work to convert jail time into alternatives, including house arrest or work release programs to keep you employed and at home.
Most DUI cases in Rancho Cucamonga are heard at the Rancho Cucamonga District Court.

It is difficult in San Bernardino County, as it is a pilot county where IID is standard for keeping driving privileges. However, exemptions exist for medical issues or non-vehicle ownership, which we can explore.
For Rancho Cucamonga arrests, the hearing is handled by the San Bernardino Driver Safety Office on Business Center Drive. We take care of this for you.
Yes, San Bernardino County often allows “Work Release” (Glen Helen). This may involve working weekends, picking up trash, or completing other manual labor tasks instead of sitting in a cell. We advocate for this option.
You or your lawyer must contact the Driver Safety Office within 10 days of arrest. We do this immediately upon being hired to ensure you don’t miss the deadline.
Yes. Breathalyzers have a margin of error. Your defense may be that your actual BAC was below 0.08% at the time of driving, especially if you had just finished drinking.
Yes, typically. You will lose your “good driver” discount and likely see a significant rate increase for at least 3 years. We can refer you to brokers who specialize in SR-22 insurance to find the best rates.
The judge may order you to attend AA meetings (Self-Help) as a condition of release or probation. We can negotiate this requirement away or reduce the number of meetings.
