If you’re facing a 4th DUI in California, you’re up against one of the most serious DUI offenses recognized under state law. In California, a fourth DUI conviction within a ten-year span is treated as a felony, exposing you to potential prison time, steep fines, and an extended driver’s license suspension. While the exact penalties hinge on whether the charge proceeds as a misdemeanor or felony, both carry significant consequences.
At Scott Henry: Criminal & DUI Defense, we understand the complexities of repeat DUI charges. With years of focused experience, we are committed to protecting your rights and building a strong defense strategy tailored to your circumstances.

When Does a DUI Become a Felony in CA?
Under California law, a DUI is typically a misdemeanor. However, a fourth DUI within a ten-year timeframe triggers felony treatment.
According to California Vehicle Code Section 23550, a DUI becomes a felony when the defendant has three or more prior DUI or wet reckless convictions within the past decade.
This includes convictions from other states. Once the fourth arrest occurs, prosecutors will pursue felony charges, with significant prosecutorial discretion depending on aggravating factors such as high BAC, accidents, or refusal to comply with testing.
DUI Limits in California
Understanding California’s legal alcohol limits is critical. These are the thresholds used to initiate prosecution:
- 0.08% BAC for drivers age 21 and older
- 0.04% BAC for commercial license holders
- 0.01% BAC for drivers under 21 or those on DUI probation
However, you may still face arrest and DUI charges even if your BAC is technically under the legal limit. Officers don’t rely on numbers alone, they watch for signs like lane drifting, slurred speech, or the smell of alcohol. Even legal medications or fatigue can be misinterpreted. We scrutinize every step of the stop to ensure your rights weren’t violated.
Consequences of a Fourth DUI Offense
A fourth DUI conviction marks a pivotal shift in how the court views the defendant. At this stage, penalties are no longer about deterrence, they are punitive and long-term.
Key legal consequences include:
- 16 months to 3 years in state prison
- Four-year license revocation with limited or no options for restricted privileges
- Significant fines and penalties often exceeding $18,000
- Mandatory 30-month DUI education program
- Installation of an ignition interlock device (IID) at the defendant’s expense
- Classification as a Habitual Traffic Offender
These penalties can significantly impact your ability to maintain employment, financial stability, and family responsibilities.
Penalties for a Fifth DUI in California
While the fourth DUI presents harsh consequences, a fifth conviction compounds those risks even further.
A fifth DUI is prosecuted as a felony without exception and carries the presumption of a lengthy prison sentence. Common penalties include:
- Up to 4 years in state prison
- Permanent driver’s license revocation
- Long-term DUI rehabilitation requirements
- Substantial fines and long-term probation restrictions
The court will view a fifth DUI as a sign of persistent risk to public safety, and opportunities for leniency become extremely limited.
Legal Strategies to Fight a Fourth DUI Charge
A fourth DUI charge is serious, but there are still ways to fight back. We focus on the details that could change the outcome of your case.
Disputing Prior Convictions
If any of your past DUI convictions were mishandled, like missing legal counsel or improper advisement, we work to challenge them. Tossing out even one could help reduce your current charge.
Contesting the Traffic Stop or Chemical Test
Officers must follow the rules when stopping a driver or collecting a breath or blood sample. If they didn’t have legal grounds for the stop or mishandled the test, we will work to get that evidence thrown out.
Negotiating Alternative Sentencing
We often advocate for options like treatment programs, house arrest, or community service in place of jail. Courts may agree, especially when clients genuinely try to turn things around.
Pursuing Charge Reductions
Not every DUI case holds up under scrutiny. If the evidence is weak or the prosecution’s case is inconsistent, we may push for a lesser charge, such as a “wet reckless.” These outcomes are rare but possible with the right strategy and preparation tailored to your case.
