Orange County Fourth DUI Lawyer

Facing a Fourth DUI in Orange County? Let Us Help.

If you've been arrested for a fourth DUI in Orange County, you may be facing the most serious DUI penalties you've encountered, including possible felony charges.

Once you've gone through the DUI process, you know how disruptive an arrest can be. Adding the possibility of a felony conviction and prison time can make the situation even more frightening, especially when your job and family depend on you.

Under California law, a fourth DUI involving three qualifying prior DUI-related convictions within 10 years can be prosecuted as a felony. A conviction may result in state prison, substantial fines, license revocation, and long-term consequences for employment and professional licensing.

However, a fourth DUI is a wobbler, meaning misdemeanor treatment may be available.

What Counts as a Fourth DUI in California?

A fourth DUI charge involves a current DUI offense and three qualifying prior DUI-related convictions within California's 10-year lookback period.

California measures the 10-year lookback period by the dates of the qualifying DUI offenses, not the dates the convictions were entered. A prior conviction may not qualify for fourth-offense penalties if the underlying offense occurred outside the statutory period.

Qualifying offenses may include:

• California DUI convictions under Vehicle Code § 23152 or § 23153
• Wet reckless convictions under Vehicle Code § 23103.5
• Certain substantially similar out-of-state DUI convictions
• Qualifying prior felony DUI convictions

Not every prior conviction qualifies. For example, a driver arrested for DUI in Anaheim may have three previous DUI convictions, but one may fall outside the applicable 10-year period.

If prosecutors cannot establish three qualifying prior convictions, they may be unable to pursue fourth-offense penalties under Vehicle Code § 23550.

Is a Fourth DUI a Felony in California?

Sometimes. A fourth DUI can be charged as a felony, but misdemeanor treatment may be available under California law.

The prosecution's charging decision and the court's sentencing options depend on the facts, applicable law, and the defendant's prior record. 

Your attorney should examine whether the prior convictions qualify and whether the circumstances support a request for misdemeanor treatment.

Potential Consequences of a Fourth DUI in Orange County

Actual consequences depend on the charge, prior convictions, sentencing provisions, and other circumstances.

What are the Penalties for a Fourth DUI in Orange County?

A fourth DUI prosecuted as a felony under Vehicle Code § 23550 can carry 16 months, two years, or three years of incarceration under the applicable felony sentencing provisions. If the offense is treated as a misdemeanor, county jail penalties may apply instead.

The conviction can also result in substantial fines and assessments, license revocation, mandatory DUI education, and restrictions on driving privileges. A felony conviction may impose additional consequences, including firearm restrictions and difficulties with employment or professional licensing.

Will I Go to Prison for a Fourth DUI in California?

Not necessarily. Although a fourth DUI can result in a prison sentence, the outcome depends on the charge, criminal history, and evidence.

Depending on the circumstances, probation, misdemeanor treatment, or other authorized alternatives may be available.

For example, if prosecutors cannot establish a qualifying prior conviction, the defense may be able to challenge the fourth-offense enhancement.

Can a Fourth DUI Be Reduced to a Misdemeanor?

Yes. A fourth DUI is a California wobbler, meaning felony and misdemeanor treatment may be available. California Penal Code § 17(b) provides procedures for reducing qualifying felony wobblers to misdemeanors.

Effective January 1, 2026, California expanded courts' authority to consider certain felony-to-misdemeanor reductions before trial.

An attorney may request misdemeanor treatment based on the offense's circumstances, the defendant's history, mitigating evidence, and other legally relevant factors.

A reduction remains discretionary under the applicable provisions.

Can Challenging Prior Convictions Reduce a Fourth DUI Charge?

Yes. Prosecutors must establish three qualifying prior DUI-related convictions within California's statutory lookback period to pursue fourth-offense penalties under Vehicle Code § 23550.

An attorney may examine whether:

• The convictions fall within the 10-year period
• The prior offenses qualify under California law
• Out-of-state convictions satisfy the statutory requirements
• Court records establish the convictions
• Legal defects affect the prosecution's reliance on a prior offense

If one or more prior convictions cannot be used, the prosecution may be unable to establish the fourth-offense allegation. 

Can a Fourth DUI Be Dismissed?

Yes. A fourth DUI charge may be dismissed if prosecutors cannot prove the current DUI offense or if critical evidence is excluded.

Your attorney may challenge whether police had a lawful reason for the traffic stop, whether breath or blood testing was reliable, and whether the prosecution can establish impairment or a prohibited BAC at the time of driving.

A fourth DUI case also requires proof of qualifying prior convictions to support fourth-offense penalties. If prosecutors cannot establish those convictions, the enhanced charge may fail even if the underlying DUI allegation remains.

Will I Lose My Driver's License After a Fourth DUI in Orange County?

A fourth DUI can result in a lengthy driver's license revocation, even if your criminal case is still pending. California's DMV process is separate from the criminal prosecution, and the two proceedings can have different outcomes.

For qualifying alcohol-related DUI arrests, you typically have just 10 days to request a DMV Administrative Per Se (APS) hearing. Missing that deadline can mean losing your opportunity to contest the administrative action through a timely hearing request.

Depending on your circumstances, you may eventually qualify for restricted driving privileges. Reinstatement or restriction requirements can include an ignition interlock device (IID), proof of financial responsibility through SR-22 insurance, DUI education, and applicable DMV fees.

An Orange County fourth DUI lawyer can help you understand the deadlines and licensing consequences while defending the criminal charges.

• California DMV: The DMV provides information about DUI-related license suspensions and revocations, Administrative Per Se hearings, ignition interlock devices, and reinstatement requirements.
