Aggravated DUI Attorney in Orange County

Dedicated Defense Against Orange County Aggravated DUI Charges

An aggravated DUI charge carries consequences that go well beyond a standard first offense. Higher fines, longer jail exposure, mandatory programs, and a more aggressive prosecution all come into play.

At The Law Offices of Taylor & Taylor, we’ve built our entire practice around this kind of case. Founded in 1979 by Lawrence Taylor, the nationally recognized “Dean of DUI Attorneys,” we were California’s first law firm to handle DUI defense exclusively. Lawrence Taylor authored Drunk Driving Defense, now in its Ninth Edition, a textbook cited as authority by the U.S. Supreme Court. That foundation shapes how every attorney at our firm approaches an enhanced DUI case today.

What Makes a DUI “Aggravated” in California

California statutes don’t use the phrase “aggravated DUI” directly. Prosecutors and courts apply it informally to any DUI charge that involves one or more factors justifying a harsher sentence. Which factor applies to your case shapes both the charges you face and the defense strategy that makes sense.

Common aggravating factors include:

• High BAC: A blood alcohol concentration of 0.15% or higher can be treated as a special sentencing factor under California law, even on a first offense.
• DUI causing injury: Causing an accident that injures another person while impaired can be charged as either a misdemeanor or a felony, depending on the severity of the injuries and your record.
• Minor passenger: Having a passenger under 14 years old in the vehicle can trigger an enhancement under Vehicle Code § 23572, which adds mandatory jail time.
• Chemical test refusal: Refusing a breath or blood test after a lawful DUI arrest, which the state treats as an implied consent violation, can itself enhance your sentence.
• Suspended license: Driving under the influence while your license is already suspended from a prior DUI can result in additional charges and additional jail time.
• Felony DUI: A fourth offense within 10 years, or any offense when you carry a prior felony DUI conviction, is prosecuted as a felony rather than a misdemeanor.

Penalties When Aggravating Factors Are Present

Once a prosecutor identifies an aggravating factor, the sentencing floor rises. Compared to a standard first-time DUI, an aggravated charge typically brings substantially higher fines, longer jail or state prison exposure, and a lengthier license suspension or revocation. 

Courts routinely impose mandatory alcohol education or treatment programs and probation with strict conditions. Reinstatement of driving privileges often requires an ignition interlock device, which prevents the vehicle from starting without a clean breath sample.

Why Our Credentials Matter for an Enhanced DUI Case

An aggravated DUI turns on two things: the strength of the evidence and the prosecutor’s charging decision. Both are contestable. We’re the only law firm in California with an in-house technical support staff of DUI professionals with backgrounds in law enforcement, blood alcohol analysis, and driver’s license suspensions. When the prosecution’s case rests on a high BAC reading, our team knows where breathalyzer calibration records can break down and how blood samples can be independently retested.

Our attorneys are former prosecutors, including a former Orange County District Attorney and a former Los Angeles Deputy District Attorney, who average more than 20 years of experience each. They know how charging decisions get made and where those decisions can be challenged. We’re also the only law firm approved by the California State Bar to offer continuing legal education to other attorneys, and our work has been featured twice in the American Bar Association Journal.
