Aggravated DUI Attorney in Rancho Cucamonga

Over 25 Years Defending DUI Charges in San Bernardino County

An aggravated DUI isn’t a separate crime. It’s a standard DUI charge with one or more aggravating factors that trigger enhanced penalties under California law. Those enhancements can mean mandatory jail time, longer license suspensions, and consequences that can follow you for a decade. At Brian Skibby Law Office APC, we’ve been defending clients in Rancho Cucamonga against serious criminal charges since 1996, and we know how San Bernardino County prosecutors approach these cases.

Aggravated DUI cases are prosecuted in the San Bernardino County Superior Court, Rancho Cucamonga District. Early legal intervention matters on two fronts at once: the criminal charge and the parallel DMV administrative process. The sooner we’re involved, the more options we can pursue on your behalf.

What Makes a DUI “Aggravated” Under California Law

California Vehicle Code Section 23578 authorizes sentence enhancements when a driver’s blood alcohol concentration (BAC) is 0.15% or higher at the time of arrest. That single factor can increase penalties on an otherwise standard first-offense DUI. Several other circumstances carry similar weight with prosecutors and the court.

The following factors can elevate a DUI to aggravated status:

• High BAC (0.15% or above) under VC 23578
• Passenger under age 14, which triggers mandatory additional jail time under VC 23572 and may support separate child endangerment charges under Penal Code Section 273a
• Injury to another person, which may result in felony charges under VC 23153
• Excessive speed, defined as 20 mph or more over the limit on surface streets or 30 mph or more on a freeway
• Prior DUI convictions within the past 10 years
• Driving on a suspended license resulting from a prior DUI
• Chemical test refusal, which triggers enhanced license suspension under California’s implied consent law and is itself treated as an aggravating factor

Whether a charge is filed as a misdemeanor or a felony depends on the combination of factors present and your prior conviction history. A fourth DUI conviction within 10 years is typically charged as a felony.

Potential Penalties for an Aggravated DUI in Rancho Cucamonga

The penalty range expands significantly beyond a standard first-offense DUI. Depending on the aggravating factors involved, criminal penalties can include mandatory jail time, substantially higher fines, extended probation, DUI education programs lasting up to 30 months, and mandatory ignition interlock device installation on any vehicle you drive.

When injury is involved, the stakes are higher still. A DUI causing injury charged as a felony under VC 23153 can carry up to three years in state prison for the base offense, plus one additional year per injured victim. A great bodily injury enhancement under Penal Code Section 12022.7 can add three to six years on top of that.

Separate from the criminal case, the California DMV initiates an administrative action that can result in immediate license suspension. You have only 10 days from the date of arrest to request a DMV administrative hearing to contest this suspension. Missing that deadline means the suspension takes effect automatically.

A DUI conviction also stays on your driving record for 10 years, counting as a prior offense for any subsequent DUI during that period. Collateral effects can include higher auto insurance premiums, restrictions on professional licenses in fields such as nursing or commercial driving, and impacts on employment and housing background checks.

How We Defend Aggravated DUI Cases

Defending an aggravated DUI in Rancho Cucamonga runs on two parallel tracks from the start: contesting the criminal charge in San Bernardino County Superior Court and requesting a DMV administrative hearing within the 10-day window to challenge automatic license suspension. Both require immediate attention, and we handle both.

Our attorneys have tried hundreds of criminal cases and maintain working relationships with local judges and prosecutors built over more than 25 years. That familiarity with how the Rancho Cucamonga District operates informs every stage of our defense strategy.

Defense approaches we may pursue include:

• Challenging the initial stop to determine whether law enforcement had legal justification
• Disputing BAC test results by examining the calibration and handling of testing equipment
• Contesting aggravating factor allegations where the legal basis for enhancements is insufficient
• Identifying procedural errors in police reports and evidence handling
• Negotiating charge reductions or alternative sentencing arrangements where appropriate

Where mitigating circumstances exist, such as voluntary enrollment in alcohol education or treatment programs, employment history, or family circumstances, we present those factors to the court in support of reduced penalties or rehabilitative sentencing options. Throughout this process, you work directly with your attorney. We don’t pass clients to case managers or paralegals.
