Riverside DUI Enhancement Defense Lawyers
We Fight Sentencing Enhancements in San Bernardino, CA
If you have been arrested for driving under the influence (DUI), it is vital to understand how certain factors—known as enhancements—can dramatically increase the severity of your charges and penalties.
DUI enhancements are aggravating circumstances that prosecutors use to justify harsher sentencing. These enhancements can turn what might have been a misdemeanor DUI into a felony offense, and they often carry mandatory jail time, higher fines, longer license suspensions, and other life-altering consequences.
At Greenberg, Greenberg & Kenyon, our attorneys understand how enhancements are applied and how to challenge them. Whether questioning the legality of a traffic stop, the accuracy of a chemical test, or the presence of an alleged enhancement, we fight to protect your rights and minimize the impact on your future.

Common DUI Enhancements in California
Below are the most common DUI enhancements that can impact your case in Riverside:
- Driving with a minor passenger (under 14 years old). This can trigger additional penalties under California Vehicle Code §23572, often including mandatory jail time.
- High blood alcohol content (BAC of 0.15% or higher). A BAC significantly above the legal limit may result in enhanced penalties, including longer DUI education programs and increased jail time.
- Fourth or subsequent DUI within 10 years. This is typically a felony, carrying potential state prison time and long-term license revocation.
- DUI in a highway safety or school zone. Arrests in designated safety zones, such as school crossings or highway construction or maintenance zones, can lead to sentencing enhancements due to the increased risk to public safety, workers, and infrastructure.
- Excessive speed. Driving 20 mph or more over the speed limit on surface streets (or 30+ mph on highways) while intoxicated can add mandatory jail time to your sentence.
- Refusal to submit to a chemical test. Under California’s “implied consent” law, refusing a breath or blood test can increase penalties, including a mandatory license suspension and longer DUI education requirements.
- Prior criminal history. This includes previous DUI convictions or unrelated criminal offenses leading to harsher penalties.
- Causing injury or death. You can be charged with felony DUI or vehicular manslaughter, carrying years of prison time.
How Enhancements Affect Your Riverside DUI Case
DUI enhancements are not minor details. They can significantly elevate the stakes of your case. You could face felony charges, longer incarceration, higher fines, and permanent marks on your criminal record.
Additionally, enhancements often reduce a judge’s flexibility during sentencing and limit plea bargaining options.
