First Time DUI Defense San Diego | Dod Law Aggressively Defends SoCal DUIs

Facing a first-time DUI in California can be intimidating and overwhelming. Many drivers worry they will lose their license, pay thousands in fines, or even serve jail time. But the truth is, with the right legal defense and knowledge of California’s ignition interlock device (IID) program, you can often keep driving legally — even after a DUI arrest.

At Dod Law, APC, our experienced Southern California DUI defense attorneys help clients minimize the consequences of a first-time DUI. We understand how much your driver’s license means to your job, family, and freedom, and we fight to protect it every step of the way.

Understanding a First-Time Misdemeanor DUI in California | Ignition Interlock Device

A first-time DUI is typically charged as a misdemeanor under California Vehicle Code §23152(a) or §23152(b). These laws prohibit driving under the influence of alcohol or driving with a blood alcohol concentration (BAC) of 0.08% or higher.

A first offense can lead to:

• Up to six months in county jail (though most first-time offenders avoid jail time)
• Fines and penalty assessments totaling $1,500 to $2,000
• A six-month license suspension from the DMV
• Three to five years of probation
• Mandatory DUI education classes
• Possible installation of an ignition interlock device (IID)

While that list can sound intimidating, most first-time offenders in California are eligible for alternatives that allow them to keep driving — including through the IID program.

How the Ignition Interlock Device (IID) Lets You Keep Your License

Thanks to California Senate Bill 1046, which took effect statewide in 2019, many drivers arrested or convicted for DUI can avoid a full license suspension by installing an ignition interlock device (IID) in their vehicle.

An IID is a small breath-testing device wired to your vehicle’s ignition. Before starting your car, you must blow into the device; if it detects alcohol, the engine will not start. It also requires random retests while driving to ensure ongoing sobriety.

For first-time misdemeanor DUI convictions, here’s how the IID option works:

• IID installation period: Usually six months
• No hard license suspension: You can drive anywhere, anytime, as long as the IID is installed
• Immediate eligibility: You can typically install the IID right after your arrest and avoid a period of no driving
• DMV approval: You must use a DMV-certified IID provider and file proof of installation

This means that instead of being stuck without transportation, you can continue driving legally to work, school, and family obligations — provided you comply with the IID requirements.

At Dod Law, we guide our clients through every step of the IID application process to ensure they stay on the road and in compliance with the law.

Avoiding a License Suspension After a DUI Arrest California IID laws

After a DUI arrest, the DMV will automatically begin a license suspension process — separate from your criminal case. This is called an Administrative Per Se (APS) suspension. You only have 10 days from your arrest to request a DMV hearing to challenge the suspension.

This hearing is your first opportunity to fight to keep your license. An experienced DUI attorney can represent you at this hearing, question the arresting officer, challenge the breath or blood test results, and present evidence that the stop or arrest was unlawful.

Dod Law regularly defends clients at DMV hearings and has successfully prevented countless suspensions by uncovering procedural errors, unreliable BAC results, and violations of constitutional rights.

How Dod Law Aggressively Defends First-Time DUI Cases

At Dod Law, APC, we do not treat first-time DUIs as “routine.” We know how devastating a conviction can be — increased insurance costs, career setbacks, and a permanent criminal record. That’s why we approach each case with precision and aggression, focusing on getting charges reduced or dismissed.

Our defense strategies often include:

• Challenging the legality of the traffic stop: If the officer lacked reasonable suspicion or probable cause, we can move to suppress the evidence.
• Questioning chemical test accuracy: Breathalyzers and blood tests must follow strict calibration and procedural standards. Any deviation can make the results inadmissible.
• Examining officer conduct: We review dashcam, bodycam, and field sobriety test procedures to expose inconsistencies or rights violations.
• Negotiating reduced charges: In many first-time DUI cases, we can negotiate for a “wet reckless” or “dry reckless” plea — which can lower fines, shorten probation, and eliminate the need for an IID.

Our goal is always to help you move forward with your life as quickly as possible — keeping your record clean, your license valid, and your reputation intact.
