What Happens In A First Offense DUI Case?

First offense DUIs are not to be taken lightly. A first offense, even with a clean criminal background, is a life-altering event. In California, a DUI accusation typically results in two (2) DUI charges. Typically, these charges are referred to as the “a” and “b” counts, based on the DUI statutes: California Vehicle Code section 23152(a) and (b).

CVC 23152(a)

The “a” count is the general offense of driving under the influence. It is a misconception that a person cannot be convicted of DUI if their blood-alcohol concentration (BAC) is under .08 percent. CVC 23152(a) allows a person to be prosecuted for DUI if they drove a motor vehicle with alcohol in their system, and the alcohol affected their motor skills to the level of measurable impairment.

The prosecutor must prove two elements in order to obtain a conviction under 23152(a): (1) You drove a motor vehicle; and (2) you were “under the influence” of alcohol at the time of driving.

In order to determine whether you were “under the influence,” the prosecution will rely on evidence and observations collected by the arresting officer. This includes performance on field sobriety tests, observations of balance and gait, odors of alcohol, and slurred speech.

CVC 23152(b)

The “b” count applies to blood-alcohol and your actual BAC level at the time of driving. If you drive with a BAC of .08 percent or higher, you can be found guilty of per se DUI under CVC 23152(b).

Because California separates DUI into two offenses, it is possible to have a BAC less than .08 percent and still be convicted of DUI under CVC 23152(a). For these reasons, it is important to speak with an experienced attorney who understands these distinctions, has the ability to navigate both charges and handle your case properly.

What Are The Penalties For A First Offense DUI?

Typically, a first offense DUI is prosecuted as a misdemeanor offense. In San Diego, the penalties include:

  • Up to one year in county jail
  • Informal probation for three to five years

  • A three-to-nine-month DUI program
  • A six-month to one-year driver’s license suspension
  • Installation of an ignition interlock device for up to three years

However, if the court finds that aggravating factors are involved, additional penalties may be imposed. Aggravating factors may include:

  • High blood-alcohol levels of .15 percent or higher
  • Speeding or reckless driving
  • Presence of children in the vehicle
  • Occurrence of an auto accident
