The charge of DUI with injury carries much more serious consequences than simple DUI. If the prosecutor charges it as a misdemeanor, you face up to a year in jail (plus the other standard DUI penalties). If the prosecutor charges it as a felony, you face up to 3 years state prison (plus an additional year for each additional person who was injured).
Another possible consequence to felony DUI exists when any of the injured parties is considered seriously hurt. The prosecution may add a "great bodily injury" enhancement. This adds up to three additional years of state prison exposure. Moreover, the "great bodily injury" enhancement makes the DUI offense a strike under California's Three Strikes law.
It is of the utmost importance that those charged with felony DUI or DUI causing injury be represented by an experienced and knowledgeable defense attorney. Often times, in order to understand the full nature of the prosecution’s evidence, additional discovery should be done on the part of your defense team. It is critical in these cases that we begin a thorough investigation as soon after the accident as possible. Typically, we assign a team of investigators and experts to interview witnesses and to conduct an independent toxicology and accident reconstruction analysis.
