If you have been charged with a Los Angeles DUI, it does not mean that you cannot be charged with anything else. Many charges can arise out of one specific incident, resulting in multiple charges against you and multiple cases.
The best way to understand this process is to walk through an example. Dina has been at a friend’s house for a party. At the party she has consumed several alcoholic drinks, and used some methamphetamine with her friends. Dina is also the one that has provided the drugs and the paraphernalia at the party.
When she is driving home, she runs a stop sign. Officers stop her for the traffic violation, and notice a strong odor of alcohol and red watery eyes. In addition, her mannerisms are eradicated and she seems intoxicated. Officers ask Dina to submit to a field sobriety test, which she does and fails. They also ask her to take a blood alcohol test, which she does and is promptly arrested.
