California's Vehicle Code Section 23153 says that it is against the law to drive while high on drugs or alcohol. Under California's drunk driving law, the prosecution must prove that the driver's actions directly harmed another person. An intoxicated driver may be charged with felony DUI if these facts are accurate. You need to talk to an experienced Los Angeles criminal defense lawyer who can explain the charges, build a strong case, give you legal options, and help you decide whether to negotiate a settlement or go to trial.
