If you have been charged with a Los Angeles DUI, you have not yet been convicted. If you have been arrested, you have not yet been convicted. It merely means that there is probable cause for officers to believe that you are guilty of driving while under the influence.
For someone to be convicted for a DUI, the prosecutors must prove that the driver was in fact driving beyond a reasonable doubt, and that the driver was intoxicated while driving. The prosecutor must prove both elements, not just one or the other.
This does not mean that you cannot be charged with a DUI, if you weren’t driving. You may still be charged with a DUI if officers have a reason to believe that you were, at some point, driving while under the influence of alcohol or drugs. To better understand this concept, lets consider some examples.
