A DUI with a "hit and run" charge in Vista is serious. There are a number of issues to be addressed that depend on the evidence against you for each charge. The DUI requires proof beyond a reasonable doubt that at the time you were driving you were under the influence of alcohol and/or a drug , or .08 blood alcohol level or more. Drinking after driving can be a defense because it becomes impossible to show what your blood alcohol level was at the time of driving. However, if you were stopped while driving and over a .08 or under the influence, it does not matter whether you drank after the hit and run. Any DUI within 10 years of a prior, offense date to offense date, is a second offense for purposes of sentencing and carries significantly greater penalties than a first offense.
