The answer should be no. In California if you have one prior DUI conviction within the past ten years then you will be treated as a Second Offender and face more serious punishment than if you were a first offender. If you have two prior convictions within ten years then your sentence would be a minimum of 120 days in jail plus a 3 year revocation of your driving privilege. However, since your conviction is more than ten years old it is not required to be used to increase your punishment.
This does not mean that the DA will not know about it because they will know about it. Some DA’s will not want to treat you as a “first offender” and might not offer you the best possible offer due to your prior conviction.
