In certain circumstances if you are convicted of a DUI, you will be required to place the DUI yellow license plates on your vehicle in order to drive. Aside from the inconvenience of re-registering your car with the BMV, the yellow license plates are a scarlet letter that lets other drivers and the police know of your conviction.
Generally, if your conviction is the 1st in any 6 year period, and does not involve a high test, the yellow license plates are optional for the judge to order. For some judges, however, these plates will be required as a condition of driving privileges even on a 1st offense. For those with high test DUIs or multiple convictions, the DUI yellow license plates are generally mandatory.
