If i have a DUI in massachusettes, is it legal for me to drive in southern,, and what is the statute of limitations of DUI in ma

The answer to your question depends on whether or not your DUI is still pending and what state your license is from. You should consult with your attorney to discuss your situation.

imho, the state of Massachusettes can only dictate that you can not drive within the border of it's state. Massachusettes is without power to tell other states what to do. the laws of the state only apply to that state, it is not a federal crime. that being said you probably want to clear up the dui so that no warrant catches you while you are in another state. general sol in many states is two years.
