What is the Difference Between a DUI and a DWI?

This is a very common question and can be answered very succinctly.  The difference between the two is just in wording or semantics.  A DUI is a Driving under the Influence.  A DWI is a driving while intoxicated.  Both terms equate to the same thing which is the crime in California of driving while impaired or Vehicle Code section 23152(a).
