The whole hypothetical multiple DUI scenario is also a function of state law. Here in Texas the third one is automatically a felony. I was seated on a jury in Fort Worth with the defendant accused of number three. Interestingly enough the officers could not place him driving the vehicle - only intoxicated, keys in hand, in the vicinity. Nonetheless, he pleaded before we deliberated and got a few years in jail. Checking "Felony Conviction" will certainly get the attention of a potential employer.
