I'd take it one step further. A person with two DUI convictions should never be issued a driver's license again.

My wife used to work at the Maryland Department of Motor Vehicles - she regularly saw driving records with 10 or more DUI's on them. The drivers had not had licenses for years, but kept driving anyway.

I am just not sure about this approach. The "scarlet letter" concept has some merit, but using it as automatic probable cause for a traffic stop bothers me.
