That's because it would require every driver in Illinois, documented or not, to get a license. It means everyone behind the wheel would have driver's ed training and insurance.
Currently, there are about a quarter million illegal immigrants driving in Illinois. They are all unlicensed and have no insurance. They still go out on the roads when they have to, and that's what can lead to crashes.
The licenses would be a little different than we're used to. They'd only be valid in Illinois, and fingerprints must be provided to get one.
In a push to get the idea passed, both sides of the aisle are supporting the plan. Governor Quinn, who's a democrat is for it, as well as former Governor Jim Edgar, who's a republican.
