Well... you know that here in AR most people have apparently never read the Driver's Manual and just lucked into passing the written test - and the driving part is mostly a joke (here, you drive around the block taking all right turns while never going over 30mph - no parallel parking or any other proof you've "mastered" the art of driving). They need those reminders of what they've never read or forgotten - reminders they'll also ignore.Atlanta suburbs use them the correct way to warn of lane closures and accidents and giving drivetime ETAs. We use them like California where they just say “click it or ticket”. Drives me nuts.
