How Does Your Driving Rate?
GMAC has a 20 question test to measure a driver's knowledge. It's similar to a written driving test you'd take for a license, though I haven't taken one of those in a couple of decades. There's also a list how each state did. Colorado is #15.
So I was rather pleased to have only missed two of twenty. I will apparently be blinded by the highbeams of oncoming traffic and will not pull my car over properly when I have a flat tire. The first one I just didn't know, and the second one I tried to out-think.
