a driving test, no matter how old or young we are.
When I lived in Kansas, and I needed to renew my license, they sent a test and the answers to me. I generally took the test while standing in line at the DMV. What I loved most was that I was reminded of the basic rules of the road/driving which helped me remember that things I needed to know to be a decent driver.
It should always be that way. Passing the driving test at the earliest age possible should NOT be a permanent pass on knowing the rules of the road. We should all need to pass driving stuff, no matter how old we are. I'm currently 75, and I don't think I needed to actually pass any kind of test when I got my license here in this state some 15 years ago. I do know that in a year or so I will need to renew my license every year, but I'm not sure what is required other than (maybe?) a vision test. It really ought to be more than that. We should all go through the same basic tests that a brand new driver goes through. And if we can't pass them, oh gosh, too bad, we can no longer drive.
My older brother was in the process of going blind, and I don't know what the licensing thing was in his state, but I do know that he kept on having many fender benders, because he couldn't see very well. He continued driving years after he should have. If his state had had a thing where a driver had to show up and pass a vision test, he'd have been denied a license years earlier.
I am 75 years old and still drive. I can tell that I'm not as good a driver as I used to be. I am honestly looking forward to not driving, but that will depend on moving into some kind of independent/assisted living place, which I honestly expect to happen by the time I'm 80.
