I just looked. And I guess the laws have changed, because 30 years ago, 15 year olds were welcome to ride mopeds, even on the street.
Have we talked before about the age at which one can get a learner's permit, and that driving/riding before then is illegal? If so, I guess my answer would be different than if we haven't.
That said, my own father taught me to drive at 13 in his parking lot, and we sometimes drove on deserted streets late at night prior to my getting my official license.
No switch (or other CP). We will talk about the law, and the fact that if he'd been caught, he couldn't get his license until he was 18, or even 21, and that had he harmed himself or the bike, it would likely not have been covered by insurance since it was illegal. It doesn't matter if it's a good law or a bad law--it is still THE law.
