I seem to remember something like that here in Kentucky. It's been a while, but I seem to remember it being illegal to drive after a certain time at night. Not sure if that was with my license or just my learner's permit, but rules like this are nothing too uncommon. It's because a lot of kids get their license and have a taste of freedom and want to show off and get hurt, or hurt other people. My sister-in-law totally destroyed her first car, a Camaro that I loved the few times I drove it, because she tried doing 80 around a curve on a hill and she ended up sailing it through the air and sliding into a ditch for about a hundred feet.
