My son, who's 19 now, got his DL as soon as possible. If I remember right, he drug his feet getting his permit until 15.5, so he had to have that 365 days to take driving test. Funny thing, I took him on day 365, and they lady told us, "It has to be 366; lets see if computer flags it." computer did not flag it, and he got it first try.
He had been driving things with motors for a good while; from my old Kubota
L285, his 100 CC mini bike, and our Honda SxS.
My middle kid, just turned 14 a two months ago, and she seems to have a general lack of caring about driving. We told her, your Getting a permit at 15, and a DL at 16; not a choice.
Youngest is 11 now; and she's been driving cars for atleast 2 years now, at her friend's house, they had an old PT Crusier they would drive around the yard. She's also drive the SxS some, and even my Ram on some dirt roads, but with adult supervision.
