I rode from 1971 to 1973 without a license of any kind. With the helmet law the cops couldn't tell I was under age. Summer 1973 I got my Motorcycle license only. Maryland used to let you get only the motorcycle license without the car license back then. Didn't get my car License until 1974. Took the motorcycle test on a special motorcycle test range inside a cement walled off area. It was designed to test your balance and agility. Very tight course. Had to do cones, circles, figure 8, run through 3 gears, stop and go a few times, all staying on a painted line and not touching the ground. (Except when stopping.) They deducted points if you took your foot off the pegs and failed you if you touched the ground while doing maneuvers. I took that test at 16 the in summer 1973 on a '72 Honda CL 350. Passed on the first try.
