Back in 1966 I got a truck drivers license at the military - passed first time after some 5-6 hours practice in a 1944 war time Chevy truck which the US Army didn't want to ship back home after having defeated Herr Hitler.
Since my major "load" was fellow troops standing on the truck body, then I automatically also got a bus license.
Both were administratively converted to civilian status when I left the military in 1967, and they are valid until 2016 when I must pass a medical test in order to keep them for 5 more years.
It's rediculous. I haven't seen a truck or bus from the inside for 35 years. I have no business at the controls of a modern truck or bus today.
Luckily for this country there is no trucking or bus company either, which would hire me without giving me a very substantial training program first.
Anyway, if I bought my own bus, then I could legally drive it fully loaded bus as long as the passengers are non-paying relatives and friends only.
Nope, this was not an invitation for a free ride.
