Difference between NON-PRO and PRO license?

[dr. d]

if you derive your income directly from your driving, then you are a pro.
if you regularly drive a commercial vehicle, then you are a pro, unless you can convince the authorities otherwise.
of course, some motor vehicles openly suggest you are a pro, simply because you are driving such vehicle.
and unless you work in the boondocks, i don't think you can convince the authorities, that your daily drive to your office is a 6 x 6..
heh heh.
