OK. Enough is enough. Time for one or all of you to enlighten a cold logical thinking European about some, shall I say "weirdness" in American law and in behavior?
1) How the friggin h*ll do you manage to get a Pete 379 (nice trucks, would love to have one) declassified as a "pick-up"? If you would extend the sleeper to beyond the rear wheels, it would become a sedan or mini-van?
2) Or more general: what is the legal definition of a pick-up?
There are no permanent weigh stations in continental Europe as far as I know. With the traffic density and the prices of real estate, weigh stations would be too expensive to built and creating too much chaos on the roads. We do have very strict weight and dimension laws, but they are checked and enforced by spot-checks.
Most European countries now also have country-wide toll-roads. For trucks its very simple. You need to have a pre-paid and activated electronic pass before entering a highway. Hundreds or thousands of portals across the highway electronically check all trucks when passing, no stopping needed, and I think its quite hard to circumvent. In the USA, since December 2010 the Dallas North Tollway is an example of how this works.
For the rest -think I mentioned this earlier - in Europe vehicles are divided in
person car and trucks. Personal is everything with three or more wheels weighing not more than a GVTW of 7700 Lbs. This goes on a normal driving license. EVERYTHING above 7700 LBS and you need a truck drivers license. If you want to drive professionally, you need additional schooling and tests. Motor cycle is separate as "motorized vehicle with two or three wheels".
