As you move from a private class license to a CDL your state creates a test and standards around DOT standards... your state can require you to do certain things to get that license but the license meets the standards set forth in FED DOT drivers manual and regulations... these Fed standards are what makes trucks and drivers safe and keeps the standards the same from one state to another.....
As I used my 1 ton PU to pull that 24K lb trailer hauling personal goods... ... my private stuff for fun... race car, atv's ect. . I fell under my states private drivers license and licensing for the truck... . as soon as I used that truck to haul a comerical load than I was required to have an annual inspection, a CDL license that is a combo license (class A w/o air brakes) special plates, permits, with lettering showing our DOT number, company name... all this is spelled out in the FED Guidelines... ...
I took my Class A test in a small 2 axle truck pulling a pintle hitch type trailer... the truck and trailer had air brakes so I could take the air brake portion of the test... . The truck was an old Ford about a 650 with a diesel engine and the trailer had a tandem axle with duals like you'd haul a small track hoe or back hoe on..... I can now drive a truck trailer in my state up to 80K or nationally with one trailer... . if I wish to pull 2 or 3 trailers than I need another endorsement on my license... the max trailer length is 53 ft... .
What I've learned from this is that there is a complete set of rules that govern what happens here... . each state has a group of officers that are commercial officers that know those rules... . and a group of just cops... . when your driving a large rig and the "just a cop" doesn't have a clue what's going on... . he just lets you sit until a "commercial officer" becomes available to stop and check you out... . I've been inspected, weighted along side the road... had my load opened and checked... . I sat once for 4 hours... . for the commercial guy to get the time to come by... do the inspection, look at my log book, my cab cards, insurance... etc... and say..... the other guy was wrong... threre's nothing wrong here... . you can go... .
Cummins724..... if the truck has the correct tags, cab card, hitches, and brakes your class A driver should have been fine... . what his pickup doesn't have is the right stuff to be legal... . a pickup and 2 trailers the way they are delivered won't pass muster... . one example is the ability to apply only the rear trailer brakes, and common ball hitches won't pass... . on a pickup combination the first trailer has to be either a 5th wheel or goose neck and the second trailer can be a ball hitch... . but you need to be able to apply only the rear trailer brakes to straighten the trailers... . and you have to be able to apply the rear trailer brakes, the first trailer brakes and finally the truck brakes in that order... you can't do that with electric or hyd brakes but with special valving in air brake systems thats all done in sequence... ...
I hope that I'm adding good information here..... I'm not trying to add fuel to a fire.....
