haven't been paid

Let me research that a little bit more. You may be correct. I myself have trained people while under load before, however it was not a "for hire" carrier.

 

It is my understanding that a permit only allows for instruction. It does not allow for someone to be hauling paying freight. The guiding Federal Law is 383.25 but I do not have a copy of it right now and, (and this is something I hate to say) I could be wrong.

 

You can be paid while training with a permit. The truck just runs as a solo/super solo. Completely legal.

 

Close but no cigar, a student driver with a learners permit can pull a loaded trailer all they want to, just can not get paid to pull it. We used loaded trailer all the time once the student progressed to a point where we felt they could handle it. Again laws in all states are different, I've been told learners permites are no good if you cross state lines but never had a reason to worry about that one.

Note I said loaded, nothing about freight, we used loads of salt or concrete barriers, anything for weight except freight.

 

Wooly, I highlighted and searched that code.
It didn't indicate anything about not being under load, except to indicate a HAZ-mat restriction.
