First Time Pulled Over

Well me and my trainer were driving back from Odessa TX. Cruising along when all of a sudden a state trooper is behind us. Pull over and he says he is going to do an inspection. I said sounds good. My trainer had all of the papers ready to hand him should he ask me for them. He checked the whole rig. Didn't find anything. I did exactly what he told me. And when it was over he said " y'all are good to go, I am giving you a citation, a warning, for not having your papers visible when I got to your truck. " I said " thank you stay safe" but idk where I was supposed to keep the papers. If they would have been in the door he still couldn't have seen them because he came on the passenger side. Does any one know if a warning is points on my license? I had everything ready in arms reach.

Regs say "HM shipping papers must be within the driver’s reach with the seat belt on and visible to first responders entering the vehicle."

He wasn't entering the vehicle.
