You can't dump the CDL without getting a regular liscence. He could probably downgrade it to the other version TX now offers. I think they called it a Class B. It is for the avg guy to haul his own stuff without needing to do all the medical crap. Probably have to call DPS and ask them for specifics. I didn't see it online but this is what I was told I needed by the DOT enforcement guys. I had to get mine in VA (TX resident) and they only offer a CDL so that is what I have. Be interesting when I roll it back to TX.
