Our municipality has a dump truck with a 25,990 GWVR and it has air brakes. The driver of this truck does not have a CDL
He does not need a CDL. Just because something has air brakes does not mean you need a CDL. It must have a GVWR of 26001 or more first.
The last I knew, drivers of personal motor homes with air brakes do not have any restrictions
Same answer. Personal motor homes are exempt from CDL rules.
