The states meet the standards of the code of federal regulations and then have some of their own standards. Thats where the interstate confusion comes from . Yes if you are driving a vehicle that falls under dot regulation you have to have a
cdl. Oops more than 2 cents.
A lot of misinformation on the internet from the uninformed.
Truck can easily fall under DOT regulations and NOT need a CDL. Needing #'s and med cards at 10k for example but not a CDL until 26k.
