Depends on what they're driving. If they're line haul drivers, operating tractor-trailers, they'll have a Class A CDL, and the company most likely requires all of their tractor-trailer drivers to possess a double trailer endorsement, as well. For the regular delivery vans, they won't need a CDL, as they have a GVWR of under 26,000 lbs., except for New York State, which requires a CDL for all commercial use vehicles rated at over 18,000 lbs. In which case, they'd need to possess a Class C CDL.
