Class C License
CDL for vehicles under 26,001 lbs that carry 16+ passengers or placarded hazmat. Also the standard non-commercial passenger car license in most states.
Two distinct uses: (1) the commercial Class C requires a P or H endorsement and applies to vans, shuttles, and small hazmat haulers; (2) the standard car/SUV license most drivers hold is also called Class C in non-commercial form.
