A. No, the weight on the tag is not the weight that determines if you need a CDL. The weight is the GVWR or Gross Vehicle Weight Rating. This weight is determined by the manufacturer of the vehicle or trailer. GVWR and GCWR are normally determined by checking the vehicle manufacture's identification plate, usually located inside of the driver's side door or on the header board or tongue of the trailer.
**For buses, the plate may be located inside of the passenger door or to the left of the driver's seat.
A. Air Brakes do not determine whether or not the vehicle requires a CDL to drive it. Only the GVWR of the vehicle determines that.
