The school bus endorsement applies to applicants who wish to drive a school bus in any Class A or B CDL. To add an S endorsement to your CLP/CDL, you must pass the West Virginia school bus test, and you must also pass skills tests in a school bus. The WV CDL bus test consists of 20 questions, and you'll need at least 16 correct answers to pass (80%). The knowledge test covers the following sections of the West Virginia CDL Manual: School Buses, Vehicle Inspection Test, Basic Control Skills Test and Road Test.
