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 North Carolina school bus test, and you must also pass skills tests in a school bus. The NC 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 North Carolina CDL Manual: School Buses, Vehicle Inspection Test, Basic Control Skills Test and Road Test. After studying, take this NC CDL practice test to prepare for the actual bus test!
