🚌 School Bus (S) — additional North Carolina requirements
Beyond the federal CDL School Bus knowledge + skills test, this state adds its own school-bus driver credential. (Practice here covers the knowledge test only.)
- Administering agency
- North Carolina DMV (School Bus & Traffic Safety); NCAC 19A 03G.0205
- State credential
- North Carolina issues a School Bus Driver's Certificate from NCDMV (in addition to a CDL with (S) school-bus and (P) passenger endorsements); driving a school/activity bus without it is a Class III misdemeanor.
- Renewal / in-service
- The School Bus Driver's Certificate must be renewed every three years; NCDMV policy limits applicants to two training attempts and six testing attempts per calendar year.
- Other prerequisites
- At least six months of driving experience with a full license; sponsorship from a North Carolina school transportation provider; a CDL with (S) and (P) endorsements; and completion of the NCDMV school-bus training course (taught by a DMV Driver Education Program Specialist) with pre-trip, backing and driving skills evaluations.
Languages, fees and rules change — confirm with the official source linked for each state. 待核 / 'To confirm' = not yet confirmed from an official source (shown honestly, never guessed). The 2025 federal English-Language-Proficiency action is roadside out-of-service enforcement, not a state test-language mandate; states set their own written-test languages (Texas and Florida moved to English-only in 2026).
