🚌 School Bus (S) — additional Ohio 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
- Ohio Department of Education and Workforce (OAC 3301-83-10)
- State credential
- Ohio requires a school-bus driver training certificate under Ohio Administrative Code 3301-83-10, conditioned on holding a CDL with school-bus and passenger endorsements and completing the state preservice program.
- Initial training
- 15 hours minimum
- Renewal / in-service
- A six-year recertification requires 9 hours of classroom instruction before operating a school transportation vehicle.
- Other prerequisites
- Complete at least 15 hours of preservice training — a minimum 4-hour Ohio preservice classroom curriculum (or a department-approved course) plus at least 12 hours of on-the-bus instruction before being assigned to drive with pupils aboard; and hold a CDL with school-bus and passenger endorsements.
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).
