🎯 Practice for this exam

🚌 School Bus (S) — additional Illinois 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
Illinois Secretary of State, with the Illinois State Board of Education (ISBE)
State credential
Illinois requires a separate School Bus Driver Permit from the Secretary of State (on top of a license with the (S) endorsement), conditioned on an ISBE training course.
Renewal / in-service
The permit is valid one year; renewal requires an annual ISBE refresher classroom course and an annual physical (valid 90 days) including drug testing.
Other prerequisites
Be at least 21; have held a valid license for the three years immediately prior (not revoked/suspended/cancelled/disqualified) with an (S) endorsement; complete an ISBE classroom-training course; and pass an annual physical (valid 90 days) including drug testing.

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).
