CDL School Bus (S) practice test
Danger zones, loading and unloading, evacuation and the mirror-check routine. 20 questions, every answer explained. Free, no signup.
Drawn from a bank of 47 questions, weighted across every knowledge area. The selection changes daily, but this bank is only 2.4x the test length — so most questions will repeat on a retake. School Bus (S) is a narrow subject and we would rather say that than pad the bank with reworded duplicates.
What this test covers
Federal law prescribes the knowledge areas a CDL applicant must be tested on. This bank is organized by them, and each practice test draws proportionally across all of them rather than sampling at random.
| Knowledge area | Questions |
|---|---|
| Danger zones & mirrors | 11 |
| Loading & unloading students | 12 |
| Railroad crossings | 7 |
| Evacuation & emergencies | 9 |
| Student management & rules | 8 |
Common questions
How many questions are on the real School Bus (S) test?
Test length is set by your state within the federal framework, so it varies — commonly around 50 for General Knowledge. What doesn't vary is the passing score: 80%, federally, everywhere. Confirm the question count with your state licensing agency.
Who has to take the School Bus (S) test?
School bus drivers (also requires the P endorsement).
Can I retake it if I fail?
Most states allow retakes, often after a short waiting period. Check with your state licensing agency.
Are these the real test questions?
No. The federal question pool isn't public, states develop their own wording from it, and versions rotate. These are original questions covering the same federally required knowledge areas — which is what the real test is built from too.
When you want an exam that changes every time
This test rotates once a day, so everyone sees the same set until midnight. The full CDL simulated exam draws a fresh 50-question exam on demand, and the missed-question drill pulls your wrong answers from every CDL test into one place. One payment of $29 covers both, plus every state's car-permit exam.
