Endorsement & Licensing Rules
8 free questions, part of the School Bus (S) Endorsement CDL practice test
The S endorsement rules are fully codified in 49 CFR 383.123, with the school bus definition in 383.5 and the CLP passenger restriction in 383.153. This is the one part of the school-bus category that's pure federal regulation, not AAMVA manual material. ELDT.io's free bank has 8 questions on this subtopic.
Questions about Endorsement & Licensing Rules
What federal regulation covers the school bus (S) endorsement requirements?
Per 49 CFR 383.123, a driver must pass a school-bus-specific knowledge test covering four required topic areas, plus a skills test, on top of whatever CDL class and other endorsements they already hold.
What makes a vehicle a "school bus" for CDL purposes?
Per 49 CFR 383.5, it's a CMV used to transport pre-primary, primary, or secondary students to and from school or school-related events, not just any vehicle that happens to be carrying kids.
Can a CLP holder get the S endorsement before getting a full CDL?
Yes, but per 49 CFR 383.153(b)(2)(viii)(B), a CLP holder with the S endorsement still carries a passenger restriction and can't actually transport students until they hold the full CDL.
