California CDL School Bus Practice Test 1: what to expect and what trips drivers up
This is the main California school bus endorsement test rehearsal for 2026, free to run and open without an account. Drivers looking for a cdl school bus practice test, a school bus driver test, or simply a school bus practice test that matches what California actually asks should start right here.
Coverage runs the entire S endorsement syllabus: danger zones and the mirror system that covers them, loading and unloading procedure, the amber-then-red light sequence and the stop arm, railroad crossing procedure, emergency evacuation decisions, student management, post-trip checks for sleeping or hiding children, and the bus-specific items in your pre-trip inspection.
The S endorsement sits on top of a commercial license and usually pairs with the P passenger endorsement, so plan on both. The school bus knowledge exam length is set by the state - check your California CDL Manual for the exact number of questions. The one figure that never changes is the general knowledge written test: 50 questions, 80 percent to pass, 40 correct answers.
Every question traces back to the California CDL Manual - skim the right-of-way and signs chapters before your retake.
