California CDL School Bus Practice Exam 2026

Sit this one like the real appointment. The California school bus endorsement real exam rehearsal runs without hints, without backtracking, and without a second chance at a question, which is exactly how the 2026 California DMV knowledge test for the S endorsement will feel.

Everything is in scope: the danger zones around the bus and the crossover and convex mirrors that cover them, the amber and red light sequence with the stop arm, loading and unloading procedure including student crossing, railroad crossing stops, evacuation decisions and the 100-foot rule, emergency equipment, student management, and the post-trip sweep of every seat.

Because the length of the school bus knowledge exam is a state matter, look it up in your California CDL Manual instead of assuming. The federal number you can rely on is the core CDL general knowledge test: 50 questions with 40 correct required for the 80 percent pass mark. Clear this rehearsal repeatedly and schedule your S endorsement exam with confidence.
