About

Pass your CDL School Bus (S) endorsement — first try. Real DMV exam format: 20 questions, 25 minutes, 80% to pass. 500+ practice questions from the 2026 CDL handbook. Study offline. CDL School Bus Test 2026 is built for one job: get you the School Bus (S) endorsement. Not a generic truck-driver app with a buried school-bus chapter. Every lesson, mock exam, and explanation is S-endorsement material — danger zones, mirrors, loading and unloading, railroad crossings, evacuation, post-trip inspection, ABS, and student management. THE REAL TEST, NOT A TRIVIA QUIZ The written School Bus exam is typically 20 multiple-choice questions. You need 16 correct (80%) in about 25 minutes. Our mock exam uses that same format so test day feels familiar. WHAT YOU WILL PRACTICE • Danger zones and mirrors — 30 feet in front, 10 feet on the sides, the 400-foot rear blind spot, convex vs. flat vs. crossover mirrors • Loading and unloading — amber warning lights, stop arm, 10-foot bumper stop, students walking 12 feet away, never backing to a missed stop • Railroad-highway crossings — 15 to 50 feet from the nearest rail, containment (bus length + 15 feet), passive crossings, stall-on-tracks evacuation • Emergency exit and evacuation — when you MUST empty the bus, when students are safer onboard, two older students at each exit • Equipment and post-trip — walk the aisle, sleeping child check, battery box, handicap lift, ABS malfunction lamp • School Bus core — student behavior, high wind, when to back the bus, P + S endorsements HOW TO STUDY 1.
