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
