Core Topics Tested on the Exam

To pass the 20-question written exam, you must score 80% or higher. Our practice tests focus on the five critical safety areas evaluated by state examiners:

  • The 10-Foot Danger Zone: Understanding the areas directly surrounding the bus (front bumper, sides, and rear tires) where students are most at risk of blind-spot accidents.
  • Mirror Adjustment & Clearance: Mastering proper setup for flat, convex, and cross-view (crossover) mirrors to eliminate blind spots and monitor student behavior inside the cabin.
  • Loading & Unloading Procedures: Step-by-step protocols for operating the 8-light amber/red warning system, extending the stop arm, and safely managing student street crossings.
  • Railroad-Highway Grade Crossings: Mandatory “Stop, Look, and Listen” rules, including proper stopping distances (15 to 50 feet), door-opening procedures, and handling passive vs. active tracks.
  • Emergency Evacuations & Student Management: Decision-making protocols for fire, breakdown, or hazard evacuations, maintaining discipline, and managing unruly behavior safely.
