Alaska School Bus CDL Practice Test

The School Bus endorsement (code S) is required for anyone who operates a school bus, in addition to a Passenger (P) endorsement. The school bus exam draws from chapter 10 of the AAMVA CDL Manual and covers the highest-risk areas of school bus operation: danger zone and use of mirrors, loading and unloading at the bus stop, emergency exit and evacuation, railroad–highway grade crossings, student management, antilock brakes, and special safety considerations such as backing and post-trip inspections. The "no-child-left" rule and the safety of children outside the bus are emphasized throughout.
