Why is a school bus at such a disadvantage in a collision with a train?

CDL Manual — School Buses (§10)

Questions are based on Section 10 (School Buses) of the official CDL manual. The School Bus (S) endorsement requires a knowledge test (what we practice here) AND a skills test in a school bus (NOT practiced here), and you must also hold or test for the P passenger endorsement. The knowledge test is given in ENGLISH (real test); our Chinese & Spanish are study aids to help you learn the English material. Federal rules (FMCSA, 49 CFR 391.11) require English proficiency to drive commercially.

    • It has flashing red lights but no gate
    • It is controlled by a police officer
    • It has gates that lower automatically

    Explanation: A passive crossing has no traffic control device, so you must stop and the decision to proceed rests entirely with you. English term: passive crossing (被动式道口 / cruce pasivo).
