Railroad-Highway Crossings — CDL School Bus Tiếng Việt

At a gated crossing, how long must you remain stopped?

📚 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.
