Railroad Crossings
26 free questions, part of the School Bus (S) Endorsement CDL practice test
School bus drivers must stop between 15 and 50 feet from the nearest rail at every railroad crossing, per 49 CFR 392.10(a), then look, listen, and cross without stopping or shifting gears on the tracks. Everything else here, active versus passive crossings, cross-bucks, gates, and the "if it won't fit, don't commit" rule, comes from the AAMVA CDL Manual, not a separate federal number. ELDT.io's free bank has 26 questions on this subtopic.

Questions about Railroad Crossings
How far from the tracks does a school bus have to stop at a railroad crossing?
Per 49 CFR 392.10(a), the bus must stop no closer than 15 feet and no farther than 50 feet from the nearest rail.
What's the difference between an active and a passive railroad crossing?
An active crossing has gates, flashing lights, or other automatic warning devices. A passive crossing only has signs, a cross-buck and pavement markings, and the driver alone decides when it's safe to cross.
What does "if it won't fit, don't commit" mean at a railroad crossing?
Per the AAMVA Manual, before crossing, the driver checks that there's enough room on the far side for the bus to fully clear the tracks. If the space beyond the crossing isn't big enough, the driver doesn't start across, even if the way looks clear.
