Drawbridges & Railroad Crossings
8 free questions, part of the Passenger (P) Endorsement CDL practice test
A bus must stop between 15 and 50 feet before a railroad crossing, check both ways, and only proceed once it's clear the bus can cross completely without stopping on the tracks. The same stop-and-check rule applies to drawbridges that have no attendant or signal. These procedures come from 49 CFR 383.117(a)(4), and ELDT.io has 8 free practice questions covering the stop distances and the exceptions to the full stop.
Questions about Drawbridges & Railroad Crossings

Between 15 and 50 feet from the nearest rail, under 49 CFR 383.117(a)(4).
What must a bus driver do at a drawbridge with no attendant or signal?
Stop, look to confirm the bridge is down and locked in place, and only then proceed. If there's a signal or an attendant controlling traffic, the driver can slow and check instead of coming to a full stop.
