Railroad-Highway Grade Crossings and Vehicle Maintenance

Crossing procedure

Grade-crossing questions reward a strict, repeatable procedure. Slow down, activate hazard lights as appropriate, open the window and turn off noisy devices so you can listen, and look and listen in both directions. Know the difference between passive warnings (crossbucks, pavement markings) and active warnings (flashing lights, gates, bells). Never drive around a lowered gate or past flashing lights, and never stop on the tracks. If your vehicle stalls on the tracks, get everyone off and away immediately and move away from the direction the train would come from.

Traps in questions

A common trap is the assumption that a train's distance or apparent speed makes it safe to cross; trains are closer and faster than they appear. Another is treating a crossing with no gates as safe to cross without stopping. Questions also test whether you know that a bus must stop at crossings in most circumstances, and that stopping is required even when lights are not flashing unless the crossing is exempted.

Vehicle maintenance

Maintenance questions test your role: you are the first line of defense. Report defects promptly, know what is a driver-checkable item versus a shop item, and understand that recurring defects must be documented. Keep the bus clean and free of loose objects that could become projectiles.

Rule of thumb

At any crossing: stop, look, listen, and proceed only when you are certain no train is coming and you can clear the tracks completely. If you cannot clear the tracks, do not start across.
