Railroad crossing signs: crossbucks, gates, and the 15-foot rule
Two white slats forming an X - the crossbuck. Railroad crossings are tested on every state’s permit exam because the consequences of getting it wrong are catastrophic. Trains can’t stop quickly, and a train hitting a car is a fatal crash 80% of the time.
Where you’ll see railroad crossing signs
Wherever a road crosses train tracks. Marked with a crossbuck sign (always), often with flashing red lights and gates that lower for approaching trains.
What to do
Stop between 15 and 50 feet from the nearest rail when a train is approaching, when lights are flashing, when gates are down, or when a flagger or signal indicates stop. Never go around lowered gates - even partially. Don’t shift gears on the tracks.
Common test traps
The ‘no signal but I see a train’ question. Even if no lights are flashing and no gates are down, if you see or hear a train, you must stop and wait. School buses and vehicles carrying hazardous materials are required to stop at every crossing regardless of signals - that’s tested too.
Sample questions on railroad crossing signs

Question 1: How close to a railroad crossing are you prohibited from parking?
- No closer than 50 feet
- No closer than 25 feet
- No closer than 100 feet
Correct: No closer than 50 feet
Why: According to Iowa law, you are prohibited from parking within 50 feet of a railroad crossing. This rule helps ensure visibility and safety for both drivers and trains approaching the crossing.
Question 2: How do gates at railroad crossings function as warning signals in Montana?
- Gates only serve as visual markers and don’t move

- Gates lower to block traffic when a train is approaching
Correct: Gates lower to block traffic when a train is approaching
Why: According to the Montana Driver Manual, gates are listed as one of the railroad crossing warning signs/signals. When activated, these gates physically lower to block the roadway, providing a clear barrier that prevents vehicles from crossing when a train is approaching or passing through the crossing.
