Railroad stop distance — Louisiana Permit Test
Railroad stop distance on the Louisiana permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Under R.S. 32:171, when you must stop at a railroad crossing, stop no farther than 50 feet from the nearest rail.
Stopping too far back can leave you unable to see the tracks or the signals clearly.
Louisiana law R.S. 32:171 requires that the driver of any motor vehicle must stop within 50 feet but no less than 15 feet from the nearest rail of a railroad crossing when:
Under R.S. 32:171, when you must stop at a railroad crossing, stop no closer than 15 feet from the nearest rail.
A train is wider than its rails. Stopping too close lets it hit the front of your car.
Louisiana law R.S. 32:171 requires that the driver of any motor vehicle must stop within 50 feet but no less than 15 feet from the nearest rail of a railroad crossing when:
You must stop at a railroad crossing when a crossing gate is lowered, a signal is flashing with a train coming, or a train is close enough to be an immediate hazard.
Gates and lights go on because a train is near. A train cannot stop or swerve for you.
Louisiana law R.S. 32:171 requires that the driver of any motor vehicle must stop within 50 feet but no less than 15 feet from the nearest rail of a railroad crossing when:
R.S. 32:171 forbids any driver from stopping a vehicle on railroad tracks.
A car stopped on the rails has no way out if a train comes. Never stop there for any reason.
Louisiana law, R.S. 32:171, prohibits any driver from stopping a vehicle on railroad tracks.
In a line of vehicles at a railroad crossing, do not start across unless you are sure your vehicle can clear the other side.
If traffic stops while you are on the rails, you are trapped. Wait until there is room past the tracks.
If your vehicle is in a line of vehicles approaching a railroad grade crossing, you should not attempt to cross the tracks unless you are certain that your vehicle can safely cross to the other side of the tracks.
If your vehicle stalls or is pinned on the tracks with a train coming, get out and move toward the train, away from the tracks.
When the train hits your car, the pieces fly forward the way the train is going. Moving toward the train keeps you out of that path.
If your vehicle becomes pinned between two vehicles or stalls in the path of an oncoming train, get out and move in the direction toward the approaching train away from the tracks.
Vehicles carrying passengers for hire, school buses, and any vehicle carrying explosives or flammable liquids must stop at railroad crossings.
These vehicles carry many people or things that could explode, so they stop every time. Expect them to stop in front of you.
Drivers of vehicles carrying passengers for hire, school buses or trucks, or any vehicle carrying explosives or flammable liquids must stop at railroad crossings.
On the test
When you must stop at a railroad crossing, what is the farthest from the nearest rail you may stop?
50 feet. Stopping too far back can leave you unable to see the tracks or the signals clearly.

How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
