Railroad signs — Missouri Permit Test
Railroad signs on the Missouri permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
This round advance warning sign tells you that you are nearing a railroad crossing.
It appears before the crossing itself, while you still have room to slow down.
The round advance warning sign tells you that you are nearing a railroad crossing.
This sign is located at the railroad crossing and has the same meaning as a yield sign, so you must yield to trains at crossings.
A train cannot stop for you and cannot steer around you. The yield is not a courtesy.
This sign has the same meaning as a “yield” sign; therefore, you must yield to trains at crossings.
Where this sign stands, you must stop within 15 to 50 feet before the railroad tracks if the red lights are flashing or the gate is down.
Closer than fifteen feet and you are inside the train's sweep. Further than fifty and you cannot see along the track.
You must STOP if the red lights are flashing or the gate is down. You must stop within 15 to 50 feet before the railroad tracks.
Never try to beat a train across the tracks, and never start to cross until there is room for your vehicle on the other side.
The far side is the part people forget. Stopping on the tracks because traffic stopped is how cars are hit.
Never start to cross the tracks until there is room for your vehicle on the other side of the tracks.
On the test
What does this sign tell you?

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.
