Railroad crossing rules — Tennessee Permit Test
Railroad crossing rules on the Tennessee permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The smaller sign on the post below a crossbuck shows the number of tracks at that crossing.
With two or more tracks, one train passing can hide a second train coming the other way.
They show the number of tracks at a particular crossing.
Flashing lights on a crossbuck mean that a train is coming.
The lights start before you can see the train. Driving on because the track looks empty puts you in its path.
Flashing lights on a crossbuck mean that a train is coming.
If there is more than one track, be sure all tracks are clear before crossing.
When one train clears, a second one can be right behind it on the next track. Starting too soon puts you in front of it.
If there is more than one track, be sure all tracks are clear before crossing.
At a crossing with lights and a gate, stop when the lights begin flashing and before the gate comes down.
A gate coming down on your car can trap you on the tracks. Stopping at the first flash keeps you off them.
Stop when the lights begin flashing and before the gate comes down.
On the test
What does the small sign under a crossbuck tell you?
How many tracks there are. With two or more tracks, one train passing can hide a second train coming the other way. Tennessee Comprehensive Driver License Manual, p.36: “They show the number of tracks at a particular crossing.”
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.
