Emergency notification system sign — Alaska Permit Test
Emergency notification system sign on the Alaska permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The toll-free number on the ENS sign is answered by railroad dispatchers, who try to stop train traffic at the crossing in an emergency.
Only the railroad can stop a train in time, so the call has to reach the people who run the trains.
The toll-free ENS number is answered by railroad dispatchers who are the first line of defense to attempt to stop all train traffic at the crossing during an emergency.
The ENS sign is either on the crossbuck or near the actual crossing.
Knowing where to look means you find the number fast when a car is stuck or a gate is broken.
The sign is either located on the black and white cross buck or near the actual crossing.
Below the dispatch number, the ENS sign carries a Department of Transportation number that identifies the exact location of the crossing.
Reading that number to the dispatcher sends help to the right crossing without guesswork.
Directly below the dispatch number on the ENS sign is a Department of Transportation number that identifies the exact location of the crossing in question.
The ENS number is for reporting unsafe conditions at a crossing, such as malfunctioning warning signals or gates, vehicles blocking the tracks, and trespassers on the tracks.
A broken gate or a stalled truck can kill the next driver, so the railroad needs to hear about it at once.
malfunctions of warning signals, crossing gates and other safety devices at the crossings.
On the test
Who answers the toll-free number on a railroad crossing's ENS sign?
Railroad dispatchers. Only the railroad can stop a train in time, so the call has to reach the people who run the trains. Alaska Driver Manual, p.64: “The toll-free ENS number is answered by railroad dispatchers who are the first line of defense to attempt to stop all train traffic at the crossing during an emergency.”
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.
