Light rail trains — Arizona Permit Test
Light rail trains on the Arizona permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Cars may turn across the METRO light rail tracks only from designated turn lanes controlled by traffic signals.
A light rail train cannot swerve. Turning across the tracks outside a signal-controlled lane can put you in front of one.
Automobiles may turn across the METRO tracks only from designated turn lanes controlled by traffic signals.
Never stop or park your car or bike on light rail tracks.
A train cannot stop in time for a car sitting on the tracks. It will hit it.

Light rail trains are quiet, so look for flashing train headlights and listen for warning bells and horns.
You may not hear a light rail train coming the way you would a freight train. Look and listen both.
Pay attention near the tracks: look for flashing train headlights and listen for warning bells and horns.
The ends of a light rail train look the same; white headlights show it approaching and red taillights show it moving away.
Both ends of the train look alike. The color of the light is how you tell which way it is going.
White headlights show a train approaching, red taillights show it moving away.
Train Approaching signs at METRO light rail intersections flash when a train is approaching the intersection.
The flashing sign is your warning that a train is about to cross. Do not turn onto the tracks.
These electronic signs are posted at all METRO light rail intersections and flash when a train is approaching the intersection.
At METRO light rail intersections, left turns and U-turns are controlled with traffic signals.
The signal holds you back while a train crosses. Turning without it puts you in the train’s path.
Left turns and U-turns are controlled with traffic signals.
On the test
Where may a car turn across the METRO light rail tracks?
From turn lanes with signals. A light rail train cannot swerve. Turning across the tracks outside a signal-controlled lane can put you in front of one. Arizona Driver License Manual and Customer Service Guide, p.48: “Automobiles may turn across the METRO tracks only from designated turn lanes controlled by traffic signals.”
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.
