Steady signal lights — Arizona Permit Test

Steady signal lights on the Arizona permit test — 8 rules, each with the reason behind it and a question on it while it is fresh.

The rules

A steady yellow light warns that the light is about to turn red; if you have not entered the intersection, come to a safe stop.

The red is coming. Rushing to get through is how drivers end up in the middle when cross traffic starts.

A steady yellow light is a warning that the light is about to turn red.

Arizona Driver License Manual and Customer Service Guide, p.34

If you are already in the intersection when the light turns yellow, keep moving and clear it safely.

Stopping in the middle leaves you in the path of cross traffic when their light turns green.

If you are already in the intersection, you should continue moving and clear it safely.

Speeding up to beat a yellow light is illegal and could cause a crash.

A driver racing the yellow is still in the intersection when the cross street gets its green.

Speeding up to “beat the light” is illegal and could cause a crash.

At a steady red light, come to a complete stop before you reach the intersection, stop line or crosswalk, and stay stopped as long as it is red.

Rolling past the line puts your car in the crosswalk or the cross street, where people and cars have the go-ahead.

You must come to a complete stop before you reach the intersection, stop line or crosswalk.

Where signs do not prohibit it, you may turn right on a red light after coming to a complete stop, when cars and pedestrians are clear.

The turn is allowed only from a full stop. Rolling through the right on red is how pedestrians in the crosswalk get hit.

Where not prohibited by signs, a right turn may be made after coming to a complete stop, when motor traffic and pedestrian traffic are clear.

At a green light, check left and right for cross traffic before entering the intersection, to avoid a car running the red light.

Drivers do run red lights. A quick look both ways is what keeps you from being hit from the side.

Check left and right for cross traffic before entering the intersection to avoid a collision with a red light runner.

You must obey signal lights unless a police officer is directing traffic to do otherwise.

When an officer is directing traffic, the officer knows something the light does not, such as a crash ahead.

You must obey the signal lights unless a police officer is directing traffic to do otherwise.

Traffic signal lights apply to pedestrians and to bicycle and moped riders as well as to motorists.

A cyclist who rides through a red light is breaking the same rule as a driver, and is just as likely to be hit.

These traffic lights apply to pedestrians, bicycle and moped riders, as well as to motorists.

On the test

What does a steady yellow signal light mean?

The light is about to turn red. The red is coming. Rushing to get through is how drivers end up in the middle when cross traffic starts. Arizona Driver License Manual and Customer Service Guide, p.34: “A steady yellow light is a warning that the light is about to turn red.”

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.
