Traffic light red — New Mexico Permit Test

Traffic light red on the New Mexico permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.

The rules

At a steady red light you must wait until it turns green and there is no crossing traffic before moving ahead.

Cross traffic has the green, and going early puts you right in the path of moving cars.

You must wait until the traffic light turns green and there is no crossing traffic before you may move ahead.
New Mexico Driver Manual, p.4

A small, very bright blinking light in the middle of a red light alerts you to the red light and that you must stop.

The extra flash grabs your eye at a light that drivers might miss or run.

This device is to alert you of the red light and that you must stop.
New Mexico Driver Manual, p.4

You may turn right on a steady red light after a full stop, if it is safe and no sign forbids the turn.

Turning right on red keeps traffic moving, but only after you stop and check that the way is clear.

If you are turning right, you may turn after coming to a full stop, if it is safe to do so and if there is no sign prohibiting the turn on a red light.
New Mexico Driver Manual, p.4

A flashing red light means the same as a stop sign: come to a full stop, then go when it is safe.

A flashing red light is often used where a crossing is risky, so you treat it just like a stop sign.

A flashing RED traffic light means the same as a stop sign.
New Mexico Driver Manual, p.4

A red arrow means you must stop and cannot go in the direction of the arrow until a green arrow or light comes on.

Traffic you would cross has the right-of-way, so turning on a red arrow could cause a crash.

A RED arrow means you must stop and you cannot go in the direction of the arrow.
New Mexico Driver Manual, p.4

On the test

At a steady red light, when may you go straight ahead?

Once it turns green and crossing traffic clears. Cross traffic has the green, and going early puts you right in the path of moving cars. New Mexico Driver Manual, p.4: “You must wait until the traffic light turns green and there is no crossing traffic before you may move ahead.”

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.
