New Mexico lets you retake the knowledge test the same day — but only twice in a week, and a third failure costs you six months. Signs are the section you can make nearly perfect in an evening, which is the cheapest way to avoid ever needing that third attempt.
Our questions describe signs in words rather than showing pictures. Identify one from its shape, color and purpose without seeing it and you have learned the system rather than a set of images.
This quiz pulls 25 questions and scores you at 20. That format is ours, since the MVD does not publish one.
New Mexico Road Signs Test
Learn the system, not the pictures
Shapes
- Octagon — stop, and only stop
- Triangle on its point — yield
- Diamond — a warning about what is ahead
- Pentagon — school zone or crossing
- Round — a railroad crossing is ahead
- Crossbuck — the crossing itself
- Pennant, on the left — a no passing zone begins
Colors
- Red stops or prohibits
- Yellow warns about the road
- Orange means a work zone
- Fluorescent yellow-green means people crossing
- Green gives direction and distance
- Blue lists motorist services
- Brown points to parks and monuments
- White with black text states the law
Two desert hazards the signs actually mean
Dust storms. Visibility can go from clear to nothing in seconds on I-10, I-25 and the open stretches between towns. The correct response is counterintuitive: pull completely off the pavement, stop, turn off all your lights including the hazards, and take your foot off the brake pedal.
Leaving lights on is what causes the pile-ups. A following driver sees taillights, assumes they mark the travel lane, and steers straight at you.
Arroyos and dips. Depth markers beside a dry crossing are not decoration. Monsoon rain fills an arroyo within minutes, and moving water carries vehicles away at depths that look harmless from the driving seat. Turn around and find another route.
Why signs are worth an evening here
The MVD does not publish how many questions the knowledge exam has or what score passes it, so you cannot calculate how many mistakes you can afford. What it does publish is the retake rule, and the second half of it matters:
| Situation | Rule |
|---|---|
| Fail the knowledge test | Retake as soon as you want, even the same day |
| In a single week | No more than twice |
| Three failures | Six months from the date of application |
Signs are the fastest section to make reliable, which makes them the cheapest insurance against ever reaching a third attempt.
Next steps
Once you are consistently above 22 out of 25 here, move to the full New Mexico practice test, which covers the four-year permit, the three-year experience rule for your supervising driver, the driver education requirement that comes before the permit, and the provisional license restrictions. The whole process is on the New Mexico permit guide, or compare states on our states page.
