Sign Shapes at a Glance

• Red octagon = stop, always, no exceptions.
• Red/white triangle = yield.
• Yellow diamond = warning ahead; orange diamond = work zone.
• Yellow pentagon = school zone or crossing.
• Yellow circle = railroad crossing.
• White rectangle = regulatory rule (speed, one-way, etc) — legally binding.
• Green rectangle = guide/direction info like exits and distances.
• Blue = services (gas, hospital, rest area); brown = recreation/history sites.

If you can name a sign from shape and color alone before reading the text, you're studying it correctly.

Right-of-Way in One Breath

First to arrive or stop goes first; ties yield to the right. Left turns yield to oncoming traffic and pedestrians. Pedestrians in a crosswalk always have the right-of-way once they've entered it. On a T-intersection, the terminating road yields to the through road. Roundabout entrants yield to traffic already circulating. Always pull over and stop for emergency vehicles with lights and sirens active, and remain stopped until they've fully passed.

Top Traps

• Assuming posted speed limits are always safe — the basic speed law requires slowing below the limit when weather, traffic, or visibility demands it.
• Forgetting that impairment includes drowsiness, medication, and distraction, not just alcohol — all reduce reaction time and judgment.
• Misreading sign shape under pressure — practice recognizing shape and color before reading any text, since that's how the real test presents scenarios.
• Thinking you can retest the same day after failing — New Mexico requires at least a one-week wait, so first-attempt prep matters.
• Underestimating stopping distance on wet or icy roads — increase following distance well beyond the gap you'd use in dry conditions.
• Forgetting the permit basics: 15 minimum age, $10.00 fee, 4-year validity, and a required 6-month hold before the next step.
