Warning signs — New Mexico Permit Test
Warning signs on the New Mexico permit test — 13 rules, each with the reason behind it and a question on it while it is fresh.
The rules
This warning sign means a cross road is ahead.
Cars may pull out from the side road, so slow down and watch both ways as you near it.
Cross Road
This warning sign means traffic will be merging into your lane ahead.
Another lane of cars is about to join yours, so be ready to adjust your speed and make room.
Merging Traffic
This warning sign means a traffic signal is ahead.
The light may be hidden by a hill or curve, so you need warning to be ready to stop.
Signal Ahead
This warning sign means two-way traffic is ahead.
After a one-way stretch, cars will come at you head-on, so keep to your own side.
Two-Way Traffic
This warning sign means the right lane ends ahead.
Drivers in the ending lane must move over, so make room or merge in good time.
Right Lane Ends
This sign marks a school zone.
Children may dash into the road without looking, so slow down and watch for them.
School Zone
This warning sign means a pedestrian crossing is ahead.
People on foot may be in the road ahead, and they lose badly in any crash with a car.
Pedestrian Crossing
This warning sign means a divided highway begins ahead.
Soon a median will split the two directions, so stay to the right of it.
Divided Highway
This warning sign means the divided highway ends ahead.
Oncoming cars will soon share the road with no median between you, so keep right.
Divided Highway Ends
This warning sign means the road is slippery when wet.
Water makes tires lose grip, so slow down and brake gently when it rains here.
Slippery When Wet
This warning sign means a hill is ahead.
Going down a hill your car gains speed, and big trucks need extra room to slow or stop.
Hill
This round warning sign is placed along the road before you get to a railroad crossing.
It gives you time to slow down and look and listen for a train before you reach the tracks.
with an “X” symbol and black “RR” letters is placed along the road before you get to a railroad crossing.
This sign at a railroad crossing means the same as a yield sign: you must yield to crossing trains.
A train cannot stop or swerve for you, so you are the one who must wait.
This sign has the same meaning as a “Yield” sign.
On the test
What does this sign warn you about?
A road crosses yours ahead. Cars may pull out from the side road, so slow down and watch both ways as you near it. New Mexico Driver Manual, p.5: “Cross Road”
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.
