1. Blue rectangular signs bearing white letters or symbols point out what?
Correct answer: Where services such as fuel, lodging areas, or hospitals can be found
Blue is the color reserved for motorist services, so these signs guide you to things like hospitals, campgrounds, fuel, and rest stops.

2. Why do some railroad crossings display a sign showing a number of tracks?
Correct answer: It warns that several tracks — and possibly several trains — are present
The number tells you more than one set of rails is there, so a second train may be hidden behind the first. Many multi-track crossings carry no such sign, so always check the rails yourself.

3. A square sign showing a white horizontal bar inside a red ball tells a driver what?
Correct answer: Driving into that roadway is prohibited
This is the do-not-enter sign. You are barred from driving into that opening, which is why it appears at exit ramps, at crossovers on divided roads, and along one-way streets.

4. What does a red-and-white triangular sign that points downward require of you?
Correct answer: Slow down and let the other traffic go first
That shape is the yield sign. Reduce speed and let traffic already in the intersection you are crossing, or on the road you are joining, go ahead of you.

5. A round yellow sign marked with a large X and the letters RR warns you of what?
Correct answer: A railroad crossing further along the road
This round yellow sign is posted along the road ahead of a railroad crossing so you have time to slow, look both ways down the rails, and be ready to stop.

6. The white X-shaped "crossbuck" standing at a railroad crossing carries the same meaning as which sign?
Correct answer: A yield sign
The crossbuck functions exactly like a yield sign, so drivers approaching it must give way to any train using the tracks.

7. A red circle with a red slash drawn across a symbol on a sign tells you what?
Correct answer: The maneuver shown in the symbol is not allowed
The circle-and-slash marks something you are forbidden to do, such as turning left, turning right, or making a U-turn at that spot.

8. Most signs that warn of a hazard ahead in New Mexico use which shape and color?
Correct answer: A yellow diamond carrying black symbols or words
Hazard warnings are normally diamond-shaped, yellow, and carry black wording or symbols. They tell you to ease off the gas and be ready to stop for whatever is coming up.

9. How many sides does a stop sign have, and what colors does it use?
Correct answer: Eight sides, red with white lettering
The stop sign is the only eight-sided sign, red with white letters. Halt fully at the sign or the stop line and pull ahead only once crossing vehicles and people on foot are out of the way.

10. Signs posted around road construction, maintenance, or emergency operations use which background color?
Correct answer: Orange
Work-zone signs are orange with black wording or symbols. They warn of crews near the roadway, lowered speeds, detours, slow equipment, and rough or changing pavement.

11. Lights mounted beside a railroad crossing begin flashing back and forth. What must you do?
Correct answer: Stop and wait
Alternating flashes mean a train is on its way, so bring the vehicle to a stop. Never steer around a gate that has come down, and if a bell or horn is sounding, wait until the noise ends.

12. A reflective orange triangle fixed to the back of a vehicle indicates that the vehicle is doing what?
Correct answer: Moving at less than 25 mph
That emblem marks a slow-moving vehicle, meaning one traveling under 25 mph. You will see it on farm machinery, construction equipment, and horse-drawn wagons or carriages.
