NM Road Signs Practice key terms

A sign that states a traffic law, rule, or prohibition drivers must obey, such as a speed limit or stop requirement. These signs are usually rectangular with a white background and black or red legend.

A white rectangular regulatory sign showing the maximum lawful speed in black numerals. It applies from the point posted until another speed limit sign or a different zone changes it.

An eight-sided red sign with a white border and the word STOP in white. Drivers must come to a complete stop at the stop line or crosswalk, yield to traffic and pedestrians, then proceed only when safe.

A downward-pointing triangle with a red border and white center. It requires drivers to slow down and give the right of way to traffic on the intersecting road, stopping only if necessary.

An intersection where every approach has a stop sign, often marked by a smaller plaque reading ALL WAY or 4-WAY. Vehicles arriving together must follow standard right-of-way order rules to proceed safely.

A square red sign with a white horizontal bar and the words DO NOT ENTER. It marks the wrong-way entrance to a one-way road, freeway ramp, or restricted lane and must never be passed.

A red rectangular sign reading WRONG WAY, placed facing traffic that is traveling against the legal direction on a one-way road or ramp. Seeing it means you must stop and turn around immediately.

A black-and-white rectangular sign with an arrow showing that traffic on that road moves only in the arrow's direction. It warns drivers not to enter or travel against the flow.

A regulatory sign that forbids leaving a vehicle unattended in the marked area, though a driver may usually stop briefly to load or unload passengers. It is often paired with time or day restrictions.

A sign prohibiting vehicles from stopping to wait for passengers or freight, allowing only momentary stops to actively load or unload. It is stricter than a no parking sign but looser than a no stopping rule.

An area where parked vehicles may be removed at the owner's expense, indicated by a sign or curb marking. The restriction usually applies during posted hours or to specific vehicle types.

A yellow diamond-shaped sign that alerts drivers to an upcoming hazard or change in road conditions, such as a curve, hill, or narrowing lane. Warning signs advise caution rather than state a law.

A small yellow rectangular sign mounted below a warning sign, showing a safe recommended speed for the hazard ahead, such as a sharp curve. It is a suggestion, not an enforceable speed limit.

A yellow rectangular sign bearing a black arrow-shaped chevron, placed along sharp curves to show the direction of the bend. A series of them guides drivers through the turn, especially at night or in poor visibility.

A yellow diamond warning sign showing a black curved arrow, indicating a bend ahead. A variant with a speed plaque or sharper bend graphic signals a more severe curve requiring reduced speed.

A yellow diamond warning sign showing an arrow joining a through lane, telling drivers that traffic from another lane or ramp will merge ahead. Drivers should adjust speed and position to allow a safe merge.

A yellow warning sign showing a lane ending or narrowing, often with an arrow pointing to the side that continues. Drivers in the ending lane must merge safely into the remaining lane.

A yellow diamond warning sign showing two opposing arrows, alerting drivers that a one-way road is becoming two-way or that oncoming traffic will share the roadway ahead.

A yellow circular warning sign with a black X and two R letters, placed before tracks. It warns drivers to slow down, look, and listen for trains before crossing the rails.

A white X-shaped sign with black lettering reading RAILROAD CROSSING, placed at the tracks themselves. Drivers must yield to trains, and a smaller sign below may show the number of tracks.

A sign that provides directional or informational guidance rather than a rule, such as route numbers, destinations, distances, or services. Guide signs are typically green, blue, or brown depending on their purpose.

A green sign with white lettering used on freeways and major highways to show destinations, distances, exit numbers, and route directions. Drivers read these signs to plan lane changes and exits.

A blue sign with white symbols or text that points travelers to services such as fuel, food, lodging, hospitals, or rest areas. These signs often appear before exits on freeways.

A brown sign with white lettering that identifies parks, historical sites, recreation areas, and cultural points of interest. It helps travelers find attractions and often appears near exits serving them.

A small green panel attached to a guide sign showing the exit's number or mile-based designation. Knowing the exit number helps drivers confirm the correct exit well before the ramp appears.

A red, white, and blue shield-shaped marker displaying an Interstate route number. Even numbers generally run east-west and odd numbers north-south, helping drivers navigate the national freeway network.

A small green sign showing the distance in miles from a state line or other reference point along a highway. Drivers use them to report their location in emergencies and to gauge remaining distance.

An orange diamond-shaped sign warning of road construction, maintenance, or workers ahead. Drivers should slow down, increase following distance, and be prepared for lane shifts or stopped traffic.

An orange diamond warning sign showing a worker holding a flag, indicating that a person ahead is directing traffic through the work zone. Drivers must obey the flagger's signals, which override normal signs and signals.

A posted speed limit, often on an orange or white sign in a construction area, that lowers the maximum lawful speed to protect workers. Fines for violations are frequently doubled when workers are present.

The use of cones, barrels, barricades, arrow boards, and signs to guide traffic safely through or around a work zone. These devices may change lane patterns and override permanent markings.

A cone, drum, or tubular marker used to separate traffic from work areas or to shift lanes. Drivers should not cross these devices, since they mark boundaries that protect workers and motorists.

A large striped barrier used to close a road, lane, or ramp completely to traffic. Its diagonal stripes typically slope downward toward the side on which drivers should pass, when passing is allowed.

A yellow-green diamond or pentagon sign marking an area where children travel to and from school. Drivers must slow down and watch for students, crossing guards, and posted reduced speed limits.

A sign posting a reduced speed limit that applies during school hours or when children are present, often shown with flashing beacons. Drivers must comply whenever the stated condition is in effect.

A marked portion of roadway set aside for pedestrians to cross, indicated by painted lines, a ladder pattern, or a pedestrian sign. Drivers must yield to pedestrians in a crosswalk, marked or unmarked.

A yellow diamond sign showing a walking figure, warning drivers that pedestrians may cross ahead. Drivers should slow down and scan both sides of the road for people entering the crosswalk.

A trained adult, often wearing a reflective vest and using a stop paddle, who stops traffic so students can cross safely near a school. Drivers must obey the guard's signals as they would a traffic signal.

The outline of a sign, which conveys meaning before the legend is read. For example, octagons mean stop, triangles mean yield, diamonds warn, and pentagons mark school zones or school crossings.

A four-sided sign rotated so a point faces up, used almost exclusively for warning signs. Its yellow color and diamond outline tell drivers a hazard lies ahead and caution is needed.

A five-sided sign, commonly used for school zone and school crossing signs. The distinctive outline helps drivers recognize a school-related area quickly, even at a distance or in poor light.

The background hue of a sign, which signals its category: red for prohibitions and stop, yellow for warnings, orange for work zones, green for guidance, blue for services, and brown for recreation.

The text, symbols, or arrows printed on a sign that convey its specific message. Drivers interpret the legend together with the sign's shape and color to understand the required action.
