32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- STOP sign shape
- An octagon, the only eight-sided sign in U.S. traffic control, with a red background and white legend; shape alone identifies the message even when the face is obscured.
- YIELD sign shape
- An inverted (downward-pointing) triangle with a red border and white interior; the unique shape lets drivers recognize the requirement from the back or when the legend is unreadable.
- Warning sign color
- Yellow background with black legend and border, typically on a diamond-shaped panel; used to warn of conditions like curves, intersections, and pavement changes ahead.
- Guide sign colors
- Green for destinations, distances, and route guidance; blue for motorist services such as fuel, food, and lodging; brown for recreation and cultural points of interest.
- Orange sign meaning
- Orange indicates temporary traffic control, including work zones and construction areas; orange signs and channelizing devices guide drivers through or around the activity.
- Yellow pennant sign
- A pennant-shaped yellow warning sign placed on the left side of the road to mark the beginning of a no-passing zone; it supplements the solid yellow center line.
- Yellow circular sign
- A round yellow sign with a black X and RR letters is the railroad advance warning sign, placed in advance of a highway-rail grade crossing.
- Yellow pentagon sign
- A five-sided yellow sign marking a school zone or school crossing; its shape is unique to school-related warnings.
- Crossbuck sign
- A white X-shaped sign with black lettering reading RAILROAD CROSSING, placed at the crossing itself; it establishes the crossing as a yield-to-trains location.
- Regulatory sign purpose
- Regulatory signs give notice of traffic laws or regulations, such as speed limits, turning restrictions, and lane use; they are typically white rectangles with black or red legends.
- Speed limit sign
- A white vertical rectangle with black legend stating the maximum lawful speed; it is a regulatory sign and applies until another speed limit sign changes it.
- Yellow center line
- A yellow line separates traffic traveling in opposite directions; on a two-lane road, yellow center lines divide the two directions of travel.
- White lane line
- White lines separate traffic moving in the same direction, such as lanes on a multi-lane highway or the right edge line of the roadway.
- Broken yellow line
- A dashed yellow center line indicates passing is permitted when safe; the broken line faces the side of the road where passing is allowed.
- Double solid yellow line
- Two solid yellow lines mean passing is prohibited for traffic in both directions; no vehicle may cross the lines to pass.
- Solid and broken yellow
- A solid yellow line paired with a broken yellow line means passing is prohibited only for traffic on the solid-line side; traffic on the broken side may pass when safe.
- Stop line marking
- A solid white bar across the approach lane indicating where vehicles must stop for a stop sign, traffic signal, or crosswalk.
- Crosswalk markings
- White markings that define a pedestrian crossing, either as two transverse lines or a ladder pattern of longitudinal bars; drivers must yield to pedestrians in them.
- Yield line marking
- A row of solid white triangles pointing toward approaching traffic, marking where vehicles must yield before entering an intersection or merging.
- Blue pavement marking
- Blue markings identify accessible parking spaces and access aisles reserved for persons with disabilities; parking there without authorization is prohibited.
- Red pavement marking
- Red markings indicate fire lanes or no-parking zones where stopping and parking are prohibited, often near hydrants or building entrances.
- Edge line purpose
- Edge lines mark the right and left limits of the travelway; a white right edge line and yellow left edge line help drivers keep the vehicle in lane.
- Sign retroreflectivity requirement
- Regulatory, warning, and guide signs must meet minimum maintained retroreflectivity levels or be managed under an assessment or management method per the MUTCD.
- Diamond grade sheeting
- A high-performance retroreflective sign sheeting with microprisms; it returns more light to the driver than engineer grade and is often used on high-speed roads.
- Engineer grade sheeting
- A glass-bead retroreflective sign sheeting with lower performance than high-intensity or diamond grade; used on some low-speed or low-volume roads.
- Flaggers and paddles
- A flagger controls traffic in work zones using a STOP/SLOW paddle or a red flag; the paddle is an octagonal sign on a long handle.
- Channelizing device
- A device such as a cone, drum, or barricade that guides traffic through or around a work zone; orange and white colors signal temporary conditions.
- Advisory speed plaque
- A yellow rectangular plaque below a warning sign stating a recommended speed for the condition, such as a curve; it is advisory, not the legal limit.
- No-passing zone marking
- A solid yellow center line, often paired with a yellow pennant sign, marking a section where passing is prohibited due to limited sight distance.
- Object marker
- A marker placed on or near a fixed object close to the travelway to warn drivers; type 3 markers use yellow and black diagonal stripes.
- Delineator purpose
- A retroreflective post placed along the roadside to indicate the alignment of the road, especially through curves and in low-visibility conditions.
- Interstate route shield
- A red, white, and blue shield sign identifying an Interstate route; even numbers run east-west and odd numbers run north-south in the numbering system.
